Personality underground: evidence of behavioral types in the solitary subterranean rodent Ctenomys talarum [PDF]
PeerJ, 2020 Background Animal personalities have been studied in a wide variety of taxa, but among rodents, available studies are relatively scarce and have focused mainly on social species.

Redefining the Distributional Boundaries and Phylogenetic Relationships for Ctenomids From Central Argentina [PDF]
Frontiers in Genetics, 2021 With about 68 recognized living species, subterranean rodents of the genus Ctenomys are found in a multiplicity of habitats, from the dunes of the Atlantic coast to the Andes Mountains, including environments ranging from humid steppes of Pampas to the ...

Selective binocular vision loss in two subterranean caviomorph rodents: Spalacopus cyanus and Ctenomys talarum. [PDF]
Sci Rep, 2017 AbstractTo 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 and the organization of the visual projections in two species of facultative non-strictly subterranean rodents, Spalacopus cyanus and Ctenomys ...

Non-Invasive Assessment of Adrenal Activity in the Subterranean Rodent Ctenomys talarum in Field and Laboratory Conditions [PDF]
AnimalsThe endocrine stress response is a valuable tool for evaluating how organisms cope with environmental challenges. However, selecting an appropriate matrix for measuring glucocorticoids (GCs) requires careful consideration of sample quality and ...

Growing underground: Development of thermogenesis in pups of the fossorial rodent Ctenomys talarum [PDF]
Frontiers in Ecology and Evolution, 2023 In mammals, during the pup’s development and adult life, integrated requirements of all activities of the individual must conform to a sustained rate of metabolism.

Do subterranean mammals use the Earth’s magnetic field as a heading indicator to dig straight tunnels? [PDF]
PeerJ, 2018 Subterranean rodents are able to dig long straight tunnels. Keeping the course of such “runways” is important in the context of optimal foraging strategies and natal or mating dispersal. These tunnels are built in the course of a long time, and in social

Estimated and in vivo measurements of bite force demonstrate exceptionally large bite forces in parrots (Psittaciformes). [PDF]
J AnatBite force in parrots has been explored using data from muscle masses. The values were validated by comparison with data for bite force collected from live parrots. The parrot's reputation for a strong bite force is well founded. Abstract Jaw morphology and function determine the range of dietary items that an organism can consume.

The genetics of immune and infection phenotypes in wild mice, Mus musculus domesticus
Molecular Ecology, Volume 32, Issue 15, Page 4242-4258, August 2023., 2023 Abstract Wild animals are under constant threat from a wide range of micro‐ and macroparasites in their environment. Animals make immune responses against parasites, and these are important in affecting the dynamics of parasite populations. Individual animals vary in their anti‐parasite immune responses.

The diabetic syndrome in the tuco-tuco (Ctenomys talarum) [PDF]
Diabetologia, 1972 A syndrome of diabetes, which appears to be dependent upon diet, is described in an Argentine rodent, the tuco-tuco. Hyperglycaemia and cataract are shown to be inversely related to age and associated with excess mortality. Pancreatic islet, renal glomerular and lens changes are similar to those of human diabetics.
