Averting biodiversity collapse in tropical forest protected areas

William F. Laurance, +216 more
- 13 Sep 2012 - 
TL;DR: These findings suggest that tropical protected areas are often intimately linked ecologically to their surrounding habitats, and that a failure to stem broad-scale loss and degradation of such habitats could sharply increase the likelihood of serious biodiversity declines.
Journal ArticleDOI

Ecological constraints on group size : an analysis of spider monkey and chimpanzee subgroups

TL;DR: Field studies of spider monkeys and chimpanzees were used to test a model of ecological constraints on animal group size which suggests that group size is a function of travel costs and assess ecological and social factors underlying the social organization of these two species.
Journal ArticleDOI

Estimators of Fruit Abundance of Tropical Trees1

TL;DR: Diameter at breast height (DBH) was the most consistently accurate method and exhibited low levels of interobserver variability, while crown volume was neither precise nor accurate.
Journal ArticleDOI

Habitat alteration and the conservation of African primates: case study of Kibale National Park, Uganda.

TL;DR: Examination of patterns of primate abundance in areas of Kibale National Park, Uganda, that have been modified by different types and intensities of human activities, primarily commercial logging and agricultural clearing suggests that patterns of population change associated with disturbance are complex.
