| Research Abstract |
The highest number of species live together forming a comples web of the tropical rain forest system in wet Malesian tropics. The speciation mechanisms of plants, as well as the interactions between pollinator animals and plants, have been scarcely studied. Our research in 1987-1988 intended to contribute to the knowlege on the speciation in Malesian tropics. We paid our partricular attention to (1)the flower-visiting insects and their behaviour in impatiens spp., and habitat segrigation and chromosome numbers of related Impatiens species, (2)fauna trapped in pitchers of various shapes of Nepenthes spp., and (3)biological difference and pollinators of two wild bananas (Musa). we carried out dbh censuses of about 3,000 trees in six permanent forerst plot in ulugadut area which had been established by our earlier resarches for analize dynamics of tropical rain forest.
