 note = {Well-designed experimental model ecosystem could be a simple reference of the actual environment and complex ecological systems. For ecological toxicity tests of radiation and other environmental toxicants, we investigated an aquatic microbial ecosystem (closed microcosm) in the test tube with initial substrates, autotroph flagellate algae (Euglena, G.), heterotroph ciliate protozoa (Tetrahymena T.) and saprotroph bacteria (E.coli) [1].   These species organizes by itself to construct the ecological system, that keeps the sustainable population dynamics for more than 2 years after inoculation only by adding light diurnally and controlling temperature at 25 degree Celsius.  
Objective of the study is to develop the particle-based computer simulation by reviewing interactions among microbes and environment, and analyze the ecological toxicities of radiation on the microcosm by replicating experimental results in the computer simulation., 国際放射線防護学会第11回大会},
