Plant biodiversity in the past and present

Scientific objective

To understand the processes underlying past and present diversity of biological entities.


Current research builds on characterization of the diversity of forms and functions under ecological and physiological influences; how assembly rules and interspecific interactions influence the diversity of taxa; how phylogenetic diversity is related to evolutionary, macro-ecological, or biogeographical hypotheses. Our participation in major international networks and our increasing involvement in the management and exploration of collections and observatory data, enable a synergy between native data, and theoretical and methodological developments. This advantage allows us to conduct comparative studies between different regions of the world. Tropical rain forests and fossil floras are our main case studies, but we are also interested in other temperate and tropical biomes.

Expected results

To provide forest managers, and the general public with (i) basic knowledge on species, (ii) tools and methods for characterizing their diversity at various levels of observation (evolutionary lineages, vegetation stands), (iii) predictive models of the dynamics of diversity in space and over time, notably in response to global changes.
