Population survey of the Bengal slow loris, Nycticebus bengalensis, in Meghalaya, northeast India

摘要

The Bengal slow loris Nycticebus bengalensis is a nocturnal prosimian that inhabits the forests of northeastern India. As with many nocturnal prosimian species, little is known about its behavior or ecology; even less information is available on its distribution and population status in northeastern India. We conducted a survey of forest patches in the state of Meghalaya, in northeast India, in order to assess its distribution. A secondary aim of our study was to estimate the severity of threats that may affect the long-term survival of the slow loris in Meghalaya. We surveyed sixteen sites in six districts. Slow lorises were seen in only two sites; however, information obtained through secondary sources indicated that they were present in a number of other forest patches across the state. Many of the forests surveyed were severely affected by logging, poaching and forest fires; it is imperative that conservation measures, aimed at protecting existing forest patches, be implemented in order to ensure the long-term survival of the slow loris and other mammals in the state.
