Natural phytoplankton assemblages from Cayuga Lake were maintained under controlled nutrient conditions in large volume continuous flow laboratory cultures. Changes in the C:P ratio, rate of carbon uptake per unit carbon, and species composition were followed in nutrient limited chemostats and nutrient sufficient turbidostats. Rates of change of relative abundance and final values for the C:P ratio and rates of carbon uptake per unit carbon are related to parameters describing the lake populations. These comparisons suggest that Cayuga Lake phytoplankton are limited by phosphorus but are rarely phosphorus deficient. (Author)
