Influence of light intensity, light quality, temperature, and daylength on uptake and assimilation of carbon dioxide and sulfate by lake plankton [electronic resource] / by Russell L.

"The biochemical composition (protein, carbohydrate and lipid) of newly-produced phytoplankton biomass in Lake Ontario was determined under environmentally controlled conditions to determine the variables which control production. The quantity was related to incident light intensity and water temperature but was insensitive to light quality and nutrient additions. The allocation of carbon to carbohydrate polymer storage for nightgrowth was strictly proportional to night length. The proportion of carbon contained in protein was strongly correlated with insitu water temperature. Lack of cross-correlation suggests that temperature and daylength exert independent constraints on the biochemical composition of lake microplankton"--Management perspective.
