A new living species of degu, genus Octodon (Hystricomorpha: Octodontidae)
(Alliance Communications Group Division Allen Press, 2021-02)
We 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. ...
Prolagostomus amplus Ameghino is a Junior Synonym of the Patagonian Rodent Pliolagostomus notatus Ameghino (Chinchillidae; Early Miocene, Santa Cruz Formation)
(Asociación Paleontológica Argentina, 2019-05)
Chinchillidaeis a group of caviomorph rodents poorly represented in recent times that includes six living species grouped in three genera, Chinchilla Bennett, 1829, Lagidium Meyen, 1833 and Lagostomus Brookes, 1828 (e.g., ...
Uncovering the species diversity of subterranean rodents at the end of the World: three new species of Patagonian tuco-tucos (Rodentia, Hystricomorpha, Ctenomys)
(PeerJ Inc, 2020-04)
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. In this contribution, we assessed the taxonomic ...
Geographic variation in quantitative skull traits in the genus Myoprocta Thomas, 1903 (Rodentia, Dasyproctidae) and its taxonomic implications
(De Gruyter, 2019-05)
The genus Myoprocta Thomas, 1903 includes two living species of medium-sized caviomorph rodents of the family Dasyproctidae, the red acouchi, Myoprocta acouchy (Erxleben 1777), and the green acouchi, Myoprocta pratti Pocock ...
Redescription and phylogenetic position of Ctenomys dorsalis Thomas 1900, an enigmatic tuco tuco (Rodentia, Ctenomyidae) from the Paraguayan Chaco
(De Gruyter, 2019-05)
Ctenomys dorsalis is known only from its type specimen, a female preserved as skin without skull (except for the upper incisors) from an imprecise locality in the "Northern Chaco of Paraguay". Here, we report additional ...
Bone morphology of the hind limbs in two caviomorph rodents
(2013-04-01)
In order to evaluate the hind limbs of caviomorph rodents a descriptive analysis of the Cuniculus paca (Linnaeus, 1766) and Hydrochoerus hydrochaeris (Linnaeus, 1766) was performed using anatomical specimens, radiography, ...
Testing the quick meal hypothesis: the effect of pulp on hoarding and seed predation of Hymenaea courbaril by red-rumped agoutis (Dasyprocta leporina)
(Blackwell Publishing, 2006-02-01)
Red-rumped agoutis (Dasyprocta leporina) are important seed dispersers/predators of Neotropical large-seeded plants. Several species of seeds cached by agoutis have an edible reward, in contrast to temperate rodent-dispersed ...
