From: Fine-scale genetic structure among greater sage-grouse leks in central Nevada
Sage-grouse population genomic structure mirrors the fine-scale geography of leks. a Mean PCA scores for each lek are denoted by symbols, with segments connecting means and individual points. The proportion of variation explained by each PC is listed on each axis. b PCA scores were rotated onto a standardized geographic matrix to maximize the Procrustes correlation (0.695) between genomic and geographic structure. c A regression with latitude predicting PC1. The legend is ordered from highest to lowest latitude and leks within the same lek complex share the same color (North Cortez = orange; Cortez = red; Pine Valley = purple; Pony Express = Green; Kobeh Valley = blue)
