A Non-metric multidimensional scaling (NMDS) representation of Bray-Curtis community similarity. B Similarity between communities at start and in undiluted (i.e. high predation pressure) samples from the same experiment was significantly higher (p < 0.001) than the similarity between communities at start and in diluted (i.e. reduced grazing) samples. C Community similarity within treatments was significantly higher for the reduced predation treatment (p < 0.001), indicating reduced beta diversity and community homogenisation. Grey points in B and C represent pairwise community comparisons, black points represent means of community comparisons and the black horizontal lines are ±1 standard deviation.
