Analysis of variance of number of species, number of species standardized by per algal biomass; and numbers of individuals in experimental patches.

<p>* = <i>P</i> < 0.05</p><p>*** = <i>P</i> < 0.001</p><p>Assemblage is the fixed comparison with three levels: a) monotypic assemblages (E, T, C) or b) (ET, EC and TC). Fragmentation is a fixed comparison with three levels (low, intermediate and high). Pairwise comparisons (SNK tests) for the three assemblage types within each diversity level, means in brackets (<i>n</i> = 4); No. species / biomass and no. individuals were transformed using log(x+1).
