Conteúdo:  The thermal ecology and strutural habitat use of two closely related sympatric lizars, Carlia vivax (de Vis) and Lygisaurus foliorum de Vis, were examined in an open sclerophyll forest in subtropical Australia. Comparable mean body temperatures (Tb) and habitat temperatures (Thab) at the point of capture were recorded for both species. However, sex-related differences in the thermal variables for C. vivax, with females displaying higher temperatures than males, resulted in some significant differences in Tb and Thab between the species. Variation in Tb and Thab within and between species was unrelated to time of capture. The difference in Thab within C. vivax suggested that females were selecting warner thermal environments than males. Both C. vivax and L. foliorum used most structural features of their habitat randomly as indicated by a similarity in canopy, shrub, ground, log and litter cover and litter depth between habitat surveys and random surveys. However, C. vivax displayed a preference for ground vegetation (height<1 m) and litter cover with significantly higher cover recorded where these lizards were captured compared with random surveys. There was no effect of sex on structural habitat used by either species. Thus, the warmer thermal environments selected by female C. vivax may differ from those selected by males in sun/shade patterns or additional habitat features not measured in the present study. Significant associations between specific habitat features and Tb... Mostrar Tudo
