Zooplankton community structure of two marginal lakes of the River Cuiabá (Mato Grosso, Brazil) with analysis of Rotifera and Cladocera diversity.
In the present study, two small lakes on the margins of the River Cuiabá were analyzed regarding taxonomic composition and population densities of the zooplankton. Diversity was evaluated for two… Expand
Post-encounter vulnerability of some rotifer prey types to predation by the copepod Acanthocyclops robustus
Prey characteristics affecting vulnerability of a number of rotifer species to the predator Acanthocyclops robustus were investigated. Body volume was the main feature affecting the probability of… Expand
Growth potential of Daphnia magna Straus in the water of dairy waste stabilization ponds
The waters from two ponds of a series of waste stabilization ponds treating dairy effluent, were studied as a growth medium for Daphnia magna Straus individuals in the laboratory. Body growth and… Expand
Growth of the rotifer Brachionus calyciflorus pallas in dairy waste stabilization ponds
Abstract The phytoplankton and zooplankton populations of a series of temperate region waste stabilization ponds treating dairy effluent were studied over a period of 17 months. The system was… Expand
Some aspects of vulnerability to cyclopoid predation of zooplankton prey individuals
The predation cycle (encounter, attack, capture and ingestion or survival) by adult female Acanthocyclops robustus was observed for four crustacean prey types. The chief defense of A. robustus… Expand
