| Research Abstract |
To study the maintenance mechanism of biodiversity on Borneo Island, we conducted research in Merimbun Heritage Park, Mt. Kinabalu, Sabah, Betung Kerihun National Park, West Kalimantan, and Berau, East Kalimantan for 257 days. We made plots of 4ha in Brunei, 6-ha in Kalimantan, and 1.5ha for plant ecological study, and collected 2733 plant specimens. Lowland of Borneo Island is dominated by Dipterocarpaceae, but there are many kinds of Dipterocarpaceae forests. The species numbers of trees bigger than 4.8cm in DBH in 1-ha were ranged from ca 70 to 220, lowest in swamp, the second was riverbank forest, and forest on hill was most rich. The mechanism of coexistence was studied in congeneric species of Sterculiaceae, Meliaceae, and Palmae. Genetic diversity was studied in Licuala and Cyrtostachys of Palmae. The role of animals for seed dispersal was also studied.
