Speciation mechanisms and coevolution at Malesian wet tropics (Sumatra)

最多的物种共同生活在一起，形成了湿润的马来热带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与植物之间的相互作用几乎没有被研究过。我们1987-1988年的研究旨在促进对马来热带物种形成的认识。重点研究了凤仙花中的访花昆虫及其行为、凤仙花近缘种的生境划分和染色体数目、不同形状猪笼草中的动物区系以及两种野生香蕉(Musa)的生物学差异和传粉者。为了分析热带雨林的动态变化，我们在乌鲁加杜特地区建立了6个永久样地，对约3000株树木进行了胸径普查。

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.
