Grazing disturbance include not only defoliation by animals, but also associated disturbances as animal trampling, soil compaction, and mineralization by deposition of urine and feces. The results show that woodland and dense matorral are more resistant to species loss than middle dense and scattered matorral, or grassland. Information fractal dimension declined as we moved from a dense to a discontinuous matorral, increasing as we moved to a more scattered matorral and a grassland. In all studied cases, the characteristic species of the natural vegetation declined in frequency and organization with grazing disturbance. Heliophyllous species and others with postrate or rosette twigs increased with grazing pressure, particularly in dense matorral. In the more degraded ecosystem, only species with well-adapted traits, e.g., buried buds or unpalatable qualities showed a clear increase with grazing. Indeed, the homogeneity of species distribution within the plant community declined monotonically with grazing impact. Conversely, the spatial organization of the characteristic plants of each community increased in the better-preserved areas, being also related to the sensitivity of the species to grazing impact. The degree of autocorrelation of plant spatial distribution at the species level and the information fractal dimension at the community level allow us to quantify the degree of degradation of natural communities and to determine the sensitivity of key species to disturbance.</style></abstract><issue><style face="normal" font="default" size="100%">4</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%">Alados, Concepción L</style></author><author><style face="normal" font="default" size="100%">ElAich, Ahmed</style></author><author><style face="normal" font="default" size="100%">Papanastasis, Vasilios P</style></author><author><style face="normal" font="default" size="100%">Ozbek, Huseyin</style></author><author><style face="normal" font="default" size="100%">Navarro, Teresa</style></author><author><style face="normal" font="default" size="100%">Freitas, Helena</style></author><author><style face="normal" font="default" size="100%">Vrahnakis, Mihalis</style></author><author><style face="normal" font="default" size="100%">Larrosi, Driss</style></author><author><style face="normal" font="default" size="100%">Cabezudo, Baltasar</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Change in plant spatial patterns and diversity along the successional gradient of Mediterranean grazing ecosystems</style></title><secondary-title><style face="normal" font="default" size="100%">Ecological Modelling</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">fractal analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">grazing systems</style></keyword><keyword><style  face="normal" font="default" size="100%">spatial patterns</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2004</style></year></dates><volume><style face="normal" font="default" size="100%">180</style></volume><pages><style face="normal" font="default" size="100%">523-535</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In this study, we analyze the complexity of plant spatial patterns and diversity along a successional gradient resulting from grazing disturbance in four characteristic ecosystems of the Mediterranean region.

A floristic and phytosociologial study has been done in the Natural Park Sierra de las Nieves, placed in Málaga (Andalusia, Spain). A total of 1.400 taxa have been recorded, fom which we have pointed out and commented 36, due to their biological value as endemisms, rare, protected or endemic species or new records in the studied area. One new taxonomical combination is proposed: Ulex baeticus subsp. bourgaeanus. A total of 78 associations and communities have been recorded. New sintaxa are described: one alliance (Pino pinastri-Juniperion phoeniceae), 12 associations, 9 subassociations and one new combination. The 6 climactic series described with their main tree species, soil and bioclimatic range are the following: two series of Quercus suber (termo-mesomediterranean on schists), one of Quercus rotundifolia (mesomediterranean on limestones), one of Quercus pyrenaica (mcsomediterranean on schists), one of Quercus alpestris (supramediterranean on limestones) and one of Juniperus sabina (oromediterranean on limestones). The 5 edaphoxeric series described with their main tree species, soil and bioclimatic range are the following: two series of Abies pinsapo (meso-supramediterranean on perdotite rocks and dolomite), two series of Juniperus phoenicea (termo-meso-supramediterranean on marble, dolomite and limestones) and one of Pious pinaster (termo-mesomediterranean on peridotite rocks). The 5 riverine edaphoseries described with their main tree species, soil and water-level range are the following: one of Fraxinus angustifolia (summer-droughted rivers on limestones), two of Salix pedicellata (summer-droughted rivers on peridotite rocks, schists and limestones) and two of Nerium oleander (seasonal streams, on peridotite rocks, schists and limestones). Finally, the complete sintaxonomic scheme, with new sintaxa, combinations, hierarchycity and comments on the associations and communities is given</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%">Pérez Latorre, Andrés V.</style></author><author><style face="normal" font="default" size="100%">Nieto, José M.</style></author><author><style face="normal" font="default" size="100%">Cabezudo, Baltasar</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Datos sobre la vegetación de andalucía.
