Effects of Acute and Chronic Exposure to Predatory Cues on Spatial Learning Capabilities in the Subterranean Rodent Ctenomys talarum (Rodentia: Ctenomyidae)
(Wiley Blackwell Publishing, Inc, 2014-02)
Spatial learning, the cognitive ability that allows animals to efficiently locate food, partners or avoid predators, can be affected by various factors such as stress. Stressors represent a threat to the animal's homeostasis ...
Preferential use of one paw during feeding in the subterranean rodent Ctenomys talarum
(Soc Royale Zoologique Belgique, 2016-02)
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 ...
Thermoregulatory development and behavior of Ctenomys talarum pups during brief repeated postnatal isolation
(Elsevier, 2014-06)
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' ...
When allowed, females prefer novel males in the polygynous subterranean rodent Ctenomys talarum (tuco-tuco)
(Elsevier Science, 2013-01)
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 ...
Feeding behavior under predatory risk in Ctenomys talarum: nutritional state and recent experience of a predatory event
(Springer Heidelberg, 2019-04)
Predatory risk is recognized as an important factor that impacts on behavior, distribution, and reproduction of animals. Facing the presence of predators’ cues, preys have developed a series of anti-predatory behaviors ...
Female choice, male dominance and condition-related traits in the polygynous subterranean rodent Ctenomys talarum
(Elsevier Science, 2017-09)
Ctenomys talarum is a solitary and highly territorial species in which dominant males aggressively deter other males and monopolize reproductive activity. Female preference for dominant males is not easy to assess due to ...
Dear enemy relationships in the subterranean rodent Ctenomys talarum: The role of memory of familiar odours
(Academic Press Ltd - Elsevier Science Ltd, 2010-06)
Individual recognition is expected to enhance fitness by allowing animals to direct appropriate behaviours to specific individuals during interactions with conspecifics. Reduced aggression towards territorial neighbours ...
Testing detection and discrimination of vegetation chemical cues in the subterranean rodent Ctenomys talarum
(Universita Degli Studi Di Firenze, 2010-07)
Previous studies on the subterranean rodent Ctenomys talarum (tuco-tuco) have shown that this species has the ability to use olfaction to orient their digging while foraging. As a continuation of these works, we assess ...
Effect of ambient temperature on evaporative water loss in the subterranean rodent Ctenomys talarum
(Pergamon-Elsevier Science Ltd, 2015-10)
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. ...
Short-term anxiety response of the subterranean rodent Ctenomys talarum to odors from a predator
(Pergamon-Elsevier Science Ltd, 2015-09)
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 ...
