Supplementary material from "Developmental instability and phenotypic evolution in a small and isolated bear population"
We explored fluctuating asymmetry (FA) and morphological integration (MI) in the skull of the small, highly inbred and divergent Apennine bear ( Ursus arctos marsicanus ), to explore its uniqueness and investigate any potential effects of inbreeding depression. We used 3d geometric morphometrics con...
