Feeding preferences of the amphipod Ampithoe ramondi (top) and the majid crab Acanthonyx lunulatus (bottom) on three Gracilaria species offered simultaneously. Bars represent means +1 SE. Analyses and significant groupings are from non-parametric Friedman’s tests followed by the appropriate pair-wise comparisons. Negative numbers indicate net growth in the presence of consumers.
