  To ensure the persistence of species facing anthropogenic pressures, an understanding of the dynamics and mechanisms that structure populations is of major importance. Determining the presence of distinct populations is a first step when sympatric populations are suspected. Yellow perch ( Perca flavescens ) is exploited by sport and commercial fishing in Lake Saint-Pierre (Quebec, Canada). Because habitat characteristics are spatially structured and this species is known to display natal site fidelity, this study’s aim was to assess whether sympatric populations of yellow perch coexist in Lake Saint-Pierre. Low genetic differentiation is predicted due to the recent colonization of the system (<8,000 years). Simulations were first performed to confirm that population differentiation is better depicted using AFLP than microsatellite markers. A survey of the variation thr.. View More»
