Table 2. Results of the canonical analysis of principal coordinates.
Results of the Canonical Analysis of Principal coordinates (CAP) testing the contribution of sediment (TOM%, sand content), water salinity and concentrations of trace metals in sediments (As, Fe, Pb) to the multivariate distribution of meiofaunal (eDNA) assemblages in the samples from Rio Doce estuary. Spearman correlation values for each sediment variable are described for in CAP axis one and two. proportion of variability explained by CAP axes are highlighted, F for statistic, significant results (p < 0.05) are in bold.
