Species viability is strongly connected to the degree of gene flow within and among populations. Such genetic population connectivity may closely track demographic population connectivity or, alternatively, the rate of gene flow may change relative to the rate of dispersal. In this study, we have explored the relationship between genetic and demographic population connectivity using the Scandinavian brown bear as model species, due to its pronounced male dispersal and female philopatry. Our expectation, based on published demographic data, was that the philopatric females shape genetic structure locally whereas the dispersing males act as genetic mediators among regions. To test this, we used eight validated microsatellite markers on 1531 individuals sampled non-invasively during country-wide genetic population monitoring in Sweden and Norway from 2006 to 2013. First, we determined sex-specific genetic structure and substructure across the study area. Second, we compared genetic differentiation, ... : Genotype profilesGeoreferenced genotypes based on 8 microsatellite markers of 1531 brown bears in ScandinaviaData_DRYAD.xlsx ...
