Changes in agricultural activities, the traditional driver of the economy in this region, led to new land uses such as long-term set aside (shrublands) and eucalyptus plantations. A study was conducted on the oak woodland landscape dynamics over a 50-year period (from 1958 to 2007) in order to assess the effect of different biophysical conditions on landscape spatial changes, and to identify the resilience of lanscape composition to different disturbances (e.g., socio-economic changes and wildfires). Land use changes over two consecutive periods (1958-1995 and 1995-2007) were inferred by spatial analysis of land cover data (aerial photographs) and related to landscape physical attributes (slope and soil type). A transition matrix of four vegetation land-cover classes was obtained, allowing the assessment of the landscape composition changes bewteen the two above periods. Results showed that lansdcape in 1958 was largely occupied by open farmland, with large patches of open oak woodlands on steep slopes surrounding watercourses. Open farmland and shrubland drastically declined from 1958 to 1995, while eucalyptus plantation exhibited a dramatic expansion. Although large areas of cork oak forest turned into eucalyptus plantation, the net loss of oak forest was low and counterbalanced by its increment on former open farmland. The occurrence of a wildfire in 2003 promoted a dramatic decrease in cork oak woodlands, which mostly turned into shrubland. However, shrubland may be considered &amp;#8220;safe sites&amp;#8221; for ecological succession, ensuring natural cork oak regeneration and the colonization of neighboring areas.</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%">Costa, Augusta</style></author><author><style face="normal" font="default" size="100%">Madeira, Manuel</style></author><author><style face="normal" font="default" size="100%">Plieninger, Tobias</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Cork oak woodlands patchiness: A signature of imminent deforestation?</style></title><secondary-title><style face="normal" font="default" size="100%">Applied Geography</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Forest degradation</style></keyword><keyword><style  face="normal" font="default" size="100%">Fractional canopy cover</style></keyword><keyword><style  face="normal" font="default" size="100%">mediterranean landscape</style></keyword><keyword><style  face="normal" font="default" size="100%">Patch size–frequency distribution</style></keyword><keyword><style  face="normal" font="default" size="100%">Power-law function</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%">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/S0143622814001623</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">54</style></volume><pages><style face="normal" font="default" size="100%">18 - 26</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The cork oak (Quercus suber L.) woodlands of the agroforestry landscapes of Southwestern Iberia are undergoing drastic change due to severe natural and anthropogenic disturbances. These may eventually result in woodland loss or deforestation, the final step of an ongoing process of woodland degradation. Monitoring changes in the spatial patterns of woodlands – especially fractional canopy cover of woodlands and/or their patchiness in the landscape mosaic – potentially enables forecasting of loss and responding to it at an early stage. We examine the degradation process in two cork oak woodlands, resulting from distinct disturbances, wildfire and oak mortality, aimed at evaluating the changes, trends and deviations of the spatial attributes of these woodlands as they move from an initial (less disturbed ecosystem) to a final state (more disturbed ecosystem). While undergoing disturbances, both woodlands exhibited similar trends of decreasing fractional canopy cover and decreasing number of larger patches. Patchiness rather than fractional canopy cover seems, however, to be potentially more useful as a signature of imminent oak woodlands deforestation, given that its contrast before and after disturbance was much higher. The structural dynamics of oak woodlands is a crucial but neglected issue that needs greater attention from policy forums working toward their conservation and restoration as well as from stakeholders and society as a whole.</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%">de Sampaio e Paiva Camilo-Alves, Constança</style></author><author><style face="normal" font="default" size="100%">Clara, MariaIvoneEsteves</style></author><author><style face="normal" font="default" size="100%">Almeida Ribeiro, NunoManuelCabral</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Decline of Mediterranean oak trees and its association with Phytophthora cinnamomi: a review</style></title><secondary-title><style face="normal" font="default" size="100%">European Journal of Forest Research</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">mortality</style></keyword><keyword><style  face="normal" font="default" size="100%">pathogenes</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus ilex L.</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber L.</style></keyword><keyword><style  face="normal" font="default" size="100%">tree decline</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2013</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2013///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://dx.doi.org/10.1007/s10342-013-0688-z</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">132</style></volume><pages><style face="normal" font="default" size="100%">411 - 432</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Mortality events in cork and holm oaks have occurred in the Mediterranean basin since the beginning of the XX century, but severity of decline increased during the 1980s. By that time, the exotic soil borne pathogen Phytophthora cinnamomi was often recovered from declining stands and since then it has been considered the main factor associated with decline. This work analyses data concerning P. cinnamomi surveys in cork and holm oaks trees, pathogenicity tests carried out in controlled experiments, studies about the influence of site characteristics in tree decline and approaches to control the disease. Results of field surveys showed that the pathogen is widespread and pathogenicity tests suggested that host susceptibility to the pathogen is moderate when seedlings are in appropriate watering conditions, particularly cork oaks. Occurrence of decline is also associated with soil characteristics that interfere with root expansion and water retention. We assessed the relative importance of each factor involved in decline and revised the role of P. cinnamomi in cork and holm oak decline.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><notes><style face="normal" font="default" size="100%">APSAPSThe following values have no corresponding Zotero field:&lt;br/&gt;publisher: Springer-Verlag</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 MUR, C.</style></author><author><style face="normal" font="default" size="100%">RUIZ-GALEA, M.</style></author><author><style face="normal" font="default" size="100%">ALONSO BLÁZQUEZ, N.</style></author><author><style face="normal" font="default" size="100%">BARRA JIMÉNEZ, A.</style></author><author><style face="normal" font="default" size="100%">ALEGRE ÁLVARO, J.</style></author><author><style face="normal" font="default" size="100%">TORIBIO IGLESIAS, M.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Establecimiento de cultivos en suspensión para la producción en masa de embriones somáticos en alcornoque y pino piñonero</style></title><secondary-title><style face="normal" font="default" size="100%">VI Congreso Forestal Español</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Biotecnología forestal</style></keyword><keyword><style  face="normal" font="default" size="100%">embriogénesis somática</style></keyword><keyword><style  face="normal" font="default" size="100%">Pinus pinea L.</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%">2013</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2013///</style></date></pub-dates></dates><pages><style face="normal" font="default" size="100%">1 - 11</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">La clonación mediante embriogénesis somática es hoy una biotecnología bien establecida en la industria forestal, posibilitando la regeneración de plantas a partir de individuos selectos y el establecimiento de plantaciones multivarietales de alto valor productivo. El potencial de esta biotecnología se ve condicionado por la recalcitrancia que muestran algunas especies, genotipos o explantos para responder a las condiciones de cultivo impuestas. La producción a gran escala de embriones somáticos requiere el establecimiento de cultivos en suspensión, los cuales proporcionan mayores tasas de producción y sincronización de los embriones somáticos que las obtenidas en medio semisólido, prerrequisito para la automatización de esta biotecnología. Hemos obtenido la regeneración de plantas por embriogénesis somática en medios semisólidos, usando brotes de hojas de alcornoque y a partir de semillas inmaduras en pino piñonero. También hemos establecido cultivos en suspensión en ambas especies. Se describe, entre otros factores, el efecto de la densidad de inoculación, el volumen del envase y la velocidad de agitación, en la proliferación de líneas embriogénicas y diferenciación de embriones somáticos para ambas especies. El tamaño y la densidad del inóculo determinaron fuertemente el crecimiento de los cultivos. La velocidad de agitación y las características del envase influyeron sobre todo en la organización de las estructuras embriogénicas.</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;periodical: VI Congreso Forestal Español&lt;br/&gt;pub-location: Vitoria</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%">Pintor, Ariana M.

