Abstract: The impact of ants, as consumer and decomposer in ecosystems, on soil organic carbon pool is a hotspot in soil fauna research. Recently, effects of ants on soil organic carbon pool dynamics have been mainly documented in terms of soil macro-elements storage, physical and chemical properties, and microbial community. We summarized the effects of ant disturbance on soil organic carbon cycle. Ant nesting alters microhabitat, microclimate, and physicochemical properties of ant nested soils. By re-shaping soil microbial community structure, regulating the succession process and pattern of vegetation, ant nesting directly or indirectly affects the source, allocation, stability, and microcosmic molecular characteristics of soil organic carbon, scaling from micro, local, to landscape scale. In the future, more attentions should be paid on quantifying the contribution of ant disturbance combined with the fluctuations in environmental factors to soil carbon flux dynamics, establishing quantitative model to link and unify ant-induced soil carbon cycle process, and clari-fying mechanisms underlying the impacts of ants on the stability of soil organic carbon pool, and finally revealing the “ecological engineers” role of ants in regulating soil organic carbon cycling.

Key words: ants, soil organic carbon, heterogeneity, mineralization, microorganisms.
