The knowledge about interactions between predators and prey is essential for understanding the natural history of animals, especially snakes, which are cryptic organisms that are difficult to visualize in the wild. This article reports on the predation of lizards, frogs, bats and venomous snakes by the snake Philodryas nattereri, evidencing its...

The Brazilian Caatinga has already lost extensive areas of original vegetation, thus it becomes imperative to perform fauna inventories within this region to fill geographical sampling gaps. Herein, we present a taxonomic list of the herpetofauna of a mountain chain located in the central zone of Rio Grande do Norte (RN) state whose region includes...

The spot-backed puffbird, Nystalus maculatus, is a diurnal bird found in several open to semi-open habitats, ranging from semiarid Caatinga to semihumid woodland. Its diet consists mainly of arthropods, including caterpillars, spiders, and scorpions. Occasional consumption of vertebrates such as lizards, snakes, and juvenile birds is also reported....

Displacement occurs during the movement of an organism and can be defined as a change in spatial position, being influenced by biotic and abiotic factors. Measuring the displacement of organ- isms within their home range is relevant for understanding their use of space and can reveal possible causes and consequences of their movements. During part...

The most heterogeneous environments have a larger variety of microhabitats, resulting in a greater richness and abundance of species. Lizards occur in the most varied types of habitats and microhabitats, being strongly influenced by environmental factors, such as temperature. This study aimed to analyze the influence of environmental factors on the...

Adenomera andreae and A. hylaedactyla are two widespread Amazonian frogs that have been traditionally distinguished from each other by the use of different habitats, toe tip development, and more recently through advertisement calls. Yet, taxonomic identification of these species has always been challenging. Herein we undertake a review of type spe...

We describe a new Amazonian species of Adenomera that corresponds to one of the acoustic signals and morphs from Tambopata National Reserve (Adenomera ‘‘Forest Call I’’) and to a confirmed candidate species (Adenomera sp. E) in the most recently published phylogeny for the genus. The new species is distinguished from all 19 described congeners by i...

Data on reproduction, sexual dimorphism, and the diet of Ceratophrys joazeirensis, the only species of the genus that occurs in the Brazilian semiarid Caatinga Biome, are presented. Anurans were obser...

Background Traditionally, the evolution of terrestrial reproduction in anurans from ancestors that bred in water has been accepted in the literature. Still, the existence of intermediate stages of water dependency, such as species that lay eggs close to water (e.g., in burrows) instead of in bodies of water, supports the hypothesis of an ordered an...
