Table 6.

This table shows the results from an analysis of variance coming from the experiment on mutual effects of Paramecium caudatum and Rotatoria sp. on each other. The ANOVA table displays the sum of squares (SS), degrees of freedom (df), the F-ratio, and the probability of error (prob > F) based on final population size. Effects came from repeating the experiment (exp), the inducer species (ind), and interactions between repeating the experiment and inducer species (exp × ind).
