Fig. 3From: Comparison of microbial taxonomic and functional shift pattern along contamination gradientPartial least squares path modeling (PLSPM) about correlations among sediment properties (C&N and heavy metals), microbial community composition (abundance and diversity) and function (intensity and diversity) (a), as well as between microbial community composition and function of Group H, Group M and Group L respectively (b). Only significant (p < 0.01) correlations are indicated with solid lineBack to article page
