9408029 Bach This project will investigate the effects of insect herbivory and abiotic disturbance on rates and patterns of primary succession on sand dunes, with emphasis on the colonizing plant Salix cordata and the specialist folivorous beetle Altica subplicata. This project will examine the effect of sand burial and flooding (two natural disturbances) on Salix performance and plant succession, and the interaction between herbivory and disturbance in influencing sand-dune succession. There has been only limited study of the interactive effects of disturbance and herbivory on succession, yet such interactions may have major influences on the course of community change. All biological communities are in a state of successional change. Understanding the mechanisms that drive this change will improve our ability to manage altered ecosystems and biological preserves, promote ecosystem recovery, and mitigate the loss of biological diversity.

小行星9408029 本项目将调查昆虫植食性和非生物干扰对沙丘初级演替速率和模式的影响，重点是定殖植物Salix cordata和专门的食叶甲虫Altica subplicata。 本项目将研究沙埋和洪水（两种自然干扰）对沙柳性能和植物演替的影响，以及草食动物和干扰之间的相互作用对沙丘演替的影响。 干扰和植食性对演替的交互作用研究有限，但这种交互作用可能对群落变化过程产生重大影响。 所有的生物群落都处于演替变化的状态。 了解驱动这种变化的机制将提高我们管理改变的生态系统和生物保护区的能力，促进生态系统恢复，并减轻生物多样性的损失。
