Dissertation Research: Use of Food Web Analyses to Examine Ecosystem Response to a Detrital Resoruce Manipulation

小行星931566 本计画结合稳定同位素添加与肠道分析来探讨溪流食物网的结构。 特别重要的是微生物生产的估计和评估其在流食物网的重要性。 这种方法将被用来了解资源改变对食物网属性的影响：大量减少凋落物投入的影响。 本研究将确定食物网分析在检测环境变化的生态影响，抑制生态系统资源的效用。 研究结果将在森林和河流管理、渔业和保护生物学方面具有价值。 ***

931566 Meyer This project examines the structure of stream food webs using a combination of stable isotope addition and gut analysis. Of particular importance is the estimation of microbial production and assessment of its importance in stream food webs. This approach will be used to understand the effects of a resource alteration on food web properties: the effects of a large reduction in litter inputs. %%% This study will determine the utility of food web analysis in detecting the ecological effects of environmental alterations that depress ecosystem resources. The results will be of value in forest and stream management, fisheries, and conservation biology. ***