The structures of thirty three compounds were tentatively identiﬁed by liquid chromatography coupled to electrospray ionisation mass spectrometry (HPLC–DAD/ESI–MS). The majority of those compounds were gallic acid derivatives, in the form of either galloyl esters of glucose (gallotannins), combinations of galloyl and hexahydroxydiphenoyl esters of glucose (ellagitannins), dehydrated tergallic-C-glucosides or ellagic acid derivatives. Others were found to correspond to low molecular weight phenolic compounds, like acids and aldehydes. Mongolicain, a ﬂavanoellagitannin in which hydrolysable tannin and ﬂavan-3-ol moieties are connected through a carbon–carbon linkage, was also detected in cork from Q. suber L. The results illustrate the rich array of phenolic compounds present in cork.</style></abstract><issue><style face="normal" font="default" size="100%">4</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%">BOUCHAOUR-DJABEUR, Sabéha</style></author><author><style face="normal" font="default" size="100%">BENABDELI, Khéloufi</style></author><author><style face="normal" font="default" size="100%">Bejamaa, Mohamed Lahbib</style></author><author><style face="normal" font="default" size="100%">Stiti, Boutheina</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Déprédation des glands de chêne liège par les insectes et possibilités de germination et de croissance des semis</style></title><secondary-title><style face="normal" font="default" size="100%">Geo-Eco-Trop</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">aspects of the acorns</style></keyword><keyword><style  face="normal" font="default" size="100%">Growth</style></keyword><keyword><style  face="normal" font="default" size="100%">infest by the insects</style></keyword><keyword><style  face="normal" font="default" size="100%">period of harvest</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber L.</style></keyword><keyword><style  face="normal" font="default" size="100%">resistance</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><volume><style face="normal" font="default" size="100%">35</style></volume><pages><style face="normal" font="default" size="100%">69 - 80</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Depredation of the acorns cork oak by the insects and its impact on the potential of germination and seedling growth were studied in a mountain cork oak forest in northwestern Algerian. The rate of pre-germinated acorns on the ground is higher than for other acorns. The weight is the most distinctive variable for all the acorns; whatever their condition and provenance, it varies significantly from 0.76 to 6.76 g. Regarding the damage to acorns, statistical tests show no significant difference in the length and weight, it is not very significant for the width.The infestation of acorns is independent of their size. The acorns attacked by beetles are clearly dominant (72%) compared with those attacked by moths (28%). 20% severely damaged acorns germinate and produce viable seedlings. But the germination rate decreases with the increase of injuries. Growth is strongly affected by the rate of damage to acorns. One therefore concludes that a major attack in the cotyledons certainly does not act on germination, but can affect the strength of the resulting plant and its survival.</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%">Azul, Anabela Marisa</style></author><author><style face="normal" font="default" size="100%">Mendes, Sara Margarida</style></author><author><style face="normal" font="default" size="100%">Sousa, José Paulo</style></author><author><style face="normal" font="default" size="100%">Freitas, Helena</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Fungal fruitbodies and soil macrofauna as indicators of land use practices on soil biodiversity in Montado</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%">Ecosystems monitoring</style></keyword><keyword><style  face="normal" font="default" size="100%">Fungal fruit-body</style></keyword><keyword><style  face="normal" font="default" size="100%">fungal fruit-body á soil</style></keyword><keyword><style  face="normal" font="default" size="100%">land use</style></keyword><keyword><style  face="normal" font="default" size="100%">macrofauna á</style></keyword><keyword><style  face="normal" font="default" size="100%">montado</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber L.</style></keyword><keyword><style  face="normal" font="default" size="100%">soil macrofauna</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.springerlink.com/index/10.1007/s10457-010-9359-yhttp://link.springer.com/10.1007/s10457-010-9359-y</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">82</style></volume><pages><style face="normal" font="default" size="100%">121 - 138</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The impacts of land use on soil biodiversity are still poorly understood, although soil fungi and macrofauna are recognized to provide beneÞts to ecosystems. Here, we tested whether land use practices used to control shrub density inßuences the fruiting macromycetes (ectomycorrhizal-forming fungiÑ ECMFÑand saprobes) and soil macrofauna diversity and abundance in Montado ecosystems. To address this inßuence, we conducted a 2-yearsÕ period monitoring of fungi fruitbodies and macrofauna in sixteen experimental plots in Montado landscape in southern Portugal. A total of 4,881 frutibodies (57 taxa of ECMF and 64 taxa of saprobic fungi) and 3,667 soil invertebrates (73 species and morphospecies) were monitored in the experimental plots. There was greater losses in sporocarps production and taxa composition, particularly the ECMF, in plots where shrub density was controlled by permanent grazing (Ca) or involving cutting practices followed by soil tillage (M), in comparison with cutting practices with no soil tillage (Cu) and the control (C). The ECMFLaccaria laccata and Xerocomus subtomentosus exhibited a close relation with C and Cu plots while the saprobes, e.g., Entoloma conferendum, were associated to Ca and M plots. Most species associated to Cu plots were present in C plots during the 2 years, but not in Cu after the cutting practices (in the second year of sampling). Regarding soil macrofauna, higher values of taxa and species richness were observed in C and Cu plots in the Þrst year of sampling. The ant species Aphaenogaster senilis and several Staphylinid morphospecies exhibited a close relation with M plots, whilst most spider families were directly associated to C and Cu plots. After the shrub cutting practices, higher values of taxa and species richness of soil macrofauna were observed in M and Ca plots; the presence of species with a high competitive ability to colonize disturbed areas faster might explain the results. Contrary to the frutibodies production and diversity, species richness and abundance within soil macrofauna were identical between Cu and C in 2004.

