Asymmetrical univariate analyses of variance of the percentage cover of biofilm on panels submerged in different sites in all sampling times.

n = 4. The whole analyses is shown as well as the a priori contrast (i.e. the analyses where the distances to be compared were chosen a priori).ns = not significant;* = p** = p+Because the analysis “effluent vs. controls” was only done for two times of sampling, the degrees of freedom of Time is 1, Di (Ti) and Lo(Di) X Ti are 3 and the residual is 42.
