Proportion of each type of energy flux to total energy fluxes. Food-web nodes include basal resources (leaves, detritus, roots, and algae) and primary decomposers (fungi and bacteria), indicated with icons. Animal consumers are grouped into canopy fauna, surface fauna (from the soil surface and leaf litter), and belowground fauna. Consumer node sizes are proportional to biomasses. The thickness of connecting lines represents the estimated marginal mean of energy fluxes (n= 160; 80 plots 2 sampling seasons). Colors indicate associated trophic functions for soil microorganisms (dashed pattern) and for animals (no pattern). Stacked proportional bar charts summarize the estimated mean of trophic functions for the entire food web (total energy), soil microorganisms (dashed pattern), and animal consumers (no pattern), with the latter further stratified into three compartments (aboveground, soil surface, and belowground). Prey resources for predators in each compartment are displayed in shades of red, with black frames indicating same-stratum interactions. Estimated marginal means of energy fluxes and 95% confidence intervals are shown to the right of the bars. Icons were generated fromBioRender.com. See alsoFigure S1.
