Abstract: | We studied the monkeys inhabiting Bacan Island on the Maluku Archipelago, Indonesia. We compared them morphologically with
Sulawesi black macaques (Macaca nigra).We also assessed their distribution on the island and on neighboring islands and the influence of human activity on them.
We found that the Bacan black macaques are essentially similar to Sulawesi macaques; the variations in each locality are comparable.
The monkeys probably inhabit the whole island or, at least, the lower forest thereon. Human activities — cultivation, logging,
catching and killing monkeys — have not much affected their population. Thus they constitute a good stock of Macaca nigra,though the main population in Sulawesi is endangered. |
