The global reported ranges of numbers of individuals m−2 and biomass m−2 for ecosystem engineers and macroinvertebrates.

*Majority exotic species.**Percent of maximum biomass (all macroinvertebrates) reported.***Conversion of fresh weights to dry weights (g) are estimates and followed that of [15]: termite fresh weight×0.27 = dry mass, earthworm fresh mass×0.15, ant fresh mass×0.23, and other macroinvertebrates fresh mass×0.30. These conversions do not apply to the invertebrates sampled in this study as those were dried and weighed.
