Última Thermal Ecology Of Pleurodema thaul (Amphibia: Leptodactylidae) Gayana ITURRA-CID,MYRIAM; VIDAL,MARCELA; LABRA,ANTONIETA; ORTIZ,JUAN CARLOS. The biodiversity of the entire planet is threatened by global warming, and among vertebrates, Amphibia is the taxon most negatively affected by this problem. Amphibians depend on an external heat source to achieve and maintain an adequate body temperature, which has a significant impact on their fitness. Therefore, an increase in the average environmental temperature will affect, probably in a negative way, the general performance of amphibians. This makes it imperative to increase our scarce knowledge of amphibian thermoregulation. The aim of this work is to contribute to the knowledge of amphibian thermoregulation by studying the winter thermal ecology of one of the most widely distributed species in Chile, Pleurodema thaul. Individuals were collected...

Microlophus is a lizard genus of South-America which has many species with sexual size dimorphism. An ecological study was performed on M. atacamensis, a species inhabiting the intertidal zone of the coast of northern Chile. The following questions were addressed: (1) does M. atacamensis exhibit sexual dimorphism? (2) do individuals of different age and sex segregate spatially? (3) do individuals of different age and sex use different type of microhabitat? and (4) do individuals of different sexes exhibit differences in thermoregulatory characteristics? The study was conducted in different localities from northern Chile, which include two types of rocky systems used by this species, a high and a low type. At the moment of lizard capture, type of...
