| 内容記述 | In order to study the interactions in a model aquatic microcosm, an individual-based computer simulation model was developed. The microcosm consists of Euglena gracilis as an autotroph algae, Tetrahymena thermophila as a heterotroph protozoa and Escherichia coli as a saprotroph bacteria. It is a strong interaction between Tetrachymena and E.coli as the first is the predator of the second. Ecological toxicity test were conducted to test the population level impacts of the biological effects of radiation and toxicants on the lethality and mobility factors that influence directly or indirectly grown and reproduction. Radiological effects on lethality of E.coli individuals were translated to the reduction of the equilibrium population of Tetrahymena. A synergistic effect was also observed by the simulation at the community level in the case of combined exposure of radiation and a toxicant which reduced the feeding efficiency of Tetrahymena. | |||||
