AbstractStable isotope signatures of freshwater snails and mussels have been established as a convenient baseline measurement at the primary consumer level for food-web coupling studies. We measured delta(15)N and delta(13)C of primary consumers, including mussels (Anodonta woodiana, Cristaria plicata, and Unio douglasiae), snails (Bellamya aeruginosa and Hippeutis sp.), and zooplankton from the same habitat within a shallow eutrophic lake. Primary consumers showed positive relationship between delta(15)N and delta(13)C, indicating a linkage between planktonic and benthic habitats in this system. The variation in isotope ratios was higher in short-lived primary consumers (zooplankton) compared with the long-lived primary consumers (mussels and snails), suggesting limited availability of short-lived primary consumers as isotopic baselines in aquatic food-web assessment. Significant differences in isotope ratios were also found among three species of mussels, and when using these mussels separately as pelagic baselines to calculate trophic position and contribution of planktonic and benthic sources of fishes, bias and even misestimates were observed. This finding suggests that caution is needed when multiple primary consumers coexist in the same habitat, and it is important to assess potential effects of different baselines used.