Despite the perception of increasingly visible damage in oak woodlands on drought-prone sites, the role of the various environmental factors in their decline is not clear. • To describe the spatial patterns of cork oak (Quercus suber L.) mortality, a cork oak mortality index (MI) was determined for each landscape feature (agroforestry system, soil type, slope and aspect) using a GIS approach. To achieve this goal, a logistic regression model was formulated analyzing interactions between landscape attributes and allowing a prediction of cork oak mortality. • Maximum values of MI were found in (i) shrublands and open woodlands with shrub encroachment (MI 6 and 3, respectively), where competition for soil water between tree and understory increases; and (ii) on lower slopes in the rounded hilltops and smooth hillsides or shallow soils where access to groundwater resources during summer drought is diﬃcult. • The model highlighted the importance of the agroforestry systems on cork oak mortality and may be used to identify sensitive areas where mitigation actions should be employed in a scenario of increasing drought severity in these Mediterranean ecosystems.</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%">Bullitta, Simonetta</style></author><author><style face="normal" font="default" size="100%">Dettori, Sandro</style></author><author><style face="normal" font="default" size="100%">Manchinu, Manuela</style></author><author><style face="normal" font="default" size="100%">Filigheddu, Maria Rosaria</style></author><author><style face="normal" font="default" size="100%">Piluzza, Giovanna</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Characterization of Sardinian cork oak (Quercus suber L.) genetic resources for economically important traits</style></title><secondary-title><style face="normal" font="default" size="100%">Genetic Resources and Crop Evolution</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">cluster analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork quality</style></keyword><keyword><style  face="normal" font="default" size="100%">DNA polymorphisms</style></keyword><keyword><style  face="normal" font="default" size="100%">Principal component analysis</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%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2010///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.springerlink.com/index/10.1007/s10722-010-9636-7</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">58</style></volume><pages><style face="normal" font="default" size="100%">1007 - 1020</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Considering the very high socio economic value of cork oak (Quercus suber L.) in Mediterranean areas, a better knowledge of local genetic resources is necessary in order to reach a good balance between the conservation issues and the need of an efﬁcient cork production network. In such frame, local germplasm of Q. suber from the main cork production areas of Sardinia was analysed for DNA and isozyme polymorphisms and for cork quality in relation to some environmental parameters. A total number of 24 sample stands of cork oak were selected, representing typical vegetation, sylvicultural and cork quality features within the eight identiﬁed cork growing areas in Sardinia. Considerable variation was found between cork oak stands of the different areas. Results of the principal component analysis performed on the cork quality data and environmental characters of the eight areas, showed that the ﬁrst three components explain 72.2% of the variation. The major characters involved in this differentiation were cork quality characters such as dimensional recover, moisture and Mg content of the cork and also elevation of stands m a.s.l. for the ﬁrst component. The second component appears to be determined by some climatic parameters (average annual temperature and average of the minimum temperatures of coldest month) and by the Fe and Zn in the cork. For the third component, major characters involved in differentiation are average annual rainfall, bark thickness and Ca content in the cork.</style></abstract><issue><style face="normal" font="default" size="100%">7</style></issue></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, Augusta</style></author><author><style face="normal" font="default" size="100%">Pereira, Helena</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%">Análise Espacial da Mortalidade do Sobreiro em S.

