Fig. 4

Sample points are distinguished by site and core depth by shape and color, respectively. dbRDA1 (variation 47%) and dbRDA2 (variation 22%) axes are displayed, which constrain the Bray-Curtis distance matrix with geochemical parameters Fe2+, PO43−, NH4+, SiO2, and H2S. The total model (F = 4.99, p < 0.01, Df: 5, 34) and each individual parameter (p < 0.05) was significant.
