It is indisputable that environmental changes, including major climatic events and human disturbances, have a striking impact on the biodiversity of ecosystems. However, understanding the mechanisms that affect and influence the evolution of biodiversity is not a simple task. We approach the problem at the level of model organisms’ genomes. We attempt to describe the genetic diversity variations (in time and space) caused by natural history (e.g., social systems), genetic (e.g., mitochondrial vs. nuclear DNA), but also historical (e.g., environmental changes and human exploitation) parameters. Given their predictive value, the results of these endeavours can significantly contribute, among others, to environment policy decisions. Several of our analyses have lead to practical recommendations for natural or captive population management (South-American dolphins, Galápagos giant tortoises, Galápagos land iguanas, Jamaican boas …).

Analyses of molecular data
By integrating phylogenetic, coalescence, and population genetic approaches, we investigate in several natural populations of (mostly vertebrate) species, the influence of historical factors on the present stratification and levels of genetic diversity. We use multiple molecular markers including microsatellites and SNPs. Furthermore, when gene flow remains low, intra-specific genealogical lineages can be investigated through phylogenetic methods and their diversity correlated to their geographic distribution (= phylogeographic approach). We will concentrate our efforts in the near future on populations of South-American dolphins as well as on large reptile species (such as the Galápagos giant tortoises, Galápagos land iguanas, Jamaican boas, and Komodo dragons).
In-silico and in-vitro simulations
Beside gathering and analyzing new molecular markers in natural populations, we also use population models in computer simulation studies. This approach allows investigating the influence of any combination of relevant parameters on the dynamic of population structure and diversity. The predictions made during simulation studies can then be validated with real data from natural populations. Furthermore, using Caenorhabditis remanei as an eukaryotic model, we have developed in vitro simulations of population events for testing the efficiency and accuracy of existing analytical methods for the inference of population size variation, levels of gene flow, and fragmentation events.
