Description of the project (PhD): In ecology, more and more studies search for ecological, evolutionary and historical processes that structure species assemblages by analysing phylogenetic and functional diversity (the latter being the diversity in the biological traits assumed to represent the role species have in their ecosystems, or in the biological traits that influence organism performance) (e.g. Emerson & Gillepsie 2008, Pavoine & Bonsall 2011). 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). A few studies showed that the phylogenetic originality of a species departs from its functional originality (e.g. Cianciaruso et al. 2013).
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. The role original species have in their community and in their region in addition to the impact ecological, historical and evolutionary processes have in the distribution of original species still have to be determined. Such a research is all the more important that original species may be rare (low population size) and potentially vulnerable (Mouillot et al. 2013). In this context, the objective of this PhD project will be to measure, analyse, and model the relative originality of species from different taxonomic groups, along environmental gradient or in distinct habitats to link the phylogenetic and functional originalities of species to ecological, evolutionary and historical processes that shape assemblages.
