MODELECOSYSTEMS IN MARINE SCIENCE: A SURVIVING TRACE OR A PERSISTENT INSTRUMENT?
 
During more than three decades of research, marine modelecosystems have been used to examine a variety of scientific questions. A trend in the evolution has been a decrease in size and complexity, and the limitations in volume capacity have more or less excluded research on fish biology and other organisms of similar size. Instead a growing interest has been devoted to the construction of inexpensive and simple equipment designed for studies on nutrient cycling, oxygen dynamics, and food web interactions. Both basic and applied knowledge have been produced from studies in marine modelecosystems. Miniture replicates of aquatic ecosystems are still relevant for a number of ecological and ecotoxicological studies. Major constraints include reduced mixing, biased sedimentation rates, wall effects, and risk of wind-induced damage. Considering the limitations in terms of volume and wall effects, modern modelecosystems are well suited for studies on microbial ecology including ressource utilization, diversity, modelling, bentho-pelagic couplings, and risk assessments of contaminants.
