The concept of cascading trophic interactions predicts that an increase in piscivore biomass
in lakes will result in decreased planktivorous fish biomass, increased herbivorous …

We reared Daphnia pulex in a fully defined medium at seven calcium (Ca) concentrations
(0.1, 0.5, 1, 1.5, 2, 5, and 10 mg Ca L− 1), two mixed algal densities (high food: 30 mg …

Bythotrephes longimanus is an invertebrate predator that has invaded the North American
Great Lakes and a number of inland lakes, where it preys on crustacean zooplankton. We …

In nature most organisms have to manage conflicting demands of food gathering, predator
avoidance, and finding a favorable abiotic environment (oxygen, temperature, etc.) in order …

Limnologists have long recognized the importance of predation in freshwater communities.
The majority of study of predator effects has involved vertebrate predators, with emphasis on …

We developed a new simulation model approach to estimating secondary production of
Chaoborus in order to determine the pathways and rates of energy flow between …

Columbia River reservoirs support a large population of nonnative American Shad Alosa
sapidissima that consume the zooplankton that native fishes also rely on. We hypothesized …

Zooplankton in Lake Tiga was identified and its community structure assessed between
March 2009 and March 2011. A total of 54 species of zooplankton was recorded, comprising …

This paper assesses the feeding demand of planktivores in Lake Pend Oreille in relation to
crustacean zooplankton food availability. The copepods Diacylops bicuspidatus thomasi …

Historic metal mining and smelting in the area of Sudbury, Ontario, has resulted in lakes with
elevated levels of metals in the sediment, low inputs of terrestrial organic material, and …
