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.

It is a great honor to be asked to introduce this exciting new volume, having been heavily involved in the first comprehensive synthesis in the early 1980s. Gibbons are the most enthralling of primates. On the one hand, they are the most appealing animals, with their upright posture and body shape, facial markings, dramatic arm-swinging locomotion and suspensory postures, and devastating duets; on the other hand, the small apes are the most diverse, hence biologically valuable and informative, of our closest relatives. It is hard for me to believe that it is 40 years to the month since I first set foot on the Malay Peninsula to start my doctoral study of the siamang. I am very proud to have followed in the footsteps of the great pioneer of primate field study, Clarence Ray Carpenter (CR or Ray, who I was fortunate to meet twice, in Pennsylvania and in Zurich), first in Central America (in 1967) and then in Southeast Asia. It is 75 years since he studied howler monkeys on Barro Colorado Island in the Panama Canal Zone. It is 70 years since he studied the white-handed gibbon in Thailand.

Applies an ethnographic perspective to the study of primatesPrimate Ethnographies, 1/e is a collection of first-person accounts of immersive field studies of primates, people, and institutions, revealing the wide spectrum of primate science (primatology). Essays cover such primates as lemurs, New World monkeys, Old World monkeys, and apes. Readers experience the excitement of discovery and the challenges of primate field research. Primate Ethnographies can be used as a textbook or a companion reader.
