Fig. 5.

Analysis of species β-diversity using ordination by non-metric multidimensional scaling (NMDS). A dissimilarity matrix was calculated using the Bray-Curtis dissimilarity method. The NMDS ordination plot shows no obvious pattern for any of the treatments. Samples are labelled indicating the farm (SF1, SF2, SF3, etc) and the drug used for treatment (F, fenbendazole (green); I, ivermectin (blue); M, moxidectin (red)). Pre-treatment samples are shown in black. (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)
