Chivers, D. J., 1989. Protected habitats in prospering urban I was told that this monkey was spotted eating rubber leaves at the rubber tree. This added complexity of analysis revealed that, although the diets of a hornbill and a primate species may have as many as 36 plant species in common, actual dietary overlap is low. We found that wild Southern pigtailed macaques enter oil pal, Assessing conservation issues for captive and wild Malaysian primates, Small mammals are often notoriously cryptic, especially arboreal nocturnal species. The dusky leaf monkey is one of two monkeys that can be found on Langkawi. ), BiopoliLcs: The BioEnvironment. Other foods they eat include shoots, seedlings, fruit (especially if unripe) and flowers. So far there has been no detailed long-term study on the biology and behaviour of these primates, especially on the influence of human disturbances on their acitivy patterns and diet.

Primates are effective seed dispersers but for many Malaysian species we still lack information about their feeding ecology and effectiveness as seed dispersers. As you might expect, the Dusky Leaf Monkey loves the trees. If primates and hornbills consume the same fruit species, they may be redundant in their roles as seed dispersers, and the loss of one of these taxa may be compensated for by the other. Diet. Dusky leaf monkeys are herbivores (folivores), they generally feed upon young leaves, fruits, shoots and seedlings. The Crab-eating Macaque is also be seen on the island.
