英文摘要
We have done a watershed-level study of the relationship between carbon cycling and ecosystem structure using the measurement of carbon-14 concentrations (Δ^14C value) and nitrogen isotope ratios of individual amino acids. Δ^14C value indicated that carbon source of river food web was both sequestered carbon from watershed and ambient CO_2. The contribution of both pathways depended on the relative importance of algal production (in-stream production) and terrestrial litter input.
