Age and sex-dependent effects of landscape cover and trapping on the spatial genetic structure of the stone marten (Martes foina

摘要: Maintenance of genetic variation is critical importance for wild populations since low levels limit the species’ ability to respond different threats (diseases, predators, environmental changes) in both long and short term. Human activities could impact species multiple ways, including via fragmentation harvesting. We used an individual-based landscape genetics approach describe elements trapping pressure on spatial structure a large sample (n = 370) stone marten (Martes foina) central-eastern France (Bresse). An analysis isolation-by-resistance using causal modeling showed influence cover and/or gene flow according age sex class. Overall, connectivity study area provided mainly by vegetation cover, while roads open areas partially impede it. Unexpectedly this “urban adapter” species, buildings reduce flow. also emphasized sex-dependent effect Genetic differentiation males was influenced only latter females. A stronger isolation distance than females suggested that at scale area, are more exposed pressure, which reduces effective dispersal. combination costs might create ‘ecological trap’ disrupt flow, leading north–south division area.
