Novelties in hybrid zones: crossroads between population genomic and ecological approaches.

ABSTRACT:

Background

Interspecific hybridization is widespread, occurring in a taxonomically diverse array of species. The Cyprinidae family, which displays more than 30% hybridization, is a good candidate for studies of processes underlying isolation and speciation, such as genetic exchange between previously isolated lineages. This is particularly relevant in the case of recent hybridization between an invasive species, Chondrostoma nasus nasus (from Eastern Europe), and C. toxostoma toxostoma (a threatened species endemic to southern France), in which bidirectional introgressive hybridization has been demonstrated.

Methodology/principal findings

We studied 128 specimens from reference populations and 1495 hybrid zone specimens (two years of sampling and four stations), using five m
