Population dynamics and ranging behaviours of provisioned silvered langur (Trachypithecus cristatus) in Peninsular Malaysia
Tourists are attracted to the Bukit Melawati Kuala Selangor (BMKS) of Peninsular Malaysia, a small hill park, for both its status as a historical site and the free-ranging silvered langurs (Trachypithecus cristatus) that come for provisioning. We assessed the population trends and group sizes of T....
