| Research Abstract |
Ecosystems have been analyzed focusing on their matter and energy flows. In this study, we explore novel theories explaining how the evolution and adaptation of each species forming regularity in the whole system, producing emergent pattern and stability, the species diversity maintained in the system, and life history tactices of divers organisms. Especially we developed a novel theoretical frameworkin understanding how ecosystem dynamics and human hehavioral choices are coupled and derived a new formula for how the number of species in isolated forest fragment or islands decline over many years.