Bartolomeu da Serra (Santiago do Cacém), integrada numa região em que ela ocorre com elevada incidência, através de técnicas de detecção remota (SIG), e determinou-se a probabilidade de ocorrência de mortalidade através da aplicação de um modelo de regressão logística. Determinou-se um índice de mortalidade e identificaram-se as unidades fisiográficas com maior probabilidade de mortalidade em três sistemas agroflorestais distintos: floresta de sobreiro (florestas densas), montado de sobro tradicional (florestas abertas em sistemas dominantemente agrícolas, com culturas arvenses sob coberto) e incultos (florestas abertas em sistemas dominantemente incultos, com matos sob coberto). A mortalidade do sobreiro é significativamente diferente para os três tipos de sistemas agro-florestais. A mortalidade é influenciada por características físicas da paisagem como o solo, o declive e a exposição. Em solos pouco profundos ou em solos mais compactos, a mortalidade é mais frequente, mostrando a importância do desenvolvimento radicular em profundidade do sobreiro em regiões susceptíveis a extensos períodos de secura.</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;periodical: Congresso Florestal Nacional, 6º, Ponta Delgada, 2009 - A floresta num mundo globalizado</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%">Fernandes, Ana</style></author><author><style face="normal" font="default" size="100%">Fernandes, Iva</style></author><author><style face="normal" font="default" size="100%">Cruz, Luís Luís</style></author><author><style face="normal" font="default" size="100%">Mateus, Nuno</style></author><author><style face="normal" font="default" size="100%">Cabral, Miguel</style></author><author><style face="normal" font="default" size="100%">de Freitas, Victor</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Antioxidant and Biological Properties of Bioactive Phenolic Compounds from Quercus suber L.</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Agricultural and Food Chemistry</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">antioxidants</style></keyword><keyword><style  face="normal" font="default" size="100%">Antioxidants: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">Antioxidants: isolation &amp; purification</style></keyword><keyword><style  face="normal" font="default" size="100%">Antioxidants: pharmacology</style></keyword><keyword><style  face="normal" font="default" size="100%">Antitumor activity</style></keyword><keyword><style  face="normal" font="default" size="100%">Cell Line</style></keyword><keyword><style  face="normal" font="default" size="100%">Cell Proliferation</style></keyword><keyword><style  face="normal" font="default" size="100%">Cell Proliferation: drug effects</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork</style></keyword><keyword><style  face="normal" font="default" size="100%">Humans</style></keyword><keyword><style  face="normal" font="default" size="100%">Hydrolyzable Tannins</style></keyword><keyword><style  face="normal" font="default" size="100%">Hydrolyzable Tannins: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">Hydrolyzable Tannins: isolation &amp; purification</style></keyword><keyword><style  face="normal" font="default" size="100%">Hydrolyzable Tannins: pharmacology</style></keyword><keyword><style  face="normal" font="default" size="100%">phenolic compounds</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Extracts</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Extracts: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Extracts: isolation &amp; purification</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Extracts: pharmacology</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber L.</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">Tumor</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.ncbi.nlm.nih.gov/pubmed/19888728http://dx.doi.org/10.1021/jf902093m</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">57</style></volume><pages><style face="normal" font="default" size="100%">11154 - 11160</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Phenolic compounds, namely, hydrolyzable tannins and low molecular weight phenolic compounds, were isolated and purified from Portuguese cork from Quercus suber L. Some of these compounds were studied to evaluate their antioxidant activity, including free-radical scavenging capacity (DPPH method) and reducing capacity (FRAP method). All compounds tested showed significant antioxidant activity, namely, antiradical and reducing properties. The antiradical capacity seemed to increase with the presence of galloyl groups. Regarding the reducing capacity, this structure-activity relationship was not so clear. These compounds were also studied to evaluate the growth inhibitory effect on the estrogen responsive human breast cancer cell line (ERþ) MCF-7 and two other colon cancer cell lines (Caco-2 and HT-29). Generally, all the compounds tested exhibited, after a continuous exposure during a 48 h period, a dose-dependent growth inhibitory effect. Relative inhibitory activity was primarily related to the number of phenolic hydroxyl groups (galloyl and HHDP moieties) found in the active structures, with more groups generally conferring increased effects, except for HHDP-di-galloyl-glucose. Mongolicain B showed a greater potential to inhibit the growth of the three cell lines tested, identical to the effect observed with castalagin. Since these compounds are structurally related with each other, this activity might be based within the C-glycosidic ellagitannin moiety.</style></abstract><issue><style face="normal" font="default" size="100%">23</style></issue><notes><style face="normal" font="default" size="100%">From Duplicate 2 (Antioxidant and Biological Properties of Bioactive Phenolic Compounds from Quercus suber L. - Fernandes, Ana; Fernandes, Iva; Cruz, Luís; Mateus, Nuno; Cabral, Miguel; de Freitas, Victor)From Duplicate 2 (Antioxidant and Biological Properties of Bioactive Phenolic Compounds from Quercus suber L. - Fernandes, Ana; Fernandes, Iva; Cruz, Luís; Mateus, Nuno; Cabral, Miguel; de Freitas, Victor)The following values have no corresponding Zotero field:&lt;br/&gt;publisher: American Chemical Society&lt;br/&gt;accession-num: 19888728</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%">Costa, A.</style></author><author><style face="normal" font="default" size="100%">Oliveira, A.

