Abstract

VILLAVICENCIO, Héctor J.; ACOSTA, Juan C.; BLANCO, Graciela M.  and  MARINERO, José A.. Thermal ecology of the endemic lizard Liolaemus eleodori (Iguania: Liolaemidae) in National Park San Guillermo, San Juan, Argentina. Multequina [online]. 2012, vol.21, n.1, pp.17-23. ISSN 1852-7329.

The thermal ecology of the endemic lizard Liolaemus eleodori was studied at the San Guillermo National Park, Province of San Juan, Argentina. Data were collected during December 2004 and February 2005. Cloacal (Tc), substrate (Ts) and air (Ta) temperatures were registered using a quick reading thermometer. Liolaemus eleodori exhibited a thermo-conformist thermoregulatory strategy with a unimodal pattern of activity, showing a marked preference for a naked ground microhabitat (completely free of vegetation). Our data suggest that the thermoregulatory strategy and use of space and time is strictly related to the harsh climatic conditions of the study site.
