N2 - Carbon cycling models consider soil carbon sequestrationa key process forclimate change mitigation. However, these models mostly focus on abiotic soil processes and, despite its recognizedcritical mechanistic role,do not explicitly include interacting soil organisms. Here, we use a literature study to show that even a relatively simple soil community (heathland soils) containslarge uncertainties in temporal and spatialfood web structure. Next, we used a Lotka-Volterra-based food web model to demonstratethat, due tothese uncertainties, climate change can eitherincrease ordecrease soil carbon sequestration to varying extents. Both the strength and direction of changes strongly depend on: (1) the main consumer’s (enchytraeid worms) feeding preferences; and (2) whether decomposers (fungi) or enchytraeid worms are more sensitive to stress. Hence, even for asoil community with a few dominant functional groups and a simulation model with a few parameters ,filling theseknowledge gaps isacritical first steptowardsthe explicit integration of soil food web dynamicsinto carboncycling models in order tobetter assess48the role soils play in climate change mitigation.
