Abstract

Research was conducted on the species Pseudopus apodus (Pallas, 1775) with the aim of evaluating erythrocyte morphology and determining baseline values of erythrocytic nuclear abnormalities (ENA). Samples were taken from two separate populations of glass lizards. The first population inhabits the southern part of Island Cres, where anthropogenic influence is very mild, whereas the second occupies the outskirts of Split, a coastal city characterized by higher levels of anthropogenic influence. Data were analyzed using non-parametric statistic tests with reference to location and gender of sampled individuals. Results showed significantly higher nuclear and cytoplasmic vacuolization in glass lizards from the Split area, along with elevated levels of micronuclei and binuclear erythrocytes. Nuclear abnormalities were slightly elevated within the Cres population of glass lizards, but these results were not statistically significant. No significant differences were found between male and female glass lizards, which leads to a conclusion that both genders respond equaly to environmental stress. Further research is needed to supplement obtained data with reference to seasonal changes and age of individuals.
