Forest certification, a proxy for sustainable forest management, covers more than 10% of the world’s forests. Under forest certification, forest managers and landowners must comply with environmental, economic and social management standards aiming to promote forest conservation. Despite an increasing area of certified forests, there is a dearth of data on how forest certification is affecting the conservation of forest ecosystems and associated habitats. 2. Here, we assess the effects of Forest Stewardship Council (FSC) certification, one of the largest certification schemes in the world, on the ecological condition of streams crossing Mediterranean evergreen oak woodlands. 3. We used the Stream Visual Assessment Protocol (SVAP) to compare the ecological condi- tion of streams located in areas with 3 and 5 years of certification, in non-certified areas and in least disturbed streams. 4. Forest certification positively affected the ecological condition of the surveyed streams, but its effects were only measurable after 5 years of certification. Streams with 5 years of certification had more continuous, dense and diverse riparian vegetation when compared to streams located in non-certified areas. Moreover, the condition of streams located in areas with 5 years of forest certification was similar to the condition of least disturbed streams. 5. Synthesis and applications. Forest certification promotes the ecological condition of streams occurring within Mediterranean evergreen oak woodlands. This mainly happens because in areas under forest certification, managers and landowners have to comply with management practices that require them to remove or reduce the main causes for stream deg- radation, allowing riparian habitats to recover. Within landscapes with large and increasing areas under forest certification, such as the Mediterranean cork oak woodlands, the positive effects of certification on the ecological condition of streams may spread across the hydro- graphic network in the medium to long term.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Boudiaf, Imène</style></author><author><style face="normal" font="default" size="100%">Le, Christine</style></author><author><style face="normal" font="default" size="100%">Baudoin, Ezekiel</style></author><author><style face="normal" font="default" size="100%">Galiana, Antoine</style></author><author><style face="normal" font="default" size="100%">Beddiar, Arifa</style></author><author><style face="normal" font="default" size="100%">Prin, Yves</style></author><author><style face="normal" font="default" size="100%">Duponnois, Robin</style></author><author><style face="normal" font="default" size="100%">Le Roux, Christine</style></author><author><style face="normal" font="default" size="100%">Baudoin, Ezekiel</style></author><author><style face="normal" font="default" size="100%">Galiana, Antoine</style></author><author><style face="normal" font="default" size="100%">Beddiar, Arifa</style></author><author><style face="normal" font="default" size="100%">Prin, Yves</style></author><author><style face="normal" font="default" size="100%">Duponnois, Robin</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Soil Bradyrhizobium population response to invasion of a natural Quercus suber forest by the introduced nitrogen-fixing tree Acacia mearnsii in El Kala National Park, Algeria</style></title><secondary-title><style face="normal" font="default" size="100%">Soil Biology and Biochemistry</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">Exotic</style></keyword><keyword><style  face="normal" font="default" size="100%">Invasivity</style></keyword><keyword><style  face="normal" font="default" size="100%">Mimosoideae</style></keyword><keyword><style  face="normal" font="default" size="100%">Nodulation</style></keyword><keyword><style  face="normal" font="default" size="100%">North Africa</style></keyword><keyword><style  face="normal" font="default" size="100%">Rhizobia</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2014</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2014///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.sciencedirect.com/science/article/pii/S0038071713004744http://dx.doi.org/10.1016/j.soilbio.2013.12.030</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">70</style></volume><pages><style face="normal" font="default" size="100%">162 - 165</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">We analyzed the diversity and identity of the rhizobial populations nodulating an invasive Australian legume tree Acacia mearnsii in a natural Quercus suber forest in the El Kala National Park, Algeria. Soils from three different forest plots corresponding to non invaded original Q. suber stand, partially invaded by A. mearnsii, and totally invaded (monodominant) A. mearnsii stand were used to trap nodulating bacteria with the same tree species. Symbiotic nitrogen-fixing bacteria were isolated from root nodules and characterized by sequencing of the internal transcribed spacer region, then submitted to phylogenetic analyses. A total of 67 isolates was obtained, representing the 3 different forest plots, all renodulating A. mearnsii in monoxenic conditions. Phylogenetic analyses showed that all isolates belong to different Bradyrhizobium lineages, according to each of the three locations with little intermixing between forest plots. These results illustrate the adaptation of nodulating Bradyrhizobium populations to the new soil conditions induced by invasion. This symbiotic adaptability is presumed to be a key factor of the invasive character of this tree species.</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Elsevier Ltd</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">De Vita, P.</style></author><author><style face="normal" font="default" size="100%">Serrano, M.

This manuscript aims at describing an approach that may take advantage of a posteriori preference modeling to facilitate the specification of the levels of achievement of various objectives in a typical forest management planning framework. The goal is to provide information about nondominated points in the feasible set in the criteria space (FSCS) so that decisionmakers may take advantage of trade-off information. The emphasis is on demonstrating the potential of adaptive search methods to enhance decisions when three or more criteria are considered. The approach combines the use of mathematical programming and interactive decision maps techniques. It is shown how the estimation refinement method may be used to approximate the Pareto frontier of a typical model I linear programming model. It is further shown how the feasible goals method/interactive decision maps method may be used to retrieve a solution selected by stakeholders from interactive decision maps depicting the Pareto frontier. Results are discussed for a large-scale test application encompassing over 1 million ha of cork and holm oak forest ecosystems in southern Portugal.

A logistic regression approach was used to create habitat models.Results Compared with random points, nests were found to be located farther from roads, villages and patch edges, and in large vegetation patches containing extensive Cork Oak cover on steeper slopes with lower solar radiation. The predictive map revealed that less than 8% of the study area had a greater probability of occupancy than 0.8.Conclusions Most habitats in the study area are unsuitable for nesting suggesting that conservation of the best suitable areas is important.

