Figure 3. Clustering of samples due to storage conditions by PCoA, based on Bray-Curtis similarity distance.
The first two principal coordinates are plotted on the x- and y-axes, respectively (representing 57.3% of the total variation). Faecal collections sampled at three different time points are represented by circle (●) for collection 1, triangle (▲) for collection 2, and square (■) for collection 3. Storage conditions are indicated by colour.
