From: Fine-scale genetic structure among greater sage-grouse leks in central Nevada
The RDA plot illustrates the strong relationship between geography and population genetic structure for sage-grouse in central Nevada. Mean RDA scores are plotted for each individual and vectors depict the direction of the two predictor variables (latitude and longitude) relative to the RDA axes. The proportion of variance explained by each RDA axis is listed on each axis label. 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)
