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 ... -
Developmental environment influences activity levels in a montane rodent, Phyllotis xanthopygus
(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 ... -
Identification of Sarcocystis spp. in synanthropic (Muridae) and wild (Cricetidae) rodents from Argentina
(Springer, 2024)The occurrence of Sarcocystis species was investigated in synanthropic (Muridae) and wild (Cricetidae) rodents from Argentina. Nine species were captured (n = 356). Sarcocysts were detected in muscles of 8.7% (31/356) and ... -
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) ...
