Última Key to the genera of the Tribe Oryzomyini (Rodentia: Cricetidae: Sigmodontinae) Mastozool. neotrop. Weksler,Marcelo; Percequillo,Alexandre R.. Due to recent phylogenetic and revisionary taxonomic work, the systematics of the Tribe Oryzomyini, the largest group of sigmodontine rodents, underwent profound changes. We present here an artificial key for the genera of this group of rodents, enabling researchers to identify oryzomyines using external, cranial and dental characteristics. We also present the most up-to-date diversity assessment of the tribe, in which we recognize 33 extant and extinct genera (plus three undescribed genus-group taxa) and 130 valid species.

Avulsos de Zool. (São Paulo) Prado,Joyce R.; Percequillo,Alexandre R.. Aegialomys xanthaeolus (Cricetidae: Sigmodontinae) inhabits the arid montane areas of western Ecuador and Peru, and higher elevations in the upper Marañón valley in northern Peru. Some researchers have included this species in broader systematic assessments over the years, but there are no comprehensive studies focusing on intraspecific variation. There are several sources of intraspecific phenotypic variation, including sexual dimorphism and age. These sources may confound the assessment of similarity/dissimilarity among populations, therefore it is essential that non-geographic variation is evaluated before studies on geographical variation and species delimitation are carried out. Here we summarize existing information regarding the geographical... Tipo: Info:eu-repo/semantics/article Palavras-chave: Geographic Distribution; Skull; Ontogeny; Sexual Dimorphism; Morphometrics. Ano: 2011 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0031-10492011000900001 Mammals of the Bodoquena Mountains, southwestern Brazil: an ecological and conservation analysis Zoologia Cáceres,Nilton C.; Bornschein,Marcos R.; Lopes,Wellington H.; Percequillo,Alexandre R.. We carried out a mammalian survey in the neighborhoods of the Serra da Bodoquena National Park, Mato Grosso do Sul state, a region poorly known in southwestern Brazil. During the months of April, May and July 2002 we used wire live trap, direct observation, indirect evidence (e.g. tracks), carcasses, and interviews with local residents to record mammalian species. Fifty six mammal species were recorded, including threatened species (14%). These records were discussed regarding species abundance, distribution, range extension, habitat, and conservation. The geographic distribution and ecology of the poorly known marsupials Thylamys macrurus and Micoureus constantiae in Brazil are emphasized.
