dc.description.abstract | 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 affect fitness. In Phyllotis xanthopygus, a small altricial rodent inhabiting an altitudinal gradient in the Andes Mountains of Argentina, the behavioral response to temperature varies between populations from different altitudes. Animals from high altitude (cold environment) reduce their activity rate at high temperatures, in contrast to animals from low altitude (relatively warmer environment). The goal of this study was to unveil the mechanism underlying such intraspecific behavioral variability in P. xanthopygus. We characterized activity rates under different thermal treatments both for wild-reared and lab-reared animals. As we expected, the intraspecific variability shown by animals raised at different altitudes in the field disappeared in animals raised under homogenous conditions in the laboratory. Our results are indicative of ontogenetic plasticity in P. xanthopygus and suggest that the behavioral versatility of adult individuals to deal with thermal challenges is shaped by the range of environmental conditions experienced during their early life. This adds to the list of features that modulate the biological performance of individuals and could influence the relative vulnerability of populations inhabiting different elevations under the global disturbance of climate change. | eng |
