Wild felids play a crucial role in maintaining the ecological balance within natural environments, which are increasingly affected by anthropogenic activities. Various viruses can infect these animals, and there are only two documented cases of Adenovirus occurrence in wild felids. This study aimed to detect Adenovirus DNA in fecal samples of wild...

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...

Roadkill is one of the main threats associated with highways, directly contributing to the depletion of natural populations. Here we establish the effect of landscape, seasonality and climatic variables on roadkill of wild vertebrates on two highways associated with Pedra Azul State Park (PEPAZ), state of Espírito Santo, southeastern Brazil. The hi...

The land crab Johngarthia lagostoma is endemic to Trindade Island, Atol das Rocas, Fernando de Noron-ha and Ascension Islands. The natural history of the species in non-breeding periods is little known. Therefore, here we reported the formation of non-breeding groups and evaluated the chromatic popu-lational pattern of J. lagostoma in Trindade Isla...

Trindade Island has lost much of its original vegetation cover as a result of approximately three centuries of human occupation and intense herbivory caused by invasive mammals. Since the eradication of some of these herbivores, the recovery of some plant species has started. Plantago trinitatis is an endemic herb from Trindade Island, which was co...

Hábitos tróficos de Felis silvestris catus en Isla Tova, Chubut: única población de gatos ferales no asociados a humanos en Argentina. El gato feral (Felis silvestris catus) es una de las especies exóticas responsables de las mayores pérdidas de biodiversidad en el mundo. Los efectos negativos se ven reflejados más fuertemente en islas, en donde la...

Here, we aimed to evaluate the existence of temporal variation in the jaguar's diet and to determine if the adjustments in the diet apply to all prey or if there are species that are more important independently of temporal aspects. The study was carried out in one of the last Atlantic Forest remnants where all potential jaguar's prey are present....

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In...

Primates play an important role in ecosystem functioning and offer critical insights into human evolution, biology, behavior, and emerging infectious diseases. There are 26 primate species in the Atlantic Forests of South America, 19 of them endemic. We compiled a dataset of 5,472 georeferenced locations of 26 native and 1 introduced primate specie...
