Abstract

Used data drawn from the literature to test some basic predictions derived from nutrient limitation theory. Contrary to expectation, nitrogen was not better correlated to chlorophyll in N limited lakes (as measured by the TN:TP ratio). The coefficients and precision of the Chla = f(TP) and Chla = f(TN) regression equations vary systematically and concomitantly with TN;TP ratios, and are highest for lakes with TN:TP ratios of 23-28 (by weight). A model is proposed that predicts the coefficients of Chla = f(TP) and Chla = f(TN) equations for lakes with different TN:TP ratios. Results imply an "optimal' TN:TP ratio beyond which the relative rates of increase in chlorophyll with increasing nutrient concentrations are reduced. -from Authors
