Fig. 3. Biplot of nematode genera and samples based on Principal Component Analysis using log(x+1) transformed abundance of genera. Eigenvalues for ordination axes 1, 2, 3 and 4 were 0.400, 0.175, 0.115 and 0.101, respectively. Cumulative percentage variance of genus data for ordination axes 1, 2, 3 and 4 were 40.0, 57.5, 68.9 and 79.1, respectively.All genera were included in this analysis but only the genera with a dominance ≥ 4.5 % at least on one sampling date at a site are shown in the biplot. Abbreviated names of these genera are in Table 1.