However, the mechanisms underlying this plasticity are still poorly understood. Among the stress regulators, transcription factors (TFs) are especially important since they can control a wide range of stress-inducible genes, which make them powerful targets for genetic engineering of stress tolerance. Here we evaluated the influence of increasing temperatures (up to 55 °C) or drought (18% field capacity, FC) on the expression profile of an R2R3-MYB transcription factor of cork oak, the QsMYB1. QsMYB1 was previously identified as being preferentially expressed in cork tissues and as having an associated alternative splicing mechanism, which results in two different transcripts (QsMYB1.1 and QsMYB1.2). Expression analysis by reverse transcription quantitative PCR (RT-qPCR) revealed that increasing temperatures led to a gradual down-regulation of QsMYB1 transcripts with more effect on QsMYB1.1 abundance. On the other hand, under drought condition, expression of QsMYB1 variants, mainly the QsMYB1.2, was transiently up-regulated shortly after the stress imposition. Recovery from each stress has also resulted in a differential response by both QsMYB1 transcripts. Several physiological and biochemical parameters (plant water status, chlorophyll fluorescence, lipid peroxidation and proline content) were determined in order to monitor the plant performance under stress and recovery. In conclusion, this report provides the first evidence that QsMYB1 TF may have a putative function in the regulatory network of cork oak response to heat and drought stresses and during plant recovery.</style></abstract><notes><style face="normal" font="default" size="100%">From Duplicate 1 (QsMYB1 expression is modulated in response to heat and drought stresses and during plant recovery in Quercus suber - Almeida, Tânia; Pinto, Glória; Correia, Barbara; Santos, Conceição; Gonçalves, Sónia)From Duplicate 1 (QsMYB1 expression is modulated in response to heat and drought stresses and during plant recovery in Quercus suber - Almeida, Tânia; Pinto, Glória; Correia, Barbara; Santos, Conceição; Gonçalves, Sónia)The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Elsevier Masson SAS&lt;br/&gt;accession-num: 24161757</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Coelho, Marta Baptista</style></author><author><style face="normal" font="default" size="100%">Paulo, Joana Amaral</style></author><author><style face="normal" font="default" size="100%">Palma, João Henrique Nunes</style></author><author><style face="normal" font="default" size="100%">Tomé, Margarida</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Contribution of cork oak plantations installed after 1990 in Portugal to the Kyoto commitments and to the landowners economy</style></title><secondary-title><style face="normal" font="default" size="100%">Forest Policy and Economics</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Carbon Sequestration</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">Kyoto protocol</style></keyword><keyword><style  face="normal" font="default" size="100%">New plantations area</style></keyword><keyword><style  face="normal" font="default" size="100%">Wood</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2012///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://linkinghub.elsevier.com/retrieve/pii/S1389934111001845</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">17</style></volume><pages><style face="normal" font="default" size="100%">59 - 68</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Cork oak stands are a part of the agroforestry ecosystem in Portugal, characterized by a low crown cover from cork oak trees, managed towards cork production, and sometimes in combination with grazing. In recent years, European Union policies gave impetus to a large area of new cork oak plantations, which have been established mainly for cork production purposes, and consequently with higher stand density than traditional agroforestry systems. These plantations are important not only for cork production but also for the carbon sequestered by these slow growing forests that won't be harvested for wood production. Thinning operations will be needed to avoid excessive inter-tree competition and wood extracted from these thinning may also provide income for the owners. In the present study, carbon sequestered and wood volumes resulting from thinning were estimated for the next 70 years. Three scenarios of different annual afforestation rates and different site indexes were tested. The resulting values for the considered scenarios show that, if the plantation rates are maintained, new cork oak plantations will have an important contribution to the Portuguese commitments to providing CO2 offsets under the Kyoto protocol. Additionally, due to the increasing values of initial density in new cork plantations, cork oak forests will produce a signiﬁcant volume of wood that may become an important contribution to the landowners' income.</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Elsevier B.V.</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Welter, Saskia</style></author><author><style face="normal" font="default" size="100%">Bracho-Nuñez, Araceli</style></author><author><style face="normal" font="default" size="100%">Mir, Celine</style></author><author><style face="normal" font="default" size="100%">Zimmer, Ina</style></author><author><style face="normal" font="default" size="100%">Kesselmeier, Jürgen</style></author><author><style face="normal" font="default" size="100%">Lumaret, Roselyne</style></author><author><style face="normal" font="default" size="100%">Schnitzler, Jörg-Peter</style></author><author><style face="normal" font="default" size="100%">Staudt, Michael</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">The diversification of terpene emissions in Mediterranean oaks: lessons from a study of Quercus suber, Quercus canariensis and its hybrid Quercus afares</style></title><secondary-title><style face="normal" font="default" size="100%">Tree Physiology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Algerian oak</style></keyword><keyword><style  face="normal" font="default" size="100%">allozyme polymorphism</style></keyword><keyword><style  face="normal" font="default" size="100%">chemo-taxonomy</style></keyword><keyword><style  face="normal" font="default" size="100%">chemotype</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">isoprene synthase</style></keyword><keyword><style  face="normal" font="default" size="100%">isoprenoid</style></keyword><keyword><style  face="normal" font="default" size="100%">speciation</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2012///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://treephys.oxfordjournals.org/content/32/9/1082.abstract</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">32</style></volume><pages><style face="normal" font="default" size="100%">1082 - 1091</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Interspecific gene flow is common in oaks. In the Mediterranean, this process produced geographical differentiations and new species, which may have contributed to the diversification of the production of volatile terpenes in the oak species of this region. The endemic North African deciduous oak Quercus afares (Pomel) is considered to be a stabilized hybrid between the evergreen Quercus suber (L.) and the deciduous Quercus canariensis (Willd.), presumably being monoterpene and isoprene emitters, respectively. In a common garden experiment, we examined the terpene emission capacities, terpene synthase (TPS) activities and nuclear genetic markers in 52 trees of these three oak species. All but one of the Q. suber and Q. canariensis trees were found to be genetically pure, whereas most Q. afares trees possessed a mixed genotype with a predominance of Q. suber alleles. Analysis of the foliar terpene emissions and TPS activities revealed that all the Q. canariensis trees strongly produced isoprene while all the Q. suber trees were strong monoterpene producers. Quercus afares trees produced monoterpenes as well but at more variable and significantly lower rates, and with a monoterpene pattern different than that observed in Q. suber. Among 17 individuals tested, one Q. afares tree emitted only an insignificant amount of terpenes. No mixed isoprene/monoterpene emitter was detected. Our results suggest that the capacity and pattern of volatile terpene production in Algerian Q. afares populations have strongly diverged from those of its parental species and became quantitatively and qualitatively reduced, including the complete suppression of isoprene production.</style></abstract><issue><style face="normal" font="default" size="100%">9</style></issue><notes><style face="normal" font="default" size="100%">10.1093/treephys/tps06910.1093/treephys/tps069</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>5</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Álvarez-Fernández, Rubén</style></author><author><style face="normal" font="default" size="100%">Ordás, Ricardo-Javier</style></author></authors><secondary-authors><author><style face="normal" font="default" size="100%">Loyola-Vargas, Víctor M.</style></author><author><style face="normal" font="default" size="100%">Ochoa-Alejo, Neftalí</style></author></secondary-authors></contributors><titles><title><style face="normal" font="default" size="100%">Improved Genetic Transformation of Cork Oak (Quercus suber L.)</style></title><secondary-title><style face="normal" font="default" size="100%">Plant Cell Culture Protocols SE - 28</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">AGL1</style></keyword><keyword><style  face="normal" font="default" size="100%">Agrobacterium tumefaciens</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">Fagaceae</style></keyword><keyword><style  face="normal" font="default" size="100%">Herbicide Resistance</style></keyword><keyword><style  face="normal" font="default" size="100%">kanamycin resistance</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber</style></keyword><keyword><style  face="normal" font="default" size="100%">Somatic embryogenesis</style></keyword><keyword><style  face="normal" font="default" size="100%">Tree genetic transformation</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2012///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://dx.doi.org/10.1007/978-1-61779-818-4_28</style></url></web-urls></urls><publisher><style face="normal" font="default" size="100%">Humana Press</style></publisher><volume><style face="normal" font="default" size="100%">877</style></volume><pages><style face="normal" font="default" size="100%">385 - 399 LA -- English</style></pages><isbn><style face="normal" font="default" size="100%">978-1-61779-817-7</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">An Agrobacterium-mediated transformation system for selected mature Quercus suber L. trees has been established.

A previous molecular approach identiﬁed a list of genes potentially important for cork formation and differentiation, providing a new basis for further molecular studies. This report is the ﬁrst molecular characterization of one of these candidate genes, QsMYB1, coding for an R2R3-MYB transcription factor. The R2R3-MYB gene sub-family has been described as being involved in the phenylpropanoid and lignin pathways, both involved in cork biosynthesis. The results showed that the expression of QsMYB1 is putatively mediated by an alternative splicing (AS) mechanism that originates two different transcripts (QsMYB1.1 and QsMYB1.2), differing only in the 5 -untranslated region, due to retention of the ﬁrst intron in one of the variants. Moreover, within the retained intron, a simple sequence repeat (SSR) was identiﬁed. The upstream regulatory region of QsMYB1 was extended by a genome walking approach, which allowed the identiﬁcation of the putative gene promoter region. The relative expression pattern of QsMYB1 transcripts determined by reverse transcription quantitative polymerase chain reaction (RTqPCR) revealed that both transcripts were up-regulated in cork tissues; the detected expression was several times higher in newly formed cork harvested from trees producing virgin, second or reproduction cork when compared with wood. Moreover, the expression analysis of QsMYB1 in several Q. suber organs showed very low expression in young branches and roots, whereas in leaves, immature acorns or male ﬂowers, no expression was detected. These preliminary results suggest that QsMYB1 may be related to secondary growth and, in particular, with the cork biosynthesis process with a possible alternative splicing mechanism associated with its regulatory function.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;accession-num: 23218545</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Marum, Liliana</style></author><author><style face="normal" font="default" size="100%">Miguel, Andreia</style></author><author><style face="normal" font="default" size="100%">Ricardo, Cândido P.</style></author><author><style face="normal" font="default" size="100%">Miguel, Célia</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Reference Gene Selection for Quantitative Real-time PCR Normalization in Quercus suber</style></title><secondary-title><style face="normal" font="default" size="100%">PLoS ONE</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">Gene expression</style></keyword><keyword><style  face="normal" font="default" size="100%">reference genes</style></keyword><keyword><style  face="normal" font="default" size="100%">RT-qPCR (voyant)</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2012///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://dx.doi.org/10.1371/journal.pone.0035113</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">7</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The use of reverse transcription quantitative PCR technology to assess gene expression levels requires an accurate normalization of data in order to avoid misinterpretation of experimental results and erroneous analyses. Despite being the focus of several transcriptomics projects, oaks, and particularly cork oak (Quercus suber), have not been investigated regarding the identification of reference genes suitable for the normalization of real-time quantitative PCR data. In this study, ten candidate reference genes (Act, CACs, EF-1α, GAPDH, His3, PsaH, Sand, PP2A, ß-Tub and Ubq) were evaluated to determine the most stable internal reference for quantitative PCR normalization in cork oak. The transcript abundance of these genes was analysed in several tissues of cork oak, including leaves, reproduction cork, and periderm from branches at different developmental stages (1-, 2-, and 3-year old) or collected in different dates (active growth period versus dormancy). The three statistical methods (geNorm, NormFinder, and CV method) used in the evaluation of the most suitable combination of reference genes identified Act and CACs as the most stable candidates when all the samples were analysed together, while ß-Tub and PsaH showed the lowest expression stability. However, when different tissues, developmental stages, and collection dates were analysed separately, the reference genes exhibited some variation in their expression levels. In this study, and for the first time, we have identified and validated reference genes in cork oak that can be used for quantification of target gene expression in different tissues and experimental conditions and will be useful as a starting point for gene expression studies in other oaks.</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Public Library of Science</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Cubera, Elena</style></author><author><style face="normal" font="default" size="100%">Moreno, Gerardo</style></author><author><style face="normal" font="default" size="100%">Solla, Alejandro</style></author><author><style face="normal" font="default" size="100%">Madeira, Manuel</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Root system of Quercus suber L. seedlings in response to herbaceous competition and different watering and fertilisation regimes</style></title><secondary-title><style face="normal" font="default" size="100%">Agroforestry Systems</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">Dehesa</style></keyword><keyword><style  face="normal" font="default" size="100%">Improved pasture</style></keyword><keyword><style  face="normal" font="default" size="100%">Root density</style></keyword><keyword><style  face="normal" font="default" size="100%">Seedling recruitment</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2012///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.springerlink.com/index/10.1007/s10457-012-9492-x</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">85</style></volume><pages><style face="normal" font="default" size="100%">205 - 214</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Different management practices are commonly applied to increase pasture yield of Mediterranean open woodlands, but the consequences of increasing competition for soil resources with these practices on tree recruitment are still unknown. In a greenhouse study, belowground competition of Quercus suber L. seedlings growing together with natural (OakNP) or improved pasture (OakIP) was evaluated, and their root systems compared with those of seedlings growing in bare soil (OakBS). Two watering levels and two regimes of P2O5 fertilisation were also tested. Because of competition, the OakIP seedlings had their ﬁne root mass density, coarse root length, and shoot mass reduced by up to 40, 36, and 39%, respectively, when compared to OakNP seedlings. OakNP and OakBS seedlings showed similar average root density parameters and shoot mass values, indicating that Q. suber seedlings growing with natural pasture is a low competitive system. High availability of water and phosphorus did not mitigate the strength of competition between herbaceous plants and oak seedlings, and favoured the pasture to the detriment of the trees. Our ﬁndings suggest that P2O5 fertilisation and irrigation practices performed to improve herbaceous productivity will negatively inﬂuence recruitment of Q. suber seedlings.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Lavrov, a</style></author><author><style face="normal" font="default" size="100%">Utkin, a B.</style></author><author><style face="normal" font="default" size="100%">Marques da Silva, J.</style></author><author><style face="normal" font="default" size="100%">Vilar, Rui</style></author><author><style face="normal" font="default" size="100%">Santos, N.

