This text contains selected presentations on lemurs made at the 17th IPS Congress in 1998. The chapters highlight new developments in lemur research, touching several important fields from conservation to theoretical aspects of behavioral ecology, as well as nutrition and public education.

This book is a truly international collaboration, with editors based on four con- nents and first authors from Canada, France, Japan, Madagascar, the United Kingdom, and the United States. Clearly, there is something attractive about studying Lemur catta, the ringtailed lemur. Perhaps it is the lemurs themselves! Why study ringtailed lemurs? Because lemurs are a separate radiation of p- mates from the monkeys, apes, and humans. Because ringtails live in the largest social groups of any known lemur and therefore offer the closest comparison with other social primates, including ourselves. And also because ringtails have become the flagship species of Madagascar. Some 70 species or subspecies of lemurs inhabit Madagascar. Each kind has its own fascinating story, but ringtails are the ones that everyone thinks they know. That black-and-white tail adorns tourist brochures and school notebooks and banknotes. All the same, after 40 years of field study, we don’t know nearly enough. In this book, we make a first estimate on how many might be alive today, but we do not know how many ri- tailed lemurs and how many southern forests will survive. This book explores part of what we do know. Its four sections are (I) Distribution: Ringtailed Lemurs in Madagascar, (II) Ringtails and Their Forests: Feeding and Ranging Behavior, (III) Social Behavior Within and Between Troops, and finally (IV) Health and Disease. Of course, all these issues are int- related.

Over the course of the past decade, there has been an enormous augmentation in the amount of information available on the lemurs of Madagascar. These advances are closely coupled with an increase in the number of national and international researchers working on these animals. As a result, Madagascar has emerged as one of the principal sites of primatological studies in the world. Furthermore, the conserva­ tion community has a massive interest in the preservation of the natural habitats of the island, and lemurs serve as one of the symbols of this cause. Between 10 and 14 August 1998, the XVIIth International Primatology Society (IPS) Congress was held in Antananarivo, Madagascar. For a country that about a decade ago was largely closed to foreign visitors, this Congress constituted a massive event for the Malagasy scientific community and was assisted by about 550 primatolo­ gists from 35 different countries. Naturally, given the venue and context of the Con­ gress, many of the presentations dealt with lemurs and covered a very wide breadth of subjects.
