翻译后摘要：在东南亚的森林砍伐率是最高的任何热带地区，与扩张的油棕是一个重要因素。尽管如此，很少有研究调查油棕扩张对节肢动物区系的影响。我们在这里报告的第一项研究的影响，森林转化为油棕榈对整体节肢动物丰度，生物量和组成。我们比较了节肢动物的丰度和生物量，收集附生鸟巢蕨类植物，树冠，落叶层之间的原始森林，采伐森林和油棕种植园。与原始林相比，油棕林的节肢动物丰度、生物量和凋落物量均较原始林低（分别为67.2%、2.3%和77.1%），生物量分别为87.5%、37.9%和72.4%。然而，并不是所有的节肢动物的订单显示相同的下降水平，与一些群体具有较高的丰度和生物量在油棕，导致在改变的群落组成的附生植物和树冠在油棕与森林相比。我们的研究结果表明，森林转化为油棕对森林生态系统所有分区中的无脊椎动物都产生了不利影响。
Abstract: Deforestation rates in South-East Asia are among the highest of any tropical region, with expansion of oil palm being one important factor. Despite this, few studies have investigated the impact of oil palm expansion on the arthropod fauna. We report here the first study on the impact of forest conversion to oil palm on overall arthropod abundance, biomass and composition. We compared arthropod abundance and biomass, collected from epiphytic bird's nest ferns, the canopy, and leaf litter between primary forest, logged forest and oil palm plantation. Epiphytes, canopy and litter all contained a lower abundance (epiphytes: 67.2%, canopy: 2.3% and litter: 77.1% reduction) and biomass (epiphytes: 87.5%, canopy: 37.9% and litter: 72.4% reduction) of arthropods in oil palm compared with primary forest. However, not all orders of arthropods showed the same level of decline, with some groups having higher abundance and biomass in oil palm, resulting in an altered community composition in the epiphytes and canopy in oil palm compared with forest. Our results show that forest conversion to oil palm impacts detrimentally on invertebrates in all compartments of the forest ecosystem.
