Rotavirus Antibodies in Hanuman Langurs (Presbytis entellus)
Journal of Medical Primatology, 1982Serum samples from wild Hanuman langurs (Presbytis entellus) from Mysore State, India, were compared to samples from a laboratory colony from Davis, Calif., for antibodies to rotavirus, which is an important cause of gastroenteritis in mammals. Animals from the laboratory colony had a higher frequency and higher levels of antibody than wild animals. It

Determinants of female dispersal in Thomas langurs
American Journal of Primatology, 1997Female dispersal occurs in a number of primate species. It may be related to: avoidance of inbreeding, reduction in food competition, reduction of predation risk, or avoidance of infanticide in combination with mate choice. Female dispersal was studied for a 5-year period in a wild population of Thomas langurs (Presbytis thomasi) that lived in one-male

In the initial phase, during the extreme glaciation period in the Early Pleistocene Epoch, some ancient Javan langurs took the opportunity to emigrate ...

DISCRIMINATION LEARNING IN LANGURS AND RHESUS MONKEYS
Perceptual and Motor Skills, 1967To compare cognitive behavior, 4 langurs ( Presbytis entellus) and 6 rhesus monkeys (Macaca mulatta) were run on tests of visual patterns and object discriminations. Langurs were significantly superior to rhesus monkeys in both, which suggests a higher phylogenetic rank

Females, Male Competition and Gray Langur Troop Structure
Folia Primatologica, 1982During the course of an ongoing investigation of the effects of mother-infant separation on development in gray langur monkeys (Presbytis entellus), a series of 4 mothers of approximately 6-month-old infants were removed from their social groups and placed in a captive all-male group for 2-week periods.
