    Influência do tamanho corpóreo sobre as taxas de aquecimento e resfriamento em lagartos Tropidurus montanus e Eurolophosaurus nanuzae (Squamata: Tropiduridae)
    (Universidade Federal de São Paulo, 2023-06-30) Espelho, Barbara Bortoletto [UNIFESP]; Carvalho, José Eduardo de [UNIFESP]; http://lattes.cnpq.br/6738085765102617; http://lattes.cnpq.br/8702482587522101
    In ectothermic vertebrates, behavioral thermoregulation enables maintenance of body temperature within a certain interval in which various physiological activities are optimized. In lizard, for example, the foraging and reproduction are influenced by the choice of appropriate temperatures in the environment, either by exposing the body (or part of it) to direct or reflected solar radiation, or by contact with the heated substrate. Thus, heating and cooling rates can be determinants of ability to thermoregulate. To better understand the effects of body size of these animals on heat exchange with the environment, in this work we investigated whether smaller lizards of to heliothermic species (Tropidurus montanus and Eurolophosaurus nanuzae, Tropiduridae) exchange heat with the environment faster than larger lizards. We use measurements of heating and cooling rates as a proxy for thermoregulatory capacity in adult subjects of different body sizes. In the end, we can verify whether the thermoregulatory capacity can be explained by the body size of these lizards.
