Forest management and the colonization of artificial tree holes by aquatic insect larvae

Human activities in forests lead to alteration or even destruction of habitats for numerous organisms, often resulting in a decline of biodiversity. Insects inhabiting water-filled tree holes may be especially sensitive to human impact as they require these microhabitats for at least part of their life cycle, with larvae mainly feeding on plant and animal debris accumulating in the water, until they actively disperse in their adult stage. The processes leading to successful colonization of these microhabitats are not well understood, and it is unclear how forest management could influence them. We used sequential collection and recording of larval communities in artificial tree-hole analogues to study the process of colonization by aquatic tree-hole insects. We focused on the effects of parameters related to forest management as well as microhabitat properties on abundance, species richness and community composition during colonization of artificial tree holes by aquatic tree-hole insec..., , # Forest management and the colonization of artificial tree holes by aquatic insect larvae

森林中的人类活动会改变甚至破坏众多生物的栖息地，往往导致生物多样性下降。栖息于积水树洞的昆虫对人类活动影响可能尤为敏感，因为它们在生命周期的至少一个阶段依赖这类微生境：幼虫主要以水中积聚的动植物碎屑为食，直至成虫阶段主动扩散。目前学界对这类微生境的成功定殖过程仍知之甚少，尚不明确森林管理如何对其产生影响。本研究通过对人工树洞模拟物中的幼虫群落进行连续采样与记录，探究水生树洞昆虫的定殖过程。我们重点关注了与森林管理相关的参数以及微生境属性对水生树洞昆虫定殖人工树洞过程中的种群丰度、物种丰富度及群落组成的影响。... , # 森林管理与水生昆虫幼虫对人工树洞的定殖
