Thrush Lake, Minnesota, was treated with limestone in 1988 to evaluate the efficacy of protective base addition against the loss of sport fisheries in a sensitive, mildly acidic lake. Prior to treatment, the lake was stressed (pH 6.46, ANC 64 μeq/L)

We examined the trophic roles of two nonindigenous species, ruffe (Gymnocephalus cernuus) and white perch (Morone americana), in the food web of a western Lake Superior coastal wetland, using stable isotope techniques. The δ15N signature of ruffe wa
