A cardinal measure of competitive ability in Barbary macaque males (Macaca sylvanus)
Cardinal scores of individual competitive ability allow us to quantify the magnitude of the difference between the competitive ability of any two individuals. However, they have rarely been used in animal behaviour because most researchers were mainly interested in ordinal ranking. In this paper, we validated the normalized David's score (David H. A., Biometrika 74, 1987, 432; de Vries H., Stev...
متن کاملWest Nile Virus Encephalitis in a Barbary Macaque (Macaca sylvanus)
An aged Barbary ape (Macaca sylvanus) at the Toronto Zoo became infected with naturally acquired West Nile virus encephalitis that caused neurologic signs, which, associated with other medical problems, led to euthanasia. The diagnosis was based on immunohistochemical assay of brain lesions, reverse transcriptase-polymerase chain reaction, and virus isolation.

متن کاملThe 'anatomy of disturbance' - a study of anthropic disturbance on Barbary macaque (Macaca sylvanus) troops in the Middle Atlas, Morocco
The endangered Barbary macaque (Macaca sylvanus) is the only macaque found wild outside of Asia. Its population has declined by over 50% in the last 23 years with the main threats including habitat loss through logging, overgrazing by livestock, illegal trade and developing negative effects of tourism. The last refuge of this species is in the Middle Atlas Mountains, Morocco. This refuge is bec...
متن کاملMaqFACS (Macaque Facial Action Coding System) can be used to document facial movements in Barbary macaques (Macaca sylvanus)
Human and non-human primates exhibit facial movements or displays to communicate with one another. The evolution of form and function of those displays could be better understood through multispecies comparisons. Anatomically based coding systems (Facial Action Coding Systems: FACS) are developed to enable such comparisons because they are standardized and systematic and aid identification of h...
