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 ...
Telling the Seasons Underground: The Circadian Clock and Ambient Temperature Shape Light Exposure and Photoperiodism in a Subterranean Rodent
(Frontiers Media, 2021-10-01)
Living organisms anticipate the seasons by tracking the proportion of light and darkness hours within a day—photoperiod. The limits of photoperiod measurement can be investigated in the subterranean rodents tuco-tucos ...
Ontogenetic trajectories of key morphofunctional cranial traits in South American subterranean ctenomyid rodents
(Alliance Communications Group Division Allen Press, 2010-12)
Ontogenetic allometries of craniomandibular and dental features linked to digging were analyzed in 5 species of the South American subterranean rodent Ctenomys (tuco-tucos). With the exception of upper incisor procumbency, ...
Female preference for males that have exclusively marked or invaded territories depends on male presence and its identity in the subterranean rodent Ctenomys talarum
(Wiley Blackwell Publishing, Inc, 2018-08)
Territorial scent-marking provides chemical records of male competitive interactions that are available to females, who gain valuable information to assess and identify best quality partners. In this context, the solitary ...
Does acclimation to contrasting atmospheric humidities affect evaporative water loss in the South American subterranean rodent Ctenomys talarum?
(Alliance Communications Group Division Allen Press, 2016-09-27)
Water conservation is challenging for terrestrial life since water is continuously lost through respiration, excretion, and cutaneous evaporation. Total evaporative water loss (TEWL) is an important component of the water ...
Prenatal predatory stress in a wild species of subterranean rodent: Do ecological stressors always have a negative effect on the offspring?
(John Wiley & Sons Inc, 2018-05-21)
In pregnant females, a failed predatory event not only induces individual responses but also represents a significant change in the developmental environment of the offspring, which may lead to modifications in their ...
Agonism Management Through Agonistic Vocal Signaling in Subterranean Rodents: A Neglected Factor Facilitating Sociality?
(Springer, 2018-08)
Communication is inherent to social relationships. Previous papers addressed the correlation between social and communicative complexity, and the origin of sociality in rodents. In subterranean social species, as the number ...
Digestive flexibility in females of the subterranean rodent ctenomys talarum in their natural habitat
(Wiley-liss, Div John Wiley & Sons Inc, 2011-03)
We studied the occurrence of digestive strategies at different levels in females of the subterranean herbivorous rodent Ctenomys talarum living in their natural habitat. We determined the dimensions of different parts of ...
Landscape genetics in the subterranean rodent Ctenomys “chasiquensis” associated with highly disturbed habitats from the southeastern Pampas region, Argentina
(Springer, 2017-12-13)
Studies of genetic differentiation in fragmented environments help us to identify those landscape features that most affect gene flow and dispersal patterns. Particularly, the assessment of the relative significance of ...
Acoustic Communication in Subterranean Rodents
(Springer Verlag Berlín, 2007)
Why study acoustic communication? And why in subterranean rodents? There are several reasons for studying acoustic communication in this particular group of mammals. First, acoustic communication is of great importance to ...