The plant health criterion used is based on the I685 /I740 ratio value, calculated from the fluorescence spectra. The method was benchmarked by comparing the results achieved with those obtained by conventional, continuous excitation fluorometric method and water loss gravimetric measurements.

Results showed that canopy cover strongly shaped macrofungal communities composition and yield. Denser canopy cover enhanced mycorrhizal richness and reduced saprotrophic yield. Furthermore, mycorrhizal richness and yield increased with tree proximity.

In this study, cork oak cover change is investigated in a typical agro-silvopastoral system where the main activities are cereal fodder and wheat cultivation, sheep rearing and cork exploitation. The research method is based on the comparison of two land use maps produced by photo-interpretation of digitised aerial photographs taken in 1954 and 1998, combined with interviews with local farmers, field surveys, and data collected from literature, administrative documentation and decadal censuses (at council level). The results show that the cork oak woodland surface decreased (-29%). It was substituted by other forest, ploughed land, and mixed grassland and shrubland. Apart from the transformation of the cork oak woodland to other forest, other changes have happened probably because of an increase in agricultural and pastoral activities as described by the documental material available for the same area</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>47</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Costa, Joana</style></author><author><style face="normal" font="default" size="100%">Miguel, Célia</style></author><author><style face="normal" font="default" size="100%">Almeida, Helena</style></author><author><style face="normal" font="default" size="100%">Oliveira, Margarida M.</style></author><author><style face="normal" font="default" size="100%">Matos, José a</style></author><author><style face="normal" font="default" size="100%">Simões, Fernanda</style></author><author><style face="normal" font="default" size="100%">Veloso, Manuela</style></author><author><style face="normal" font="default" size="100%">Ricardo, Pinto C.</style></author><author><style face="normal" font="default" size="100%">Paulo, Octávio S.</style></author><author><style face="normal" font="default" size="100%">Batista, Dora</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Genetic divergence in Cork Oak based on cpDNA sequence data</style></title><secondary-title><style face="normal" font="default" size="100%">BMC Proceedings</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">cpDNA (voyant)</style></keyword><keyword><style  face="normal" font="default" size="100%">genetic diversity</style></keyword><keyword><style  face="normal" font="default" size="100%">Populations</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2011</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2011///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.biomedcentral.com/1753-6561/5/S7/P13</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">5</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;periodical: BMC Proceedings&lt;br/&gt;issue: Suppl 7</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Bakkali Yakhlef, Salah Eddine</style></author><author><style face="normal" font="default" size="100%">Abourouh, Mohamed</style></author><author><style face="normal" font="default" size="100%">Ducousso, Marc</style></author><author><style face="normal" font="default" size="100%">Duponnois, Robin</style></author><author><style face="normal" font="default" size="100%">Delaruelle, Christine</style></author><author><style face="normal" font="default" size="100%">Mousain, Daniel</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Intraspecific variability of Pisolithus spp. as a response to changes in soil characteristics in a Moroccan cork oak plantation</style></title><secondary-title><style face="normal" font="default" size="100%">Mycology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">ITS sequencing</style></keyword><keyword><style  face="normal" font="default" size="100%">Morocco</style></keyword><keyword><style  face="normal" font="default" size="100%">Pisolithus</style></keyword><keyword><style  face="normal" font="default" size="100%">soil parameters</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2011</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2011///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.tandfonline.com/doi/abs/10.1080/21501203.2011.592155</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">2</style></volume><pages><style face="normal" font="default" size="100%">283 - 290</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Soil characteristics may be an important factor in structuring fungal communities. We relate the above- and below-ground distribution of the ectomycorrhizal fungi (EMF) Pisolithus spp. to changes in soil chemistry in a Quercus suber plantation located in the Maâmora forest (Morocco). Intrageneric variability of 115 fruit bodies was studied, using morphological characterization, restriction fragment length polymorphism (RFLP) analyses and internal transcribed spacer (ITS) sequencing. Two Pisolithus spp. genotypes were identified: 97% of the fruit bodies represent Pisolithus arhizus; the remaining 3% correspond to Pisolithus species 4, as previously described by Martin et al. [New Phytologist 153 (2002) 345-357]. Multivariate analysis (PCA) showed that species structure was strongly correlated with soil characteristics. P. arhizus fruit bodies were frequently found in the Eastern part of the plot at low molasic clay, N and P contents, while Pisolithus species 4 were collected only in the Western part at the high molasic clay, N and P contents. To determine whether this change in fruit body structure was expressed at the belowground level, we used morphological and molecular techniques to characterize the Pisolithus ectomycorrhizas. Only ectomycorrhizas of P. arhizus were identified at the low P?N?molasic clay site and disappeared completely at the high P?N?red clay site, where no Pisolithus species 4 mycorrhizas were found. However, autocorrelation among soil parameters makes it difficult to isolate the effects of individual parameters. These results show the local-scale impact of natural spatial heterogeneity on an ectomycorrhizal fungal genus.</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><notes><style face="normal" font="default" size="100%">doi: 10.1080/21501203.2011.592155doi: 10.1080/21501203.2011.592155The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Taylor &amp; Francis</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Puyo, Jean-Yves</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">THE CORK OAK FORESTS OF AQUITAINE: CONSERVATION VERSUS ECONOMIC REVIVAL</style></title><secondary-title><style face="normal" font="default" size="100%">SUD-OUEST EUROPEEN</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork oak forests</style></keyword><keyword><style  face="normal" font="default" size="100%">HERTIAGE-MAKING PROCESS</style></keyword><keyword><style  face="normal" font="default" size="100%">MARENSIN</style></keyword><keyword><style  face="normal" font="default" size="100%">NERACAIS</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2010///</style></date></pub-dates></dates><pages><style face="normal" font="default" size="100%">53 - 66</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">THE CORK OAK FORESTS OF AQUITAINE: CONSERVATION VERSUS ECONOMIC REVIVAL.

This paper aims at showing how these groves now become major stakes all the more since there ate so few of them left worldwide and are targeted by multiple projects aiming at either promoting the value of the landscape, sustaining biodiversity, or supporting traditional knowledge (from raising the cork to transforming it) as well as economic worth.

A signiﬁcant interaction was also observed with amino acid nutrition. While some amino acids (i.e., glutamine, arginine or asparagine) did not show signiﬁcant diﬀerences with the controls, a mixture of these three amino acids or gamma amino butyric acid stimulated embryo growth. The highest survival rate during acclimation of plantlets from both somatic and doubled-haploid origin was obtained when the embryos had been previously cultured on basal medium with 3% sucrose and 1% activated charcoal for two months at 4 ◦ C and germinated on medium supplemented with 6-benzylaminopurine and indole-3-butyric acid. • We obtained more than 900 cork oak plantlets acclimated from several embryogenic lines, with a high survival rate, demonstrating that this methodology is applicable for large scale plantlet production.

These gene sequences were isolated through DNA amplification betweenRNaseH conserved motifs and 3’ LTR, based on the structure ofcopia retrotransposons. Phylogenetic analysis revealed that almost all the clones isolated are clustered withCyclops-2, aTy3-gypsy element identified inPisum sativum, except one clustered withgypsy andcopia retroelements found in different species. This suggests the existence of a potential ancestral sequence of theenv gene, prior to the separation ofTy3-gypsy andTy1-copia retrotransposons. Additionally, the isolatedenv-like sequences showed 26–39% of homology withenv-like sequences characterized in viruses.

