The effect of environmental factors on phytoplankton growth: Light and the interactions of light with nitrate limitation1
Open accessAbstract
The effects of simultaneous limitations of light and nutrient on growth were investigated with turbidostat and chemostat cultures of Scenedesmus sp. and Fragilaria crotonensis. The combined effects were greater than the sum of individual effects and were not multiplicative. Under nitrate‐limited conditions the cell quota of the limiting nutrient for a constant growth rate and the subsistance quota (qo) increased as irradiance decreased. Within a certain limit of growth rates, light and qN can compensate for each other in maintaining growth rate. Under nutrient‐sufficient conditions, cell quotas of C, N, and P, and cellular chlorophyll a concentration increased as light decreased below saturation. The cell quotas are the maximum level (qm) that can be achieved at a given irradiance. Cell quotas of nonlimiting nutrients in nutrient‐limited cultures are the same as these qm values. The increasing levels of qm and qo with decreasing irradiance indicate that nutrient requirements increase as irradiance decreases.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
