Thermoregulatory development and behavior of Ctenomys talarum pups during brief repeated postnatal isolation
(Elsevier, 2014-06)
In altricial mammals, the role of the mother and siblings throughout pup's early ontogeny is critical to determine “normal” development in neonates. It has been reported that variations in parental investment during pups' ...
Chromosome synapsis and recombination in simple and complex chromosomal heterozygotes of tuco-tuco (Ctenomys talarum: Rodentia: Ctenomyidae)
(Springer, 2014-06)
The chromosomal speciation hypothesis suggests that irregularities in synapsis, recombination, and segregation in heterozygotes for chromosome rearrangements may restrict gene flow between karyotypically distinct populations ...
Sexual size dimorphism and testis size allometry in tuco-tucos (Rodentia: Ctenomyidae)
(Walter de Gruyter & Co, 2013-02)
We studied sexual size dimorphism (SSD) and testes size allometry in 97 natural populations, including 39 nominal species and 19 unnamed or undescribed forms, of tuco-tucos ( Ctenomys ) from Argentina, Bolivia, Chile, ...
Diversity of tuco-tucos (Ctenomys, Rodentia) in the Northeastern wetlands from Argentina: mitochondrial phylogeny and chromosomal evolution
(Springer, 2012-06)
Tuco-tucos (small subterranean rodents of the genus Ctenomys) that inhabit sandy soils of the area under the influence of the second largest wetland of South America, in Northeastern Argentina (Corrientes province), are a ...
Non-shivering thermogenesis in four species of African mole-rats differing in their sociality
(Wiley Blackwell Publishing, Inc, 2021-09)
Many mammalian species are adapted to living in burrows for most of their lives. Inhabiting such thermally stable environments may influence the variation on the species thermogenic capacity, particularly non-shivering ...
Differential antipredatory responses in the tuco-tuco (Ctenomys talarum) in relation to endogenous and exogenous changes in glucocorticoids
(Springer, 2019-11)
Glucocorticoids participate in the behavioral and physiological responses generated under stressful circumstances coming from different sources—physical and/or psychological. In mammals, the increases of these hormones are ...
Redefining the distributional boundaries and phylogenetic relationships for ctenomids from central Argentina
(Frontiers Media, 2021-07)
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 ...
Environmental factors could constrain the use of long-range vocal signals in solitary tuco-tucos (Ctenomys; Rodentia, Ctenomyidae) reproduction
(International Institute of Ecoacoustics, 2017)
Ctenomys are mainly solitary subterranean rodents. Life underground has advantages (protection against predators, environmental control and reduced competition) but also implies disadvantages (digging costs, coping with ...
The evolution of a highly speciose group in a changing environment: Are we witnessing speciation in the Iberá wetlands?
(Wiley Blackwell Publishing, Inc, 2012-07)
Delimiting species is very conflicting in the case of very young taxa that are in the process of diversification, and even more difficult if the species inhabit a heterogeneous environment. In this case, even population ...
