Análise comportamental do urubu-de-cabeça-vermelha (Cathartes aura LINNAEUS, 1758) [PDF]
Os necrófagos formam um grupo funcional de grande importância nos ecossistemas, sendo os responsáveis diretos pela remoção de carcaças da natureza. Abutres e urubus são os únicos vertebrados que se alimentam quase que exclusivamente de carcaças, sendo ...

Preliminary effects of UAS angle of approach on escape responses of a large-bodied raptor
Animal responses to unoccupied aircraft systems (UAS) can be exploited to reduce human-wildlife conflicts. We investigated how same-level UAS approaches (0°) would be perceived by Turkey Vultures (Cathartes aura; “vultures”) compared to stoop approaches (

Energy transfer is fundamental to ecosystem processes, affecting productivity and community structure. Large aggregations of colonially breeding birds are known as nutrient sources through deposition of feces, but also may deposit large quantities of ...

Abstract Knowing about species interactions is essential for ecological research, conservation efforts, resource management, and maintaining healthy ecosystems, but many of these, such as reports of predation, may not always be published in easily located resources—if they are published at all.

Seed dormancy explains plant response to mass mortality events
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mass mortality events (MMEs) are large‐scale, rapid die‐offs resulting in extreme inputs of carrion biomass. Recent work demonstrates the effects of increasing carrion biomass on plant communities modulated by vertebrate scavengers and herbivores.
