In this book, a multidisciplinary research team tests this idea by manipulating whole lakes experimentally, and coordinating this with paleolimnological studies, simulation modeling, and small-scale enclosure experiments. Contributors describe consequences of predator-prey interactions, behavioral responses of fishes, diel vertical migration of zooplankton, plankton community change, primary production, nutrient cycling and microbial processes. Paleolimnological techniques enable the reconstruction of trophic interactions from past decades. Prospects for analyzing the interaction of food web structure and nutrient input in lakes are explored.
