Changes in the Population Dynamics of Gammarus tigrinus SEXTON (Crustacea: Amphipoda) as Expression of Sublethal Effects by Reciprocal Interactions of Temperature and Cadmium Enriched Food The population dynamics of Gammarus tigrinus SEXTON were studied in a flow‐through system under semi‐natural conditions over a period of 9 months. Elevated temperatures and Cadmiumenriched food alter lifespan of generations, growth rate, number of individuals and time to reach maturity, even before elevated Cadmium concentrations can be detected in the animals. Reciprocal interactions of Cadmium intake via food and/or water can be modified by the experimental design, because it depends on the experimental animals, on the Cadmium concentration and on the temperature regime with constant or cyclic conditions.
