The establishment of exotic game fishes to enhance recreational fisheries through
authorized and unauthorized stocking into freshwater systems is a global phenomenon …

This paper reviews evidence for and possible consequences of top—down control in the
pelagic Baltic ecosystem. Two top—down control processes, cod predation on clupeids and …

We performed whole—lake manipulations of fish populations to test the hypothesis that
higher trophic levels regulate zooplankton and phytoplankton community structure, biomass …

Understanding the relative importance of top-down and bottom-up regulation of ecosystem
structure is a fundamental ecological question, with implications for fisheries and water …

Based primarily on data collected over the past four decades by Environment Canada, long‐
term trends of eutrophication‐related variables are developed for the offshore waters of the …

For freshwater pelagic ecosystems, the biodiversity and cascading trophic interaction
theories both predict that decreased piscivore populations will result in direct, short—term (a …

Stephen R. Carpenter and James F. Kitchell here is no common currency for ecological
interactions. For example, the consump-tion of a small fish by a larger one entails all the …

The impact of Man on the Baltic ecosystem in the 20th century is summarized by estimating
changes in major energy flows, expressed as organic carbon. Recent eutrophication has …

Environmental Ecology: The Impacts of Pollution and Other Stresses on Ecosystem Structure
and Function deals with environmental studies on the ecological impacts of anthropogenic …

At times, freshwater zooplankton consume phytoplankton populations at rates similar to or
faster than that at which they are growing (Hargrave and Geen, 1970; Gulati, 1975; Hom …
