Combinations of phosphorus, nitrogen, and carbon were added to several small lakes in northwestern Ontario, Canada, at rates similar to those in many culturally eutrophied lakes. Phosphate and nitrate caused rapid eutrophication. A similar result was obtained with phosphate, ammonia, and sucrose, but recovery was almost immediate when phosphate additions only were discontinued. When two basins of one lake were fertilized with equal amounts of nitrate and sucrose, and phosphorus was also added… Expand
Eutrophication of lakes cannot be controlled by reducing nitrogen input: Results of a 37-year whole-ecosystem experiment
Reducing nitrogen inputs increasingly favored nitrogen-fixing cyanobacteria as a response by the phytoplankton community to extreme seasonal nitrogen limitation, and the lake remained highly eutrophic, despite showing indications of extreme nitrogen limitation seasonally. Expand
Phytoplankton Community Responses to Nutrient Addition in Lake 226, Experimental Lakes Area, Northwestern Ontario
Inclusion of phosphorus in fertilizer added to one of two basins of a small lake, between which water exchange was greatly reduced by a vinyl sea-curtain, significantly increased epilimneticExpand
Eutrophication of Lakes and Reservoirs
Eutrophication is caused by enrichment of waters with excess plant nutrients, which leads to enhanced vegetation growth. Abundant plant growth produces an undesirable disturbance to the balance ofExpand
Nutrient dynamics and fertilization effects in two oligotrophic coastal mountain B.C. lakes
Selected nutrient dynamics and the effects of nitrogen and phosphorus fertilization on Twin Lakes, British Columbia, were examined for this research. Twin East Lake and Twin West Lake are smallExpand
Nitrogen, phosphorus, and eutrophication in streams
Abstract Flowing waters receive substantial nutrient inputs, including both nitrogen (N) and phosphorus (P), in many parts of the world. Eutrophication science for rivers and streams hasExpand
The importance of nitrogen in Pyramid Lake (Nevada, USA), a saline, desert lake
The increase in human development in the downstream portion of the Pyramid Lake drainage basin has resulted in increased nutrient loading to the lake. Since this is a deep, terminal lake, concernExpand
Nitrate suppresses internal phosphorus loading in an eutrophic lake.
The results suggest that knowledge of a lake's nitrogen budget may be a useful tool in the design of lake remediation efforts, even though phosphorus is typically the limiting nutrient. Expand
Phosphorus budget and productivity of an experimental lake during the initial three years of cage aquaculture
An experiment was conducted at the Experimental Lakes Area (ELA; Ontario, Canada) to investigate the effect of rainbow trout (Oncorhynchus mykiss) cage aquaculture on the phosphorus budget andExpand

It is concluded that long-term, whole-ecosystem experiments and case histories of lake recovery provide the only reliable evidence for policies to reduce eutrophication and the case for phosphorus control has been strengthened. Expand
Nutrient limitation of phytoplankton in a central Arizona reservoir
The influence of added nutrients nitrogen, phosphorus and carbon on the phytoplankton of a small recreational reservoir in central Arizona was investigated during the summer, 1974. Polyethylene bagsExpand


Phosphorus, Nitrogen, and Algae in Lake Washington after Diversion of Sewage
After diversion of sewage effluent from Lake Washington, winter concentrations of phosphate and nitrate decreased at different rates, but nitrate remained at more than 80 percent of the 1963 value and free carbon dioxide and alkalinity remained relatively high. Expand
Atmospheric Carbon Dioxide: Its Role in Maintaining Phytoplankton Standing Crops
The results demonstrate that invasion of atmospheric carbon dioxide may be sufficient to permit eutrophication of any body of water receiving an adequate supply of phosphorus and nitrogen. Expand
