Metabolic rates and thermoregulatory characteristics of Akodon azarae (Rodentia: Sigmodontinae)

In this work, we evaluated the energetic status, activity daily metabolic rate, thermoregulatory capacity and the existence of torpor in Akodon azarae (Fisher 1829). Basal metabolic rate (BMR) was similar to the expected value from Kleiber´s, and also according to the BMR of phylogenetically related...
