A total of 378 adult and juvenile rhesus macaques of both sexes were transferred from single- to isosexual pair-housing arrangements. The incidence of serious injury resulting from partner incompatibility was 0.8% during the first year after pair formation. It was concluded that pair-housing offers a safe option to address the animals' social needs in compliance with federal rules and professional standards

En captivité, le contrôle des naissances est primordial pour assurer la gestion des animaux. Cependant il soulève diverses questions. Les premières concernent la méthode employée et ses effets spécifiques sur l’individu, à savoir comment l’utilisation d’une contraception hormonale ou d’une stérilisation chirurgicale exerce un effet sur les hormones, le comportement et le bien-être d’un individu ou encore sur le groupe social tout entier. Les secondes s’apparentent davantage aux questions éthiques, au fait de priver ou non un individu de comportements parentaux, exprimés de manière naturelle en liberté. Au sein de systèmes sociaux complexes tels que les primates, ces questions sont essentielles pour comprendre les mécanismes façonnant les dynamiques sociales dans des conditions où la reproduction est contrôlée. Pour étudier ces questions, il est nécessaire de faire des relevés comportementaux et de prélever simultanément des échantillons biologiques pour étudier les profils hormonaux des individus. L’utilisation d’échantillons fécaux a l’avantage de pouvoir être utilisée à la fois en milieu captif et en milieu naturel et de ne pas nécessiter de contact direct avec l’animal, ce qui évite de le stresser. Cette étude avait pour but de vérifier si la méthode de dosage immuno-enzymatique (EIA), à partir d’échantillons fécaux, permet d’établir le profil hormonal de femelles macaque rhésus tubectomisées (i.e. ligature des trompes maintenant la fonction ovarienne) en dehors de la saison de reproduction et de vérifier s’il existe ou non une corrélation entre les variations hormonales et les comportements socio-sexuels observés en cette saison. L’étude s’est déroulée au zoo Planète Sauvage en France, où toutes les femelles du groupe en âge de se reproduire, ont été tubectomisées quelques mois auparavant, excepté celles déjà ovariectomisées. Des échantillons fécaux de 10 femelles tubectomisées, ainsi que des observations des comportements sexuels, agonistiques et affiliatifs ont été réalisées pendant 2 mois, via des focaux, des scans de proximité et des observations ad libitum. Des données morphologiques pouvant témoigner d’une période particulière du cycle ovarien ont également été relevées (saignements menstruels et coloration de la zone anogénitale). Les dosages immuno-enzymatiques ont permis de confirmer les profils irréguliers et anovulatoires des cycles ovariens des macaques rhésus, avec des concentrations basses en E1G et PdG en période de non-reproduction (printemps). Nous avons pu déterminer que la méthode de dosage EIA pouvait effectivement être utilisée sur des échantillons fécaux, lors de cette saison de non-reproduction peu documentée dans la littérature. Cependant des études en période de reproduction seront nécessaires pour valider totalement cette méthode. Nos résultats ont montré que les hormones stéroïdiennes, en particulier l’oestradiol, n’influent pas de manière significative sur les comportements sexuels des individus hors saison de reproduction. Nous avons également déterminé une absence de compétition sexuelle entre femelles à cette période, et dès lors peu d’influence des comportements sexuels sur les comportements sociaux, contrairement à ce qui est généralement observé en période de reproduction. Cependant, nous avons observé un effet très net du rang hiérarchique et des naissances sur les comportements sexuels, agonistiques et affiliatifs, notamment entre les femelles. Des études approfondies lors des prochaines années et en saison de reproduction seront nécessaires sur ce groupe de macaques, afin de déterminer si l’arrêt complet de la reproduction via l’approche par tubectomie a eu un effet sur la physiologie ou les comportements des individus, ainsi que sur l’organisation sociale du groupe. Il sera particulièrement intéressant de vérifier si l’absence de naissance aura un impact sur cette population.

Histopathology Atlas of Acute Radiation Syndrome and Delayed Effects in Rhesus Macaques: Kidney, Lung, Heart, Intestine and Mesenteric Lymph Node provides a thoroughly illustrated review of the tissue damage and reparative changes associated with standardized irradiation doses in rhesus macaques. In addition to time-sequenced, routinely stained histologic sections, the book presents results of numerous histochemical, immunohistochemical and chromogenic in-situ stains that provide insights into the pathogenesis of radiation-associated tissue injury and repair. This book is compiled and written by a board-certified veterinary pathologist with more than 40 years of experience in the interpretation of experimentally induced tissue alterations in laboratory animals.

For a wide spectrum of scientists from biomedical and dental researchers to primatologists and physical anthropologists, Emet Schneiderman offers the most accurate and up-to-date presentation of the normal growth of the lower facial skeleton in a primate species. His study is based on a sample of thirty-five captive rhesus monkeys, whose facial growth was traced over a ten-year period spanning from infancy to adulthood. The author identifies the relative contribution of various sites of growth, quantifies the relative roles of different types of development--such as appositional and condylar--and sheds light on several long-standing controversies as to how the primate face grows. Unlike many of the traditional cephalometric measurements, the ones included in this work were chosen to reflect the positional, dimensional, and localized remodeling changes that occur during ontogeny. Using a new statistical approach designed for longitudinal data, Schneiderman avoids the misleading information that has often resulted from older, cross-sectional statistical methods. This book serves as a foundation for future experimental and normal studies in the rhesus monkey and, from a methodological standpoint, as a general model for future longitudinal growth studies.Originally published in 1992.The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Judged by population size and distribution, homo sapiens are clearly the most successful primates. A close second, however, would be rhesus macaques, who have adapted to-and thrived in-such diverse environments as mountain forests, dry grasslands, and urban sprawl. Scientists have spent countless hours studying these opportunistic monkeys, but rhesus macaques have long been overshadowed in the public eye by the great apes, who, because of their greater intelligence, are naturally assumed to have more to teach us, both about other primates and about humans as well. Dario Maestripieri thinks it is high time we shelve that misperception, and with Macachiavellian Intelligence he gives rhesus macaques their rightful turn in the spotlight. The product of more than twenty years studying these fascinating creatures, Macachiavellian Intelligence caricatures a society that is as much human as monkey, with hierarchies and power struggles that would impress Machiavelli himself. High-status macaques, for instance, maintain their rank through deft uses of violence and manipulation, while altruism is almost unknown and relationships are perpetually subject to the cruel laws of the market. Throughout this eye-opening account, Maestripieri weds his thorough knowledge of macaque behavior to his abiding fascination with human society and motivations. The result is a book unlike any other, one that draws on economics as much as evolutionary biology, politics as much as primatology. Rife with unexpected connections and peppered with fascinating anecdotes, Macachiavellian Intelligence has as much to teach us about humans as it does about macaques, presenting a wry, rational, and wholly surprising view of our humanity as seen through the monkey in the mirror.
