Statistics of the soil faunal biomass distribution: linear regression slope, intercept, significance, food-web nodes and links with averages±standard deviation.

Although forests belong to the only agroecosystem with a rather small width of the body-size range, the mean coefficient and significance of their biomass–size linear regressions are by far the highest. Not one of the log-log-scaled regression lines of biomass on binned body-mass was weak. Besides for forests, biodiversity at genus level was statistically undistinguishable between open-canopy ecosystems.
