ALKALINE PHOSPHATASES AND PHOSPHORUS AVAILABILITY IN LAKE KINNERET1,2
Abstract
Alkaline phosphatase activities were determined in water samples taken from three depths at a central point in Lake Kinneret (Lake Tiberias). Seasonal fluctuations were shown, and also indications of induction‐repression or activation and inhibition mechanisms, or both, with respect to total phosphorus, and, during stratification, the existence of a metalimnetic layer of intense activity. Phosphatase activities with “natural” substrates and estimates of phosphorus availabilities were derived by measuring release of soluble inorganic orthophosphate from samples saturated with chloroform. Phosphorus, which appeared to be adequate during the main bloom season, may have become limiting from the end of summer until overturn. In epilimnetic waters 30–66% of total phosphorus was hydrolyzed with a turnover time of 3–6 days.

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.
