The forests of southeastern Amazonia are highly threatened by disturbances such as fragmentation, understory fires, and extreme climatic events. Large‐bodied frugivores such as the lowland tapir (Tapirus terrestris) have the potential to offset this process, supporting natural forest regeneration by dispersing a variety of seeds over long distances to disturbed forests. However, we know little about their effectiveness as seed dispersers in degraded forest landscapes. Here, we investigate the seed dispersal function of lowland tapirs in Amazonian forests subject to a range of human (fire and fragmentation) and natural (extreme droughts and windstorms) disturbances, using a combination of field observations, camera traps, and light detection and ranging (LiDAR) data.

O Pronaf se tornou a principal política de apoio à agricultura familiar, a partir da qual outras políticas e programas foram elaborados de forma a integrar as ações governamentais para este segmento social - nos últimos 20 anos, foram investidos cerca de R$ 160 bilhões no Brasil. Mas é preciso repensar sua implementação considerando seu potencial como estímulo ao desenvolvimento sustentável.

Flies of the genus Apocephalus are common parasites of worker ants. Although the mechanisms used by parasitic flies to find their host are not well understood, olfactory cues have been suggested as the mechanism for host location, especially when the host ant is...
