世界各地的热带森林景观正在被广泛砍伐并转为农业，对生物多样性和潜在的生态系统功能造成严重后果。在这里，我们调查栖息地的干扰和蚂蚁和白蚁的功能多样性之间的关联-两个数量上占主导地位，功能上重要的类群在热带雨林中的捕食，分解，养分循环和种子传播的关键作用。我们比较了蚂蚁和白蚁的发生和组成内的标准化体积的土壤和枯木的老增长的森林，采伐森林和油棕种植园在沙巴，马来西亚婆罗洲。白蚁发生的频率大大低于转换的栖息地比在老的增长森林，而蚂蚁的发生率最高的记录森林和最低的老的增长森林。所有白蚁喂养组发生率低，在干扰的栖息地，土壤饲养者发生频率甚至低于木材饲养者。蚂蚁功能组表现出更多的变量协会，一些机会主义和行为优势群体更丰富的退化栖息地。蚂蚁和白蚁在热带生态系统中的重要性和这种不同的组合变化模式表明，生态系统功能可能会显着改变转换的栖息地。
Forested tropical landscapes around the world are being extensively logged and converted to agriculture, with serious consequences for biodiversity and potentially ecosystem functioning. Here we investigate associations between habitat disturbance and functional diversity of ants and termites-two numerically dominant and functionally important taxa in tropical rain forests that perform key roles in predation, decomposition, nutrient cycling and seed dispersal. We compared ant and termite occurrence and composition within standardised volumes of soil and dead wood in old growth forest, logged forest and oil palm plantation in Sabah, Malaysian Borneo. Termites occurred substantially less frequently in converted habitats than in old growth forest, whereas ant occurrences were highest in logged forest and lowest in old growth forest. All termite feeding groups had low occurrence in disturbed habitats, with soil feeders occurring even less frequently than wood feeders. Ant functional groups showed more variable associations, with some opportunist and behaviourally dominant groups being more abundant in degraded habitats. The importance of ants and termites in tropical ecosystems and such differing patterns of assemblage variation suggest that ecosystem functioning may be significantly altered in converted habitats.
