First record of Microcavia jayat (Rodentia, Caviidae) in La Rioja province, northwestern ArgentinaPrimer registro de Microcavia jayat (Rodentia, Caviidae) en la provincia de la Rioja, Noroeste Argentino.
(SAREM, 2020-05)
The genus Microcavia includes five living species of caviomorph rodents endemic to southern South America. Microcavia jayat, the most recently described species, was recorded in only seven localities of Chaco Seco, in ...
Systematic and phylogeny of Prodolichotis prisca (Caviidae, Dolichotinae) from the northwest of Argentina (late Miocene-early Pliocene): advances in the knowledge of the evolutionary history of marasSystématique et phylogénie de Prodolichotis prisca (Caviidae, Dolichotinae) du Nord-Ouest de l’Argentine (Miocène tardif–Pliocène inférieur) : avancées dans la connaissance de l’histoire évolutive des maras
(Elsevier France-editions Scientifiques Medicales Elsevier, 2019-01)
During the last decade, the taxonomic, phylogenetic, and evolutionary knowledge of the groups within Caviidae (i.e. Hydrochoerinae, Caviinae, and the stem eocardiids) has been improved and expanded. However, the evolutionary ...
Systematic review of Neocavia from the Neogene of Argentina: Phylogenetic and evolutionary implications
(Polish Academy of Sciences. Institute of Paleobiology, 2018-05)
Caviidae is one of the groups of rodents with the greatest ecomorphological disparity, and with currently three known lineages: Caviinae (cuises), Dolichotinae (maras), and Hydrochoerinae (capybaras). Caviinae include small ...

Locomotion in the fastest rodent, the Mara dolichotis patagonum (caviomorpha; caviidae; dolichotinae)Locomoción en el roedor más veloz, la mara dolichotis patagonum (Caviomorpha; caviidae; dolichotinae)
(Unidad de Zoología y Ecología Animal, Instituto Argentino de Investigación de Las Zonas Aridas, Cricyt, Conicet, 2019-09)
Although rodents can move fast, they are in general considered non-cursorial mammals, with the notable exception of some species within the suborder Caviomorpha which are convergent with small-sized artiodactyls. The mara, ...
A new guinea pig (Rodentia, Caviomorpha) from northwestern Argentina: implications for the origin of the genus Cavia
(Society of Vertebrate Paleontology, 2017-07)
We describe a new caviomorph rodent, Cavia cabrerai, sp. nov. (Caviidae, Caviinae), from the upper levels of Andalhuala Formation (San Fernando Norte locality, Catamarca Province, northwestern Argentina), which represents ...
The oldest species of Dolichotis (Rodentia, Hystricognathi) from the pliocene of Argentina: redescription and taxonomic status of “Orthomyctera” chapalmalense
(Springer, 2021-09)
The Subfamily Dolichotinae comprises two living species, Dolichotis patagonum, an emblematic component of the Patagonian fauna of Argentina, and Dolichotis salinicola, endemic to the Chaco ecoregion. These two species are ...
A new capybara from the late Miocene of San Juan Province, Argentina, and its phylogenetic implications
(Polish Academy of Sciences. Institute of Paleobiology, 2019-01)
A new hydrochoerine rodent, Cardiatherium calingastaense sp. nov. (Caviidae), is described based on the specimen INGEO-PV 87. It was recovered from the late Miocene Las Flores Formation, cropping out at the Puchuzum locality, ...
Small mammals in owl pellets from the Arid Chaco of Córdoba province (Argentina), including the first records of Microcavia jayat (Rodentia, Caviidae) for the province
(Sociedad Argentina para el Estudio de los Mamíferos, 2020-12-29)
A short list of small mammals is provided, from bones found in pellets of the American barn owl (Tyto furcata) collected in four localities in the Arid Chaco of Córdoba province, central Argentina. We identified seven ...
Changing Only Slowly: The Role of Phylogenetic Niche Conservatism in Caviidae (Rodentia) Speciation
(Springer, 2020-04)
The dynamics of species diversification have attracted significant scientific attention in recent decades. Many lineages tend tomaintain their niche characteristics over evolutionary time, a phenomenon known as phylogenetic ...
