Abstract
We used whole-genome resequencing to quantify genetic structure in Black-throated Green Warblers (Setophaga virens) throughout their North American breeding range. center dot We detected low differentiation across all samples but found discrete genetic clustering of S. v. waynei populations that breed along the Atlantic Coastal Plain. center dot We provide evidence of a geographic north-to-south dispersal among the entire species, and found S. v. waynei to be of relatively recent origin within the southern clade. center dot We estimated reduced gene flow in the region separating S. v. waynei from other S. virens populations, but found they were most closely related to a disjunct population from the Piedmont of central North Carolina. center dot We identified two specific regions of the genome that showed elevated differentiation, one on a sex chromosome (Z) and the other on chromosome 6. center dot Our findings provide clarity to the subspecific status of S. virens and bolster conservation efforts for S. v. waynei populations and their habitats.
