Mutational load and adaptive variation are shaped by climate and species range dynamics in Vitis arizonica.

Abstract excerpt

Genetic load can reduce fitness and hinder adaptation. While its genetic underpinnings are well established, the influence of environmental variation on genetic load is less well characterized, as is the relationship between genetic load and putatively adaptive genetic variation. This study examines the interplay among climate, species range dynamics, adaptive variation, and mutational load - a genomic measure of...
