The Effect of Droughts and Fires on Coleopteran Insects in Lowland Dipterocarp Forests in Bukit Soeharto,East Kalimantan
The lowland dipterocarp forest in Borneo is one of the most species-rich ecosystems in the world (e.g., Whitmore 1984). The dipterocarp ecosystem is home to hundreds of thousands of animal and plant species, which form an intrinsic network of interactions (Schulte 1996). There are thought to be a large number of species of insects living in the lowland dipterocarp forest. We have been investigating the insect profiles in the lowland dipterocarp forest in Bukit Soeharto Education Forest (BSEF) of Mulawarman University, East Kalimantan, and have confirmed the species richness of insects in the lowland dipterocarp forest. For example, more than 550 species of the family Cerambycidae (Longicorn beetles) were found in a restricted area (ca. 1000 ha) of our study site in 1998 (Makihara 1999). This number is more than half of the total number of cerambycid species in all of North America (Linsley and Chemsak 1997).
