  abstract = {{C}limate and litter quality are primary drivers of terrestrial decomposition and, based on evidence from multisite experiments at regional and global scales, are universally factored into global decomposition models. {I}n contrast, soil animals are considered key regulators of decomposition at local scales but their role at larger scales is unresolved. {S}oil animals are consequently excluded from global models of organic mineralization processes. {I}ncomplete assessment of the roles of soil animals stems from the difficulties of manipulating invertebrate animals experimentally across large geographic gradients. {T}his is compounded by deficient or inconsistent taxonomy. {W}e report a global decomposition experiment to assess the importance of soil animals in {C} mineralization, in which a common grass litter substrate was exposed to natural decomposition in either control or reduced animal treatments across 30 sites distributed from 43 degrees {S} to 68 degrees {N} on six continents. {A}nimals in the mesofaunal size range were recovered from the litter by {T}ullgren extraction and identified to common specifications, mostly at the ordinal level. {T}he design of the trials enabled faunal contribution to be evaluated against abiotic parameters between sites. {S}oil animals increase decomposition rates in temperate and wet tropical climates, but have neutral effects where temperature or moisture constrain biological activity. {O}ur findings highlight that faunal influences on decomposition are dependent on prevailing climatic conditions. {W}e conclude that (1) inclusion of soil animals will improve the predictive capabilities of region- or biome-scale decomposition models, (2) soil animal influences on decomposition are important at the regional scale when attempting to predict global change scenarios, and (3) the statistical relationship between decomposition rates and climate, at the global scale, is robust against changes in soil faunal abundance and diversity.},
