O banco de dados inclui levantamentos aves em um fragmento Mata Atlântica (Floresta Ombrófila Densa Submontana) no centro-leste Santa Catarina, sul do Brasil, entre novembro 2019 e agosto 2020. Dados riqueza abundância foram obtidos por meio método contagem pontos escuta. Foram estabelecidas três trilhas, “habitats A, B C”, com distância 800 m, 400 m 200 da borda fragmento. Seis escuta distribu...

Male blue monkeys (Cercopithecus mitis stuhlmanni) of Budongo Forest, Uganda, produce two acoustically distinct alarm calls: hacks to crowned eagles (Stephanoaetus coronatus) and pyows to leopards (Panthera pardus) and a range of other disturbances. In playback experiments, males responded to leopard growls exclusively with a series of pyows and to eagle shrieks predominantly with hacks. Respon...

Several taxa that share similar ascomatal and ascospore characters occur in monotypic or small genera throughout the Sordariomycetidae with uncertain relationships based on their morphology. Taxa in the genera Duradens, Leptosporella, Linocarpon, and Rimaconus share similar morphologies of conical ascomata, carbonised peridia and elongate ascospores, while taxa in the genera Caudatispora, Eryth...

Many species of desert birds are relatively small (< 500 g), diurnally active ground dwellers that are naturally exposed to high ambient temperatures (T,) and low relative humidities (RH). Sandgrouse (Pteroclididae), being small birds (weighing between 200 and 400 g) having a relatively high standard metabolic rate (SMR), would have to possess an effective mechanism for dissipating heat. Spotte...

Background: A juvenile Crowned Eagle was tagged at its nest with a satellite transmitter. The Crowned Eagle (Harpyhaliaetus coronatus) is one of the most unknown raptor species from the American continent. Their current distribution ranges from central Brazil to central Argentina, with a total population of 350–1500 individuals across this large area, being thus largely fragmented. Results: Dur...

The species of the common shrew (Sorex araneus) group are morphologically very similar but exhibit high levels of karyotypic variation. Here we used genetic variation at 10 microsatellite markers in a data set of 212 individuals mostly sampled in the western Alps and composed of five karyotypic taxa (Sorex coronatus, Sorex antinorii and the S. araneus chromosome races Cordon, Bretolet and Vaud)...

Recent developments in metacommunity theory have raised awareness that processes occurring at regional scales might interfere with local dynamics and affect conditions for the local coexistence of competing species. Four main paradigms are recognized in this context (namely, neutral, patch-dynamics, species-sorting, and mass-effect), which differ according to the role assigned to ecological or ...
