Biostratigraphic reassignment of the neogene Caenolestines (Marsupialia) of the pampean region: the case of Pliolestes Tripotamicus Reig, 1955 [PDF]
, 2017 La reinterpretación estratigráfica de un sitio paleontológico controvertido, como las barrancas del río Quequén Salado, permitió ajustar el biocrón del marsupial cenolestino Pliolestes tripotamicus Reig.

Phylogeography of the Subterranean RodentSpalacopus cyanus(Caviomorpha, Octodontidae) [PDF]
Journal of Mammalogy, 2008 Spalacopus cyanus is a subterranean rodent inhabiting coastal and mountain habitats. Individuals from mountain populations are larger than individuals from the coast, and mountain populations have a more limited geographic range. To investigate the genetic structure and biogeography of this species, we analyzed mitochondrial DNA control region ...

PORTAL ORIENTATION AND ARCHITECTURE OF BURROWS IN TYMPANOCTOMYS BARRERAE (RODENTIA, OCTODONTIDAE) [PDF]
Journal of Mammalogy, 2003 The red viscacha rat, Tympanoctomys barrerae , is an octodontid rodent endemic to the Monte and Patagonian deserts of Argentina. It lives in burrows with numerous portals facing different directions. We studied climatic factors as possible determinants of burrow architecture and portal orientation, in 2 populations.

A new living species of degu, genusOctodon(Hystricomorpha: Octodontidae)
Journal of Mammalogy, 2020 AbstractWe combine morphological (qualitative and quantitative data) and genetic (one mitochondrial and one nuclear gene) data from a large set of specimens of Octodon from the four currently recognized living species of the genus. The integration of the results (qualitative assessment, multivariate analysis of cranial measurements, and gene trees ...

¿La disponibilidad del recurso trófico afecta la selección de grietas por Octomys mimax en el Desierto del Monte? [PDF]
, 2015 Rocky habitats have a particular microclimate and a highly complex structure, providing sites that mammals can use as dens or as nesting sites to raise their young.

, 2020 Anatomical middle and inner ear parameters are often used to predict hearing sensitivities of mammalian species. Given that ear morphology is substantially affected both by phylogeny and body size, it is interesting to consider whether the relatively ...

Filling phylogenetic gaps and the biogeographic relationships of the Octodontidae (Mammalia: Hystricognathi) [PDF]
Molecular Phylogenetics and Evolution, 2016 Endemic to South America, octodontid rodents are remarkable by being the only mammal taxa where allotetraploidy has been documented. The taxon's extensive morpho-physiological radiation associated to niche shifts has allowed testing phylogeographic hypotheses.

Eye and vision in the subterranean rodent cururo (Spalacopus cyanus, octodontidae)
The Journal of Comparative Neurology, 2005 Subterranean mammals are generally considered to have reduced eyes and apparent blindness as a convergent adaptation to their lightless microhabitat. However, there are substantial interspecific differences. We have studied the prospect of vision in the Chilean subterranean rodent cururo (Spalacopus cyanus, Octodontidae) by analyzing the optical ...

Comparative chromosomal analysis and phylogeny in four Ctenomys species (Rodentia, Octodontidae) [PDF]
Biological Journal of the Linnean Society, 2000 A cytogenetic chromosome study was carried out on specimens of four species of Ctenomys—C. talarum, C. rionegrensis, C. pearsoni and C. dorbignyi—from 10 different populations. The analysis of chromosomes was performed through sequential uniform stain, G and C-banding, and with restriction enzymes.
