Pathway from Scientific Research

Structural equation modelling (SEM) shows the multivariate effects on CH 4 release and Q 10. Red and blue lines indicate positive and negative relationships, respectively. Grey lines suggest insignificant paths. The width of the solid line is proportional to the correlation strength. Substrate availability includes the ratio of acid to aldehyde forms of vanillyls and syringyls [(Ad/Al)v], soil organic carbon (SOC), and total nitrogen (TN). Microbial communities are represented by total PLFAs, bacterial PLFAs (Bact), fungal PLFAs (Fungi), actinomycetes PLFAs (Act), and the mcrA gene. Sediment properties include sediment water content (SWC) and clay content (Clay). The goodness-of-fit statistics of the model are displayed below the model.
