Outline of Final Research Achievements

In order to understand the structure and function of ecosystems, we developed diverse mathematical modeling. [1] Considering gene-expression and hormonal dynamics, we explored new models of adaptation and evolution, including those on temperature dependent sex determination of reptiles, rarity of bidirectional sex change, density-dependent migration of insects. [2] We developed a series of models for the rate of speciation in geographically structured habitats. [3] We studies coupled social/ecological dynamics on mitigation of illegal logging in tropical forests by profit-sharing, and long-range migration of Mongolian herders.
