Assumed and inferred spatial structure of populations: the Scandinavian brown bears revisited
Abstract We reanalysed the spatial structure of the Scandinavian brown bear ( Ursus arctos ) population based on multilocus genotypes. We used data from a former study that had presumed a priori a specific population subdivision based on four subpopulations. Using two independent methods (neighbour‐...
