Cranial morphological variation of Ctenomys lami (Rodentia: Ctenomyidae) in a restricted geographical distribution [PDF]

open access: yesGenetics and Molecular Biology, 2023
The relationship between chromosomal and morphological variation in mammals is poorly understood. We analyzed the cranial size and shape variation in Ctenomys lami concerning to the geographic variation in their chromosome numbers.

Redefining the Distributional Boundaries and Phylogenetic Relationships for Ctenomids From Central Argentina [PDF]

open access: yesFrontiers 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 ...

Comparative Chromosome Painting Clarifies the Intraspecific Chromosomal Variation in Two Ctenomys Species (Rodentia: Ctenomyidae) [PDF]

open access: yesAnimals
Background: Ctenomys is a subterranean rodent genus known for exhibiting the highest levels of chromosome variation, both among species (2n = 10 to 70) and within species.

Investigating the evolutionary dynamics of diploid number variation in Ctenomys (Ctenomyidae, Rodentia) [PDF]

open access: yesGenetics and Molecular Biology
Contrary to predictions from classical hybrid sterility models of chromosomal speciation, some organisms display high rates of karyotype variation. Ctenomys are the current mammals with the greatest interspecific and intraspecific chromosomal variation ...

Natural life cycle of Versteria cuja (Taeniidae) in Argentina and histopathology of metacestodiasis in intermediate hosts [PDF]

open access: yesParasitology, 2023
Using morphological and molecular studies, the life cycle of Versteria cuja (Cestoda: Taeniidae) was elucidated, involving subterranean rodents (Ctenomyidae) as intermediate hosts, and the lesser grison, Galictis cuja (Mustelidae), as definitive host ...

Skull shape and size variation within and between mendocinus and torquatus groups in the genus Ctenomys (Rodentia: Ctenomyidae) in chromosomal polymorphism context [PDF]

open access: yesGenetics and Molecular Biology, 2018
We tested the association between chromosomal polymorphism and skull shape and size variation in two groups of the subterranean rodent Ctenomys. The hypothesis is based on the premise that chromosomal rearrangements in small populations, as it occurs in ...

Natural life cycle and molecular characterization of Taenia talicei Dollfus, 1960 (Cestoda: Taeniidae) from northwestern Patagonia, Argentina [PDF]

open access: yesInternational Journal for Parasitology: Parasites and Wildlife
Through morphological and molecular studies, the natural life cycle of Taenia talicei Dollfus, 1960 (Cestoda: Taeniidae) from Argentine Patagonia is elucidated, involving subterranean rodents (Ctenomyidae) as intermediate hosts, and the Andean fox ...

Uncovering the species diversity of subterranean rodents at the end of the World: three new species of Patagonian tuco-tucos (Rodentia, Hystricomorpha, Ctenomys) [PDF]

open access: yesPeerJ, 2020
Ctenomys Blainville 1826 is one of the most diverse genera of South American caviomorph rodents. Currently, six species of this genus are reported from Patagonia, south of 42°S.
