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 ...
Assessing the energetic costs and trade-offs of a PHA-induced inflammation in the subterranean rodent Ctenomys talarum: Immune response in growing tuco-tucos
(Elsevier Science Inc, 2014-05)
A traditional approach used to assess whether immune defense is costly is to explore the existence of trade-offs between immunity and other functions; however, quantitative studies of the energetic costs associated with ...
Population genetic structure and historical dispersal patterns in the subterranean rodent Ctenomys “chasiquensis” from the southeastern Pampas region, Argentina
(Elsevier Gmbh, 2016-05)
Gene flow plays an essential role in the evolutionary history of the organisms and helps to identify those historical landscape features that most likely had affected the dispersal patterns. In this work, we assess, using ...
Selective binocular vision loss in two subterranean caviomorph rodents: Spalacopus cyanus and Ctenomys talarum
(Nature Publishing Group, 2017)
© 2017 The Author(s). To what extent can the mammalian visual system be shaped by visual behavior? Here we analyze the shape of the visual fields, the densities and distribution of cells in the retinal ganglion-cell layer ...
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. ...
Ecological specialization and niche overlap of subterranean rodents inferred from DNA metabarcoding diet analysis
(Wiley-Blackwell, 2020-07-30)
Knowledge of how animal species use food resources available in the environment can increase our understanding of many ecological processes. However, obtaining this information using traditional methods is difficult for ...
Parasite infection negatively affects PHA-triggered inflammation in the subterranean rodent Ctenomys talarum
(Wiley-liss, Div John Wiley & Sons Inc, 2016-02)
Magnitude and effectiveness of immune responses vary greatly between and within species. Among factors reported to determine this variation, parasitism is a critical one, although controversial effects of parasites over ...
