Protecting our freshwater resources requires us to identify critical elements essential for the long term health and sustainability of aquatic ecosystems. These include not only identifying which specific organisms in a community are important, but also understanding how all organisms within a community interactively contribute to the functioning of ecosystems. Additionally, it is also important to understand the mechanisms of energy and material flow between organisms and their surroundings to appreciate the underlying processes that are responsible for maintaining healthy ecosystems. Here we are proposing an integrative approach that combines physiology, ecology, and toxicology disciplines to address how stress related to various aspects of land-use (nutrient loading and metal contamination) influence the integrity and ecological services provided by freshwater mussel beds. Mussels are useful biological indicators of ecosystem health because they integrate metals and other contaminants from the water column into their shell and tissue. Our study will be focused in

保护我们的淡水资源要求我们确定对水生生态系统的长期健康和可持续性至关重要的关键要素。这不仅包括确定群落中哪些特定生物是重要的，还包括了解群落中的所有生物如何相互作用地促进生态系统的功能。此外，了解生物体及其周围环境之间的能量和物质流动机制也很重要，以了解负责维持健康生态系统的基本过程。在这里，我们提出了一个综合的方法，结合生理学，生态学和毒理学学科，以解决如何应力有关的各个方面的土地利用（营养负荷和金属污染）的影响的完整性和生态服务提供的淡水贻贝床。贻贝是生态系统健康的有用生物指标，因为它们将水体中的金属和其他污染物整合到它们的外壳和组织中。我们的研究将集中在
