Introduction Body size is one of the key phenotypic traits of animals, which affects their morphology, physiology and ecology (Yom-Tov, 2001; Lüpold et al., 2017; Mai et al., 2017; Rollinson & Rowe, 2018). Bergmann’s rule states that, within a species of endothermic vertebrates, smaller individuals

studies among multiple species will shed light on the ecological and evolutionary causes and consequences of behavioral diversity in these ecosystems (e.g., Martins et al., 2008). Intraspecific variation in body size has been shown to affect the antipredatory behaviors of snake species (e.g., Hailey and

Introduction An important issue in evolutionary ecology is the analysis of intraspecific patterns of variation in life-history traits. Amphibian species, characterized by a broad geographical distribution, show a high phenotypic plasticity in growth rate and adult body size. In a lot
