Short summary
Short summary
This study analysed changes of above- and belowground production and litter mass loss of vascular plants due to rewetting of drained temperate fens across Europe by comparing rewetted, drained and undrained fens. Belowground production and decomposition did not differ between hydrological statuses, and were more impacted by soil depth and nutrient availability than water level regime. The results were obtained during an extremely dry, warm growing season with an unknown impact.

Short summary
Plants from Polish wetlands and dry grasslands exhibit habitat-specific, century-scale shifts in carbon and nitrogen isotope signatures, as well as nitrogen concentrations. Wetlands exhibit stronger signals of human-driven alterations to the cycle of nutrients, probably linked to agricultural practices. Dry grasslands show smaller, atmosphere-driven changes. The effects of anthropogenic carbon and nitrogen on macronutrient cycling depend on habitat and species.
