Assessment of the bioindicator values of flying insects at a higher taxonomic level for different logging schemes in the lowland tropical rain forests of Deramakot, Sabah, Malaysia Assessment of the bioindicator values of flying insects at a higher taxonomic level for different logging schemes in the lowland tropical rain forests of Deramakot, Sabah, Malaysia 阿久津, 公祐 アクツ, コウスケ Khen, Chey Vun Akutsu, Kosuke Khen, Chey Vun © 2006 by DIWPA application/pdf The importance of the ecosystem services of, and the biological values of tropical forests are increasingly recognized amid drastically changing landscapes in the tropics. There is an urgent demand for establishing an appropriate environmental assessment method to keep healthy ecosystem functions and biodiversity along with sustainable forest use based on ecological principles. In this study, we tried to assess logging disturbance using several flying insect groups with their abundance in managed lowland tropical rain forests, Deramakot Forest Reserve (DFR), Sabah, Malaysia, with consideration of seasonal changes. We used a bait trap system to collect flying insects in several strata from the ground to a canopy in four seasons (periods) throughout a year in five forests with different logging histories/intensities. All the studied insects at a lower taxonomic level fluctuated seasonally in their abundance, while the family composition which took into account the relative abundance of families of trapped insects was relatively constant across the plots and the seasons. Although, effects of logging on the abundance of flying insects were distinct at an intensively logged plot, there was no clear difference among undisturbed plot and the moderately disturbed plots harvested by reduced-impact logging (RIL). The abundance of flying insects at higher taxonomic level has a potential of indicating logging disturbance. 2002 eng book VoR https://chikyu.repo.nii.ac.jp/records/2188 http://www.chikyu.ac.jp/ichikawa-pro/top/top.html 持続的森林プロジェクト http://www.chikyu.ac.jp/ 総合地球環境学研究所 The 2nd Workshop on Synergy between Carbon Management and Biodiversity Conservation in Tropical Rain Forests 71 78 https://chikyu.repo.nii.ac.jp/record/2188/files/The_2nd_workshop_Redacted_8.pdf application/pdf 6.2 MB 2018-06-08
