Carbon partitioning in a wet and a semiwet subarctic mire ecosystem based on in situ 14C pulse-labelling

► The recovery of 14C below-ground was higher in September compared to July. ► The recovery of 14C in DOC was higher in the semiwet ecosystem compared to the wet ecosystem. ► The relative amount of 14C partitioned to “slow” versus “fast” C-pools differed between vegetation types.
