Rapid physiological assays for nutrient demand by the plankton. II. Phosphorus

Warwick F. Vincent

Freshwater Section, Ecology Division DSIR, Box 415, Taupo, New Zealand

Received on October 1, 1980; accepted on May 1, 1981 Four bioassays for phosphorus demand were compared. 32P-turnover rates provided an integrated measure of transport capacity of the assemblage and ambient orthophosphate levels, but rates were often not simply exponential and could not be accurately quantified by a single rate constant. ATP responses to phosphorus enrichment were transient and they poorly separated natural plankton populations with very different degrees of P-deficiency. Alkaline phosphatase activity corresponded well with other measures of phosphorus demand although low activities did not necessarily imply non-limiting phosphorus conditions. Selective luxury accumulation of N and P by the seston from an N + P enrichment provided the most informative guide to the relative demand for the two elements. No single approach could be considered conclusive on its own, but in combination the assays provided a reliable measure of phosphorus demand and deficiency within natural assemblages of plankton.
