Both endogenous and exogenous substrates were considered, either through analysis of whole body losses during long term starvation, or through indirect calorimetric measurements. Results show that utilization of fats, during long term starvation, was not related to their body concentration. Even if most of the energy is provided by proteins, as for temperate species, carbohydrates could be used as far as they remain available. Therefore, carbohydrates metabolism seems to be active in "Atipa".
