| 内容記述 | Conservation of rural ecosystems in execution of agricultural infrastructure improvements and rural development projects is required since the revision of the Land Improvement Act. Preparations of food resource for lives are critical to sustain the ability of facilities to conserve the ecosystem. Food web construction in a canal and a pond were analyzed using the stable isotope ratio method. Carbon isotope ratio (δ13C) of the attached matter in Habahirosuiro, a widened section in a canal, increased during the summer due to the activation of algae production.δ13C in a section covered with a riparian forest was low and static. Insufficient solar radiation may have prevented algal growth. A low nitrogen stable isotope ratio (δ15N) present in chemical fertilizers from paddy fields caused the peak of nitrate nitrogen concentrations to lag behind δ15N. The food web in narai-tsutsumi pond was evidently based on terrestrial organic matter. |
