Figure 2: Population structure inferred from microsatellite markers.
From: Ecological and genetic impact of the 2011 Tohoku Earthquake Tsunami on intertidal mud snails
The genetic difference of each population was visualized by PCA analysis (a). Filled circles represent populations before the tsunami, and open circles represent populations after the tsunami. The bar plots on the right are the results of Bayesian clustering analysis for each site and each sampling year (b). The color of bars corresponds to cluster membership proportions.
