Multiple sirehood in free‐ranging twin rhesus macaques ( Macaca mulatta )
Rhesus macaque females regularly copulate with a number of partners, and produce a single offspring per reproductive cycle in over 99% of cases. We used genotyping of 10 STR markers to determine paternity in the Cayo Santiago population of rhesus macaques. About 1,500 monkeys have been analyzed to date, with their marker genotypes entered into a computerized database. These data enable us to report the first documented case in any cercopithecine …
Primigravidity, body weight, and costs of rearing first offspring in rhesus macaques
Body size is associated with menarche and ovarian function, but the relationship to first conception is rarely examined. We conducted a longitudinal investigation of rhesus macaques, Macaca mulatta, to determine the effect of differences in body weight on both the age at first conception and survivorship of first progeny. Young females who became pregnant weighed significantly more than peers who remained barren, with weight changes for females w…
Primigravidity, body weight, and costs of rearing first offspring in rhesus macaques
Metabolic abnormalities among free‐ranging Macaca mulatta on Cayo Santiago
Free‐ranging rhesus macaques ( Macaca mulatta ) were examined on the island of Cayo Santiago (CS), Puerto Rico, with intravenous glucose tolerance tests (IV‐GTTs). Results were compared to monkeys derived from the island, but subsequently housed in corrals or gang cages at Sabana Seca (SS). Glucose clearance was similar among CS and SS macaques (range 2.99 to 4.50%min); both CS and SS males had significantly greater fasting serum glucose levels (…
Parasites of free‐ranging Cayo Santiago macaques after 46 years of isolation
Three hundred and thirty seven Macaca mulatta from a population that had been isolated on a small island off the coast of Puerto Rico for 46 years were examined for parasites. Anatrichosoma cynamolgi (26%), Strongyloides fuelleborni (54%); Trichuris trichiura (23%); and Balantidium coli (2%) were detected. Toxoplasma antibodies were found in 10% of the sera examined. Milk was examined for Stronglyloides , and blood was examined for microfilariae …
Leptospiral agglutinins in the Cayo Santiago macaques
The colony of free‐ranging rhesus monkeys ( Macaca mulatta ) on Cayo Santiago, Puerto Rico, was surveyed for leptospiral agglutinins. Only 5 (3%) of 169 monkeys (25% of the population) were seropositive (titers of ⩾ 1:100). An additional 29 animals (17%) had titers ⩽1:50. The proportions of seropositive males and females were 22% and 18%, respectively, and twice as many adult as immature animals (32% vs. 15%) were positive. In most seropositive m…
Effect of tetanus toxoid inoculation on mortality in the Cayo Santiago macaque population
Tetanus was a major cause of mortality in the free‐ranging population of rhesus monkeys ( Macaca mulatta ) on Cayo Santiago. From 1977 to 1984 the mean (±1 SD) annual total mortality rate (excluding neonatal deaths within 48 h postpartum, abortions, and stillbirths) was 6.39% ± .94%, and the mean annual tetanus mortality rate was 1.33% ± .45%. Tetanus deaths accounted for 19.5% of the total mortality in the colony. In 1985, all monkeys on the isl…
Secondary sex ratio variation in the Cayo Santiago macaque population
Secondary sex ratios (SSR) were calculated from 1,385 offspring delivered by 372 females in the Cayo Santiago population of free‐ranging rhesus monkeys ( Macaca mulatta ) from 1976 through 1984. The SSR for the entire colony ranged from 0.86 to 1.46 males per female (combined total: 1.08), but no significant difference was observed (P > .05). SSR values were compared among the troops for each year. The SSR differed significantly among the six soc…
Carbohydrate impairment and insulin secretory abnormalities among Macaca mulatta from Cayo Santiago
Rhesus macaques ( Macaca mulatta ) from Cayo Santiago were examined for evidence of carbohydrate intolerance indicative of potential development of non‐insulin‐dependent diabetes mellitus (NIDDM). Monkeys 6 to >20 years from natal Groups J, M, and P, an AGED Group (all >20 years), and unrelated monkeys removed from the island in association with other groups (CAYO), were examined with intravenous glucose tolerance tests (iv‐GTT). Morphometric mea…
Climate and seasonal reproduction in the Cayo Santiago macaques
This paper reports the results of an eight‐year study of seasonal reproduction in the free‐ranging colony of rhesus monkeys on Cayo Santiago, Puerto Rico. There was a significant correlation between the start of the annual spring rainy season and the estimated median conception date (r = .94, p
The hemogram, serum biochemistry, and electrolyte profile of the free‐ranging Cayo Santiago rhesus macaques ( Macaca mulatta )
Sixty‐four male and 33 female free‐ranging rhesus monkeys ( Macaca mulatta ) from one of six social groups on the island of Cayo Santiago, Puerto Rico, were surveyed to establish normal values for the hemogram and serum biochemical and electrolytes for the colony. Mean values (± 1 SD) are reported by sex for each of three age groups (2–3, 4–9 and ≥ 10 years). All adult females (≥ 4 years) were pregnant. There were significant differences for a nu…
A fatal epizootic of undetermined etiology in new world monkeys
A peracute epizootic disease, strikingly characterized by profuse terminal hemorrhaging from the lungs, caused the deaths of 104 squirrel monkeys and 3 capuchin monkeys over a 22‐month period. The case fatality rate was 100%. The pulmonary hemorrhaging was often accompanied by pulmonary edema and congestion, interstitial pneumonia, and hydrothorax. Additional histologic lesions included interstitial nephritis, hepatitis and hepatic necrosis, adre…
Nasal and cutaneous anatrichosomiasis in the free‐ranging rhesus monkeys ( Macaca mulatta ) of Cayo Santiago
One hundred and twenty‐nine free‐ranging rhesus monkeys on the island of Cayo Santiago were surveyed for the nematode Anatrichosoma cutaneum . The purpose of the study was to determine the prevalence of the nasal and cutaneous forms of this parasite in untreated rhesus monkeys maintained in a seminatural subtropical environment. The average prevalence of the nasal form in the sampled Cayo Santiago macaques was 23.2%. Adults were more commoly effe…
A five‐year study of tetanus in the Cayo Santiago rhesus monkey colony
Tetanus is a major cause of death in the free‐ranging rhesus moonkey colony on the island of Cayo Santiago, Puerto Rico. During the five‐year period of observation (July 1, 1976 through June 30, 1981), the mean annual tetanus mortality rate (± 1 SD) was 1.74% (±0.15). The mean annual total mortality rate was 6.77% (±0.78). The tetanus mortality rate varied sigificantly (P Clostridium tetani toxin, thus confirming that tetanus is a nonimmunizing d…
