FUNCTIONAL MORPHOLOGY OF THE MIDDLE EAR OF Ctenomys talarum (RODENTIA: OCTODONTIDAE)
The most significant features observed were the enlarged middle-ear cavity, a round and larger eardrum without pars flaccida, and some features shared with unrelated subterranean rodents like Spalax ehrenbergi and geomyids, possibly as adaptations for low-frequency hearing. Expand
Acoustic signals of a solitary subterranean rodent Ctenomys talarum (Rodentia: Ctenomyidae): physical characteristics and behavioural correlates
It is found that the vocalization range in C. talarum is shifted towards low frequencies, which transmit better in underground burrows and match well the hearing range described for other species of subterranean rodents. Expand
Burrow structure in the subterranean rodent Ctenomys talarum
Analysed the structure of completely excavated burrow systems of Tuco-tuco (Ctenomys talarum), Burrow systems of males and females show the same basic design. The main tunnel occupies 48 % of a… Expand
Digging energetics in the South American rodent Ctenomys talarum (Rodentia, Ctenomyidae)
The present study aims to quantify the energetic cost of burrowing in Ctenomys talarum in natural soil conditions and to compare the energetics data with those reported for other subterranean rodents. Expand
Dietary preferences of two sympatric subterranean rodent populations in argentina
The results of this study show that these species of Ctenomys present a feeding strategy which is adaptative in subterranean rodents due to their high digging cost and to the low available energy to explore in their subterranean environment. Expand
Population biology of the subterranean rodent Ctenomys australis (Tuco-tuco) in a coastal dunefield in Argentina

Nutritional response to different diet quality was examined in the subterranean rodent Ctenomys talarum (tuco-tuco), andCoprophagy was practiced along the day and night following the arrhythmic activity pattern found for this species. Expand
Population and habitat characteristics of two sympatric species of Ctenomys (Rodentia: Octodontidae)
Demography, spatial distribution, body size and habitat characteristics of two sympatric species of Ctenomys have been studied seasonally at Necochea (Buenos Aires Province, Argentina).
