Abstract99-15133LowmanCanopy Herbivory and Soil Processes in a Temperate and Tropical ForestInsects that feed on the foliage of trees can influence the quality of forest soils by dropping feces and fragments of leaves onto the forest floor. They can also modify the chemistry of rainwater that passes through the canopy. The effects of herbivore activity on the properties of forest soils are poorly understood. Potentially, insects may change soil fertility and the rates of decomposition of leaves that have fallen to the forest floor. In this project, the investigators will study the effects of insect herbivores on forest soils in a temperate and tropical forest. Sampling and experimental approaches will be used to assess the effects of canopy herbivores on soil nutrients and decomposition. The results of this study will improve understanding of how natural and managed forests maintain their fertility, and the role that insects play in forest and soil health.

摘要99-15133Lowman温带和热带森林中的冠层食草和土壤过程以树叶为食的昆虫可以通过将粪便和树叶碎片掉落到森林地面上来影响森林土壤的质量。它们还可以改变穿过树冠的雨水的化学成分。人们对食草动物活动对森林土壤特性的影响知之甚少。昆虫可能会改变土壤肥力和掉落到森林地面的树叶的分解速度。在这个项目中，研究人员将研究食草昆虫对温带和热带森林土壤的影响。将采用采样和实验方法来评估冠层食草动物对土壤养分和分解的影响。这项研究的结果将提高人们对天然林和管理森林如何保持肥力以及昆虫在森林和土壤健康中所发挥的作用的了解。
