Steady-state biovolumes in single- and two-species cultures for Paramecium and Colpidium.

These values are used to estimate competition coefficients, and the standard errors of each are used to estimate 95% confidence intervals for each coefficient. K is carrying capacity and the α's are the Lotka-Volterra competition coefficients, subscripted c and p for Colpidium and Paramecium, respectively. Steady-state densities in two-species cultures are (Colpidium) and (Paramecium).
