In the present investigation, nutrients (nitrogen and phosphorus) and planktivorous fish just over 1 year old were added to enclosures in a 2x2 factorial design. In this way, nutrienteffects could be distinguished from “top down" effects of the fish. Results were compared to other lakes with known levels of planktivorous fish"--Executive summary. |
