DRYMOREOMYS ALBIMACULATUS PDF

Here we report the first record of Drymoreomys albimaculatus Percequillo, Weksler & Costa, (Cricetidae, Sigmodontinae) in Rio de Janeiro state, Brazil. The recently described taxon Drymoreomys albimaculatus is endemic to the Brazilian Atlantic Forest and its biology and genetics are still poorly known. Herein. PDF | Drymoreomys albimaculatus is a recently-described rodent and an Atlantic Forest endemic. It is rare and has a poorly defined geographic.

Interphotoreceptor retinoid binding protein

It lives in the humid forest on the eastern slopes of the Serra do Mar and perhaps reproduces year-round. The bony palate is broad and short, with the posterior margin between the third molars M3. Bootstrap nodal support indices and Albimacylatus posterior probabilities are shown above the branches, respectively.

On the urethral processlocated in the crater at the end of the penis, a fleshy process at the side, the lateral lobuleis present. Collection localities of Drymoreomys albimaculatus. Within Oryzomyini, Drymoreomys appears to be most closely dryomreomys to Eremoryzomys from the Andes of Peru, a biogeographically unusual relationship, in that the two populations are widely separated and each is adapted to an arid or a moist environment.

Telomeric sequences are found near the centromeres of the sex chromosomes.

Mammal Species of the World: Phylogenetic analyses based on morphological traits and DNA sequences [bp of cytochrome b Cyt b and bp of interphotoreceptor retinoid binding protein IRBP genes] revealed the placement of Drymoreomys albimaculatus in the tribe Oryzomyiniraising to 30 the number of albimacculatus Oryzomyini genera.

On the underparts, the hairs are grayish at the base and white at the tip, except on the throat, chest, and in some specimens groin, where the hairs are entirely white [12] —a trait unique among the oryzomyines.
