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...

Neither variation loss, nor change in selfing rate is associated with the worldwide invasion of [i]Physa acuta[/i] from its native North America

International audience. Whether bioinvasions are associated with a loss of genetic diversity and a change in mating system is instrumental for understanding the evolutionary fate of invasive species. Little loss is ...

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 ...