WildWres are one of the main threats contributing to cork oak decline in the Mediterranean Basin, and one major question that managers face after Wre in cork oak stands is whether the burned trees should be coppiced or not. This decision can be based on the degree of expected crown regeneration assessed immediately after Wre. In this study we carried out a post-Wre assessment of the degree of crown recovery in 858 trees being exploited for cork production in southern Portugal, 1.5 years after a wildWre. Using logistic regression, we modelled good or poor crown recovery probability as a function of tree and stand variables. The main variables inXuencing the likelihood of good or poor crown regeneration were bark thickness, charring height, aspect and tree diameter. We also developed management models, including simpler but easier to measure variables, which had a lower predictive power but can be used to help managers to identify, immediately after Wre, trees that will likely show good crown regeneration, and trees that will likely die or show poor regeneration (and thus, potential candidates for trunk coppicing).</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Almeida, Alice M.</style></author><author><style face="normal" font="default" size="100%">Tomé, Margarida</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Field sampling of cork value before extraction in Portuguese ‘montados’</style></title><secondary-title><style face="normal" font="default" size="100%">Agroforestry Systems</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork quality</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork thickness</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork value</style></keyword><keyword><style  face="normal" font="default" size="100%">Intracluster correlation coefﬁcient</style></keyword><keyword><style  face="normal" font="default" size="100%">Single-stage cluster sampling</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2009</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2009///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.springerlink.com/index/10.1007/s10457-009-9260-8</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">79</style></volume><pages><style face="normal" font="default" size="100%">419 - 430</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The assessment of cork quality and the estimation of cork value are very important to forest landowners, for management purposes and for cork commercialisation. The Forest Producers Associations have been using a sampling scheme with the objective of estimating cork value (price per unit of weight, usually kg) before extraction, based on the sampling of individual trees along a zigzag transect that covers the entire stand. The sampling error is usually too high, but, from a practical standpoint, it is difﬁcult to increase the sampling intensity if it would imply an increase in sampling costs. The aim of this work was to propose, from data collected in six stands representative of the cork oak stands in Portugal, an alternative sampling methodology with a more efﬁcient precision/ cost ratio. Precision and costs of alternative sampling designs based on clusters of different sizes, complemented with analysis of the intracluster correlation coefﬁcient, were studied in order to propose the most adequate sampling strategy. Single-stage cluster sampling with clusters of 5–7 trees guarantees a reasonable sampling error (10–15%) and can be conducted without a large increase in cost.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Celestino, Cristina</style></author><author><style face="normal" font="default" size="100%">Fernandez-Guijarro, B.</style></author><author><style face="normal" font="default" size="100%">Hernández, Inmaculada</style></author><author><style face="normal" font="default" size="100%">López Vela, Dolores</style></author><author><style face="normal" font="default" size="100%">Carneros, Elena</style></author><author><style face="normal" font="default" size="100%">Jiménez García, Jesús</style></author><author><style face="normal" font="default" size="100%">Cardo, L.</style></author><author><style face="normal" font="default" size="100%">Alegre, Jesús</style></author><author><style face="normal" font="default" size="100%">Toribio, Mariano</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Growth data from a field trial of Quercus suber plants regenerated from selected trees and from their half-sib progenies by somatic embryogenesis</style></title><secondary-title><style face="normal" font="default" size="100%">Acta Horticulturae</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">field establishment</style></keyword><keyword><style  face="normal" font="default" size="100%">forest improvement</style></keyword><keyword><style  face="normal" font="default" size="100%">rejuvenation</style></keyword><keyword><style  face="normal" font="default" size="100%">vegetative propagation</style></keyword><keyword><style  face="normal" font="default" size="100%">woody plant micropropagation</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2009</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2009///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.actahort.org/books/812/812_71.htm</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">812</style></volume><pages><style face="normal" font="default" size="100%">493 - 498</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The development of reliable clonal propagation technologies is a requisite for performing Multi-Varietal Forestry (MVF). Somatic embryogenesis is considered the tissue culture based method more suitable for operational breeding of forest trees. Vegetative propagation is very difficult when tissues are taken from mature donors, making clonal propagation of selected trees almost impossible. We have been able to induce somatic embryogenesis in leaves taken from mature oak trees, including cork oak (Quercus suber). This important species of the Mediterranean ecosystem produces cork regularly, conferring to this species a significant economic value. In a previous paper we reported the establishment of a field trial to compare the growth of plants of somatic origin vs zygotic origin, and somatic plants from mature trees vs somatic plants from juvenile seedlings. For that purpose somatic seedlings were regenerated from five selected cork oak trees and from young plants of their half-sib progenies by somatic embryogenesis. They were planted in the field together with acorn-derived plants of the same families. After the first growth period, seedlings of zygotic origin doubled the height of somatic seedlings, showing somatic plants of adult and juvenile origin similar growth. Here we provide data on height and diameter increases after two additional growth periods. In the second one, growth parameters of zygotic seedlings were also significantly higher than those of somatic ones, but there were not significant differences in height increase between seedlings and somatic plants of mature origin. In the third growth period, height and diameter increases of somatic seedlings cloned from the selected trees did not differ from those of zygotic seedlings, which were still higher than data from plants obtained from somatic embryos from the sexual progeny. Therefore, somatic seedlings from mature origin seem not to be influenced by a possible ageing effect, and plants from somatic embryos tend to minimize the initial advantage of plants from acorns.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>13</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Pinheiro, A.

The forest system “montado” is mostly dominated by Mediterranean evergreen oaks such as cork oak (Quercus suber L.) and holm oak (Quercus rotundifolia). The “montado” production system management aims the maintenance of a balanced sustainable land use to cope with the Mediterranean climate variability. One important issue in cork oak forests is the control shrub growth in order to prevent forest fire hazard, which is of high risk in Mediterranean climate. The two most common ways of controlling the shrub component is by mechanical destruction with soil disking (that implicates soil mobilization) or by shrub cutting (that is done with minimum impact on soil). The two referred techniques have different costs and different impacts on cork production and other goods and services (multifunctionality) of cork oak forests. In this paper, the two shrub control systems are compared and the results show that, although soil disking is more profitable than shrub cutting, the results are reversed, if one considers the carbon sequestration. This means that besides the great economic sustainability of cork oak dependence on the price of cork, the profitability of different shrub control methods depend also on the way society valuates other goods and services provided by cork oak forest</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;secondary-title: International Journal of …&lt;br/&gt;periodical: International Journal of …&lt;br/&gt;electronic-resource-num: 10.1504/IJSSOC.2008.022571</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Aranda, I.</style></author><author><style face="normal" font="default" size="100%">Simón, J.

Thus, plants are bound to live in a more enriched CO2 world in a not far-off future. In this new framework, regeneration of forest tree species may be modified as a consequence of the change in the current patterns of seedling response to other environmental resources, such as water or light. We studied the impact of an elevated CO2 concentration on the interaction of drought and light upon the water relations of cork oak (Quercus suber L.) seedlings. In a complete factorial design of contrasting light (HL vs LL), water (WW vs S) and CO2 levels (800 ppm vs 370 ppm), we analysed the influence of each factor and its interaction in the modification of different leaf water parameters in potted seedlings after a 6 months experimental period. These parameters were derived from the construction, with leaf materials, of the P-V curves: osmotic potential at full turgor (Ψπ100), osmotic potential at zero turgor (Ψπ0), modulus of elasticity at full turgor (εmax), and the ratio dry/turgor weight (DW/TW). Doubling of the CO2 levels over the current concentration (380 ppm) did not change any of the studied leaf water parameters, while light and water availabilities had a significant influence. This result does not exclude changes in other basic physiological parameters that could modify the pattern of cork oak regeneration responding to a CO2 enriched atmosphere in the future, and under climatic conditions different to the current ones</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Puértolas, J.</style></author><author><style face="normal" font="default" size="100%">Pardos, M.</style></author><author><style face="normal" font="default" size="100%">Jiménez, M.

Absolute diﬀerences in net photosynthesis between light treatments were higher in well watered than in water stressed seedlings. However, the impact of both factors on overall growth was orthogonal. • We concluded that cork oak development is impaired under deep shade (5% of full sunlight) but it can be optimal under moderate shade (15% of full sunlight) even under moderate water stress.

We also contribute to the technical and political debate on governmental regulations of forest environmental accounting in European Union. We have measured the environmental goods and services consumed by private landowners and public visitors through the contingent valuation technique. We have estimated the value of mushrooms gathering by public visitors in the Scotch Pine Forests of the Sierra de Guadarrama taking the price and harvest from the mushroom market in Pinar Grande (Soria). The value for carbon estimated accounts for the avoided damage of the greenhouse effect mitigation due to the sequestration of the atmospheric carbon dioxide. The environmental valuations show that the private environmental profitability rates in the Alcornocales Natural Park and in the Sierra de Guadarrama are 2.13 % and 3.43 %, in relation to their corresponding land market prices. We have estimated that the total net values added are 1.63 and 3.28 times higher than its corresponding conventional net values added in the Alcornocales Natural Park and in the Sierra de Guadarrama.</style></abstract><issue><style face="normal" font="default" size="100%">729</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Evidente, Antonio</style></author><author><style face="normal" font="default" size="100%">Andolfi, Anna</style></author><author><style face="normal" font="default" size="100%">Fiore, Michele</style></author><author><style face="normal" font="default" size="100%">Spanu, Emanuela</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Diplofuranones A and B , two further new 4-monosubstituted 2 ( 3H ) -dihydrofuranones produced by Diplodia corticola , a fungus pathogen of cork oak</style></title><secondary-title><style face="normal" font="default" size="100%">ARKIVOC</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">canker disease</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">Diplodia corticola</style></keyword><keyword><style  face="normal" font="default" size="100%">phytotoxic metabolites</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber L.</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2007</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2007///</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">2007</style></volume><pages><style face="normal" font="default" size="100%">318 - 328</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Two new 4-monosubstituted 2(3H)-dihydrofuranones, named diplofuranones A and B, were isolated from liquid cultures of Diplodia corticola, a plant pathogenic fungus causing a canker disease of cork oak (Quercus suber L.).

