Intraspecific Differences in Nitrate Half‐Saturation Constants for Three Species of Marine Phytoplankton
Abstract
Half—saturation constants (K) for NO_3 uptake were measured on eight clones, belonging to three species, of marine phytoplankton. The clones isolated from oceanic, low—nutrient areas had K values of below 0.75 (mu)M NO_3, while clones of the same species taken from estuarine regions had higher K values (over 1.5 (mu)M NO_3). Other isolated from shelf areas had intermediate (1.2 (mu)M NO_3) or low (0.1 (mu)M NO_3) K values. These data suggest that physiological races of marine phytoplankton are adapted to high or low nutrient levels.

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.
