| guerrerostrongylus marginalis n. sp. (trichostrongyloidea: heligmonellidae) from the guianan arboreal mouse (oecomys auyantepui) from french guiana. | based on the number and arrangement of cuticular ridges and configuration of the dorsal ray, nematode specimens collected from the small intestine of eight guianan arboreal mice, oecomys auyantepui (rodentia: sigmodontinae), in french guiana are herein described and characterized. guerrerostrongylus marginalis n. sp. (heligmosomoidea: heligmonellidae) shows a synlophe consisting of more than 40 ridges and a unique bursal arrangement with ray 8 (externo-dorsal) extending to the edge of the bursal ... | 2016 | 26956220 |
| intense genomic reorganization in the genus oecomys (rodentia, sigmodontinae): comparison between dna barcoding and mapping of repetitive elements in three species of the brazilian amazon. | oecomys thomas, 1906 is one of the most diverse and widely distributed genera within the tribe oryzomyini. at least sixteen species in this genus have been described to date, but it is believed this genus contains undescribed species. morphological, molecular and cytogenetic study has revealed an uncertain taxonomic status for several oecomys species, suggesting the presence of a complex of species. the present work had the goal of contributing to the genetic characterization of the genus oecomy ... | 2016 | 27830049 |
