Outline of Final Research Achievements

Regime shifts are increasingly widespread and serious trends in natural ecosystems. Regime shifts have large ecosystem effects and restoration after the shifts is costly and difficult. First, in order to estimate whole-lake primary production theoretically in lake ecosystems with a variety of lake characteristics such as lake morphometry, I studied parameter sensitivity and calibration of phytoplankton productivity between nutrient- and light-based primary production models. Second, I studied restoration management for deteriorated ecosystems by focusing on local ecological problems.
