  • Stable isotope ratios (d13C and d15N) were measured in archived scale samples of seven fish species captured in Sparkling Lake over the period 1981 through 2009. Stable isotopes of benthic and pelagic food web end members (macroinvertebrates and zooplankton, respectively) were also measured. Zooplankton were from samples taken in Sparkling Lake, Allequash Lake, and Big Muskellunge Lake. Zoobenthos were from samples taken in Sparkling Lake.
