Abstract

Carbon and nitrogen stable isotopes were applied as naturally occurring tracers in determining the trophic relationships of different organisms in the pelagic food web of Lake Ontario. Particular attention was given to understanding how biogeochemical processes influenced the isotope signatures of primary producers and consumers at the base of the food chain and how isotope signatures at the baseline varied seasonally.
