a decreasing trendP < .0001
Moreover, the mean taxa determinism of bacterial communities exhibited a decreasing trend from S03 to S07 (mean determinism: S03, 39; S05, 22; S07, 19; P < .0001 by the Kruskal–Wallis test), with significant differences observed among the three stations by the Dunn Kruskal–Wallis test (S03 vs S05, adjusted P = .04; S03 vs S07, adjusted P < .0001; S05 vs S07, adjusted P < .0001).
