Figure 2 in Effects of islanding on the genetics of Niviventer confucianus (Mamalia: Rodentia: Muridae) populations in the Thousand Island Lake region

Figure 2. Bayesian clustering assignment of individual Niviventer confucianus to three clusters based on nuclear (microsatellite) genetic data. Each vertical column represents one individual, with the length of coloured segments proportional to the assignment strength of that individual to each of the three clusters. Most individuals of populations CS, G, D, DM, LW, L and TS are assigned to Cluster 1 (light grey); most individuals of populations Q, Y, JS and ZD are assigned to Cluster 2 (grey); and most individuals of populations WS, WT, ZD and CF are assigned to Cluster 3 (dark). Combined with the island distribution (Figure 1), a reasonable dispersion history of populations could be postulated: population L and TS might be the dispersion centre of Cluster 1, population Y might be the dispersion centre of Cluster 2, and population WT might be the dispersion centre of Cluster 3. Populations in Clusters 1 and 2 are more closely related based on the value of allele frequency divergence (0.0145).
