We sampled vegetation and collected environmental data in 81 10 m × 10 m plots in five zones representing the largest Q. ilex woodlands throughout the study area, analysing them within an a priori hypothesis framework with the use of Path Analysis. Changes in plant diversity were mainly influenced by environmental factors related to precipitation and temperature regimes, as well as by total plant cover. In particular, changes in species composition were determined by factors associated with the temperature regime through their influence on both woody and annual herbaceous plant richness, and by factors related to the precipitation regime through their influence on perennial herbaceous plant richness, likely due to the differential tolerances of these functional groups to cold and water stress. Our results emphasize the importance of differences in environmental adaptability of the most important life-forms with regard to explaining compositional change (beta diversity) along aridity gradients, and the mediator role of total plant cover in relation to the effects of soil conditions on plant diversity.</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%">Leal, Ana I.</style></author><author><style face="normal" font="default" size="100%">Martins, Ricardo C.</style></author><author><style face="normal" font="default" size="100%">Palmeirim, Jorge M.</style></author><author><style face="normal" font="default" size="100%">Granadeiro, José P.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Influence of habitat fragments on bird assemblages in Cork Oak woodlands</style></title><secondary-title><style face="normal" font="default" size="100%">Bird Study</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">cork oak woodlands</style></keyword><keyword><style  face="normal" font="default" size="100%">fragments</style></keyword><keyword><style  face="normal" font="default" size="100%">matrix (voyant)</style></keyword><keyword><style  face="normal" font="default" size="100%">riparian galleries</style></keyword><keyword><style  face="normal" font="default" size="100%">Species composition</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://dx.doi.org/10.1080/00063657.2011.576235</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">58</style></volume><pages><style face="normal" font="default" size="100%">309 - 320</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Capsule Fragments of olive groves and riparian galleries have a positive influence on bird assemblages in Cork Oak woodlands. Aims Assess the impact of fragments of olive groves and riparian vegetation on the birds of the matrix of Cork Oak woodland. Methods Bird point counts at increasing distances (0, 50, 150, 250 and 350 m) from 15 olive groves and 13 sectors of riparian vegetation embedded in a matrix of Cork Oak woodland to determine species assemblages and species abundance. Results A total of 72 bird species were recorded during the spring, and 61 in winter. The diversity of the bird assemblages of the Cork Oak matrix was somewhat greater near fragments. The density of six out of the 17 most abundant bird species varied due to the presence of olive groves or riparian vegetation. Of those, five were more abundant near the fragments and only one was less abundant. These effects could be mostly predicted from the species' density in the fragments of olive groves and riparian vegetation and depended on the season. Conclusions In Mediterranean landscapes dominated by Cork Oak woodlands, the maintenance of the existing networks of olive grove fragments and riparian galleries has a positive effect on the bird assemblages of the woodland matrix. The increase in abundance of birds near olive groves and riparian galleries is probably due to the additional fruit resources provided by the fragments, especially in winter. We conclude that active maintenance of the existing fragments should be included in the management of this valuable agricultural?silvicultural?pastoral system.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><notes><style face="normal" font="default" size="100%">doi: 10.1080/00063657.2011.576235doi: 10.1080/00063657.2011.576235The 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%">Lloret, F.</style></author><author><style face="normal" font="default" size="100%">Solé, A.</style></author><author><style face="normal" font="default" size="100%">Pino, J.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Patterns of species impoverishment in managed forests of Catalonia (NE Spain)</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Vegetation Science</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">diversity</style></keyword><keyword><style  face="normal" font="default" size="100%">Forest management</style></keyword><keyword><style  face="normal" font="default" size="100%">nestedness</style></keyword><keyword><style  face="normal" font="default" size="100%">Species composition</style></keyword><keyword><style  face="normal" font="default" size="100%">Species richness</style></keyword><keyword><style  face="normal" font="default" size="100%">succession</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://onlinelibrary.wiley.com/doi/10.1111/j.1654-1103.2009.01059.x/full</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">20</style></volume><pages><style face="normal" font="default" size="100%">675 - 685</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Question: In managed forests, woody plant richness shows great variations in pattern. Herein we try to elucidate the role of major factors, such as successional status, to explain this variation. Assuming that less competitive or disturbance-sensitive species will be systematically more prone to disappear, we investigate the existence of nonrandom patterns of species impoverishment – i.e., the number of species unable to attain maximal richness – and the ecological and successional status of species associated with impoverishment in relation to a regional climatic gradient. Methods: We explored species composition in approximately 7500 forest plots in Catalonia (NE Spain). We evaluated non-random patterns of species impoverishment by analyzing their nestedness. Multivariate analysis was used to relate environmental variables and impoverishment to species occurrence. Plot successional status and ecological range were also estimated from species composition, and species impoverishment was then correlated to these estimators. Results: Most forests show a non-random pattern of species loss: poor stands tend to retain the same species, and the species determining high richness tend to be the same. Late successional species tend to be more common in impoverished plots of drier and warmer forests, while species typical of open or disturbed habitats are more common in impoverished plots of moister and colder forests. Communities dominated by early or late successional species are mostly impoverished, while the richest stands are constituted by species of intermediate stages. Forests dominated by species with a narrow or wide ecological range showed high impoverishment levels, while the richest stands had species with an intermediate ecological range. Discussion: In warmer Mediterranean forests, impoverishment tends to be associated with late successional stages, while in moister and colder forests, species loss is more closely related to disturbance and exploitation. This study reveals the difﬁculties involved in using species richness as a simple descriptor of the degree of forest conservation. Identiﬁcation of dominant species and species indicative of ecological processes would constitute an easily applicable practice that would consolidate assessment of forests status.</style></abstract></record></records></xml>
