Short summary

We found that the dominant abiotic and biotic correlates of CO2 and CH4 fluxes change in strength and interactions as permafrost thaw progresses in a sub-arctic peatland. Our results emphasize the importance of incorporating transitional stages of thaw in landscape-level C budgets and highlight that end-member thaw stages do not adequately describe the variability in structure-function relationships present along a thaw gradient.