The diplofuranones A and B were characterised, using spectroscopic (essentially NMR and MS techniques) methods, as the 4-[(1E,3E)-5-hydroxyhexadienyl]butan-4-olide and its corresponding 3,4-dihydro side chain derivative. The stereochemistry of the stereogenic secondary hydroxylated carbon of the side chain of diplofuranone A was determined by application of Mosher’s method and proved to be R.

In most cases, the success of the restoration reached only 12%. Sphodroxia maroccana Ley (Melolonthidae) can be considered as the main pest in the restoration parcels. Some traits of the biology of this species are specified, despite shortcomings in the knowledge of the precise period of male emergence with regard to females, the longevity of adults and the sex-ratio. Summer drought, a season without white grub activity, is another main cause of mortality of young plantations. During the first year after plantation in experimental parcels, the cumulated mortality due to these two factors ranged between 41 and 68% according to the blocks in the parcels. The mortality associated with S. maroccana larvae ranged between 24 and 43%, with a distribution of infestation depending on density of young plants. Solid phase micro-extraction used to sample volatiles from the headspace of S. maroccana females allowed to isolate resorcinol (1,3-benzenediol) as presumed female sex pheromone. The role of this molecule has to be demonstrated.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;pub-location: 45 RUE BUFFON, 75005 PARIS, FRANCE&lt;br/&gt;publisher: SOC ENTOMOLOGIQUE FRANCE</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>47</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Celestino, C.</style></author><author><style face="normal" font="default" size="100%">Hernández, I.</style></author><author><style face="normal" font="default" size="100%">Lopez-Vela, D.</style></author><author><style face="normal" font="default" size="100%">Carneros, E.</style></author><author><style face="normal" font="default" size="100%">Alegre, J.</style></author><author><style face="normal" font="default" size="100%">Toribio, M.</style></author><author><style face="normal" font="default" size="100%">Fernandez-Guijarro, B.</style></author><author><style face="normal" font="default" size="100%">Cardo, L.</style></author></authors><secondary-authors><author><style face="normal" font="default" size="100%">Santamaria, JM and Desjardins</style></author></secondary-authors></contributors><titles><title><style face="normal" font="default" size="100%">First data from a field trial of Quercus suber plants regenerated from mature selected trees and from their half-sib progenies by somatic embryogenesis</style></title><secondary-title><style face="normal" font="default" size="100%">Proceedings of the Second International Symposium on Acclimatization and Establishment of Micropropagated Plants</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">field establishment</style></keyword><keyword><style  face="normal" font="default" size="100%">rejuvenation</style></keyword><keyword><style  face="normal" font="default" size="100%">Somatic embryogenesis</style></keyword><keyword><style  face="normal" font="default" size="100%">woody plant micro-propagation</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2007</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2007///</style></date></pub-dates></dates><publisher><style face="normal" font="default" size="100%">INTERNATIONAL SOCIETY HORTICULTURAL SCIENCE</style></publisher><pages><style face="normal" font="default" size="100%">215 - 218</style></pages><isbn><style face="normal" font="default" size="100%">978-90-6605-550-6</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Somatic embryogenesis is considered as the most suitable current regeneration technique for the conservation and genetic improvement of tree species. The ability to induce somatic embryogenesis in leaves from mature trees gives the possibility to compare the performance of the parent trees and their progenies at the same age and place of test. Somatic seedlings were regenerated from five selected cork oak trees and from young plants of their half-sib progenies. They were planted in the field conjointly with zygotic seedlings of these families, to test the comparisons somatic vs. zygotic origin and somatic from mature trees vs. somatic from juvenile seedlings. The effect of genotype and kind of progeny will be studied in a complete factorial design; therefore the field trial comprised 15 treatments arranged in five completely randomised blocks. Each experimental unit included three plants that were distributed following a row and column pattern. Fist survival and height data after six and twelve months of establishment are provided. All plants from seeds survived while almost the half of somatic seedlings died after the winter and they were replaced. Almost 70% of these plants survived after the following summer. There were no differences between somatic seedlings of mature or juvenile origin. Zygotic seedlings doubled the height of the somatic ones after one year in the field, and within these plants those of mature origin grew slightly more than those of juvenile source. Differences due to genotype and family effects were noticeable. No apparent morphological alterations were detected among the three kinds of tested progenies.</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;periodical: Proceedings of the Second International Symposium on Acclimatization and Establishment of Micropropagated Plants&lt;br/&gt;issue: 748&lt;br/&gt;pub-location: PO BOX 500, 3001 LEUVEN 1, BELGIUM</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">CHUST, GUILLEM</style></author><author><style face="normal" font="default" size="100%">GARBIN, LUCAS</style></author><author><style face="normal" font="default" size="100%">PUJADE-VILLAR, JULI</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Gall wasps and their parasitoids in cork oak fragmented forests</style></title><secondary-title><style face="normal" font="default" size="100%">Ecological Entomology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">fragmentation</style></keyword><keyword><style  face="normal" font="default" size="100%">gall wasp</style></keyword><keyword><style  face="normal" font="default" size="100%">parasitism rate</style></keyword><keyword><style  face="normal" font="default" size="100%">parasitoid</style></keyword><keyword><style  face="normal" font="default" size="100%">Pyrenees</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2007</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2007///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://dx.doi.org/10.1111/j.1365-2311.2006.00850.x</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">32</style></volume><pages><style face="normal" font="default" size="100%">82 - 91</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Abstract 1. This paper explores the potential effects of host-plant fragmentation on cork oak gall wasp populations (Cynipidae, Hymenoptera) and on their predators, lethal inquilines, and parasitoids. To address this objective, galls were collected across a gradient of cork oak (Quercus suber) forest fragmentation in the East Pyrenees (Albera, Spain), and they were incubated to obtain the parasitism rates. 2. Two hypotheses were tested: (1) Host-plant fragmentation may induce a decline in gall wasp populations because of area and isolation effects on local extinction and dispersal; as a consequence of that, parasitoids may decline even more strongly in fragmented habitats than their prey. (2) Host-plant fragmentation may cause a decline in gall wasp parasitoid populations that, in turn, can lead to an ecological release in their prey populations. 3. Among the eight cork oak gall wasps sampled in the study area of Albera, the gall abundances of three species (Callirhytis glandium, Callirhytis rufescens, and Andricus hispanicus) were significantly related to forest fragmentation. The overall abundance of gall wasps was affected by a radius of ≈ 890 m surrounding landscape, presenting constant abundances with forest loss until forest cover is reduced at ≈ 40%; below that value the abundance increased rapidly. Three inquilines and 23 parasitoids species were recorded after gall incubation. In 25 cases, species of inquilines and parasitoids were newly recorded for the corresponding host in the Iberian peninsula. 4. Although the overall parasitism rate was high (1.1), it was uncorrelated with fragmentation and with overall cynipid abundance. These results indicate that host-plant fragmentation was correlated with higher abundance of gall wasps, whereas the parasitism rate could not explain this hyper-abundance in small forest fragments.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Blackwell Publishing Ltd</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">López Pantoja, G.</style></author><author><style face="normal" font="default" size="100%">Sánchez-Osorio, I.</style></author><author><style face="normal" font="default" size="100%">Domínguez, L.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">CERAMBICIDOS XILOFAGOS DEENCINAS Y ALCORNOQUES: ESTUDIO BIOECOLOGICO Y CONTROL DEPOBLACIONES</style></title><secondary-title><style face="normal" font="default" size="100%">Bol.

After the analysis of diverse options for population control of insects with similar habits, a strategy of Integrated Management is recommended, having as one of his pillars the attraction of these species for his capture and/or the specific repelence or confusion; that is to say, the applied study of semiochemicals compounds to integrated pest management.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>5</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Alvarez, Rubén</style></author><author><style face="normal" font="default" size="100%">Toribio, Mariano</style></author><author><style face="normal" font="default" size="100%">Cortizo, Millán</style></author><author><style face="normal" font="default" size="100%">Ordás Fernández, Ricardo-Javier</style></author></authors><secondary-authors><author><style face="normal" font="default" size="100%">Wang, K.</style></author></secondary-authors></contributors><titles><title><style face="normal" font="default" size="100%">Cork Oak Trees (Quercus suber L.).</style></title><secondary-title><style face="normal" font="default" size="100%">Methods in molecular biology (Clifton, N.J.)</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">AGL1</style></keyword><keyword><style  face="normal" font="default" size="100%">Agrobacterium tumefaciens</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">Fagaceae</style></keyword><keyword><style  face="normal" font="default" size="100%">kanamycin resistance</style></keyword><keyword><style  face="normal" font="default" size="100%">pBINUbiGUSint</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber</style></keyword><keyword><style  face="normal" font="default" size="100%">Somatic embryogenesis</style></keyword><keyword><style  face="normal" font="default" size="100%">Tree genetic transformation</style></keyword><keyword><style  face="normal" font="default" size="100%">β-glucuronidase</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2006</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2006///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/17033056</style></url></web-urls></urls><publisher><style face="normal" font="default" size="100%">Humana Press</style></publisher><pub-location><style face="normal" font="default" size="100%">Totowa</style></pub-location><volume><style face="normal" font="default" size="100%">344</style></volume><pages><style face="normal" font="default" size="100%">113 - 123</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">A transformation system for selected mature Quercus suber L. trees using Agrobacterium tumefaciens has been established.

