PERMANOVA examining Bray-Curtis distances between and within samples of assemblages in entire landscapes (a), sparse turfs (b) or dense turfs (c) in experimental landscapes and corresponding pair-wise comparisons of levels of factor Composition.

*<p> indicates <i>P</i><0.05 and ** indicates <i>P</i><0.005</p><p>Site is random with two levels; Composition is a fixed factor four levels in a); three levels in b) and c); <i>n</i> = 3. Entries are the mean distances between each pair in each test of Composition, with bold entries with asterisks being significant at <i>P</i> = 0.05. Multivariate patterns for entire habitats are shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0061349#pone-0061349-g004" target="_blank">Fig. 4</a>.
