Figure 4: Distribution of pairwise Hedrick’sG’ST values for the sampled snow bunting
(Plectrophenax nivalis ) breeding populations based on the 101
functional Single Nucleotide Polymorphism (SNP) loci. Pairwise
comparisons identified as under neutral processes (blue dots) fall
within the 99.9% microsatellite marker confidence interval range (shown
as error bars for each population comparison). Divergent (black dots)
and stabilizing (green dots) selection were determined using the same
neutral CI. It was not possible to determine selection status
(“Undetermined’; red dots) due to the neutral microsatellite range
including zero. See Table 2 for descriptions of population codes.
