Evidence that zoo visitors influence HPA activity in spider monkeys ( Ateles geoffroyii rufiventris ). (Special issue: Primates in zoos)
Contributor(s):: Davis, N., Schaffner, C. M., Smith, T. E.
There has been conflicting evidence about the impact of visitors on zoo animals. The present study was designed to increase understanding of visitor effect by assessing the relationship between visitor numbers and activity in the hypothalamic-pituitary-adrenal (HPA) axis. An enzyme-immunoassay...
Assessment of preference for grid-flooring and sawdust-flooring by captive-bred marmosets in free-standing cages
Contributor(s):: Hardy, A., Windle, C. P., Baker, H. F., Ridley, R. M.
Marmosets (Callithrix jacchus) in a captive breeding colony living in metal caging, with wooden shelves and perches, were assessed by video recording for the time spent on the floor of the cage when that floor was a wire grid above a sawdust-filled tray and when it had been changed to a...
Inter-group variation in abnormal behaviour in chimpanzees ( Pan troglodytes ) and rhesus macaques ( Macaca mulatta )
Contributor(s):: Hook, M. A., Lambeth, S. P., Perlman, J. E., Stavisky, R., Bloomsmith, M. A., Schapiro, S. J.
The present study was designed to explore whether abnormal behaviour patterns in captive chimpanzees and rhesus macaques can provide additional data relevant to the question of social transmission of behaviour in non-human primates. The degrees to which various abnormal behaviours were displayed...
Factors influencing hair loss among female captive rhesus macaques ( Macaca mulatta )
Contributor(s):: Beisner, B. A., Isbell, L. A.
Although rare among wild animals, hair loss is common among captive animals, which suggests that some aspect of the captive environment contributes to abnormal hair loss. Female rhesus macaques (Macaca mulatta) at the California National Primate Research Center (CNPRC) housed in outdoor...
Exploiting flavour preferences of common marmosets to increase palatability of a dry pellet diet
Contributor(s):: Caldwell, C. A., Watson, C. F. E., Morris, K. D.
Although commercially available complete diets exist for common marmosets, the animals' consumption of these diets (available in dry pellet form) is typically very low. Increasing consumption of the pellet diet could have positive consequences for the welfare of the marmosets as the pellets are...
Patterns of injury in zoo-housed spider monkeys: a problem with males?
Contributor(s):: Davis, N., Schaffner, C. M., Wehnelt, S.
Aggression among wild spider monkeys is most frequently reported to occur between the sexes, with adult males directing aggression towards adult females and the aggression is normally non-injurious. After two severe instances of aggression in the group of spider monkeys housed at Chester Zoo, we...
Interactions between visitors and Formosan macaques ( Macaca cyclopis ) at Shou-Shan Nature Park, Taiwan
Contributor(s):: Hsu, M. J., Kao, ChienChing, Agoramoorthy, G.
Ecotourism involving feeding wildlife has raised public attention and is a controversial issue, especially concerning nonhuman primates. Between July 2002 and April 2005, the behavior of monkeys and tourists was collected through scan samplings, focal samplings and behavior samplings at the...
Behavioral differences between provisioned and non-provisioned Barbary macaques ( Macaca sylvanus )
Contributor(s):: Unwin, T., Smith, A.
The majority of Gibraltar's Barbary macaques (Macaca sylvanus) are provided with fruit and vegetable rations to keep them in the nature reserve and away from town. Recent fissioning of one troop has created a vagrant group that is denied access to official feeding sites by other troops, and which...

Frequency of feeding enrichment and response of laboratory nonhuman primates to unfamiliar people
Contributor(s):: Baker, K. C., Springer, D. A.
Although environmental enhancement plans for nonhuman primates vary between facilities, feeding enrichment represents a component of most programs. As part of a facility's feeding enrichment program, offering hand-fed food items by trained staff provides an opportunity for positive human...
