Abstract:

We present the revalidation of the sigmodontinae rodent species R. emiliae, as well as the description of a new species for the genus Rhipidomys. The maximum likelihood analysis recovers R. emiliae as sister species of the clade with Rhipidomys sp. nov. and R. ipukensis, with high bootstrap values. Comparisons between these species based on the external, cranial, and dental morphology identified several unique characters in Rhipidomys sp. nov., including more grayish brown color of the dorsal coat, subsquamosal fenestra wide and long, angular process ends in the same position of the end of con

Abstract:

Rhipidomys (Sigmodontinae, Thomasomyini) has 25 recognized species, with a wide distribution ranging from eastern Panama to northern Argentina. Cytogenetic data has been described for 13 species with 12 of them having 2n = 44 with a high level of autosomal fundamental number (FN) variation, ranging from 46 to 80, assigned to pericentric inversions. The species are grouped in groups with low FN (46–52) and high FN (72–80). In this work the karyotypes of Rhipidomys emiliae (2n = 44, FN = 50) and Rhipidomys mastacalis (2n = 44, FN = 74), were studied by classical cytogenetics and by fluorescence

Abstract:

Arboreal rats of the genus Rhipidomys, belong to a taxonomic group of Neotropical distribution, included in the tribe Thomasomyini. In Venezuela, the Rhipidomys fulviventer group contains four taxa (R. fulviventer, R. tenuicauda, R. venustus, and R. wetzeli), only found in high elevation cloud forests and lowland rainforests. Because collections to date do not represent a thorough sampling of their geographic range, taxonomic arrangement of some taxa (e. g., Rhipidomys venustus), has been controversial. However, new specimens collected in recent years provide novel insights into the biogeograp

Abstract:

The mid-Araguaia River basin in central Brazil is considered a priority area for biodiversity conservation, and Parque Estadual do Cantão (PEC) is one of the most important protected areas in this ecotone between Cerrado and Amazonia. This area suffers an intensive human pressure with high rates of deforestation, and still remains poorly studied in terms of biodiversity. From June 2007 to November 2008 we sampled small mammals from both banks of the mid-Araguaia River, in the states of Tocantins and Pará.

Catching animals other than birds and bats in mist-nets is exceptional, so our record is one of the few reported in the literature and involving a rodent. Presumable the individual became entangled while foraging in the vegetation surrounding the mis-net.

Abstract:

Rhipidomys ochrogaster is a poorly known sigmodontine rodent from the Yungas of southeastern Peru, known only from a few specimens collected more than 110 years ago. This work reports a new specimen from Yanacocha, Puno, Peru, collected on 22 May 2010; provides a morphological description and comparisons with R. leucodactylus and R. gardneri; characterizes the habitat; and presents data on the diet of the species. This discovery stresses the urgent need for additional inventory work in the region, in order to document its biodiversity.

Abstract:

We evaluated the role of communities of small mammals from three distinct areas in a region of Cerrado mixed with Atlantic Forest remains for maintenance of tick fauna. Thirty-nine marsupials (Gracilinanus agilis, n = 34; Marmosa paraguaiana, n = 4; Didelphis albiventris, n = 1) and 33 rodents (Oecomys cleberi, n = 10; Nectomys squamipes, n = 4; Calomys tener, n = 4; Hylaeamys megacephalus, n = 4; Akodon sp., n = 3; Rattus rattus, n = 3; Cerradomys subflavus, n = 2; Mus musculus, n = 2; Rhipidomys macrurus, n = 1) were captured.

Abstract:

The suspended pitfall demonstrates a new and simple mechanism to capture small arboreal and scansorial mammals. It is an arboreal version of the pitfalls traditionally used to capture terrestrial amphibians and reptiles. Buckets with bait inside are raised by a rope until they reach a tree branch at the desired height. Tests were performed in the Atlantic Forest at three different sites at the mouth of Doce River in Linhares, southeastern Brazil. In one of them suspended pitfalls were set up in the understory of a shaded cacao plantation (cabruca agroforest) in the branches of cacao trees betw

Abstract:

The Chapada Diamantina (CD) is located in Bahia State, between 11-14° S and 41-43° W, being part of the Serra do Espinhaço. The occurrence of different habitats and transition areas permits an interesting mammal fauna composition, with species from different biomes living in sympatry. Species of Didelphimorphia and Rodentia are important members of mammal communities in almost all different habitats, and morphological and cytogenetic characters are important for a correct identification of most of these species. In this work 258 specimens of small mammals from the orders Didelphimorphia (six g

Abstract:

Introduction: Sources of pathogenic Rickettsia in wildlife are largely unknown in Brazil. In this work, potential tick vectors and seroreactivity of small mammals against four spotted-fever group Rickettsia (R. rickettsii, R. parkeri, R. amblyommii and R. rhipicephali) and Rickettsia bellii from peri-urban areas of Uberlândia, a major town in Brazil, are described for the first time. Methodology: Small mammals were captured and blood samples collected. Ticks were collected from the surface of the host and the environment and posteriorly identified.

Abstract:

The characterization of patterns of hair microstructure is an important instrument for studying the diet and ecology of mammals, representing an accessible method for identifying predators and their prey. The present study aimed to: (1) describe methodological adaptations developed to optimize traditional guard hair analysis protocols; (2) propose adjustments in the classification of morphological patterns of medulla and cuticle; and (3) establish the microstructural pattern of Brazilian mammals’ hair to assist in the identification of prey and predators in studies based on fecal samples.

Abstract:

This study investigated the occurrence of Giardia duodenalis and Cryptosporidium spp. in rodents and marsupials from the Atlantic Forest in southern Bahia, northeastern Brazil. Two hundred and four fecal samples were collected from different forest areas in the municipalities of Ilhéus, Una, Belmonte, and Mascote. Identifications were performed using PCR and nested PCR followed by sequencing of the gdh and tpi genes for G. duodenalis, and the gp60 and Hsp-70 genes for Cryptosporidium. The total frequency of positive PCR samples for both G. duodenalis and Cryptosporidium spp. was 5.4% (11/204).
