Outline of Final Research Achievements

The following mathematical models 1)-3) were represented based on data analyzed environmental parameters and benthic community samples in Antarctic lakes.
1) "Modeling photo-chemical reaction": Photosynthetic reaction center of photo-trophs was represented as three-state model, and optimum strategy of light utility was evaluated responding to light wavelength, then the respondence mechanism of photo-trophs was explained theoretically. 2) "Modeling developing process of vertical community structure": Productivity of photo-trophs was evaluated under vertical-space structure, and the formation process of vertical community structure was modeled. 3) "Modeling formation process of vertical pigment pattern": The formation process of vertical pigment pattern which the actual photo-trophs possesses was modeled by responding to incident light spectra to the actual lakebeds.
