9726986 Kaplan Over the past 30 years, the Stroud Water Research Center has developed and used long-term ecological data for White Clay Creek watershed in three interrelated areas of inquiry: biogeochemistry, microbial ecology, and macro-invertebrate ecology. These studies represent a unique documentation of the temporal variability in a protected Piedmont stream ecosystem. The depth and detail in these data provide the baseline for a wide variety of research projects concerning the dynamics of stream ecosystems, and are essential in the evaluation of long-term patterns of environmental change. This current project will (1) maintain existing watershed installations needed to continue acquisition of long-term data on White Clay Creek, (2) address the data management needs of the long-term research project, including making the data available to the research community, and (3) test hypotheses concerning stream ecosystem structure and function under stable and/or recovering conditions that can only be examined with long-term data. This study is valuable in that it provides a long-term perspective on how land use history and atmospheric deposition affect stream water quality, organisms in stream communities, and ecosystem structure and function.

在过去的30年里，斯特劳德水研究中心已经开发和使用长期的生态数据白色粘土溪流域在三个相互关联的调查领域：土壤地球化学，微生物生态学和大型无脊椎动物生态学。这些研究代表了一个受保护的皮埃蒙特河流生态系统的时间变化的独特文件。这些数据的深度和详细程度为关于河流生态系统动态的各种研究项目提供了基线，并且对于评价环境变化的长期模式至关重要。当前项目将（1）维护继续获取白色粘土溪长期数据所需的现有流域设施，（2）满足长期研究项目的数据管理需求，包括向研究界提供数据，以及（3）在稳定和/或恢复条件下，检验关于河流生态系统结构和功能的假设，这些假设只能用长期-术语数据。这项研究是有价值的，因为它提供了一个长期的角度来看，土地利用的历史和大气沉积如何影响溪流水质，生物在溪流群落，生态系统的结构和功能。
