Speciation mechanisms and coevolution at Malesian wet tropics (Sumatra)

在潮湿的马来热带地区，最多的物种共同生活，形成了一个热带雨林系统的复杂网络。植物的物种形成机制，以及传粉动物和植物之间的相互作用，很少有研究。我们在1987-1988年的研究，旨在对马来热带物种形成的认识作出贡献。本文对凤仙花的访花昆虫及其行为进行了研究，凤仙花属近缘种的生境分布和染色体数目;（2）各种形状猪笼草的笼内动物区系;（3）两种野蕉的生物学差异及传粉者。本文对乌鲁嘎杜特地区热带雨林动态分析研究中建立的6块永久林样地中约3,000株树木进行了胸径调查。

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.
