Habitat Utilization by Long-Tailed Monkeys (Macaca fascicularis) in Gunung Palung National Park as a Biology Learning Resource

Daily Activity Budget of Long-tailed Macaques (Macaca fascicularis) in Kuala Selangor Nature Park

Long-tailed macaques (Macaca fascicularis) are widely distributed animals around the world that require special attention from the research and management perspectives. Daily activity budget of M. fascicularis were studied near the Kuala Selangor Nature Park as one part of study on its behavior and ecology. The study location was based along the M. fascicularis trails starting from the ticket c...

Reproductive Seasonality of Myanmar Long-tailed Macaque (Macaca fascicularis aurea)

– The Myanmar long-tailed macaques (Macaca fascicularis aurea) are distributed to coastal regions in Myanmar, ranging from 10 ̊ to 21 ̊N. Reproductive pattern was studied on a troop of long-tailed macaque inhabiting the steep limestone-rock Bayin Nyi Naung Mountain (16 ̊ 58.2' N), in Southern part of Myanmar, where the climate is seasonal. Bayin Nyi Naung Mountain troop shows the reproductive seas...

No costly prosociality among related long-tailed macaques (Macaca fascicularis).

Altruism, benefiting another at a cost to the donor, may be achieved through prosocial behavior. Studies of nonhuman animals typically investigate prosocial behavior with paradigms in which the donor can choose to give a recipient a food item, and the choice does not affect the donor's reward (which is either present or absent). In such tasks, long-tailed macaques (Macaca fascicularis) show pro...

Are Montane Forests Demographic Sinks for Bornean White-bearded Gibbons Hylobates albibarbis?

I estimated habitat-specific population densities for a population of Bornean white-bearded gibbons Hylobates albibarbis inhabiting seven distinct forest types at Gunung Palung National Park, West Kalimantan, Indonesia. Population densities in montane forests (0.44 individuals/km2) were almost ten times lower than those in the next best habitat (upland granite forest; 4.2 individuals/km2) and f...
