Outline of Final Research Achievements

We have concluded that Carbon/Nitrogen stable isotope ratios could be used for evaluation of ecosystem diversity, and metagenome for evaluation of species diversity. It was observed that distribution of carbon/nitrogen isotope ratio of fish population in irrigation and drainage facilities varied with environment. Variation of both ratios in habitats consisting of varied environment elements was wide. It was considered that variation of the ratios indicated ecosystem diversity. Metagenoe analysis was also illustrated the possibility of use for evaluation of species diversity because its capability was higher than previous cloning method. Adaptation of biological community estimation using metagenome analysis in irrigation and drainage facilities is expected to be a epoch-making method that provide us comprehensive information regarding species diversity.
