| Abstract |
The report describes the quantitative effects of experimentally increasing the acidity of a mountain stream ecosystem to pH levels frequently found in incident precipitation in the northeastern United States. The field experiment was designed to test the hypothesis that such acidity of the streamwater would alter the biogeochemistry and the behavior and metabolism of microorganisms, periphyton, macroinvertebrates and fish. |