This work aims to describe the response of cork oak seedlings to a light gradient in their ﬁrst growing period. The seedlings were grown under different mesh ﬁlters and were watered to full ﬁeld capacity of the soil. The response to different light levels was studied in terms of morphology and growth, measuring heights, diameters, photosynthetic apparatus dimensions and shoot and root biomass. There were three plant extractions in April, June and October. The greatest morphological plasticity was noticed in the size of the leaves, which changed from 1.8 cm 2 under full sunlight to 5.8 cm 2 in maximum shade. The cork oak seedlings endured light levels of 20% at relative growth rates (RGR) similar to those under full sunlight. However, light intensities under 50% produced a smaller accumulation of root biomass. Plants under 5% of light showed clear symptoms of etiolation and their net assimilation rate was practically zero. These results will prove useful in silviculture, for instance, when determining the grade of protection in cork oak reforestations, as well as when deciding the system and period of regeneration and when regulating the liberation cuts of parent trees in stands of cork oak.</style></abstract><issue><style face="normal" font="default" size="100%">1-3</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Dettori, S.</style></author><author><style face="normal" font="default" size="100%">Falqui, A.</style></author><author><style face="normal" font="default" size="100%">Filigheddu, M.

Some 80% of the afforestated surface has been planted with holm oak and cork oak. The latter also characterizes 89% of the reforestation area. Given the funding source, plantations have been established on farmlands. Growth performances of these recent cork oak stands have been quantitatively evaluated and compared with the performances of two experimental plots. In Gallura (north-east of Sardinia), that is the traditional cork production area and still is economically the most important cork district of the island, these new cork oak plantations have an average size of 28 ha. They have been established on lands that, before plantation, were either pastures (30%) or arable lands (70%). Plantation failures are limited to 8.8% of the total (in term of mass) and seem independent of environmental factors or plantations species composition (conifers have been frequently used as secondary species). Average growth of the stem, measured above cork at collar height, is in the range 4 to 8mm/year with a mean value of 5.5mm/year. No correlation appears with either environmental conditions or species composition of the plantations. In the first experimental plot, soil management practices (natural vegetation removal vs its cutting and mulching) does not differentiate young plants growth trends. In the control subplots (no removal) stem collar diameter is 20% smaller. Localized manual hoeing around trunk base increased the diameters by 13% but reduced cork thickness by 21%. The second experimental plot allows comparisons among 27 Mediterranean proveniences of cork oak. The trial exhibits reduced genetic influence: diameters and heights growth are significantly different only among extreme groups. In conclusion, reduced growth performances of the plantations established in farmlands is due, to some extent, to the limitations inherent with private land management (constrained to costs minimization) and, on the other hand, to the generally very limited thickness of Gallura soils. Demand for good quality commercial cork is steadily raising. To sustain the request, in the short term, it would be necessary to extend financial support for plantations care, from 5 to 10 years, or even up to the first stripping (virgin cork).</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;pub-location: Dipartimento di Economia e Sistemi arborei Universit� di Sassari, via E.

Depending on fi re frequency, soil conditions and human uses, these forests present different forms. Even if Mediterranean landscapes have been shaped for a long time by fi re, such recurrent perturbation may affect several functional groups of organisms associated with old forests, such as saproxylics insects. Our aims were (i) to investigate species richness and composition of saproxylic beetle assemblages in different cork-oak stands, (ii) to estimate between stand complementarity and (iii) identify indicator species of each habitat. Three different types of cork-oak stands common in the “Massif des Maures”, representing an increasing gradient of canopy closing and ecosystem maturing, were investigated : a senescent stand associated with mature maquis, an adult stand with high maquis and an open adult stand with low maquis. Beetles were sampled from April to August in 2003 and 2004 using baited window traps. Our results showed that : (i) the three studied cork-oak stands can be considered as three different habitats regarding saproxylic beetle assemblages, (ii) the closed cork-oak stands support the highest cumulative species richness, (iii) abundances of ecological groups show signifi cant between stands differences, (iv) each habitat supports remarkable species from a patrimonial point of view.</style></abstract><notes><style face="normal" font="default" size="100%">APSAPS</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Pintos, B.</style></author><author><style face="normal" font="default" size="100%">Manzanera, J.

Results are discussed for a real world test case – Serra de Grândola, a management area with about 18 600 ha comprising 860 cork oak (Quercus suber L.) land units. Cork oak silviculture adds complexity to the traditional forest management problem. Results show that the devised system is able to address effectively the integration of ecosystem data, silviculture, growth-and-yield and management models.

