Getting from here to there may be simple for one individual. But as any parent, scout leader, or CEO knows, herding a whole troop in one direction is a lot more complicated. Who leads the group? Who decides where the group will travel, and using what information? How do they accomplish these tasks? "On the Move" addresses these questions, examining the social, cognitive and ecological processes that underlie patterns and strategies of group travel. Chapters discuss how factors such as group size, resource distribution and availability, the costs of travel, predation, social cohesion and cognitive skills affect how individuals as well as social groups exploit their environment. Most chapters focus on field studies of a wide range of human and nonhuman primate groups, from squirrel monkeys to Turkana pastoralists, but chapters covering group travel in hyenas, birds, dolphins and bees provide a broad taxonomic perspective and offer new insights into comparative questions, such as whether primates are unique in their ability to coordinate group-level activities.

The purpose of this volume is to present a comprehensive overview of recent advances in primate field research, ecology, and conservation biology in Mesoamerica. The overall goal of each contribution is to integrate newly collected field data with theoretical perspectives drawn from evolutionary biology, socioecology, biological anthropology, and conservation to identify how our current knowledge of primate behavior and ecology has moved beyond more traditional approaches. A corollary to this, and an important goal of the volume is to identify geographical regions and species for which we continue to lack sufficient information, to develop action plans for future research, and to identify areas for immediate conservation action. Despite many decades of primate research in Mesoamerica, much is still unknown concerning the basic ecology and behavior of these species, demography, current distribution, and conservation status of local populations, and the effectiveness of conservation policies on primate survivorship. Four major areas of research are the focus of the volume: Evolutionary Biology and Biogeography; Population Demography and Ecology; Behavior; and Conservation and Management Policies.

This will be the first time a volume will be compiled focusing on South American monkeys as models to address and test critical issues in the study of nonhuman primates. In addition, the volume will serve an important compliment to the book on Mesoamerican primates recently published in the series under the DIPR book series. The book will be of interest to a broad range of scientists in various disciplines, ranging from primatology, to animal behavior, animal ecology, conservation biology, veterinary science, animal husbandry, anthropology, and natural resource management. Moreover, although the volume will highlight South American primates, chapters will not simply review particular taxa or topics. Rather the focus of each chapter is to examine the nature and range of primate responses to changes in their ecological and social environments, and to use data on South American monkeys to address critical theoretical questions in the study of primate behavior, ecology, and conservation. Thus, we anticipate that the volume will be widely read by a broad range of students and researchers interested in prosimians, New World monkeys, Old World monkeys, apes, humans, as well as animal behavior and tropical biology.

This will be the first time a volume will be compiled focusing on South American monkeys as models to address and test critical issues in the study of nonhuman primates.

This collection of 29 papers grew out of a symposium entitled "Setting the Future Agenda for Neotropical Primates. " The symposium was held at the Department of Zoo­ logical Research, National Zoological Park, Washington D. C. , on February 26-27, 1994, and was sponsored by the Wenner-Gren Foundation for Anthropological Research, Smith­ sonian Institution, and Friends of the National Zoo. We put the symposium together with two objectives: to honor Warren G. Kinzey for his contributions to the growing field of platyrrhine studies and to provide researchers who work in the Neotropics with the oppor­ tunity to discuss recent developments, to identify areas of research that require additional study, and especially to help guide the next generation of researchers. The symposium provided the opportunity to recognize Warren as a mentor and col­ laborator to the contribution of the study of platyrrhines. Contributions to the book were expanded in order to provide a more comprehensive view of platyrrhine evolution and ecology, to emphasize the interdisciplinary nature of many of these studies, and to high­ light the central role that New World monkeys play in advancing primatology. If this vol­ ume were to require major revisions after just one more decade of research, that would be a fitting testament to Warren's enthusiasm and his drive to continually update the field with new ideas and methods. Tributes to Warren and a list of his publications have been published elsewhere (Norconk, 1994, 1996; Rosenberger 1994, 1995).

Howler monkeys (genus Alouatta) comprise 12 species of leaf-eating New World monkeys that range from southern Mexico through northern Argentina. This genus is the most widespread of any New World primate and can be found to inhabit a range of forest types from undisturbed rainforest to severely anthropogenically-impacted forest fragments. Although there have been many studies on individual species of howler monkeys, this book is the first comprehensive volume that places information on howler behavior and biology within a theoretical framework of ecological and social adaptability. This is the first of two companion volumes devoted to the genus Alouatta.This volume:·         Provides new and original empirical and theoretical research on howler monkeys·         Presents evolutionary and adaptive explanations for the ecological success of howler monkeys·          Examines howler behavior and ecology within a comparative frameworkThese goals are achieved in a collection of chapters written by a distinguished group of scientists on the evolutionary history, paleontology, taxonomy, genetics, morphology, physiology, and anatomy of howlers. The volume also contains chapters on howlers as vectors of infectious diseases, ethnoprimatology, and conservation.

This is the second of two volumes devoted to the genus Alouatta.This volume:·         Examines behavioral and physiological mechanisms that enable howler monkeys to exploit highly disturbed and fragmented habitats·         Presents models of howler monkey diet, social organization, and mating systems that can also inform researchers studying Old World colobines, apes, and other tropical mammalsThese goals are achieved in a collection of chapters written by a distinguished group of scientists on the feeding ecology, behavior, mating strategies, and management and conservation of howlers. This book also contains chapters on the howler microbiome, the concept of behavioral variability, sexual selection, and the role of primates in forest regeneration.
