Novo artigo. Resumo:
In heliothermic ectotherms, such as lizards, solar radiation is a crucial resource used in thermoregulation and can be limited, especially in species inhabiting forest habitats where open areas suitable for basking are scarce. Lizards Podarcis muralis and Iberolacerta horvathi are similar in morphology and ecology, but show some degree of dissimilarity in physiology, have a widely sympatric distribution but with a partial altitudinal segregation pattern (altitudinal contrasting species densities). We applied spatial statistics to analyse movements in lab experiments with adult male lizards of both species were set up to first test if the presence of conspecifics or heterospecifics has an influence on their thermoregulation.
