For direct-seeded plants, seed mass was found to have a significantly positive effect on the establishment success in both species. No clear-cut trend in survival was detected in the 3- year-old seedlings. The survival of the 3-year-old Q. suber seedlings and the direct-seeded plants was similar, but not in Q. ilex, where the survival of the 3-year-old seedlings was the lowest. The latter result may have been a consequence of cultivation in smaller containers leading to root deformation and limiting plant access to water. Differences in survival could not be ascribed to morphological and growth variables or stomatal conductance. &amp; Conclusion Based on the results, all three artificial regeneration methods can be similarly effective provided appropriate nursery cultivation conditions are used and seeds are protected against predators, the best choice in each case being dictated by the particular restoration goals.</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%">Hernando, Ana</style></author><author><style face="normal" font="default" size="100%">Tejera, Rosario</style></author><author><style face="normal" font="default" size="100%">Velazquez, Javier</style></author><author><style face="normal" font="default" size="100%">Núñez, María Victoria</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Quantitatively defining the conservation status of Natura 2000 forest habitats and improving management options for enhancing biodiversity</style></title><secondary-title><style face="normal" font="default" size="100%">Biodiversity and Conservation</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Adaptive management</style></keyword><keyword><style  face="normal" font="default" size="100%">Asexual regeneration</style></keyword><keyword><style  face="normal" font="default" size="100%">Cattle</style></keyword><keyword><style  face="normal" font="default" size="100%">Coppice forest</style></keyword><keyword><style  face="normal" font="default" size="100%">GIS</style></keyword><keyword><style  face="normal" font="default" size="100%">Mediterranean biogeographic region</style></keyword><keyword><style  face="normal" font="default" size="100%">oak</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus pyrenaica</style></keyword><keyword><style  face="normal" font="default" size="100%">Spain</style></keyword><keyword><style  face="normal" font="default" size="100%">Stand</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://link.springer.com/10.1007/s10531-010-9835-8http://www.springerlink.com/index/10.1007/s10531-010-9835-8</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">19</style></volume><pages><style face="normal" font="default" size="100%">2221 - 2233</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The main goal of Natura 2000 network is to guarantee the favourable conservation status of habitats and species ensuring European biodiversity. As a result, certain forest areas have been included in this network listed as 9230-Quercus pyrenaica habitat and 9340-Quercus ilex subsp. rotundifolia forest habitat. These areas were previously used for ﬁrewood extraction or livestock grazing and browsing. Nowadays these habitats are coppice forests with asexual regeneration, which is far from the desired conservation status. Traditional timber harvesting plans do not take account of the new objectives required for these Natura sites, which attempt to ensure biodiversity and recreational uses instead of simply focusing on timber production. This paper proposes a ﬂexible methodology (applied to the study area ‘‘Dehesa Boyal’’ in A´ vila, Spain) for managing Natura 2000 forest sites by stands for sustainable forest management and the new requirements. The methodology has two phases. The ﬁrst, ‘‘Division of the forest area into stands’’, deﬁnes homogeneous patches of vegetation distinct in species composition, physiognomic structure and future management. The second, ‘‘Conservation status assessment of stands’’, quantiﬁes the conservation status of each previously classiﬁed stand considering a series of factors such as: functional health, restoration, ﬂoral richness and structure. A total value integrating the conservation status of stands is then calculated for the habitat. Both phases use Geographic Information System tools for managing information and visualizing results. The proposed methodology provides forest managers with a good knowledge of the territory and subsequently enables them to take appropriate conservation measures to maintain biodiversity.</style></abstract><issue><style face="normal" font="default" size="100%">8</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%">Delhon, Claire</style></author><author><style face="normal" font="default" size="100%">Thiébault, Stéphanie</style></author><author><style face="normal" font="default" size="100%">Berger, Jean-François</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Environment and landscape management during the Middle Neolithic in Southern France: Evidence for agro-sylvo-pastoral systems in the Middle Rhone Valley</style></title><secondary-title><style face="normal" font="default" size="100%">Quaternary International</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">CHARCOAL ANALYSIS</style></keyword><keyword><style  face="normal" font="default" size="100%">Middle Neolithic</style></keyword><keyword><style  face="normal" font="default" size="100%">Middle Rhone</style></keyword><keyword><style  face="normal" font="default" size="100%">oak</style></keyword><keyword><style  face="normal" font="default" size="100%">vegetation dynamics (citation)</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://linkinghub.elsevier.com/retrieve/pii/S1040618208001262</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">200</style></volume><pages><style face="normal" font="default" size="100%">50 - 65</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Rescue excavations in the Middle Rhone Valley have provided opportunities to develop innovative strategies for the study of palaeoenvironments. These strategies involve sampling and analysis of botanical