Aquatic ecology: Phosphorus, the staff of life
David M. Karl
Abstract
Studies of lakes in North America reveal that concentrations of phosphate, an essential nutrient for aquatic microorganisms, are 100-1,000 times lower than estimated with conventional techniques. Among the implications are the possible need to rethink nutrient dynamics in both freshwater and marine ecosystems..
All organisms require nutrients in trace or comparatively much larger (macro) amounts. Phosphorus is one such macronutrient, accounting for about 2–4% of the dry weight of most cells.
