Ecological constraints on group size: an analysis of spider monkey and chimpanzee subgroups
The social organization of spider monkeys (Ateles geoffroyi) and chimpanzees (Pan troglodytes) appear remarkably similar. In this paper, field studies of these two species were used to (1) test aExpand

Estimators of Fruit Abundance of Tropical Trees1
Many types of biological studies require the estimation of food abundance in tropical forests, and a variety of methods have been used to estimate this parameter. Here we compare the accuracy andExpand

Seed dispersal by forest chimpanzees in Uganda
The role of chimpanzees (Pan troglodytes) as seed dispersers in the Kibale Forest Reserve of western Uganda was assessed by analysing 1849 dung samples from two chimpanzee communities and byExpand

A long-term evaluation of fruiting phenology: importance of climate change
Within the last decade the study of phenology has taken on new importance because of its contribution to climate-change research. However, phenology data sets spanning many years are rare in theExpand

Constraints on Group Size in Red Colobus and Red-tailed Guenons: Examining the Generality of the Ecological Constraints Model
The ecological constraints model proposes that an increase in group size will increase intragroup feeding competition and thereby constrain group size. Although this model has received wideExpand

Indices of Habitat-wide Fruit Abundance in Tropical Forests1
The assessment of fruit abundance is critical for studies of frugivore ecology. A variety of methods have been used to estimate habitat-wide fruit abundance. However, since the methods have not beenExpand

Forest Regeneration in Logged and Unlogged Forests of Kibale National Park, Uganda
Processes of forest regeneration in two unlogged areas and in three areas that were logged nearly 25 years ago were quantified in Kibale National Park, Uganda. For forests to recover from logging,Expand
