Figure 2: Unrooted neighbor-joining cluster analysis diagrams of snow bunting (Plectrophenax nivalis ) breeding populations based on Cavalli-Sforza and Edwards’ (1967) chord distance for microsatellite (Panel a) and Single Nucleotide Polymorphism (SNP) (Panel b) markers. The data were bootstrapped over loci with replacement, using 10000 permutations; numbers at branch sites represent the bootstrap support (%) of the branch (support less than 50% is not shown). Asterisks represent non-migratory (resident) populations; others are migratory populations.
