High genetic variance in life-history strategies within invasive populations by way of multiple introductions

Archive ouverte | Facon, Benoit | CCSD

Biological invasions represent major threats to biodiversity as well as large-scale evolutionary experiments. Invasive populations have provided some of the best known examples of contemporary evolution, challenging the classical ...

Correlated evolution of mating strategy and inbreeding depression within and among populations of the hermaphroditic snail physa acuta

Archive ouverte | Escobar, Juan-Sebastian | CCSD

International audience. Inbreeding depression is one of the main forces opposing the evolution of self-fertilization. Of central importance is the hypothesis that inbreeding depression and selfing coevolve antagonis...

Hybridization and invasiveness in the freshwater snail Melanoides tuberculata: hybrid vigour is more important than increase in genetic variance.

Archive ouverte | Facon, Benoit | CCSD

Many invasive taxa are hybrids, but how hybridization boosts the invasive process remains poorly known. We address this question in the clonal freshwater snail Melanoides tuberculata from Martinique, using three parental and two h...