The addition of 1 lM ABA to the culture medium signiﬁcantly promoted somatic embryo maturation and increased both fresh and dry matter without aﬀecting the relative water content. This eﬀect was parallel to the pattern of variation observed in the endogenous ABA level, which increased from the immature to the mature stage. Endogenous ABA content during the occurrence of secondary embryogenesis was similar to that of the immature stage, showing that embryos with lower ABA levels produced secondary embryos. In contrast, IAA showed the highest concentration during early embryo development and decreased afterwards. Only in somatic embryos subjected to 1-week desiccation followed by stratiﬁcation at 4 C for 2 weeks, was a moderate increment of endogenous IAA content observed. IAA and ABA showed opposite levels during the development and maturation of cork oak somatic embryos and characterised speciﬁc stages of the embryonic development.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Aranda, I.</style></author><author><style face="normal" font="default" size="100%">Castro, L.</style></author><author><style face="normal" font="default" size="100%">Pardos, M.</style></author><author><style face="normal" font="default" size="100%">Gil, L.</style></author><author><style face="normal" font="default" size="100%">Pardos, J. a</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Effects of the interaction between drought and shade on water relations, gas exchange and morphological traits in cork oak (Quercus suber L.) seedlings</style></title><secondary-title><style face="normal" font="default" size="100%">Forest Ecology and Management</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">Drought</style></keyword><keyword><style  face="normal" font="default" size="100%">light</style></keyword><keyword><style  face="normal" font="default" size="100%">osmotic adjustment</style></keyword><keyword><style  face="normal" font="default" size="100%">photosynthesis</style></keyword><keyword><style  face="normal" font="default" size="100%">water use efficiency</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2005</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2005///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://linkinghub.elsevier.com/retrieve/pii/S037811270500085X</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">210</style></volume><pages><style face="normal" font="default" size="100%">117 - 129</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The combined effect of drought and light on different physiological and biochemical traits was assessed in cork oak (Quercus suber L.) seedlings grown under two levels of light availability and submitted to a long-standing drought. Watering was withdrawn after germination and seedlings were allowed to dry to a water content of ca. 50% of ﬁeld capacity. At this point, water-stressed seedlings were grown under moderate drought and two light regimes: high light (HL—50%) and low light (LL— 2%). Soil water in control plants was kept close to ﬁeld capacity (90–100%) for both light environments. Water-relations parameters derived from P–V curves, gas exchange and water status at predawn (Cpd ) were evaluated at twice during the experiment. Nitrogen and chlorophyll contents were determined in the same leaves used for the gas exchange measurements. In addition, maximum rate of carboxylation (Vcmax) and electronic transport (Jmax) were derived from A–Ci curves in well-watered seedlings. The variation on moisture availability during the experiment was the same under both light environments. In control plants, Cpd was over 0.3 MPa at the two harvests, while stressed seedlings decreased to 0.9 MPa, with no differences between light treatments. Water stress decreased osmotic potentials at full (Cp100 ) and zero turgor (Cp0 ). The regressions between both potentials and Cpd showed a higher intercept in shade grown seedlings. This fact will point out the higher osmoregulation capacity in sun seedlings whatever water availability. Nitrogen investment on a per leaf mass (Nmass ), chlorophyll content (Chlmass ) and SLA tended to show a typical pattern of sun-shade acclimation. Thus, the three parameters increased with shade. Only for Nmass there was a signiﬁcant effect of watering, since water stress increased Nmass . LL plants showed a lower photosynthetic capacity in terms of maximum net photosynthesis at saturating light (Amax), which was related to a decrease in Vcmax and Jmax . Both parameters varied with speciﬁc leaf area (SLA) in a similar way. The low-light environment brought about a higher nitrogen investment in chlorophyll, while under high-light environment the investment was higher in carboxylation (Vcmax) and electronic transport ( Fmax). Stomatal conductance to water vapour (gwv ) and Amax were lower in low-light seedlings independently of watering. In addition, there was a trend to keep higher intrinsic water use efﬁciency (IWUE) under high light environment. The increase of IWUE under water stress was higher in HL seedlings. This was as consequence of the steeper decline in gwv as Cpd decreased. The decrease of Amax with Cpd occurred in a similar way in LL and HL seedlings. Thus, the HL seedlings tended to sustain a higher ability to increase IWUE than LL seedlings when they were submitted to the same water stress.</style></abstract><issue><style face="normal" font="default" size="100%">1-3</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Santos, Maria Natércia</style></author><author><style face="normal" font="default" size="100%">Bragança, Maria Helena</style></author><author><style face="normal" font="default" size="100%">Casimiro, Pedro Piloto</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Microrganismos Associados à Cortiça em Diferentes Fases da sua Fileira</style></title><secondary-title><style face="normal" font="default" size="100%">Silva Lusitana</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">associated microorganisms</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">cork stopper manufacture</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2005</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2005///</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">13</style></volume><pages><style face="normal" font="default" size="100%">75 - 93</style></pages><isbn><style face="normal" font="default" size="100%">0870-6352 UL - http://www.scielo.gpeari.mctes.pt/scielo.php?script=sci_arttext&amp;pid=S0870-63522005000100004&amp;nrm=iso</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Several microorganisms have been considered responsible for decrease in cork quality and wine off - flavours. To improve the knowledge on cork microbiology throughout the tree to end product (stopper) steps, the work developed included two components. The first, on fungal populations colonising the tree, aims to evaluate the probable role of the tree as source of both slab and stopper contamination. The second focusing the collection of dispersed information about the microbial populations, throughout the industrial cork steps, has a main objective to constitute a basis for the delineation of further studies on this matter. The integration of results allows the following conclusions: (i) the microbial populations change throughout cork manufacture process, reflecting both the different environmental conditions and methods used; (ii) the persistence of a large part of these populations throughout the several phases (tree to end product), indicates that the tree is, probably one of the most important microorganism source; (iii) a fraction of these populations included in the group are pointed out as capable of producing secondary metabolites that affect both cork and wine quality; (iv) no significant differences between microbial population diversity and tree vigour level were found. The results obtained did not allow a relationship between decrease of tree vigour and wine-off flavours. Dispersed and sometimes inaccurate information makes it difficult to build a consistent knowledge frame, indicating that a well - balanced multidiscipline research program including all the partners involved in cork processing, is an urgent necessity.</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: scielopt</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Díaz-Fernández, Pedro M.</style></author><author><style face="normal" font="default" size="100%">Climent, José</style></author><author><style face="normal" font="default" size="100%">Gil, Luis</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Biennial acorn maturation and its relationship with flowering phenology in Iberian populations of Quercus suber</style></title><secondary-title><style face="normal" font="default" size="100%">Trees</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">iberian peninsula</style></keyword><keyword><style  face="normal" font="default" size="100%">Phenology</style></keyword><keyword><style  face="normal" font="default" size="100%">quiescent flowers</style></keyword><keyword><style  face="normal" font="default" size="100%">ripening cycle</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2004</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2004///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.springerlink.com/index/10.1007/s00468-004-0325-z</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">18</style></volume><pages><style face="normal" font="default" size="100%">615 - 621</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Since the XIX century, there is a controversy about the existence of biennial maturation of the acorns in Quercus suber L. While some authors recognised biennial cycles as an adaptation to habitats with short vegetative periods, other authors discarded the biennial pattern. Successive flowering events from spring to autumn and annual acorn ripening are proposed as an explanation of the multiple acorn crops typical of Iberian forests. To clarify this discussion, the presence of annual and biennial acorns was assessed in seven cork oak stands, covering a wide range of environmental conditions. In each stand, 100 individuals were sampled once in spring and once in autumn. Biennial acorns were observed with variable frequencies in all populations. There was a significant and positive relationship between latitude and the percentage of trees with biennial acorns within northern and central populations. On the contrary, this trend was not significant among southern populations. The hypothesis that the presence of biennial acorns in Quercus suber is related to individual female flowering phenology was confirmed in four populations located in the southwestern Iberian Peninsula. Unregarding local differences in the distribution of phenological stages anticipated trees bore significantly less biennial acorns than delayed individuals of the same stand. This result is coherent with the idea that the length of the vegetative period plays a crucial role in the frequency of annual and biennial acorn ripening patterns. The relationship between annual and biennial ripening cycles and the multiple acorn crops is discussed</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Alvarez, R.</style></author><author><style face="normal" font="default" size="100%">Alonso, P.</style></author><author><style face="normal" font="default" size="100%">Cortizo, M.</style></author><author><style face="normal" font="default" size="100%">Celestino, C.</style></author><author><style face="normal" font="default" size="100%">Hernández, I.</style></author><author><style face="normal" font="default" size="100%">Toribio, M.</style></author><author><style face="normal" font="default" size="100%">Ordás, R.

In the present study, mating-tests and restriction analysis of Internal Transcribed Spacer 1 (ITS1) were used to identify 20 isolates of a Portuguese Armillaria collection. Although the majority of the diploid isolates (80%) could be identified in diploid-haploid pairings, the method is laborious, takes too much time (up to 2 months), and presents a high rate of inconclusive results. The ITS1 region showed to be a reliable molecular marker for A. mellea, in particular when HinfI restriction analysis is applied, since two fragments with 245 bp and 125 bp have been obtained for this most aggressive species whereas 290 bp and 70 bp were produced from isolates of the other European species. As simple molecular techniques are involved and the whole procedure can be performed in one day, A. mellea identification by ITS1 analysis is a clearly accessible and more advantageous tool to plant pathology laboratories, mainly those involved on the control and preservation of forest trees</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: scielopt</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">El Kbiach, Mohamed L'bachir</style></author><author><style face="normal" font="default" size="100%">Lamarti, Ahmed</style></author><author><style face="normal" font="default" size="100%">Abdali, Abdeslam</style></author><author><style face="normal" font="default" size="100%">Badoc, Alain</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Micropropagation du Chêne-liège (Quercus suber L.) par culture d'apex issus d'axes embryonnaires</style></title><secondary-title><style face="normal" font="default" size="100%">Acta Botanica Gallica</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">embryonic axis</style></keyword><keyword><style  face="normal" font="default" size="100%">in vitro culture</style></keyword><keyword><style  face="normal" font="default" size="100%">organogenesis</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2004</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2004///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://dx.doi.org/10.1080/12538078.2004.10515443</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">151</style></volume><pages><style face="normal" font="default" size="100%">401 - 413</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Abstract To improve the in vitro germination and development of cork oak embryonic axes, several mineral media were tested; Durzan medium modified 1/2 supplemented with 400 mg/l glutamine and 3% sucrose gave the best results.

The radial growth curves for cork, wood and stem were very similar, showing a decreasing trend along the production cycle. Cork increment was always the largest fraction of tree growth (on average 74%) and showed less inter-annual variations as compared to wood. Tree radial growth presented a clear within-the-year seasonal pattern, extending from March to October, with a maximum in June-July. The overall pattern of monthly growth distribution was similar among the years of the production cycle, but some inter-annual variations occurred with 1-2 month shifts or monthly growth rate decreases, related to climatic factors.

(199799), an interruption of catkin development was detected in spring 1998. The cause might have been a sharp drop in minimum temperatures during that period, which coincided with the initial stages of microsporogenesis. Results show that environmental temperatures close to 0 ºC halted microsporogenesis and catkinelongation, resulting in their complete death. No fruits were observed in the affected zone, as a possible consequence of the lack of pollen. Phenological, histological, andaerobiological data are analyzed as a whole in order to gain a better understanding of the phenomenon. Cold spells during flowering may be one of the factors influencing the high interannual variability of acorn production in Quercus species.

Previous work in Quercus suber L. using random amplified polymorphic DNA (RAPD) markers showed no genetic variation among somatic embryos within embryogenic lines of zygotic origin. Genetic fingerprinting based on amplified fragment length polymorphisms (AFLP) allows the direct analysis of variation at the entire DNA level by generating more reproducible markers than RAPDs. To confirm the absence of genetic variation within six embryogenic lines of zygotic origin, six primer pairs were selected out of 48 combinations of primers for revealing up to 512 AFLP markers, 301 of them (58.8%) being polymorphic. The mean number of markers per genotype was 375. Again differences were recorded among embryogenic lines, even between those that arose from half-sib zygotic embryos, but no variation was observed among somatic embryos within embryogenic lines. To check variation in embryogenic lines raised from non-embryonic tissues, somatic embryogenesis was induced in expanding leaves collected from sprouts originating in three mature cork oak. DNA was extracted from leaves and from somatic embryos derived from each tree, and three primer pairs showed 165, 110, and 108 markers per genotype/tree, respectively. In one tree, AFLP patterns generated from leaves and somatic embryos were identical, but variation was detected in samples from the other two trees. Although the level of genetic variation detected in these lines (5.6% and 7.3% of polymorphism, respectively) is lower than that recorded for half sibs of cork oak (25%–31%), its influence on phenotypic variation needs further assessment.

