Short summary
Arctic, Antarctic and alpine biological soil crusts (BSCs) are formed by adhesion of soil particles to cyanobacteria. BSCs influence ecosystems services like soil erodibility and chemical cycles. In cold environments degradation rates are low and BSCs increase soil organic carbon through photosynthesis, whereby these soils are considered as CO2 sinks. This work provides a novel method to visualize BSCs with a focus on cyanobacteria and their contribution to soil organic carbon.
