Immune challenge but not dietary restriction affects spatial learning in the wild subterranean rodent Ctenomys talarum
(Pergamon-Elsevier Science Ltd, 2015-02)
Several lines of evidence suggest that learning and triggering an immune response are both metabolically expensive and thus likely to be subject to nutritional trade-offs between them and other competing demands. Therefore, ...
Rhythmic 24 h Variation of Core Body Temperature and Locomotor Activity in a Subterranean Rodent (Ctenomys aff. knighti), the Tuco-Tuco
(Public Library Of Science, 2014-01)
The tuco-tuco Ctenomys aff. knighti is a subterranean rodent which inhabits a semi-arid area in Northwestern Argentina. Although they live in underground burrows where environmental cycles are attenuated, they display ...
Circadian Pattern of Wheel-Running Activity of a South American Subterranean Rodent (Ctenomys cf knightii)
(TAYLOR & FRANCIS INC, 2009)
Circadian rhythms are regarded as essentially ubiquitous features of animal behavior and are thought to confer important adaptive advantages. However, although circadian systems of rodents have been among the most extensively ...
Modeling natural photic entrainment in a subterranean rodent (Ctenomys aff. knighti), the tuco-tuco
(Public Library Science, 2013-07)
Subterranean rodents spend most of the day inside underground tunnels, where there is little daily change in environmental variables. Our observations of tuco-tucos (Ctenomys aff. knighti) in a field enclosure indicated ...
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 ...