Speciﬁ- cally, it proposes an hierarchical approach that encompasses the spatial classiﬁcation of a cork oak forest and the temporal scheduling of cork harvests. The use of both geographical information systems and operations research techniques is addressed. Emphasis is on the achievement of cork even ﬂow objectives. Results from an application to a case study in the Charneca Plioce´nica of Ribatejo in southern Portugal encompassing a cork oak forest extending over 4.8 thousand ha are discussed. They suggest that the proposed approach is capable of effective spatial classiﬁcation of cork oak management units. They further suggest that it may be used to select optimal cork even ﬂow scheduling strategies. Results also show that the proposed approach may lead to a substantial increase in net present value when compared to traditional approaches to cork oak forest management planning.</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%">Coquet, Corinne</style></author><author><style face="normal" font="default" size="100%">Ferré, Elisée</style></author><author><style face="normal" font="default" size="100%">Peyronel, Dominique</style></author><author><style face="normal" font="default" size="100%">Dal Farra, Claude</style></author><author><style face="normal" font="default" size="100%">Farnet, Anne Marie</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Identification of new molecules extracted from Quercus suber L. cork.</style></title><secondary-title><style face="normal" font="default" size="100%">Comptes rendus biologies</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">2.6-heptanediol</style></keyword><keyword><style  face="normal" font="default" size="100%">3-friedelanol</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber L.</style></keyword><keyword><style  face="normal" font="default" size="100%">suberin</style></keyword><keyword><style  face="normal" font="default" size="100%">Terpens</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2008</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2008///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/18940700</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">331</style></volume><pages><style face="normal" font="default" size="100%">853 - 858</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Various methods of suberin extraction have been used in order to identify monomers of this complex polymer.

Moreover, the wax chemical composition found here varied from previous results since cerin was not identified while friedelin and betulin were. Three fractions were obtained: a polymeric, a monomeric and a low molecular weight fraction, the last of which has never before been described. 2,6-heptanediol was found to be the main compound of this fraction.

No down-regulation of photosynthesis was found after six months of growth under elevated CO2. Photosynthetic rates at 15°C or 35°C were also higher in elevated than in ambient C02-grown plants, when measured at their respective CO2 growth condition. Stomata of elevated C02-grown plants were less responsive to temperature as compared to ambient CO2 plants. The after effect of a heat-shock treatment (4 h at 45°C in a chamber with 80% of relative humidity and 800—1000 tmol rn2 photon flux density) on Amax was less in elevated than in ambient C02-grown plants. At the photochemical level, the negative effect of the heat-shock treatment was slightly more pronounced in ambient than in elevated CO2-grown plants. A greater tolerance to oxidative stress caused by high temperatures in elevated C02-grown plants, in comparison to ambient CO2 plants, is suggested by the increase in superoxide dismutase activity, after 1 h at 45°C, as well as its relatively high activity after 2 and 4 h of the heat shock in the elevated C02-grown plants in contrast with the decrease to residual levels of superoxide dismutase activity in ambient C02-grown plants immediately after 1 h at 45°C. The observed increase in catalase after 1 h at 45°C in both ambient and elevated C02-grown plants, can be ascribed to the higher rates of photorespiration and respiration under this high temperature.</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%">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 same fungus also produces several metabolites such as the diplopyrone, the (3S,4R)-trans- and the (3R,4R)-cis-4-hydroxymellein, the sapinofuranone B and its (S,S)-enantiomer, the well known sphaeropsidins A-C, and the diplobifuranylones A and B. 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. Diplofuranone A tested at 0.2 mg mL-1 on non-host plant did not show phytotoxic activity.</style></abstract><issue><style face="normal" font="default" size="100%">vii</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%">Arbouche, Halima Saadia</style></author><author><style face="normal" font="default" size="100%">Arbouche, Fodil</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Evaluation of the energy value of plant species consumed by the Barbary Deer (Cervus elaphus barbarus, Bennet 1833) in the area of El Ayoune (El Kala National Park, Algeria)</style></title><secondary-title><style face="normal" font="default" size="100%">REVUE D ECOLOGIE-LA TERRE ET LA VIE</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">grazed plant species</style></keyword><keyword><style  face="normal" font="default" size="100%">herbaceous</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus ilex.L</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%">62</style></volume><pages><style face="normal" font="default" size="100%">375 - 380</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Plant species taken for food by the Barbary Deer were determined by direct observation during one year.

Results show that the more energy-giving elements are plants from the herbaceous layer and the acorns of Cork Oak (Quercus suber). From the shrubby layer, the Strawberry-tree (Arbustus unedo) comes first with an energy value comparable to that of green grass fodder, followed by Tree Heath (Erica arborea), Lentisc (Pistacia lentiscus) and Filaria (Phillyrea augustifolia) with energy values comparable to those of grass hays. The energy values of the other shrubby plant species are comparable with those of cereal straws; they do not ensure but the needs for maintenance.</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><notes><style face="normal" font="default" size="100%">Key W: ASKey W: ASThe following values have no corresponding Zotero field:&lt;br/&gt;pub-location: 57 RUE CUVIER, 75005 PARIS 5, FRANCE&lt;br/&gt;publisher: SOC NATL PROTECTION NATURE ACCLIMATATION FRANCE</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%">Bento, M.

