10 pages, 5 figures, 3 tables. We thank J. Sánchez (Director of Los ALcornocales Natural Park) and M. Ater (University of Tetouan) for facilities to carry out the held work. Rafael López and the personnel of the Soil Laboratory in the IRNA made chemical analysis of soil samples. Moli, M. Ángeles, Charo, Begoña, Miriam and Eduardo helped with held sampling.
Afficher plus [+] Moins [-]Three biodiversity parameters – species richness, endemic species richness and taxonomic singularity – have been evaluated for the woody understorey of oakwoodlands on sandstone-derived substrates, on both sides of the Strait of Gibraltar. There is a similarity in floristic composition and ecological distribution of woody plant communities across the Strait. Nevertheless, we have detected significant differences. These include a general reduction in species richness, number of endemic species and taxonomic singularity (at the community level), and a greater abundance of widespread, generalist species, on the southern side (Moroccan) communities, as compared to the north (Spanish ones). We interpret these differences as partly caused by the contrasting management of woodlands, with higher slashing and browsing pressure in Morocco.
