Deer populations dramatically increased over the last decades in Europe. By their selective browsing, they affect some tree species more than others. Climate change also affects tree species differently. My aim is to understand the crossed effects of deer browsing and climate variability on mixed silver ir – Norway spruce – beech stands, using long-term experimental designs, field observations and modelling.

The recent advent of high throughput sequencing and genotyping technologies (NGS) enables the comparison of patterns of polymorphisms at a very large number of markers, which makes it possible to characterize genomic regions involved in the adaptation of organisms to their environment. However, the current statistical approaches to identify genomic signatures of selection are limited by over-simplified demo-genetic models. Furthermore, these methods generally neglect the information on linkage disequilibrium (LD) among genetic markers. The main objective of my PhD is therefore to develop new and improved Bayesian models to detect signatures of selection.
These new models will be directly applied to NGS data from the European BiodivERsA EXOTIC project, which aims to characterize the genetic basis of adaptation during the invasion of a flagship species: the harlequin ladybird Harmonia axyridis.

I work on freshwater snails metacommunities in lesser antilles (Martinique and Guadeloupe). Using two long-term datasets, the main aim of this work is to quantify population dynamics of each species with respect to environment and interspecific interactions.
