Divergence in Zygodontomys (rodentia: Sigmodontinae) and distribution of amazonian savannas.
Northern South America presents a diverse array of nonforest or savanna-like ecosystems that are patchily distributed. The distribution of these open habitats has been quite dynamic during Quaternary glacial-interglacial cycles; yet, the relevance of climatically driven vicariance events to the diversification of nonforest Amazonian vertebrates remains poorly known. We analyzed karyologic and m...
متن کاملA new karyotype of Oligoryzomys (Sigmodontinae, Rodentia) from central Brazil.
A new karyotype of the genus Oligoryzomys was described for specimens collected in Brazilian Cerrado in Tocantins and Goiás States. Conventional staining, G-, C-banding, and Ag-NOR staining techniques were used for describe this karyotype with 2n=70, AN=74 or 76. The chromosome complement, with the highest diploid number known among Oligoryzomys species, differs from all others previously repor...
متن کاملMorphology of the Digestive Apparatus in Oligoryzomys nigripes (Rodentia, Sigmodontinae)
Although the Genus Oryzomys is widely distributed in the Americas, there are very few published data on the morphology of this rodent group. Notably, in relation to the digestive apparatus, the data are sparse and fragmented. In addition, because rodents are important animal models, this information may be useful in recent and promising areas for applied studies, such as clinical, therapeutic, ...
متن کاملNew Pedetidae (Rodentia: Mammalia) from the Mio- Pliocene of Africa Nuevos Pedetidae (Rodentia: Mammalia) del Mio-Plioceno de Africa
Pedetidae, or springhares, are represented by a single extant genus (Pedetes) and five extinct ones (Parapedetes, Megapedetes, Propedetes, Rusingapedetes and Oldrichpedetes of which the latter two are new). The fossil record of pedetids tends to be scanty, but remains have been found in Southern Africa, East Africa, the Maghreb, the Arabian Peninsula, Turkey and Greece. Most of the localities h...
متن کاملA new species of Calomys (Rodentia: Sigmodontinae) from Eastern Brazil
On the basis of combined analyses of karyotypic, molecular and morphologic data, we herein describe a new Calomys species collected in a transitional area between the Atlantic Forest and the Cerrado morphoclimatic domains of eastern Brazil. This new taxon differs from all other Brazilian Calomys species by its diploid number (2n=38), the lowest among Brazilian Calomys species, and by its yellow...
