- •
DOC biodegradation varied substantially among the Three Gorges' tributaries.
- •
DOC biodegradation ranged from 15.8% to 35.2% with a mean of 24.5 ± 8.0%.
- •
DOC biodegradation was tightly correlated with P concentration and C:P ratio.
- •
DOC biodegradation is limited by P availability in the subtropical rivers.