In Quercus suber, suberin is the most important structural component of cork cell walls. Studies have shown that suberin is made up mostly of hydroxycarboxylic acids and that it is endowed with many special mechanical and chemical properties that evoke a possible smoothing effect on the surface of the skin. Therefore, we were interested in investigating the effect of this cork extract on the skin's surface in a double-blind clinical study. The study was conducted in 15 healthy volunteers, aged 22 to 52 years. The volunteers applied a gel formula with 3% of cork extract, or placebo gel, on each forearm. Skin surface roughness was evaluated visually by pictures and by silicone replicas 1 and 2 h after application, followed by statistical analysis using the matched-pairs McNemar statistical test. McNemar analysis of the pictures revealed that application of cork extract on the skin resulted in a highly significant reduction of roughness 1 h after application. This effect was observed in 73.3% of volunteers. Two hours after cork extract application, a highly significant improvement of skin roughness was found in 78.6% of volunteers. Moreover, silicone replica treatment confirmed significant improvement in average of roughness at 2 h. These results demonstrate that cork extract provides a remarkable and highly significant tensor and smoothing effect on the skin, which could be of great use in anti-aging skin care products.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><notes><style face="normal" font="default" size="100%">Journal Article,Randomized Controlled Trial,Journal Article,Randomized Controlled Trial,The following values have no corresponding Zotero field:&lt;br/&gt;pub-location: Vincience Research Center, Sophia Antipolis, France.</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, M.

Thermal imaging may provide a rapid method for monitoring the extent of stress. The ecophysiology of cork trees was studied over three years. Three treatments were applied by means of rainfall capture and irrigation, with plots receiving 120%, 100%, or 80% of natural precipitation. Despite stomatal closure, detected using both thermal imaging and porometry, leaf water potential fell during the summer, most drastically during the third year of accumulative stress. The quantum efficiency (ΦPSII) and the maximum efficiency Formula of photosystem II also fell more intensely over the third summer, while non-photochemical quenching (NPQ) increased. The reduced precipitation treatment sporadically further reduced leaf water potential, stomatal conductance (gs), IG (an index of gs derived from thermal imaging), ΦPSII, and Formula, and increased leaf temperature and NPQ. It is concluded that these are very resilient trees since they were only severely affected in the third year of severe drought (the third year registering 45% less rainfall than average), and removing 20% of rainfall had a limited impact.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><notes><style face="normal" font="default" size="100%">Key words: ASKey words: ASThe following values have no corresponding Zotero field:&lt;br/&gt;pub-location: TIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY&lt;br/&gt;publisher: SPRINGER HEIDELBERG</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, María a</style></author><author><style face="normal" font="default" size="100%">Gomez, Arancha</style></author><author><style face="normal" font="default" size="100%">Sepulveda, Federico</style></author><author><style face="normal" font="default" size="100%">Seguí, José M.</style></author><author><style face="normal" font="default" size="100%">Testillano, Pilar S.</style></author><author><style face="normal" font="default" size="100%">Manzanera, Jose a</style></author><author><style face="normal" font="default" size="100%">Risueño, Maria-Carmen</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Microspore-derived embryos from Quercus suber anthers mimic zygotic embryos and maintain haploidy in long-term anther culture.</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of plant physiology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cytochemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">DNA-Analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">flow cytometry</style></keyword><keyword><style  face="normal" font="default" size="100%">haploid embryos</style></keyword><keyword><style  face="normal" font="default" size="100%">immunocyto- chemistry</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%">2003</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2003///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/12964871</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">160</style></volume><pages><style face="normal" font="default" size="100%">953 - 960</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Microspore-derived embryos produced from cork oak anther cultures after long-term incubations (up to 10-12 months) were analysed in order to determine the genetic variability and ploidy level stability, as well as morphology, developmental pattern and cellular organisation. Most of the embryos from long-term anther cultures were haploid (90.7%), corresponding to their microspore origin. The presence of a low percentage of diploid embryos (7.4%) was observed. Microsatellite analysis of haploid embryos, indicated different microspores origins of the same anther. In the diploid embryos, homozygosity for different alleles was detected from anther wall tissues, excluding the possibility of clonal origin. The maintenance of a high proportion of haploid embryos, in long-term anther cultures, is similar in percentage to that reported in embryos originating after 20 days of plating (Bueno et al. 1997). This suggests that no significant alterations in the ploidy level occurred during long incubations (up to 12 months). These results suggest that ploidy changes are rare in this in vitro system, and do not significantly increase during long-term cultures. Microscopical studies of the microspore embryos in various stages revealed a healthy and well developed anatomy with no aberrant or chimeric structures. The general morphology of embryos appearing at different times after plating, looked similar to that of earlier embryos, as well as the zygotic embryos, indicating that they represent high quality material for cork oak breeding.</style></abstract><issue><style face="normal" font="default" size="100%">8</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;accession-num: 12964871</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 Freitas, Maria Isabel Carrasquinho</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Propagação Vegetativa de Sobreiros Seleccionados</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%">Bud grafting</style></keyword><keyword><style  face="normal" font="default" size="100%">Clones</style></keyword><keyword><style  face="normal" font="default" size="100%">Cuttings</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber L.</style></keyword><keyword><style  face="normal" font="default" size="100%">vegetative propagation</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2002</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2002///</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">10</style></volume><pages><style face="normal" font="default" size="100%">17 - 52</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=S0870-63522002000100002&amp;nrm=iso</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The aim of this investigation was to evaluate the possibilities of vegetative propagation techniques of adult cork oak trees so as to develop an approach applicable to a genetic improvement breeding program. Bud grafting and cuttings were used to multiply and mass propagate selected cork oak trees. Forty-six cork oak trees were reproduced from clone banks. September proved to be a better season for grafting than June/July. Rooting season and the temperature of the rooting substrate were demonstrated to be important factors in juvenile cuttings response. The highest rooting ability was achieved in August with a rooting substrate temperature of 28°C (57.0%). The best rooting rate was obtained by maintaining cuttings in rooting media for four months. The application of IBA influenced rooting ability both in cuttings from seedlings and those from the clone bank. Nevertheless, juvenile material needed a lower IBA concentration (0.5%) than the older material (1%). The clone and age of grafting were shown to influence the rooting ability. The decrease of rooting ability with age of grafting requires a dynamic management of the clone bank. The vegetative propagation of selected adult cork oak trees seems to be a viable technique, establishing a prior clone bank, by means of grafting, and then mass propagation through cuttings of this material.</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%">Costa, A.</style></author><author><style face="normal" font="default" size="100%">Pereira, H.</style></author><author><style face="normal" font="default" size="100%">Oliveira, A.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">A dendroclimatological approach to diameter growth in adult cork-oak trees under production</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%">climatic fluctuations</style></keyword><keyword><style  face="normal" font="default" size="100%">dendroclimatology</style></keyword><keyword><style  face="normal" font="default" size="100%">diameter growth</style></keyword><keyword><style  face="normal" font="default" size="100%">Mediterranean climate</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%">2001</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2001///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.springerlink.com/index/10.1007/s004680100119</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">15</style></volume><pages><style face="normal" font="default" size="100%">438 - 443</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The diameter growth of mature cork oaks under cork production in southwestern Portugal was studied during a 9-year cork-production cycle in relation to fluctuations in precipitation and temperature, and to drought indices combining the two variables.

