Other claims from this paper (10)
- Intervention effect Elevated CO2 increased the forest-floor carbon sink by 52 ± 16 g C·m−2·yr−1.
- Association The CO2-induced carbon sink was associated with greater litterfall inputs.
- Association The CO2-induced carbon sink was associated with greater fine-root turnover inputs.
- Intervention effect Elevated CO2 did not measurably alter microbial decomposition.
- Observation Mineral-soil carbon increased under both CO2 treatments.
- Observation Mineral-soil nitrogen increased under both CO2 treatments.
- Intervention effect Elevated CO2 had no detectable effect on bulk mineral-soil carbon and nitrogen.
- Intervention effect Elevated CO2 significantly decreased soil organic carbon δ13C.
- Observation Pools receiving large annual carbon inputs had short mean residence times.
- Observation Slow-turnover pools received small annual carbon inputs.