remains, recovered not only from archaeological sites but also in ‘‘off-site’’ pedosedimentary sequences thought to be poor in botanical remains. Thus, these remains (phytoliths, pedocharcoal) give access to unexplored depositional contexts, such as alluvial plains. Moreover, off-site data are useful because they minimise the hazard of cultural bias (e.g., selection of species during wood gathering). Comparison of data collected in the alluvial plain with data obtained via anthracological analyses of karstic caves and rock-shelters in the hinterland suggests a complex agro-sylvopastoral management of the landscape during the Middle Neolithic. We propose a pattern that supposes considerable specialization in use of plains vs. slopes in the landscape, and a strong and continuous human pressure on the vegetation and soils between 4500 and 3500 cal BC. Nevertheless, these constraints are not sufﬁcient to explain the persistence of such a system for more than a millennium. Favourable climatic conditions are thought to have been a determining factor in the persistence of an ecologically meta-stable relationship between human societies and their natural environment.</style></abstract><issue><style face="normal" font="default" size="100%">1-2</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%">Gil, L.</style></author><author><style face="normal" font="default" size="100%">Pereira, C.</style></author><author><style face="normal" font="default" size="100%">Branco, P.</style></author><author><style face="normal" font="default" size="100%">Teixeira, A.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Formation of Acutissimin A in red wine through the contact with cork</style></title><secondary-title><style face="normal" font="default" size="100%">JOURNAL INTERNATIONAL DES SCIENCES DE LA VIGNE ET DU VIN</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">acutissimin A</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork</style></keyword><keyword><style  face="normal" font="default" size="100%">HPLC/MS</style></keyword><keyword><style  face="normal" font="default" size="100%">identification</style></keyword><keyword><style  face="normal" font="default" size="100%">oak</style></keyword><keyword><style  face="normal" font="default" size="100%">wine</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><volume><style face="normal" font="default" size="100%">40</style></volume><pages><style face="normal" font="default" size="100%">217 - 221</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">This study shows that when cork material gets in contact with wine, the elagitannins which exist in the cork material (namely one called vescalagin) react with the catechins present in the wine, producing, among others, Acutissimin A, which is an anti-tumoural agent about 250 times more potent than one of the most common anti-cancer drugs clinically used (VP-16). So, the contact of wine samples without the barrel winemaking stage (oak contact) was carried out with cork in order to determine the presence of Acutissimin A. After a contact time of about 30 min, 150 min and 6 days, Acutissimin A was detected in all samples containing cork. In the samples in which the contact was with oak wood, in our conditions, it was not possible to detect Acutissimin A.</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;pub-location: 42 RUE MARSAN, 33300 BORDEAUX, FRANCE&lt;br/&gt;publisher: VIGNE ET VIN PUBLICATIONS INT</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%">Bernardinelli, I.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Potential host plants of Corythucha arcuata (Het., Tingidae) in Europe: a laboratory study</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Applied Entomology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">development time</style></keyword><keyword><style  face="normal" font="default" size="100%">exotic pest</style></keyword><keyword><style  face="normal" font="default" size="100%">laboratory assay</style></keyword><keyword><style  face="normal" font="default" size="100%">northern Italy</style></keyword><keyword><style  face="normal" font="default" size="100%">oak</style></keyword><keyword><style  face="normal" font="default" size="100%">oak lace bug</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://dx.doi.org/10.1111/j.1439-0418.2006.01098.x</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">130</style></volume><pages><style face="normal" font="default" size="100%">480 - 484</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Abstract: The oak lace bug Corythucha arcuata (Say) (Het., Tingidae), native to North America, was found in Europe on Quercus robur L. and other oaks in the spring of 2000. The potential host plant range of this species in Europe and its development time were investigated in a laboratory study. An assay was performed on leaf cuts of different plant species. On the deciduous European oaks (Q. robur, Quercus pubescens Willd, Quercus petraea (Mattuschka) Liebl., Quercus cerris L.), as well as Rubus ulmifolius Schott. and Rubus idaeus L., most of the lace bugs (&gt;50%) reached the adult stage; on Castanea sativa Mill., Rubus caesius L. and Rosa canina L., a reduced number of individuals (&lt;25%) reached the adult stage. No nymphs survived on Quercus rubra L. (mentioned in literature as a host plant), on the evergreen oaks Quercus suber L. and Quercus ilex L., on Malus domestica Borkh. and four tested maple species. On plant species where the lace bug reached the adult stage, the development time varied from 13 to 27 days. On European deciduous oak species, the development time was longer on leaves taken in late summer (September) than on those of late spring (June); on the contrary, such differences were not observed on Rubus species, and Castanea sativa.</style></abstract><issue><style face="normal" font="default" size="100%">9-10</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%">Arena, C.</style></author><author><style face="normal" font="default" size="100%">Vitale, L.</style></author><author><style face="normal" font="default" size="100%">Santo, A.

