Ecological Propagations of radiological impacts in the microbial model ecosystem: A study with computational simulation

Well-designed experimental model ecosystem could be a simple reference of the actual environment with complexity. For ecotoxicological tests of radiation and other environmental toxicants, we made an aquatic microbial ecosystem in the test tube with autotroph flagellate algae, heterotroph ciliate protozoa and saprotroph bacteria. For theoretical analyses on the population and mass dynamics of these microbial species, an individual-based computer simulation model with dynamic energy mass budget theory was developed, and it showed the mechanisms of the synergistic impacts of acute gamma radiation exposures on their population dynamics and mass budgets
