| Research Abstract |
Many islands of various size comprise the tropical country, Indonesia. Among those islands, Kalimantan (Borneo) is three times of Honshu of Japan in size and the center of Sunda Land. It provides a living area for many non-human primates such as orangutan, gibbons, leaf-monkeys and macaques. The Asian team of Primate Research Institute, Kyoto University has been studying non-human primates in Southeast Asia since 1973. However, the field areas have been outside of this huge island. We though the filed work of 1996 was a preliminary study and included researchers of many scientific fields.
The first sub-team is consisted by Takenaka, Mouri, Hirai and Suryobroto, and collected morphological date and blood samples from gibbons and macaques of wide areas. We visited Pangkaran Bun, Balikpapan and Banjarmasin. The samples were over 80 heads and are now under analyzes of morphological examination, karyotypes and the nucleotide sequences of the cytochrome b gene of mitochondrial DNA.The second sub-team, Matsumura tried find out suitable fields in east Kalimantan and found out 1) crab-eating macaques (Macaca fascicularis) are easily accessible but pig-tailed macaques (M.nemestrina) are hard to observe. In contrast, Leaf-monkeys, probosis monkeys (Nasalis larvatus) and silver lutung (Trachypithecus cristatus) are not difficult to access in the forest near from rivers. The third sub-team, Fujita and Ueno examined the preference of macaques to the sense of taste and smell and found out some species difference in tolerance against bitterness and astringency. They also found a selective tool-use in macaques in different conditions. The fourth, Suzuki, continued observation of orangutan from the stand point of their sociality.
Based on these preliminary results, we are making further plan for studying non-human primates in Kalimantan to compare with those of the other islands.
