Literature-based synthesis of nutrient stressor-response relationships to inform assessment, monitoring, and criteria development in rivers and streams
Eutrophication from nutrient pollution is a major stressor of freshwater ecosystems globally. Despite recognition of this problem by scientists and stakeholders, synthesis of scientific evidence is still needed to inform nutrient-related management decisions and policies, especially for streams and rivers. Nutrient-stressor response relationships are complicated by many interacting stressors, complex causal pathways involving multiple biotic assemblages, and the spatiotemporal variability of lotic ecosystems. A rigorous assessment of nutrient-stressor response relationships and modifying factors is a critical first step for identifying, managing, and restoring aquatic resources impaired by eutrophication. We describe three ongoing systematic reviews that compile and synthesize literature on the chlorophyll-a, diatom, and macroinvertebrate responses to nutrients in streams. These reviews will provide a state-of-the-science body of evidence for assessing nutrient impacts to the most widely-used indicators of biological responses to nutrients. These reviews answer questions regarding evidence demonstrating relationships between total nitrogen or total phosphorus concentrations and selected biotic endpoints in rivers and streams and examine how other factors affect these relationships.