The rheological behaviour of the suberin oligomers as well as of the inks, with and without suberin, were investigated as a function of temperature. It was shown that the addition of suberin induces a decrease of viscosity of both inks. The tack of pristine inks, suberin oligomers and their mixtures were determined at different temperatures: the variation of this parameter as a function of time provided information about the drying kinetics of these formulations. The tack of the ‘Waterless’ ink was found to increase with the introduction of suberin, whereas that of vegetable-oil based counterparts decreased. All the trends observed were interpreted in terms of the differences in composition between the two types of inks.

This crisis is caused by both human exploitation and overgrazing by animals. This situation is also affected by the existence of harmful insects and parasitic fungi. One of the most common species is Diplodia mutila Fr. apud Mont. (group of Coelomycetes) anamorph of Botryosphaeria stevensii Shoem., which causes withering and cankers on trunks and branches. The electron microscope observations on pycnosporogenesis and the study of the relation plant-host-pathogen show the structure and the biological cycle of Diplodia mutila, the endophytic and the systemic development of the pathogen and the irreversible damage on the plant host.

The method is based on previously reported work that exploits different proton relaxation properties for different domains of an heterogeneous system. However, unlike the original method that obtained subspectra through a trial-and-error approach, the method here presented solves the problem mathematically, thus avoiding the time-consuming and non-rigorous trial-and-error step. The method is applied to mixtures of three and four polymers and to a more complex system: cork cell walls. As expected, as the number of components increases, the sharing of relaxation properties between different components is increasingly probable, either due to incidental coincidence of relaxation times or to specific interactions and intimate mixing of compounds. While this hinders the calculation of the subspectra of single chemical components, it may provide useful information about inter-component interactions. This possibility was demonstrated by the application of this method to cork cell walls. Both three-component and four-component approaches showed that three domains exist in cork cell walls: carbohydrate/lignin matrix, mobile suberin close to (probably bonded to) lignin groups (about 42% w/w) and hindered suberin close to (probably bonded to) carbohydrate-OCH2O groups (about 4% w/w).</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;accession-num: 10868562</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%">Cordeiro, N.</style></author><author><style face="normal" font="default" size="100%">Belgacem, M.

Two fractions were systematically isolated, namely (i) methylene-chloride soluble products, which corresponded to linear and branched macromolecules and (ii) methylene-chloride insoluble products, representing the crosslinked material. The structures of these polymers were regular and no appreciable side reactions were detected. DSC analyses provided information about the glass transition temperature of both fractions and this parameter was correlated with the stiffness of the isocyanate used. The TGA of these polyurethanes showed that they started to degrade at about 175 degrees C and that the residue at 400 degrees C was around 50%. The highest amounts of insoluble fractions, as well as the highest T-g,s, were reached when an initial \{[\}NCO]/\{[\}OH] of unity was used. (C) 1999 Elsevier Science B.V.

After derivatization, the main components of the volatile fraction, representing less than half of the total, were found to be omega-hydroxymonocarboxylates, alpha, omega-dicarboxylates, simple alkanoates and 1-alkanols, all with chain lengths ranging from C16 to C24. A second fraction, with an average molecular weight about three times higher, was detected by VPO, MS and GPC. The presence of this important fraction in cork suberin had not been recognized in earlier studies.

