Origin and congruence of taxonomic, phylogenetic, functional and paleoecological diversity patterns

Project description: 
Past conservation strategies have commonly focused on species richness and taxonomic diversity in order to protect threatened, endemic or even common species, but several concerns have already been raised concerning their effectiveness in englobing other biodiversity aspects. More recent approaches stress on the importance of maintaining also species functional and evolutionary processes in order to propose effective conservation strategies for ecosystems persistence at different scales. The Mediterranean basin provides a unique diversity of habitats, within which a succession of colonization events has shaped a remarkable diversity of plant species, but it is also among the most threatened biomes worldwide. Trees are keystone species of terrestrial ecosystems in the region and are relevant surrogates of global biodiversity. Future land use pressures may continue to be critical for Mediterranean biodiversity, as one fourth of the remaining refugia areas are actually located in sectors where human density is very high. In our approach, we aim to identify the complementarity among the tree diversity facets, in order to identify actual and future conservation targets. We will consider key environmental variables and land-use pressures in the Mediterranean region.
