Genes displaying significant enrichment in either retreats or nets versus rock biofilms (p < 0.05; ANOVA with Tukey’s HSD post-hoc testing) are indicated with asterisks (*). Panels (A–E) show genes encoding enzymes of the denitrification pathway: nitrate reductase (narG) (A), cytochrome cd-1 nitrite reductase (nirS) (B), copper containing nitrite reductase (nirK) (C), nitric oxide reductase (norB) (D), nitrous oxide reductase (nosZ) (E). Y-axes are identical in scale in (A–E). Panels (F–J) show genes encoding high affinity cytochrome-c oxidase (cbb3) (F), nickel-iron hydrogenase (NiFe-hyd) (G), iron-iron hydrogenase (FeFe-hyd) (H), nitrogenase (nifH) (I), and reductive (white) and oxidative [43] dissimilatory sulfite reductases (dsr) (J). For panels (F–J), the vertical axes have the same units but different ranges. In (A–J), the bold line is the sample mean; the boxed region is the interquartile range (IQR); top and bottom whiskers indicate [Q3 + 1.5*IQR] and [Q1–1.5*IQR] respectively; and outliers are marked by open circles.
