Two series of experiments were carried out to determine the relation of the rate of phosphorus and nitrogen excretion by the planktonic rotifers to ambient temperature and individual body weights of these animals. The following formulas describing this relation were obtained:
$${E_P} = 0.0154\,{W^{ - 1.27\,{}_e0.096\,T}}\,{E_N} = 0.0879\,{W^{ - 1.01\,{}_e0.88\,T}}\,,$$
, where EPand EN denote the rate of P and N excretion, respectively, in µg·mg dry wt−1·h−1, W is body weight in µg dry weight, and T is temperature in °C.
