LTREB: Stream Ecosystem Structure and Function within a Maturing Deciduous Forest

9726986卡普兰在过去的30年里，干流水研究中心在生物地球化学、微生物生态学和大型无脊椎动物生态学三个相互关联的研究领域开发和使用了白泥溪流域的长期生态数据。这些研究代表了受保护的山前溪流生态系统中时间变异性的独特文献。这些数据的深度和细节为各种有关河流生态系统动态的研究项目提供了基线，对评估环境变化的长期模式至关重要。目前的项目将(1)维护现有的流域设施，以继续获取白泥溪的长期数据；(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/或恢复的条件下检验有关河流生态系统结构和功能的假设，这些假设只能用长期数据进行检验。这项研究的价值在于，它为土地利用历史和大气沉积如何影响溪流水质、溪流群落中的生物以及生态系统结构和功能提供了一个长期的视角。

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.
