Fig. 3From: Beringian sub-refugia revealed in blackfish (Dallia): implications for understanding the effects of Pleistocene glaciations on Beringian taxa and other Arctic aquatic faunaDistruct graph of STRUCTURE for groups of sampled populations (K) of four. Distruct graph of STRUCTURE output for assignment of individuals to sampled populations (K), of K = 4. Each column represents an individual with the amount of color indicating the posterior probability of an individual being assigned to a group of that color (membership coefficient [q]). Sampling location number is indicated on the x - axis and correspond to Fig. 2 Back to article page