The variation of several water parameters was analysed in 2000 from the beginning of the summer to the first rainy period. Predawn water potential (ψama) was measured on 5 dates on 6 plants per provenance. On the same plants, pressure-volume curves were carried out on twigs from the spring flushing. Several parameters related to responses to drought were estimated: osmotic potential at full turgor (ψπ 100) and at the loss turgor point (ψπ 0), relative water content at zero turgor (CHR0) and elastic modulus at maximum turgor (εmax). Afterwards osmotic and elastic adjustments were evaluated, and the response to drought was separated of the influence of other factor such as phenology. When the water parameters were analysed, there were not significant differences among provenances, meanwhile the differences among dates were highly significant. A decrease in ψπ 100 and an increase of tissue rigidity (εmax) were observed during the period of water stress. The response to drought overlapped with variations due to ontogenic factors.</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;periodical: III Congreso Forestal Español Congreso</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Bueno, M.

Results centre on a new pollen record of Navarrés (Valencia, eastern Spain), which shows that the cork oak survived regionally during the Upper Pleistocene and was important during a mid-Holocene replacement of a local pine forest by Quercus-dominated communities. This phenomenon appears linked to the recurrence of ﬁre and reinforces the value of the cork oak for reforestation programmes in ﬁre-prone areas. In addition to Navarrés, other Late Quaternary pollen sequences (Sobrestany, CasablancaAlmenara, Padul, SU 8103, SU8113, 8057B) suggest last glacial survival of the cork oak in southern and coastal areas of the Peninsula and North Africa. Important developments also occur from the Late Glacial to the middle Holocene, not only in the west but also in the eastern Peninsula. It is suggested that, in the absence of human inﬂuence, Q. suber would develop in non-monospeciﬁc forests, sharing the arboreal stratum both with other sclerophyllous and deciduous Quercus and Pinus species</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Boavida, L.

To the best of our knowledge, this report provides the first insight into the sexual reproduction cycle in this species. The cork oak flowering season extends from April until the end of May. Our results show that, at anthesis, the pistillate flower is not completely formed and ovules are just starting to develop. Pollen reaching the dry stigmatic surface adheres to the receptive cells, germinates and penetrates the epidermis in aproximately 24 h, and grows through the intercellular spaces of a solid transmitting tissue. In cross-pollination, a sequential arrest of pollen tubes was observed along the style, providing preliminary evidence for a pollen tube competition mechanism. As a consequence, few pollen tubes reach the basal portion of the style. Furthermore, pollen tube growth is a discontinuous process since tubes are arrested in the basal portion of the style about 10–12 days after pollination. While tubes are latent, the ovarian loculus starts to develop from an emerging mass of sporogeneous cells which later will differentiate into the placenta and ovules. One and a half months after pollination ovules complete their differentiation, tubes resume growth and fertilisation occurs. Ovular abortion is frequent at this stage, and only one ovule will successfully mature during autumn into a monospermic seed.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>47</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Bueno, A.</style></author><author><style face="normal" font="default" size="100%">GÓMEZ, A.</style></author><author><style face="normal" font="default" size="100%">Boscaiu, M.</style></author><author><style face="normal" font="default" size="100%">Manzanera, J.

The same conditions had been shown previously to be optimal for embryogenic induction in isolated microspore cultures of several model species such as tobacco and wheat. These results support the notion that stress, particularly sucrose starvation, a heat shock or a combination of both treatments could be the major and general signal responsible for the inhibition of normal gametophytic development of the microspores and for the induction of the alternative embryogenic pathway.

First experiment. Immature somatic embryos of 2 mm. length were cultured for 30 days in four different growing media: 1/2SH{*}, SH{*}, 2xSH{*} and MS, both in solid and liquid phase. Higher fresh weights were detected, in every media, using liquid culture. In relation to developmental pattern, liquid culture in 1/2SH{*} has demonstrated to be the most effective combination for the first developmental stages producing lower percentages of secondary embryogenesis. Second experiment. Immature somatic embryos were cultured for 15 days in liquid 1/2SH{*} and transferred to the four different media. The richest media were shown to be more appropriated for the maturation stage giving higher rates of mature embryos.</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;periodical: HORTICULTURAL BIOTECHNOLOGY IN VITRO CULTURE AND BREEDING&lt;br/&gt;issue: 447&lt;br/&gt;pub-location: PO BOX 500, 3001 LEUVEN 1, BELGIUM</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>47</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Garcia-Martin, G.</style></author><author><style face="normal" font="default" size="100%">Fernandez-Galiano, E.</style></author><author><style face="normal" font="default" size="100%">Mauri, P.

The seed proteins, which constitute approximately 5% of the seed weight, are glutelins on the basis of solubility criteria. They are readily solubilized in sodium borate buffer, pH 10, 50 mM, containing 1% (v/v) ?-mercaptoethanol and 1% (w/v) sodium dodecyl sulfate. This fraction is made up of a large number of polypeptides with molecular masses ranging from 10 to above 100 kDa and occurs in the form of large aggregates. The level of glycosylation is low, with two main glycopolypeptides present (43 and 65 kDa). However, the major polypeptides are not glycosylated. In vitro digestibility studies indicated that trypsin and α-chymotrypsin produce a partial proteolysis of the cotyledonary proteins, particularly among the larger molecular mass polypeptides. The partial proteolysis seen in trypsin digests is not due to the presence of enzyme inhibitors in the seeds. On the other hand, pepsin almost completely digests the seed proteins. Taken together, these results may be considered as a good indication of the potential nutritional quality of the proteins from Q. suber seeds.

The same conditions had been shown previously to be optimal for embryogenic induction in isolated microspore cultures of' several model species such as tobacco and wheat. These results support the notion that stress, particularly sucrose starvation, a heat shock or a combination of both treatments could be the major and general signal responsible for the inhibition of normal gametophytie development of the mierospores and for the induetion of the alternative embryogenic pathway.

A two- stage process, in which benzyladenine and naphthaleneacetic acid were added first at high and then at low concentrations, was required to initiate the process. Somatic embryos arose when the explants were subsequently placed on medium lacking plant growth regulators. The embryogenic lines remained productive, by means of secondary embryogenesis, on medium without growth regulators. However, this repetitive induction was influenced by the macronutrient composition of the culture medium. Both low total nitrogen content and high reduced nitrogen concentration decreased the percentage of somatic embryos that showed secondary embryogenesis. Our results suggest that alternate culture on medium that increases embryo proliferation and a low salt medium prohibiting embryo formation will partially synchronize embryo development. Chilling slightly reduced secondary embryogenesis but gave a modest increase in germination. Maturation under light followed by storage at 4 °C for at least 30 days gave the best results in switching embryos from an embryogenic pathway to a germinative one. Under these conditions 15% of embryos showed coordinated root and shoot growth and 35% formed either shoots or mostly roots. These percentages were higher than those of embryos matured in darkness. This result indicates that a specific treatment is required after maturation and before chilling to activate the switch from secondary embryo formation to germination.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">VARELA, M.

Gene conservation of species accompanying Quercus suber, or even dependent on Quercus suber, is a third objective. The suggested sampling of gene resource populations is mainly based on climatic, soil and management conditions of Quercus suber populations. Active selection of trees with good cork in small multiple populations growing over a broad array of site conditions is suggested to match the joint evolutionary and breeding objective in gene conservation. Management of large natural populations to create maximum habitat diversity is suggested to take care of the gene conservation of accompanying species.

In the field of propagation, the characteristics of sexuai reproduction are discussed. The author recommends the use of medium or small acorns and empbasizes the need of improving acorn storage procedures. Considering vegetative propagation as the best method to obtain maximal genetic gains, the author emphasizes the difficulties found in the use of cuttings, the fairly good results obtained with grafts, and the promising experiences of tissue culture. The importance of rejuvenating techniques using stump sprouts and suckers for vegetative propagation is strongly emphasized. The selection superior trees for breeding programs in the cork oak is difficult because of the lack of previous experience in genetics of bark production. An experimental method, developed in the province of Cidiz with the help of ICONA, is described.

Plant material was collected during the embryo development season, from June to September. Immature embryos proved to be the most reactive initial explant. Callus and somatic embryos developed a few weeks after the beginning of the 2,4-D treatment. For embryo development experiments, different growth regulators and cold and desiccation treatments were tested. Cold storage of somatic embryos matured in vitro at 5°C was the best treatment for breaking dormancy.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Blackwell Publishing Ltd</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">González Adrados, J.

For Many years no pests were noted. In 191R the twig wasp Plagiotrochus suberi Weld, not described until 1926, was observed injuring the tree in California. It has since become a pest, particularly when the cork oak is planted as an ornamental or shade tree. The larvae feed within a jellylike matrix in the small twigs. The resulting dead twigs on the infested trees pn,- sent an unsightly, brushy appearance. The wasp has 1 generation a year. The agamic females emerge from the twigs via a small round hole in May. They are very weak fliers and remain close to the twigs on which they originated. Oviposition is in the twig growth of the previous year. The eggs hatch in late summer and the larvae develop slowly, pupating the following April. The insect has been found in Switzerland and Portugal (where it probably originated) only in the past few years. The time and manner of introduction into California are not known. In North America the wasp is found only in California. Only moderate control has been obtained with sprays of lindane and carbaryl directed against the adult stage. A European aphid, Myzocallis borneri Stroyan, is now a pest of the cork oak in California. This record is new. Other insect pests of the tree in this country are of very minor importance.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;label: California;Plagiotrochus suberi;cork oak;twig wasp (PG)</style></notes></record></records></xml>
