Speciﬁcally, the eligibility criterion considered is compliance with minimal requirements of long-term economic and agroenvironmental sustainability. To this end, 69 range farms were surveyed in Extremadura (SW Spain). In these farms, sustainability was studied using the MESMIS framework. MESMIS is based on the evaluation of basic attributes of sustainability (adaptability, self-reliance, equity, stability, and productivity) formed from different indicators. The original indicators are then synthesized by means of qualitative, quantitative, or mixed techniques into a single value measuring the sustainability of the system (sustainability index). Alternative scenarios were then deﬁned in which the perception of CAP subsidies was to a greater or lesser extent linked to levels of sustainability. For each of these scenarios, the economic indicators of the farms were compared with those of the baseline (present) situation. The analysis was completed using a logistic model classiﬁcation to study the relationship between the maximum levels attainable by the economic indicators in terms of the sustainability indices. The results showed that including sustainability as a condition for receiving aid under the CAP can contribute to improving the economic results of traditional extensive farms.</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Elsevier B.V.</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Patón, Daniel</style></author><author><style face="normal" font="default" size="100%">García-Herrera, Ricardo</style></author><author><style face="normal" font="default" size="100%">Cuenca, Javier</style></author><author><style face="normal" font="default" size="100%">Galavis, Mamen</style></author><author><style face="normal" font="default" size="100%">Roig, Fidel</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Influence of Climate on Radial Growth of Holm Oaks (Quercus Ilex Subsp.

Owing to ecological factors such as temperature, rainfall and soil types, the predominant landscape of the territory is formed by Mediterranean clymatophylous series, whose main emplacements vary a function of the bioclimatic floor. Thus, the mesomediterranean feactures the holm oak (Quercus rotundifolia) and the cork oak (Quercus suber); the supramediterranean, the oak (Quercus pyrenaica), and the oromediterranean, formations of genista (Cytisus oromediterraneus, Echinopartum barnadesii, Genista cinerea subsp. cinerascens).Edaphohygrophylous series are represented by stands of alder (Alnus glutinosa), ash (Fraxinus angustifolia), willow (Salix sp. pl.), box-leafed broom (Securinega tinctoria) and oleander (Nerium oleander). In order to complete our knowledge of this landscape, of special relevance is the single-stratum vegetation colonizing biotopes such as cliffs and gravel pits, wich serve as a refuge to most of the endemic vegetation of Extremadura. On the quartzite rocks crowning the Silurian series, one finds as permanent communities the heliophobic fissuricolous communities belonging to the association Asplenio billotii-Cheianthetum hispanicae the heliophylous association of Diantho lusitani-Jasionetum tomentosi and, at the base of rock formations and isolated bocks the saxicolous communities of Digitali thapsi-Dianthetum lusitani and Phagnalo saxatilis-Rumicetum indurati. These biotopes have an endemic arbustive vegetation definided by Adenocarpetum argyrophylli.</style></abstract><notes><style face="normal" font="default" size="100%">doi: 10.1080/11263509609439514</style></notes><research-notes><style face="normal" font="default" size="100%">doi: 10.1080/11263509609439514</style></research-notes></record></records></xml>
