- Аннотация: Island species are thought to be natural experiments of evolution, as they combine a series offeatures, such as fast evolution or traceable dispersion events, that make them excellent studycases. The Arctic fox (Vulpes lagopus) is one of these cases, as this species lives on the mainlandand in different circumpolar islands. The ecology of this species varies among differentpopulations, mainland ones live in the tundra and feed mainly on lemmings (lemming ecotype)and island ones live near the coast and feed on carrion, eggs and seabirds (coastal ecotype). Here,we use 3D geometric morphometrics to explore skull morphological variation among differentisland and mainland populations. Our results show that all lemming ecotype populations have avery similar skull morphology, whereas each coastal ecotype population has a differentmorphology. However, the patterns of fluctuating asymmetry, a proxy for developmentalpatterns, are very similar among all populations with the only exception of Mednyi islandpopulation. These results suggest that morphological variation of the skull in response ofecological adaptation can follow different paths regardless of the homogeneity of developmentalpatterns.
