Behavioral responses of two small-sized rodents, Phyllotis vaccarum and Abrothrix andina, to energy challenges of high-altitude habitats in the Andes Mountains
(Wiley, 2022-12)In mountain environments, both temperature and food availability vary strongly with altitude, leading to a major challenge to the thermo-energetic balance of organisms. In this sense, the behavioral repertoire is crucial ... -
Phenotypic plasticity in the energy metabolism of a small Andean rodent: Effect of short-term thermal acclimation and developmental conditions
(Wiley, 2021-12)The study of phenotypic variation within species in response to different environments is a central issue in evolutionary and ecological physiology. Particularly, ambient temperature is one of the most important factors ... -
Spatio-temporal variability in the feeding strategy of Andean rodents: the role of ambient temperature and food availability
(Springer, 2023-05)Animals' diets reflect the morpho-physiological and behavioral responses used to obtain nutrients and energy. While optimal foraging theory predicts them in terms of food availability, the obligatory heat model (OHM) ...
