Phylogenetic and functional originality measures in ecology
The contribution of each species to phylogenetic diversity and to functional diversity can be measured by its originality. A species is original if it has few close relatives (phylogenetic originality) or if it has unique or rare trait states (functional originality). Despite its use in the last two decades in conservation biology (Isaac et al. 2007), the concept of originality is still rarely studied in community ecology.
I'm interested in measuring biodiversity by species originality. I compare distributions of originality within communities and try to explain its role in community assembly at different spatial and temporal scales. Can we use phylogenetic originality as a proxy for functional originality, especially at local (between comunities) scale ? What mechanisms drives species assemblages ? Do they have the same effect at different scales ?
