Indonesian Primates

Indonesia possesses the second largest primate population in the world, with over 33 different primate species. Although Brazil possesses more primate species, Indonesia outranks it in terms of its diversity of primates, ranging from prosimians (slow lorises and tarsiers), to a multitude of Old World Monkey species (macaques, langurs, proboscis moneys) to lesser apes (siamangs, gibbons) and great apes (orangutans). The primates of Indonesia are distributed throughout the archipelago.

Partly in response to the number of primates distributed throughout the Indonesian archipelago, Indonesia is classified as the home of two biodiversity hotspots (Wallacea and Sundaland). In order to be classified as a hotspot, an area must have a large proportion of endemic species coupled with a high degree of threat including having lost more than 70% of its original habitat. Two areas within Indonesia meet these criteria. The tremendous diversity of primates in Indonesia, in conjunction with the conservation issues facing the primates of this region, created a need for this volume.

Edited by two internationally renowned primatologists, this new text synthesizes current research on the primates of Indonesia, which include apes, monkeys, and prosimians. It is published at a crucial time as anxiety over the fate of the Indonesian primate population is rising. One study concluded that more than 70% of Asian primate species are threatened with extinction, while 84% of the dozens of Indonesian primate species are threatened. In this volume, the common thread of diversity is inextricably linked to the theme of conservation.

Contributed by key researchers from around the world, the volume's chapters demonstrate the sheer variety in Indonesian primates, ranging from Nekaris and Munds' study of using slow loris facial variation to distinguish species to Delgado's discussion of communication patterns among orangutans. The book's first section contains chapters on the endangered orangutans and gibbons. The orangutan, in its Sumatran and Bornean forms, is the only Asian great ape; yet in Borneo, Sugardito and Adhikerana nest densities are severely threatened by logging activity, especially at national park boundaries. The authors highlight the effectiveness of community-based patrolling as a protective measure is becoming an increasingly effective means of protecting orangutans. The second section of the text examines the diversity of monkeys in Indonesia, with each author in turn stressing the importance of conservation. Yorzinski uses the critically endangered pig-tailed langur of the Indonesian Mentawai Islands to demonstrate how isolated island primates react to predation pressure, while further chapters explore the relationship between vegetation and primate densities, habitat quality and its degradation, and human--simian interaction. A further section looks at the region's prosimians and notes that the taxonomic diversity is only recently being explored. The cryptic/nocturnal nature of these primates makes their conservation status even more uncertain.

Sharon Gursky-Doyen is an associate professor of anthropology at Texas A&M University. She received her BA from Hartwick College, her MS from the University of New Mexico, and her Ph.D. from the State University of New York at Stony Brook. She has been studying Sulawesi tarsiers since 1994. Her present research is centered on understanding the effects of altitude on the recently re-discovered pygmy tarsiers. She is the author of numerous scientific publications including The Spectral Tarsier, (Prentice Hall 2007); Primate Anti-Predator Strategies (coedited with Anna Nekaris, Springer 2007) as well as Tarsiers: Past, Present and Future (co-edited with Patricia Wright and Elwyn Simons, Rutgers University Press, 2003).

He has published 8 books on Indonesian Biodiversity and more than 90 articles in international journals. His books include: Panduan Lapangan Primata Indonesia (Field Guide of Indonesia Primates), Conservation Biology and Saving Indonesia's Nature. The latter two books are among the best-selling environment books in Indonesia.
