A methodological workflow for quantitative colouration and colour pattern comparison reveals taxonomic and habitat-level differences in the polymorphic fire salamander (Salamandra salamandra)

Our results revealed an increased prevalence of melanistic colouration and a less homogeneous colour pattern within urban settings, contributing to the limited number of studies about amphibian colouration in anthropic habitats. We outline and discuss alternative hypotheses to explain these patterns, although further investigation is necessary to address several new questions that arise from our results. Leer más.
