Biodiversity of woody species in oak woodlands of southern Spain and northern Morocco

摘要: Abstract Three biodiversity parameters – species richness, endemic richness and taxonomic singularity have been evaluated for the woody understorey of oak woodlands on sandstone-derived substrates, both sides Strait Gibraltar. There is a similarity in floristic composition ecological distribution plant communities across Strait. Nevertheless, we detected significant differences. These include general reduction number (at community level), greater abundance widespread, generalist species, southern side (Moroccan) communities, as compared to north (Spanish ones). We interpret these differences partly caused by contrasting management woodlands, with higher slashing browsing pressure Morocco.
