La biodiversité du point de vue de la génomique écologique

Séminaire organisé par l’axe 2 : Origine et Evolution de la Biodiversité, de l’IMBE

10h00 - 11h15 : Guillermo Orti (Dept of Biological Sciences, George Washington University)
Baiting for Phylogenetic Fishing

The talk of Guillermo is on how genome – scale molecular markers can be used to set mega-phylogenies and to buid inferences on ancestral environment and past diversification rates. His approach is based on genomic libraries enriched with specific genes by the use of “fishing” probes and he is applying this method on ray finned fishes. Capture of exon to set markers and mega-phylogenies of targeted genes are a promising approach at the interface of evolution and ecology for any organisms.

11h15 - 12h30 : Ivan Paz-Vinas (IMBE, Aix Marseille Université)
Distribution of genetic diversity in dendritic networks : patterns, processes and implications for biodiversity conservation

The talk of Ivan deals with how coupling meta-analytical tools, genetic data simulations and model-choice procedures may help to identify general patterns of genetic diversity and the underlying processes influencing them in complex landscapes such as dendritic river networks, and with how to use multi-species genetic data to sort areas according their conservation priorities. His work is mainly based on freshwater fish taxa but its approaches can be applied on other biological models such as marine or terrestrial organisms.
