    “…SIMPLE SUMMARY: In this paper we studied the body and colour features of the endemic amphibian Salamandrina across its range. Using a multimodel approach and machine learning clustering, we found much difference relative to body size and shape, as well as colour, among populations and between the habitats in which the individuals dwell, while differences between the two species of Salamandrina genus are lower. …”
