| Research Abstract |
Roles of habitat divergence and conspecific density effects on maintenance of tree diversity of a Bornean forest were studied with a long-term forest dynamics plot and a field experiment. Based on the long-term dynamics data, we found an interacting effect between species' habitat and conspecific density on tree mortality rate. A reciprocal seedling planting field experiment revealed that there were complex interactions among species, conspecific density and soils in mortality and leaf herbivory of seedlings. This study suggested importance of the interacting effects between habitat and conspecific density in maintenance of tree diversity of tropical rain forests.
