Redundant analysis predictingmetal distribution using landscape variables
produced a triplot similar to that of the RDA of metal distribution
based on sediment physicochemical variables (p = 0.009). RDA axis 1
and axis 2 both support a significant effect on the variability of sediment
metal (Fig. 2B) and accounted 72.52% of variance in landscape variables.
