Extended Data Fig. 5: Shifts in patterns of genomic differentiation over time in willow flycatchers breeding across the United States at climate-linked SNPs.

Principal component analysis (PCA) of loci associated with (A) monthly mean dew point temperature (n = 104), (B) monthly precipitation (n = 72), and (C) monthly maximum temperature (n = 56) across 238 contemporary and historical samples of the willow flycatcher. Details as in Fig. 1. Contemporary samples of the four subspecies are shown as squares, circles, diamonds, and triangles, while upside-down triangles indicate historical samples.
