Abstract
Rates of nutrient regeneration by zooplankton (micromolecule/mg dry wt/hr) in southern Lake Huron from April to August 1975 ranged from undetectable to 2.6 for total phosphorus (TP), undetected to 0.8 for total soluble phosphorus (TSP), undetectable to 0.12 for soluble reactive phosphorus (SRP), undetectable to 0.97 for ammonia (NH3), undetectable to 3.8 for nitrate plus nitrite (NO3 + NO2), and undetectable to 2.9 for silica (SiO2). Two diel experiments were conducted. Times of highest rates of regeneration varied for the different nutrients on these dates. (Copyright (c) Internat. Assoc. Great Lakes Res. 1983.)
