| allpahuayo virus: a newly recognized arenavirus (arenaviridae) from arboreal rice rats (oecomys bicolor and oecomys paricola) in northeastern peru. | allpahuayo virus was initially isolated from arboreal rice rats (oecomys bicolor and oecomys paricola) collected during 1997 at the allpahuayo biological station in northeastern peru. serological and genetic studies identified the virus as a new member of the tacaribe complex of the genus arenavirus. the small (s) segment of the allpahuayo virus prototype strain clhp-2098 (accession no. ay012686) was sequenced, as well as that of sympatric isolate clhp-2472 (accession no. ay012687), from the sam ... | 2001 | 11384226 |
| genetic and morphological variability in south american rodent oecomys (sigmodontinae, rodentia): evidence for a complex of species. | the rodent genus oecomys (sigmodontinae) comprises ~16 species that inhabit tropical and subtropical forests in central america and south america. in this study specimens of oecomys paricola thomas, 1904 from belém and marajó island, northern brazil, were investigated using cytogenetic, molecular and morphological analyses. three karyotypes were found, two from belém (2n = 68, fundamental number (fn) = 72 and 2n = 70, fn = 76) and a third from marajó island (2n = 70, fn = 72). no molecular or mo ... | 2012 | 23271012 |
| karyotypic divergence reveals that diversity in the oecomys paricola complex (rodentia, sigmodontinae) from eastern amazonia is higher than previously thought. | the genus oecomys (rodentia, sigmodontinae) is distributed from southern central america to southeastern brazil in south america. it currently comprises 18 species, but multidisciplinary approaches such as karyotypic, morphological and molecular studies have shown that there is a greater diversity within some lineages than others. in particular, it has been proposed that o. paricola constitutes a species complex with three evolutionary units, which have been called the northern, eastern and west ... | 2020 | 33119689 |