The cork-ring width chronologies of the three peel-off samplings show definite agreement patterns. Differences in ring width in years of greater and lesser growth are clearly marked. Correlation between ring width and rainfall indicates that the rain periods with the greatest influence on cork growth are those occurring from November to June, followed by those from November to September. Temperature, on the other hand, shows a negative correlation with cork growth, except during the coldest months and the months of April and September when temperature possibly has a crucial influence on phellogen activation.</style></abstract><issue><style face="normal" font="default" size="100%">I 996</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%">FARIA, T.</style></author><author><style face="normal" font="default" size="100%">Wilkins, D.</style></author><author><style face="normal" font="default" size="100%">Besford, R.

Plants grown in elevated CO2 (700 ppm) showed a down-regulation of photosynthesis and had lower amounts and activity of Rubisco than plants grown at ambient CO2 (350 ppm), after 14 months in the greenhouse. At that time plants were subjected to a heat-shock treatment (4 h at 45°C in a chamber with 80% relative humidity and 800–1000 µmol m−2 s−1 photon flux density). Growth in a CO2-enriched atmosphere seems to protect cork oak leaves from the short-term effects of high temperature. Elevated CO2 plants had positive net carbon uptake rates during the heat shock treatment whereas plants grown at ambient CO2 showed negative rates. Moreover, recovery was faster in high CO2-grown plants which, after 30 min at 25°C, exhibited higher net carbon uptake rates and lower decreases in photosynthetic capacity (Amax as well as in the efficiency of excitation energy captured by open photosystem II reaction centres (FvJFm than plants grown at ambient CO2. The stomata of elevated CO2 plants were also less responsive when exposed to high temperature.</style></abstract><issue><style face="normal" font="default" size="100%">11</style></issue><notes><style face="normal" font="default" size="100%">10.1093/jxb/47.11.175510.1093/jxb/47.11.1755</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%">Fos, S.</style></author><author><style face="normal" font="default" size="100%">Barreno, E.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Crecimiento radial del corcho de reproducción de los alcornocales catalanes y valencianos</style></title><secondary-title><style face="normal" font="default" size="100%">Scientia gerundensis</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Anatomy</style></keyword><keyword><style  face="normal" font="default" size="100%">bioclimatology</style></keyword><keyword><style  face="normal" font="default" size="100%">cork-oak</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber L.</style></keyword><keyword><style  face="normal" font="default" size="100%">Radial growth</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1994</style></year><pub-dates><date><style  face="normal" font="default" size="100%">1994///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.researchgate.net/publication/39097545_Crecimiento_radial_del_corcho_de_reproduccin_en_los_alcornocales_catalanes_y_valencianos/file/9fcfd50ed25b6ac46c.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">20</style></volume><pages><style face="normal" font="default" size="100%">5 - 15</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Eastern cork-oak forests are present in territories with different environmental characteristics, allowing to raise comparative studies between them. This work is an attempt to evaluate the radial growt differences of the reproduction cork, using tschniques of optical microscopy, having developed a new methodology. Thus, severa1 sites from catalonian and valencian cork-oak forests have been selected. In the quantification of this growth, the contribution of each cork type (early cork and late cork) in the annual growing rings have been differentia- ted. The annual increments measwed in catalonian corks have an average of 2.958 mm, being a bit lower in Castell6n with 1.622 mm. These differences in the annual growing rings are due to the early development higher in catalonian cork (2.623 mm) than in valencian ones (1.235 mm), late cork thickness is similar in the two areas. These differences seem to be related with the escarce summer dry period in catalonian cork-oak forests. Important anato- mical differences related with the mentioned ombroclimatic asimetries have been observed too.</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%">Caritat, A.</style></author><author><style face="normal" font="default" size="100%">Molinas, M.</style></author><author><style face="normal" font="default" size="100%">Oliva, M.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">El crecimiento radial del alcornoque en cinco parcelas de alcornocal de Girona</style></title><secondary-title><style face="normal" font="default" size="100%">Scientia gerundensis</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%">Mediterranean sclerophylls</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber L.</style></keyword><keyword><style  face="normal" font="default" size="100%">Radial growth</style></keyword><keyword><style  face="normal" font="default" size="100%">wood rings</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1992</style></year><pub-dates><date><style  face="normal" font="default" size="100%">1992///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://dugi-doc.udg.edu/handle/10256/5328</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">18</style></volume><pages><style face="normal" font="default" size="100%">73 - 83</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Tree rings of Quercus suber L. are porous and difficult to read because of the irregular growth rhythm. Radial growth has been measured in five experimental plots situated in the region of Girona (Catalonia, NE Spain). Cores of ten standard trees of each plot were extracted using a Pressler borer. In three plots woody disks from standard trees were also obtained. Tree rings were examinated under binocularlens. The CATRAS computer program (Anio1,1983 ) was used to find statistical parameters. Tree rings have an average width changing from 1,21 to 3,74 mm, while average standard deviation varies from 0,24 to 1,88 mm. and autocorrelation from 0,008 to 0.894 . These values are similar to those found in other Mediterranean Quercus, like Q. ilex L. The studied cork-oak plots ,with diametrical classes between 5 and 57 cm, show regular growth characteristic of young forest. The St. Hilari plot has the maturest trees, (diametrical classes from 24 to 57 cm) and this fact was reflectedin thegrowthcurve. Suddengrowthincreases are attributed to forestry management measures like clearing or selective cutting down. The effects of periodic cork extractions could no be clearly appreciated in this study.</style></abstract></record></records></xml>
