This book explores how seasonal variation in resource abundance might have driven primate and human evolution.

The emergence of the genus Homo is widely linked to the colonization of 'new' highly seasonal savannah habitats. However, until recently, our understanding of the possible impact of seasonality on this shift has been limited because we have little general knowledge of how seasonality affects the lives of primates. This book documents the extent of seasonality in food abundance in tropical woody vegetation, and then presents systematic analyses of the impact of seasonality in food supply on the behavioural ecology of non-human primates. Syntheses in this volume then produce broad generalizations concerning the impact of seasonality on behavioural ecology and reproduction in both human and non-human primates, and apply these insights to primate and human evolution. Written for graduate students and researchers in biological anthropology and behavioural ecology, this is an absorbing account of how seasonality may have affected an important episode in our own evolution.

A ground breaking study of primates that live in flooded habitats around the world.

The basic goal of the volume is to compile the most up to date research on how high altitude affects the behavior, ecology, evolution and conservation status of primates, especially in comparison to lowland populations. Historically, the majority of primate studies have focused on lowland populations. However, as the lowlands have been disappearing, more and more primatologists have begun studying populations located in higher altitudes. High altitude populations are important not only because of their uniqueness, but also because they highlight the range of primate adaptability and the complex variables that are involved in primate evolution. These populations are good examples of how geographic scales result in diversification and/or speciation. Yet, there have been very few papers addressing how this high altitude environment affects the behavior, ecology, and conservation status of these primates. ​

Comprehensive and unique volume exploring the differences and similarities between primate communities worldwide.

Methodologies as applied to recent primate research that will provide new approaches to comparative research.

Primatologists have long viewed small fruiting trees, like figs, as the reason for gibbons� territorial and monogamous behavior. However, at Khao Yai National Park in Thailand where gibbons are prevalent, figs are one of the largest trees in the forest. In this long-term field study, Bartlett takes up this apparent contradiction, and follows gibbons as their major food sources wax and wane over time.This is an important reference on gibbons and the study of small apes which provides a thorough, expansive coverage of the relationship between fruit abundance and diet, range use, and intergroup interactions in Gibbon apes. The Gibbons of Khao Yai: Seasonal Variation in Behavior and Ecology provides an essential resource for students conducting research in this field.
