In this work, the changes in fur density and length in the subterranean rodent Ctenomys talarum were evaluated as a possible compensatory mechanism during seasonal temperature changes in their burrow environment and during ...

El género Ctenomys se encuentra ampliamente distribuído en Argentina. Su ausencia en el norte de la provincia de Buenos Aires desde el Holoceno tardío, fue considerada como el resultado de cambios climáticos ocurridos en ...

Predation is a strong selective force, and prey species may show specific adaptations that allow recognition, avoidance, and defense against predators. Facing a situation of predatory risk, anxiety constitutes a reaction ...

First believed as a uniquely human characteristic, the preference to use one extremity for carrying out diverse activities, like feeding or self-grooming, was observed in several groups of vertebrates and even in some ...

In altricial mammals, the role of the mother and siblings throughout pup's early ontogeny is critical to determine “normal” development in neonates. It has been reported that variations in parental investment during pups' ...

The ability to recognize familiar conspecifics plays an important role at the time of choosing a mating partner in rodents. A laboratory study using preference test was used in order to test the hypothesis that, in the ...

Subterranean rodents face unique thermoregulatory challenges. Evaporative water loss (EWL) is a crucial mechanism for maintaining heat balance in endotherms subjected to heat stress but also leads to potential dehydration. ...

Prey organisms exhibit primary adaptations that contribute to avoid predators and secondary mechanisms that allowthemto defend themselves. Particularly behavioral adaptations allowthem to recognize, avoid and defend against ...
