Patterns of chromosomal evolution in Sigmodon, evidence from whole chromosome paints.
Of the superfamily Muroidea (31 genera, 1578 species), the Sigmodontinae (74 genera, 377 species) is the second largest subfamily in number of species and represents a significant radiation of rodent biodiversity. Only 2 of the 74 genera are found in both North and South America (Sigmodon and Oryzomys) and the remainder are exclusively from South America. In recent molecular studies, the genus ...
متن کاملDeleterious mutations at the mitochondrial ND3 gene in South American marsh rats (Holochilus).
Statistical analyses of DNA sequences have revealed patterns of nonneutral evolution in mitochondrial DNA of mice, humans, and Drosophila. Here we report patterns of mitochondrial sequence evolution in South American marsh rats (genus Holochilus). We sequenced the complete mitochondrial ND3 gene in 82 Holochilus brasiliensis and 21 H. vulpinus to test the neutral prediction that the ratio of no...
متن کاملSystematics of Argentinean, Paraguayan, and Uruguayan Swamp Rats of the Genus Scapteromys (rodentia, Cricetidae, Sigmodontinae)
We present a systematic study of Scapteromys populations from Argentina, Paraguay, and Uruguay, based on molecular and morphological evidence. First, based on DNA sequences (801 base pairs) from the mitochondrial cytochrome-b gene, we found that Scapteromys populations fall into 2 main clades; 1 formed by Argentinean and Paraguayan populations together with 1 population from western Uruguay, an...

Noronhomys vespuccii, a new genus and species (Muridae: Sigmodontinae), is described from Ilha Fernando de Noronha, a small volcanic island located 345 km northeast of Cabo de Sao Roque, Brazil. The abundant cranial and postcranial material of the fossil rodent was recovered from old beach dunes that are late Quaternary in age (probably late Holocene). Noronhomys vespuccii retains incomplete me...
