Soil fauna diversity increases CO₂ but suppresses N₂ O emissions from soil.

ABSTRACT: Soil faunal activity can be a major control of greenhouse gas (GHG) emissions from soil. Effects of single faunal species, genera or families have been investigated, but it is unknown how soil fauna diversity may influence emissions of both carbon dioxide (CO₂ , end product of decomposition of organic matter) and nitrous oxide (N₂ O, an intermediate product of N transformation processes, in particular denitrification). Here, we studied how CO₂ and N₂ O emissions are affected by species and species mixtures of up to eight species of detritivorous/fungivorous soil fauna from four different taxonomic groups (earthworms, potworms, mites, springtails) using a microcosm set-up. We found that higher species richness and increased functional dissimilarit
