Advances in our knowledge on the planet biodiversity have been largely dependent upon biological collections, and today they continue to be the cornerstone of several disciplines. Recently, the Brazilian Society of Mammalogists established the Mammal Collections Committee (CCM-SBMz) aiming to collect, organize and share information on the mammalian...

Zoonoses are diseases or infections naturally transmissible from vertebrate animals to humans, and can be bacterial, viral or parasitic. The growth of urbanization, industrialization and the advance of agriculture and livestock facilitate the spread of infectious and parasitic agents from wild animals to the human population and to their domestic a...

The state of Goiás, in central Brazil, is covered mainly by the Cerrado domain, with the Alto Paraná Atlantic Forest occupying its central-southern portion. Goiás is one of the 20 Brazilian federative units without a mammal checklist. In this study, we provide the first checklist of mammals from Goiás state. We recorded mammal species based primari...

ABSTRACT. Neotropical Felidae as hosts of zoonotic agents in Brazil. Mammals play a central role in the cycle of several zoonoses, the study of their prevalence and distribution is extremely important to prevent outbreaks and create prophylaxis mechanisms. Wild feline species have increasingly in contact with humans, exposing them to possible over...

Despite the relatively short history of the Brazilian Society of Mammalogy (SBMz) with its 31 years, some remarkable women made significant contributions, not only to the SBMz, but also to the Brazilian mammalogy in general. Even before the consolidation of the SBMz, several women, regardless of their position in the society and academy, developed...

DNA barcoding has become a standard method for species identification in taxonomically complex groups. An important step of the barcoding process is the construction of a library of voucher-based material that was properly identified by independent methods, free of inaccurate identification, and of paralogs. We provide here a cytochrome oxidase I (...

Albinism is a condition caused by deletion of genes responsible for melanin production, resulting in the total absence of pigments. This genetic disorder is rare in nature and is known from ten Brazilian bat species, among them Molossus molossus. Here we report the first occurrence of this condition in M. molossus from northeastern Brazil. Since al...

Clyomys laticeps (Thomas, 1909), the broad-headed spiny rat, is a medium-sized semifossorial rodent with spinous pelage, reduced tail, short limbs, and long powerful claws. These characteristics and its very conspicuous tympanic bullae make C. laticeps unique among echimyid rodents. It primarily inhabits the Cerrado domain of central and southweste...
