Although soil fauna is not thought to contribute significantly to soil respiration during litter or soil organic matter (SOM) decomposition, the diversity of soil fauna has been found to strongly influence SOM distribution and dynamics. Yet, the functional contribution of soil fauna to many soil processes is not well understood due to methodological limitations and the high complexity of interactions at various spatiotemporal scales. In general, soil fauna has received far less scientific attention than bacteria and fungi (and lately archaea) in soil studies and has been regularly ignored in global biogeochemical models, with maybe exceptions for some earthworms. However, recent studies are raising the awareness of the influence of soil fauna on ecosystems dynamics. For instance, earthworms have been found to be major players in N2O emissions from soils. They exert a strong influence on C stabilization, and they promote the degradation of polycyclic aromatic hydrocarbons (PAHs). Less studied, ants and termites have been found to increase crop productivity in drylands, and different lifeforms of Collembola have been shown to impact microorganisms in various ways over time, thereby potentially affecting C and N cycles within farming systems. The influence of soil fauna indeed manifests over a broad ranges of spatiotemporal scales. For example, some effect such as aggregate formation may cumulate over time and finally contribute to the formation of whole soil profiles, which serve as a framework for other soil processes such as water movement, decomposition, etc. Meanwhile, soil biodiversity is impacted by an increasing human pressure through deforestation, agriculture intensification, habitat fragmentation or climate change (increasing temperatures, extreme weather events), which leads to soil biodiversity loss, in particular of soil fauna, with associated consequences on soil functioning and resilience. 606 $aEnvironmental science, engineering and technology$2bicssc 606 $aScience: general issues$2bicssc 610 $abiogeochemical cycles 610 $aC sequestration 610 $aearthworms 610 $agreenhouse gas 610 $amacroarthropods 610 $amicroarthropods 610 $anematodes 610 $aprotists 610 $aresilience 610 $asoil alterations 610 $asoil functions 610 $asoil stability 610 $asoil structure 615 7$aEnvironmental science, engineering and technology 615 7$aScience: general issues 700 $aLuz Cayuela$b Maria$4edt$01295610 702 $aClause$b Julia$4edt 702 $aFrouz$b Jan$4edt 702 $aBaveye$b Philippe C$4edt 702 $aLuz Cayuela$b Maria$4oth 702 $aClause$b Julia$4oth 702 $aFrouz$b Jan$4oth 702 $aBaveye$b Philippe C$4oth 906 $aBOOK 912 $a9910557395903321 996 $aInteractive Feedbacks between Soil Fauna and Soil Processes$93023672 997 $aUNINA
