Energetic expenditure during vocalization in pups of the subterranean rodent Ctenomys talarum

Naturwissenschaften, 2004
Theoretical signaling models predict that to be honest, begging vocalizations must be costly. To test this hypothesis, oxygen consumption was measured during resting and begging (i.e., vocalizing) activities in pups of the subterranean rodent Ctenomys talarum by means of open-flow respirometry.

Bioenergetics of Reproduction and Pup Development in a Subterranean Rodent (Ctenomys talarum)

Physiological and Biochemical Zoology, 2002
The objective of this study was to evaluate the maternal costs of reproduction and pup development in the subterranean rodent Ctenomys talarum (Thomas 1898). Statistical differences were detected in whole-animal metabolic rates between nonreproductive and pregnant or lactating females.

Genetically determined polymorphism of two peptidases in the Tuco‐tuco (Ctenomys talarum talarum)

Journal of Zoology, 1972
Six distinct peptidases have been found to occur in the erythrocytes of the Tuco‐tuco. The substrate specificities suggest that these enzymes are homologous with the peptidases previously described in man and the mouse. Common polymorphisms of two of this group of enzymes are described.

Population dynamics of the fossorial rodent Ctenomys talarum (Rodentia: Octodontidae)

Journal of Zoology, 1998
AbstractAs part of a study on the ecological strategies related to adaptation to the subterranean habitat of genus Ctenomys (tuco‐tucos), a natural population of C. talarum was live‐trapped at Necochea (Buenos Aires Province, Argentina) with the aim of providing information on its population ecology.

Sexual selection in a polygynous rodent (Ctenomys talarum): an analysis of fighting capacity

Zoology, 2012
The South American subterranean rodent genus Ctenomys (Caviomorpha: Octodontoidea), which uses both claws and teeth to dig, shows striking morphological adaptations to its specialized mode of life. Among other traits, the genus has evolved a powerful jaw musculature and procumbent incisors that are used for dento-excavation.

Breeding biology of the fossorial rodent Ctenomys talarum (Rodentia: Octodontidae)

Journal of Zoology, 1997
The paper describes the breeding biology of the South American herbivorous fossorial rodent Ctenomys talarum (tuco‐tuco), covering the following aspects: length of breeding season, prenatal mortality, mean litter size and its correlates, sex ratio and its density‐dependence, and late sexual maturity of both sexes.
