dc.description.abstractGLOBAL CLIMATE CHANGE WILL HAVE A GREATER IMPACT ON ECTOTHERMS IN TROPICAL AND SUBTROPICAL COMMUNITIES THAN AT HIGHER LATITUDES, BECAUSE AMBIENT TEMPERATURES ARE CLOSER TO THE UPPER THERMAL LIMITS OF SPECIES. AMPHIBIAN SPECIES ARE HIGHLY DEPENDENT ON EXTERNAL WEATHER CONDITIONS, AND THE EFFECT OF GLOBAL WARMING ON THESE HAS BEEN EVALUATED RECENTLY. THE GREAT CHILEAN FROG (CALYPTOCEPHALELLA GAYI) IS AN ENDEMIC, MONOTYPIC SPECIES AND GENUS WHOSE CONSERVATION STATUS IS CONSIDERED VULNERABLE BECAUSE OF HIGH EXTRACTION PRESSURE FOR HUMAN CONSUMPTION, LACK OF REGULATORY MEASURES AND COMPREHENSION BY ITS CONSUMERS. THEIR POPULATIONS HAVE ALSO DECLINED DUE TO THE LOSS AND DESTRUCTION OF THEIR HABITATS. C. GAYI HAS NOT BEEN CONSIDERED AS AN OBJECT OF PHYSIOLOGICAL STUDY, SO THIS LARGE SPECIES IS NOT KNOWN AS ONE THAT CAN ADAPT TO CURRENT ENVIRONMENTAL CHANGES. IN THIS STUDY WE ANALYZE THE THERMOREGULATORY CAPACITY AND THERMAL EFFICIENCY OF C. GAYI TO DETERMINE ITS POTENTIAL FOR CLIMATIC ADAPTATION. THE RESULTS INDICATE THAT THIS SPECIES IS STRICTLY A THERMAL-CONFORMER; ITS THERMAL EFFICIENCY AND ITS ABILITY TO WITHSTAND HIGH TEMPERATURES ALLOW IT TO SUSTAIN ITSELF UNDER A CLIMATE CHANGE SCENARIO, HOWEVER, IT HAS THERMAL CONSTRAINTS THAT DO NOT ALLOW IT TO WITHSTAND TEMPERATURES GREATER THAN 30°C.
