Spider monkey home ranges: A comparison of radio telemetry and direct observation
(American Journal of Primatology, 1988-01-01)
The ranging patterns of two male and five female spider monkeys (Ateles geoffroyi) were studied with the use of radio telemetry in Santa Rosa National Park, Costa Rica. The average size of a spider monkey home range was ...
Plasma lipoproteins of free-ranging howling monkeys (Alouatta palliata).
(Comp Biochem Physiol B, 1987)
1. Plasma lipids and lipoproteins of free-ranging howling monkeys from Costa Rica (Alouatta palliata), aged 5 months to 23 years, were characterized. 2. High density lipoproteins were lipid-rich, similar to HDL2 of human ...
The impact of cropping on wild populations of Saguinus mystax and Saguinus fuscicollis in Peru
(American Journal of Primatology, 1984-01-01)
A transect census technique was used to estimate the population densities of Saguinus mystax and Saguinus fuscicollis at two sites in Peru. Cropping of these two species had occurred five years before the census at one site ...
Food choice from endemic North Carolina tree species by captive prosimians (Lemur fulvus)
(American Journal of Primatology, 1983-01-01)
Seven captive‐born lemurs (Lemur fulvus) at the Duke University Primate Center were presented with leaves of different maturity from five species of North Carolina trees. The animals demonstrated three distinct behaviors ...
Sexual selection and canine dimorphism in New World monkeys.
(Am J Phys Anthropol, 1988-11)
Social and ecological factors are important in shaping sexual dimorphism in Anthropoidea, but there is also a tendency for body-size dimorphism and canine dimorphism to increase with increased body size (Rensch's rule) (Rensch: ...
The impact of plant secondary compounds on primate feeding behavior
(American Journal of Physical Anthropology, 1982-01-01)
The recent literature on plant secondary compounds and their influence on primate feeding behavior is reviewed. Many studies of nonhuman primates document the extreme selectivity that primates, particularly herbivorous species, ...
Consumption of cyanogenic bamboo by a newly discovered species of bamboo lemur
(American Journal of Primatology, 1989-01-01)
Three species of bamboo‐eating lemurs were found to be sympatric in the southeastern rain forests of Madagascar. Sympatric species generally differ in habitat utilization or diet, but these three closely related bamboo lemurs ...
Reproduction and population growth in free-ranging mantled howling monkeys.
(Am J Phys Anthropol, 1980-07)
Free-ranging mantled howling monkey (Alouatta palliata Gray) females experienced a regular estrus cycle averaging 16.3 days, demonstrated sexual skin changes, and participated in multiple matings before becoming pregnant. ...
Meat eating and predation in captive‐born semi‐free‐ranging Lemur fulvus and caged Lemur macaco
(Zoo Biology, 1985-01-01)
A group of brown lemurs, Lemur fulvus, and a group of black lemurs, Lemur macaco, at the Duke University Center for the Study of Primate Biology and History have been observed to capture and eat birds and lizards. Although ...
