in an increasingly impounded large subtropical river (the Yangtze): the terrestrial dominance
through internal respiration of land‐derived organic carbon and the influence of increased
autotrophic activity in impounded areas on river pCO2. River pCO2 and total organic carbon
(TOC) increase downstream on the main stem (pCO2: 528–1703 µatm; TOC: 137–263
µmol/L) and vary significantly among tributaries (464–3300 µatm; TOC: 109–340 µmol/L) …
