Genetic connectivity of the grey partridge in central northern France in a highly man dominated landscape

Abstract : The loss and fragmentation of the landscape are the main causes of the decline and the extinction of many wildlife species. In this study we test the impact of landscape features on the genetic connectivity of a sedentary bird. Populations of our case study, the grey partridge (Perdix perdix armoricana), occur in central northern France. This is considered as the last bastion of high grey partridge densities in Europe and thus represents a relevant zone for the conservation of P. p. armoricana. Despite a highly man dominated landscape, results from the analysis of 12 microsatellite genotypes suggest the beginning of a genetic structure. This emerging genetic structure can result from the last historical event having occurred in the study area: a massive urbanization since the nineteenth century following the increase of the human density and town surface. Another hypothesis suggests that the weak genetic structure can result from a massive restocking with captive-bred individuals at a more or less recent point in time.
