Table 3 Analysis of variance to examine the effects of blocks, sampling days (1, 3, 7 and 11), emitter types (control, acrylic acid, DMS) nested within blocks, and sampling direction relative to the emitters (upwind, downwind) on Box-Cox transformed (λ = 0.624) DMSP concentrations of U. fenestrata in the field experiments.
