Biplot of the first two components of the bioclimatic variables extracted from our sampling locality co-ordinates. Note the rather disparate environmental conditions for the albigula sampling points. All sites where gene flow was recorded (e.g. Mt. Kanga) are characterized by reduced seasonality (variable 4).
