logged forest, acacia plantation and oil palm plantation) in Sabah, Malaysia was
investigated using three different methods based on habitat levels (Winkler
sampling, flight-interception-trapping and mist-blowing). The overall diversity
was extremely high, with 1711 species recorded from only 8028 individuals and 81
families (115 family and subfamily groups). Different degrees of environmental
changes had varying effects on the beetle species richness and abundance, with oil
palm plantation assemblage being most severely affected, followed by acacia
plantation and then logged forest. A few species became numerically dominant in
the oil palm plantation. In terms of beetle species composition, the acacia fauna
showed much similarity with the logged forest fauna, and the oil palm fauna was
very different from the rest. The effects of environmental variables (number of
plant species, sapling and tree densities, amount of leaf litter, ground cover, canopy
cover, soil pH and compaction) on the beetle assemblage were also investigated.
Leaf litter correlated with species richness, abundance and composition of
subterranean beetles. Plant species richness, tree and sapling densities correlated
with species richness, abundance and composition of understorey beetles while
ground cover correlated only with the species richness and abundance of these
beetles. Canopy cover correlated only with arboreal beetles. In trophic structure,
predators represented more than 40\% of the species and individuals.
Environmental changes affected the trophic structure with proportionally more
herbivores (abundance) but fewer predators (species richness and abundance) in
the oil palm plantation. Biodiversity, conservation and practical aspects of pest
management were also highlighted in this study.}, keywords = {Rhabdoscelus maculatus}, url = {http://journals.cambridge.org/download.php?file=\%2FBER\%2FBER90_06\%2FS0007485300000602a.pdf\&code=2c28f02ea5036aab417e3dfa463249ff}, author = {Chung, A.
