Odontogenic abscesses in rhesus macaques ( Macaca mulatta ) of Cayo Santiago
OBJECTIVES: Odontogenic abscesses are one of the most common dental diseases causing maxillofacial skeletal lesions. They affect the individual's ability to maintain the dental structures necessary to obtain adequate nutrition for survival and reproduction. In this study, the prevalence and pattern of odontogenic abscesses in relation to age, sex, matriline, and living periods were investigated in adult rhesus macaque skeletons of the free-rangin…
Free‐ranging Cayo Santiago rhesus monkeys ( Macaca mulatta )
This article describes the dental eruption patterns, dentition, and dental wear, including tooth loss and breakage, of the free-ranging population of rhesus monkeys (Macaca mulatta) on Cayo Santiago (CS), Puerto Rico, ranging from 24 hr to 25 years old. Of the 694 monkeys on the island in the year 1985, 688 (99.1%; 366 males, 322 females) were captured and the dentition of 685 subjects (98.7% of the total population; 366 males, 319 females) was e…
A 75‐year pictorial history of the Cayo Santiago rhesus monkey colony
This article presents a pictorial history of the free-ranging colony of rhesus monkeys (Macaca mulatta) on Cayo Santiago, Puerto Rico, in commemoration of the 75th anniversary of its establishment by Clarence R. Carpenter in December 1938. It is based on a presentation made by the authors at the symposium, Cayo Santiago: 75 Years of Leadership in Translational Research, held at the 36th Annual Meeting of the American Society of Primatologists in …
Discovery of a secular trend in Cayo Santiago macaque reproduction
Reproductive synchrony and the consequent clustering of births are hypothesized to be regulated by seasonal changes in rainfall and food availability. Such climate-related seasonality is, however, questionable in tropical populations occupying temporally invariant habitats year round. Using the long-term data of the Cayo Santiago rhesus macaques from 1973 to 2013, this study distinguishes synchrony (a greater than chance clustering of births) fro…

Long‐term effects of castration on the skeleton of male rhesus monkeys ( Macaca mulatta )
While osteopenia (OPE) and osteoporosis (OPO) have been studied in various species of aging nonhuman primates and extensively in ovariectomized rhesus and cynomolgus macaques, there is virtually no information on the effects of castration on the skeleton of male nonhuman primates. Most information on castrated male primates comes from a few studies on the skeletons of eunuchs. This report used a subset of the Caribbean Primate Research Center's (…
Managing the Cayo Santiago rhesus macaque population
Cayo Santiago is the oldest continuously operating free-ranging rhesus monkey colony in the world. Population control of this colony has historically been carried out by periodic live capture and removal of animals. However, the effect of such a strategy on the size, growth rate, age structure, and sex ratio of the population has not been analyzed. This study reviews past removal data and uses a population projection model to simulate the effects…
Genetic studies on the Cayo Santiago rhesus macaques
Genetic studies not only contribute substantially to our current understanding of the natural variation in behavior and health in many species, they also provide the basis of numerous in vivo models of human traits. Despite the many challenges posed by the high level of biological and social complexity, a long lifespan and difficult access in the field, genetic studies of primates are particularly rewarding because of the close evolutionary relat…
The mandibles of castrated male rhesus macaques ( M acaca mulatta )
OBJECTIVES: The objectives of this study were to evaluate the long-term effects of orchidectomy and low testosterone on the craniofaciodental development and maintenance of skeletal and oral health in rhesus macaques. MATERIALS AND METHODS: Mandibles of four castrated and intact age-matched male rhesus monkeys (Macaca mulatta) from Cayo Santiago were compared for mandibular morphology and teeth, abnormalities, pathology, and cortical bone thickne…
Long‐term effects of tetanus toxoid inoculation on the demography and life expectancy of the Cayo Santiago rhesus macaques
Tetanus was a major cause of mortality in the free-ranging population of rhesus monkeys on Cayo Santiago prior to 1985 when the entire colony was given its first dose of tetanus toxoid. The immediate reduction in mortality that followed tetanus toxoid inoculation (TTI) has been documented, but the long-term demographic effects of eliminating tetanus infections have not. This study uses the Cayo Santiago demographic database to construct comparati…
Demographic variability and density‐dependent dynamics of a free‐ranging rhesus macaque population
Density-dependence is hypothesized as the major mechanism of population regulation. However, the lack of long-term demographic data has hampered the use of density-dependent models in nonhuman primates. In this study, we make use of the long-term demographic data from Cayo Santiago's rhesus macaques to parameterize and analyze both a density-independent and a density-dependent population matrix model, and compare their projections with the observ…
Spontaneous Osteonecrosis of the Knee in Macaca mulatta
Tetanus antibody titers and duration of immunity to clinical tetanus infections in free‐ranging rhesus monkeys ( Macaca mulatta )
Prior to 1985 tetanus was a major cause of mortality in the free‐ranging colony of rhesus monkeys on Cayo Santiago, accounting for almost a quarter of annual deaths. In 1985 and 1986 all animals (except infants) received primary and booster doses, respectively, of tetanus toxoid. In subsequent years primary immunizations were given to all yearlings, and boosters were administered to all 2‐year‐old animals during the annual capture of the colony. …
Free‐ranging Cayo Santiago rhesus monkeys ( Macaca mulatta )
This paper presents comprehensive baseline data on body size and proportion of 661 (315 male, 346 female) free‐ranging Cayo Santiago rhesus monkeys ( Macaca mulatta ) ranging in age from 24 hours to 25 years. All animals were born and raised in the free‐ranging colony on Cayo Santiago, and exact ages were known for all. Tabular data from this cross‐sectional study are provided to enable comparisons with data from laboratory, wild, and other capti…
Free‐ranging Cayo Santiago rhesus monkeys ( Macaca mulatta )
Recent studies on the effects of caging on joint mobility and the correlations between joint mobility and use of the extremities have pointed out the need for baseline values that are readily available in the literature. This report provides normative data on the passive mobility of the major joints of free‐ranging Cayo Santiago rhesus monkeys ( Macaca mulatta ). The sample in this cross‐sectional study is large (661 animals including 315 males, …
