The disturbance regimes affected plant assemblage composition. Species richness decreased with increasing land use intensity, the Shannon index showed the highest values in grasslands and hay crops. Plant assemblage composition patterns mirrored those of Basidiomycota and Ascomycota. Richness in Basidiomycota, denitrifying bacteria and microbial biomass showed the same trend as that observed for vascular plant richness. The Shannon index pattern of below-ground microorganisms was different from that of plants. The plant γ-diversity component model weakly mirrored those of Ascomycota. Patchy diversity patterns suggest that the maintenance of contrasting land uses associated with different productions typical of agro-silvo-pastoral-systems can guarantee the conservation of biodiversity.</style></abstract><issue><style face="normal" font="default" size="100%">12</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Academie des sciences&lt;br/&gt;accession-num: 25433564</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%">Bagella, Simonetta</style></author><author><style face="normal" font="default" size="100%">Salis, Lorenzo</style></author><author><style face="normal" font="default" size="100%">Marrosu, Gian Marco</style></author><author><style face="normal" font="default" size="100%">Rossetti, Ivo</style></author><author><style face="normal" font="default" size="100%">Fanni, Stefania</style></author><author><style face="normal" font="default" size="100%">Caria, Maria Carmela</style></author><author><style face="normal" font="default" size="100%">Roggero, Pier Paolo</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Effects of long-term management practices on grassland plant assemblages in Mediterranean cork oak silvo-pastoral systems</style></title><secondary-title><style face="normal" font="default" size="100%">PLANT ECOLOGY</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">grazing systems</style></keyword><keyword><style  face="normal" font="default" size="100%">soil features</style></keyword><keyword><style  face="normal" font="default" size="100%">Stocking rate</style></keyword><keyword><style  face="normal" font="default" size="100%">Tillage</style></keyword><keyword><style  face="normal" font="default" size="100%">Trifolium subterraneum</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><volume><style face="normal" font="default" size="100%">214</style></volume><pages><style face="normal" font="default" size="100%">621 - 631</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The assessment of the effects of long-term management practices is relevant in understanding the current patterns of plant assemblages in semi-natural ecosystems. We hypothesized that the variety of management practices across different farming systems under the same ecological conditions directly and indirectly shapes these patterns via the long-term changes induced in soil features. The aims of this paper were to evaluate the influence of two sets of variables describing long-term management practices and soil features on plant assemblages and their importance in the context of Mediterranean silvo-pastoral systems. The analysis of variance revealed that richness and grazing value were not affected at all by grazing livestock species and soil tillage frequency and that they both showed relatively high absolute values for the specific context under study. Trifolium subterraneum was a key species in contributing to grassland grazing value and habitat biodiversity. The Canonical Correspondence Analysis highlighted the influence of management practices and soil features on plant assemblage composition, which was significantly affected by grazing livestock species and stocking rate and by soil pH and K content. The Redundancy Analysis showed that soil pH and related features were in turn affected by stocking rate, supporting our hypothesis that management practices influenced plant assemblage composition directly and indirectly via their long-term effects on soil features. The results also highlighted that a systemic analytical perspective applied at a grazing system scale can be effective in addressing sustainable grassland management issues in Mediterranean silvo-pastoral systems.</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: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS&lt;br/&gt;publisher: SPRINGER</style></notes></record></records></xml>
