Figure 4

Beta (a) and Alpha (a) diversity by storage media, duration and extraction method. (a) PC2 values displayed in Fig. 3 plotted by storage time. (b) Alpha diversity metric, the Shannon Index were calculated in Phyloseq (version 1.20.0) and plotted by storage time displayed. For both (a,b) the samples are coloured by extraction kit (blue = QIAamp, red = PowerSoil), with shape denoting storage media (circle = ethanol, triangle = Bead solution) and extraction method). Abbreviations: PowerSoil/Bead solution (PB), PowerSoil/75% ethanol (PE), QIAamp/Bead solution (QB) and QIAamp/75% ethanol (QE).
