Abstract: We studied the structural habitat use and the thermal ecology of Gonatodes humeralis (Guichenot, 1855) in São Luís, Maranhão, Brazil, to examine intersexual differences in the use of perch features and to simultaneously analyze reciprocal differences on thermal ecology between the sexes. Gonatodes humeralis body temperature was strongly correlated with environmental temperatures (air and substrate), but air temperature had an additional effect on the males' body temperatures after removing the effect of the su… Show more

“…Gonatodes humeralis was more associated with open canopy and G. hasemani with fallen logs, which corroborates the microhabitat partitioning in these species described previously (Vitt et al 1997). Gonatodes hasemani uses lower perches with larger diameters primarily because individuals are typically found on fallen logs, whereas G. humeralis uses higher and thinner perches because individuals are typically found on tree trunks and vines (but see Miranda et al 2010).…”

“…For example, U. flaviceps and E. laticeps, both canopy dwellers (Vitt & Torre 1996), were associated with thicker tree trunks, whereas A. ameiva, a typical species from open habitats (Colli 1991, Sartorius et al 1999, Vitt et al 2000, was more captured in areas with open canopy. Gonatodes hasemani uses lower perches with larger diameters primarily because individuals are typically found on fallen logs, whereas G. humeralis uses higher and thinner perches because individuals are typically found on tree trunks and vines (but see Miranda et al 2010).

“…Thus, variations in the body temperature of lizards would be an adaptation of populations to their local thermal environment, changing according to environmental constraints and opportunities for thermoregulation in each location (Hertz et al 1993). Increased knowledge about thermal biology of lizards have shown that the regulation of body temperature in these animals is a complex process, influenced not only by environmental heat sources, but also by characteristics of the ecology and life history of the species (Pianka 1977(Pianka , 1986Huey and Pianka 1983;Adolph and Porter 1993;Rocha et al 2000Rocha et al , 2009aMiranda et al 2010). In general, two or more heat sources interact to determine the body temperature of a lizard.…”
