Research Overview

In Southeast Asian tropics, forest area is disappearing rapidly due to increasing plantations and it is resulting in severe decrease of biodiversity. It is said that most of the lowland primary forests have already been destroyed in this region. In order to conserve biodiversity, my study focuses on the remnant forests used by the communities in Borneo; where small forest patches remain within a landscape of shifting-cultivation and provide people with timbers and/or non-timber forest products such as rattan and fruits. I am trying to assess how much species diversity these forests contain and to investigate the conservation value of the forests in maintaining regional biodiversity.
I am also conducting empirical and theoretical studies on the mechanisms of maintenance of species diversity. I have studied the phenomena of “general flowering” which occurs only in the Southeast Asian lowland tropical forests and have been monitoring the flowering events in Borneo for more than 10 years.
