Comparison of genetic clustering around the Great Lakes using RAD loci and microsatellites. The geographic location (a) of North American Great Lakes populations and their genetic clustering with respect to the first two principal component axes, using: (b) eight microsatellite loci (from Foxe et al. 2010) and (c) 3337 polymorphic RAD loci. Colours distinguish samples from different collection sites, circles represent predominantly outcrossing and triangles highly selfing populations
