Effect of a pollutant on the normalized Pn under 1000 μmolphotonm^-2 s^-1 PAR.

Abstract

<p>a, the normalized Pn of all five species regressed with respect to <i>I</i> using linear, power, exponential, and hyperbolic functions. b, the normalized Pn of each species regressed with respect to <i>I</i> using the hyperbolic function. AIC is Akaike's information criterion. ** means significant at <i>P</i> ≤ 0.01.</p
