TL;DR: In this paper, a simulation study and empirical camera-trapping data were used to illustrate how ecological and sampling-related factors can bias relative abundance indices (RAI, number of records per trap effort), although these do not account for imperfect and variable detection.

TL;DR: Although the degree of forest disturbance and canopy gap size influenced terrestriality, orangutans were recorded on the ground as frequently in heavily degraded habitats as in primary forests, suggesting that terrestrial locomotion is part of the Bornean orangutan's natural behavioural repertoire to a much greater extent than previously thought.

TL;DR: The results suggest that human disturbance alters the species composition of the stingless bee community, and such changes in the bee community may affect the reproductive success of plants, and ultimately forest composition.

TL;DR: In this paper, the authors investigated the abundances of medium to large ground-dwelling vertebrates in a forest management unit in Borneo by camera trapping and found that no species showed a significant difference in MTR between the pre- and postharvested areas.

TL;DR: Fujita et al. as discussed by the authors presented a G-COE series on area studies in the Batu Biosphere Reserve in Riau, Indonesia, focusing on the area of Southeast Asian studies.
