A physical-biogeochemical mechanism for negative feedback between marsh crabs and carbon storage
2019
Environmental Research Letters
34 Tidal marshes are valuable global carbon sinks, yet large uncertainties in coastal marsh 35 carbon budgets and mediating mechanisms limit our ability to estimate fluxes and predict 36 feedbacks with global change. To improve mechanistic understanding, we assess how net carbon 37 storage is influenced by interactions between crab activity, water movement, and 38 biogeochemistry. We show that crab burrows enhance carbon loss from tidal marsh sediments by 39 physical and chemical feedback
