An assessment of species limits of the South American mouse genus Oligoryzomys (Rodentia, Cricetidae) using unilocus delimitation methods

Zoologica Scripta, 2019
Oligoryzomys, as currently understood is formed by 25 living species, is the most diverse genus of the tribe Oryzomyini of the New World subfamily Sigmodontinae of cricetid rodents.

Major chromosome homeologies between Muridae and Cricetidae

Cytogenetic and Genome Research, 1985
The presumed ancestral karyotype of Muridae, previously reconstructed, is compared with that of a selected Cricetidae species, <i>Akodon a arviculoides</i>. Most of the chromosomes of the presumed ancestral chromosomes of Muridae are homeologous to chromosome arms or segments in the <i>Akodon</i> karyotype.

Molecular phylogenetics and taxonomy of dwarf hamsters Cricetulus Milne-Edwards, 1867 (Cricetidae, Rodentia): description of a new genus and reinstatement of another.

Zootaxa, 2018
The taxonomy of the genus Cricetulus has been controversial. The phylogenetic relationships both within the genus and among Cricetulus lineages and other genera were examined using a set of five nuclear and two mitochondrial genes.

Reproductive Biology of Ototylomys (Cricetidae)

Journal of Mammalogy, 1975
Reproductive biology of the Neotropical climbing-rat, Ototy- lomys, is described, based on the examination of 86 offspring of animals live- trapped from Campeche, Mexico. Animals were maintained in the Michigan State University Live Animal Colony. Vaginal smears were collected from Ototylomys kept in 14 hours of light and 10 hours of darkness.

Cricetidae—Part 2 (Microtidae)

1994
Microtines are small to intermediate in size. The skull follows the general pattern of cricetids (and all muroids) and is fully myomorphous, the mandible sciurognathous (Fig. 21.1). The rostrum is usually shorter than in other cricetids and the skull is more robust. A postorbital process or ridge may be present on the squamosal. The zygoma is broad.
