Figure 2.

Non‐metric multidimensional scaling (nMDS) ordination (Bray–Curtis distance) of ARISA‐derived bacterial community profiles at months 1, 2 and 3, with six replicates per substrate per time‐point. Groupings are specified according to substrate. Data from an initial analysis (T0) of the bacterial community in the water column (n = 2) are plotted alongside the monthly water data. The water groupings are of cumulative data at each time‐point, inclusive of T0, for reference. Points plotting close to each other show a more similar community than distant ones
