Whilst dehesa forest sustainability problems associated to exhaustive use of grazing resources have been indirectly approached by European Union authorities, providing support for artiﬁcial plantations over treeless land, no mention is made to natural regeneration techniques. In this sense, the formulated model allows for natural regeneration of already established ageing stands as a complement or even a substitute of actual reforestation practices. The proposed methodology is neither designed to determine optimal rotation of tree species nor optimal decorticating or pruning cycles of cork oaks and holm oaks, respectively. Instead, this information enters the model exogenously through knowledge of region speciﬁc silvicultural cycles for those commercially relevant tree species, and the optimisation program acts as an optimal land use allocator and thus a practical tool for policy analysis purposes. In addition to existing cost beneﬁt analysis applications in dehesa ecosystems, the presented model allows in one side eﬃcient evaluation of long term management dynamics —thus oak woodlands sustainability can be tested for suﬃciently large time horizons—, and in the other, management decisions, instead of being forced through predeﬁned scenarios, correspond to the optimal actions a decision agent would take from the complete set of feasible possibilities given actual land use and tree age distributions.</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%">Rosalino, Luís Miguel</style></author><author><style face="normal" font="default" size="100%">Torres, Jordi</style></author><author><style face="normal" font="default" size="100%">Santos-Reis, Margarida</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">A survey of helminth infection in Eurasian badgers (Meles meles) in relation to their foraging behaviour in a Mediterranean environment in southwest Portugal</style></title><secondary-title><style face="normal" font="default" size="100%">European Journal of Wildlife Research</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%">diet</style></keyword><keyword><style  face="normal" font="default" size="100%">endoparasites</style></keyword><keyword><style  face="normal" font="default" size="100%">helminths</style></keyword><keyword><style  face="normal" font="default" size="100%">meles meles</style></keyword><keyword><style  face="normal" font="default" size="100%">Portugal</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2006</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2006///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.springerlink.com/index/10.1007/s10344-006-0033-7</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">52</style></volume><pages><style face="normal" font="default" size="100%">202 - 206</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">This study provides the first data on the helminth fauna of the Eurasian badger in the southwestern edge of its range (Grândola Mountain, Portugal) and interprets the results in relation to badger diet and feeding behaviour. By examination of 163 badger faecal samples, faecal developmental stages (eliminative forms) of four helminth species and one genus were identified: one cestode (Atriotaenia incisa) and four nematodes (Mastophorus muris, Molineus patens, Uncinaria criniformis and Strongyloides sp.). The overall prevalence of parasites was 62%, with limited seasonal variation. Single parasite excretions were dominant and Strongyloides sp. excretion was the most common. Diet assessment based on 450 faecal samples revealed that badgers consumed mainly insects and fruits. No correlation was detected between helminth prevalence and diet. Apparently, diet (mainly insects) and feeding behaviour (fossorial), together with the species’ social behaviour (anal scent marking of group members), facilitate the infection with helminths. The helminth fauna of Eurasian badgers in Grândola Mountain has isolationist characteristics, apparently indicating low host colonisation.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue></record></records></xml>
