Fig. 7: Comparative relative abundance of microbial genes involved in biogeochemical cycling before and after the COVID-19lockdown.

C-hydrolysis genes (A), C fixation genes (B), methane metabolism genes (C), N cycling genes (D), P cycling genes (E), and S cycling genes (F). Values formatted as X/Y denote relative abundances in Pre-COVID/Post-COVID samples respectively. Significance levels: *P < 0.05, **P < 0.01, ***P < 0.001.
