Importance of hydrogen ions and aluminium in regulating the structure and function of stream ecosystems: an experimental test

Technical Report ·
OSTI ID:7000488
Experiments simulating spring acidic snowmelt episodes were conducted to determine the effects of short-term inputs of H/sup +/ and Al on the chemistry and biology of a poorly buffered mountain stream. HCl and AlCl/sub 3/ were added in separate experiments to first- to third-order reaches of a New Hampshire stream. Some aspects of the study addressed cation exchange, foam production at the water surface, total phosphorus measurements, drift of mayfly nymphs, blackfly and chironomid larvae and stream pH.
