Post-logging silvicultural effects on dung beetles in Malaysian Borneo

Species level dung beetle data collected in unlogged forest, logged forest left naturally regenerating and logged forest subsequently treated with vine-cutting and enrichment planting in Malaysian Borneo. The data comprises information collected across 4 different years, with baited traps set as transects within the three forest types. We explored the hypothesis that post-logging silviculture, through removal of important microhabitats, has deleterious consequences on dung beetle effective diversity, functional diversity and species composition. Contrary to this hypothesis, we found that dung beetle communities in intensively treated forest maintain similar effective and functional diversity to unlogged and naturally regenerating logged forest, with species composition in treated forest also similar to that in the naturally regenerating forest.本数据集采集自马来西亚婆罗洲地区的三类森林类型：未采伐森林、天然更新的采伐后森林，以及后续实施藤蔓修剪与人工补植的采伐后森林，采集的样本为蜣螂（dung beetle）的物种水平数据。数据集涵盖4个不同年份的采集信息，三类森林中均以样带形式布设了带饵诱捕器。我们曾提出研究假说：采伐后营林措施通过破坏关键微生境，会对蜣螂的有效多样性、功能多样性及物种组成产生有害影响。而本研究结果与该假说相悖：经高强度营林处理的森林中，蜣螂群落的有效多样性与功能多样性与未采伐森林及天然更新的采伐后森林并无显著差异，且处理后森林的蜣螂物种组成也与天然更新的采伐后森林相近。