At C800 both C and CG plants showed a significant increase of net photosynthetic rate (PN) and electron transport rate (ETR) in response to PPFD increase as compared to C390. In addition, at C800 lower non-photochemical quenching (NPQ) values were observed. The differences between C390 and C800 were related to PPFD. The higher PN and ETR and the lower dissipative processes found in CG plants at both CO2 concentrations as compared to C plants suggest that substrate influences significantly photosynthetic response of Q. ilex plants.

Previous data indicate that wood mouse abundance is much higher in small stands. Tree size, frequency of acorn-bearing oaks and acorn abundance were similar in the two sizes of forest stands. Overall acorn consumption was 33.7 times higher in the small stands compared to that in the large stands in 1991, and 3.1 times larger in 1994. Consumption of acorns by mice in the small stands was 49 and 95 times greater than that by birds in the first and second year, respectively. Seedling recruitment was significantly higher in the large stands in both study seasons. Regeneration by ramets was roughly similar in small and large stands in both seasons. Thus, predation by mice was apparently responsible for the failure of sexual reproduction in the small stands. The results suggest that vegetative regeneration might be the prevalent reproductive method of Holm Oaks in small forest tracts.</style></abstract><issue><style face="normal" font="default" size="100%">97</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%">JOFFRE, R.</style></author><author><style face="normal" font="default" size="100%">LACAZE, B.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Estimating tree density in oak savanna-like lsquo;dehesa’ of southern Spain from SPOT data</style></title><secondary-title><style face="normal" font="default" size="100%">International Journal of Remote Sensing</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Dehesa</style></keyword><keyword><style  face="normal" font="default" size="100%">oak</style></keyword><keyword><style  face="normal" font="default" size="100%">savanna-like</style></keyword><keyword><style  face="normal" font="default" size="100%">SOPT data</style></keyword><keyword><style  face="normal" font="default" size="100%">southern Spain</style></keyword><keyword><style  face="normal" font="default" size="100%">tree density</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1993</style></year><pub-dates><date><style  face="normal" font="default" size="100%">1993///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://dx.doi.org/10.1080/01431169308904368</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">14</style></volume><pages><style face="normal" font="default" size="100%">685 - 697</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Abstract The main objective of this study was to establish a method of estimating tree density in savanna-like vegetation systems using the highest spatial resolution available from satellite data (SPOT-1 panchromatic = 10 m resolution) based on the assumption that for sparse trees on a contrasting herbaceous background, spatial filters may provide a direct mapping of tree cover. The study was performed in the ?dehesas? oak-woodland of southern Spain. This particular landscape is characterized by the presence of scattered evergreen oak trees (Quercus ilex and Q. suber) whose density ranges from 0 to 80 even-aged mature trees per hectare which gives the appearance of a savanna-like vegetation. Tree density can be accurately estimated by SPOT-1 panchromatic data after numerical filtering. This method allows the mapping of tree density of the dehesas, a key parameter reflecting the functional vegetation-soil-climate equilibrium which exists for both woody and herbaceous strata.</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><notes><style face="normal" font="default" size="100%">doi: 10.1080/01431169308904368doi: 10.1080/01431169308904368The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Taylor &amp; Francis</style></notes></record></records></xml>
