Data from: Microevolution of S-allele frequencies in wild cherry populations: respective impacts of negative frequency dependent selection and genetic drift

Solenn Stoeckel, Etienne K. Klein, Sylvie Oddou-Muratorio, Brigitte Musch & Stéphanie Mariette
Negative frequency dependent selection (NFDS) is supposed to be the main force controlling allele evolution at the gametophytic self-incompatibility locus (S-locus) in strictly outcrossing species. Genetic drift also influences S-allele evolution. In perennial sessile organisms, evolution of allelic frequencies over two generations is mainly shaped by individual fecundities and spatial processes. Using wild cherry populations between two successive generations, we tested whether S-alleles evolved following NFDS qualitative and quantitative predictions. We showed that allelic variation...

Data from: Fine-scale environmental control of hybridization in oaks

Lélia Lagache, Etienne K. Klein, Erwan Guichoux & Rémy J. Petit
Natural hybridization is attracting much interest in modern speciation and conservation biology studies, but the underlying mechanisms remain poorly understood. In particular, it is unclear why environmental changes often increase hybridization rates. To study this question, we surveyed mating events in a mixed oak stand and developed a spatially-explicit individual-based hybridization model. This model, where hybridization is frequency dependent, pollen is non-limiting and which allows immigrant pollen to compete with local pollen, takes into account...

Data from: Reconstruction of a beech population bottleneck using archival demographic information and Bayesian analysis of genetic data

Tonya A. Lander, Sylvie Oddou-Muratorio, Hélène Prouillet-Leplat & Etienne K. Klein
Range expansion and contraction has occurred in the history of most species and can seriously impact patterns of genetic diversity. Historical data about range change are rare and generally appropriate for studies at large scales, whereas the individual pollen and seed dispersal events that form the basis of geneflow and colonization generally occur at a local scale. In this study we investigated range change in Fagus sylvatica on Mont Ventoux, France, using historical data from...
