Evaluating acid-aluminum stress in streams of the Northeastern U.S. at watershed, fish community and physiological scales
In spite of overall improvements in air and water quality, biological stress from low pH and high concentrations of inorganic aluminum continue to impact fish and fish habitat in northeastern North America, with independent and interactive effects on individuals, populations and communities. Integra...
