Genetic similarity inferred by discriminant analysis of principal components (DAPC).

A representation of genetic relatedness between geographical clusters of black-capped chickadee populations (N = 15) obtained by DAPC. The graphs represent individuals as dots and the populations as inertia ellipses (population abbreviations can be found in Table 1) and scatterplots are based on the first two principal components. Populations with N ≤ 5 were excluded.

本数据集呈现了通过主成分判别分析（Discriminant Analysis of Principal Components，DAPC）获得的15个黑顶山雀地理种群集群间的遗传亲缘关系。该散点图以圆点代表单个个体，以惯性椭圆表征种群（种群缩写详见表1），其构建基于前两个主成分。采样个体数N≤5的种群已被排除。
