THE POPULATION DISTRIBUTION OF PIG-TAILED MACAQUE (Macaca nemestrina) AND LONG-TAILED MACAQUE (Macaca fascicularis) IN WEST CENTRAL SUMATRA, INDONESIA

Abstract

Two macaque species, the Pig-tailed Macaque (Macaca nemestrina) and Long-tailed Macaque (Macaca fascicularis), occur sympatrically in and around the lowland and mountainous forests of the Barisan Range in the Kerinci-Seblat National Park in west-central Sumatra. We present and discuss line-transect data on the density, distribution and group size of the two macaques. M. fascicularis was the scarcer, found only in hill dipterocarp and lowland forests.
