Morphological divergence in insular and mainland populations of the European glass lizard, Pseudopus apodus (Squamata: Anguidae)
The European glass lizard, Pseudopus apodus (Pallas, 1775) is a large, legless lizard that can be found both on the mainland and on many Mediterranean islands. Our research focuses on two populations of the European glass lizard from the eastern Adriatic coast, one from mainland (Klis), and one from an island (Cres). We studied morphology and scaled mass index (SMI) and tested if insular P. apodus are different than the mainland population. In addition, we explored possible differences in habitat utilization between these populations. We predict a larger body size and a more pronounced sexual dimorphism in the island population, since islands usually comprise specific conditions to which populations respond by changes in behaviour, ecology, morphology, or physiology. We sampled 164 individuals ; 92 from Klis, and 72 from Cres Island and showed that the European glass lizard exhibits size differences between the populations. In addition, the Cres Island population showed clear sexual dimorphism which is lacking in the mainland population. Some ecological characteristics of this species are similar in both populations (soil temperature, distance to the hiding place) and are not influenced by habitat differences. However, the vegetation cover differs between two sites, with more vegetation present in Klis than on Cres.
