Behavioral responses of two small-sized rodents, Phyllotis vaccarum and Abrothrix andina, to energy challenges of high-altitude habitats in the Andes Mountains
Ruperto, Emmanuel Fabián; Menéndez, Josefina; Taraborelli, Paula Andrea; Scattolón, Federico Omar; Sassi, Paola Lorena (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 ... -
Developmental environment influences activity levels in a montane rodent, Phyllotis xanthopygus
Ruperto, Emmanuel Fabián; Taraborelli, Paula Andrea; Menéndez, Josefina; Sassi, Paola Lorena (Elsevier, 2020-10)Ambient temperature and thermal variability play a crucial role in diverse aspects of organisms’ biology. In the current context of climate change, it is critical to understand how temperature impacts traits that could ... -
Phenotypic plasticity in the energy metabolism of a small Andean rodent: Effect of short-term thermal acclimation and developmental conditions
Menéndez, Josefina; Ruperto, Emmanuel Fabián; Taraborelli, Paula Andrea; Sassi, Paola Lorena (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
Ruperto, Emmanuel Fabián; Menéndez, Josefina; Taraborelli, Paula Andrea; Dacar, María Ana; Sassi, Paola Lorena (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) ...
