From: Dynamic colonization history in a rediscovered Isle Royale carnivore
(a) Distribution of sampled sites in the Lake Superior basin, and the location of historical reintroductions (solid lines) as well as the potential reintroduction of martens to Isle Royale in 1966 (dashed line). Points and colours correspond to sampling locations and population clusters identified using factorial correspondence analysis (FCA) of microsatellite loci across all sites (b). Fine scale structure was detected, with Isle Royale segregating from Michigan and Ontario martens (c).
