| Outline of Final Research Achievements |
Light and nutrients are the essential resources for algal growth. The unidirectional supply of light, combined with self-shading and nutrient consumption, creates opposing vertical gradients of the two essential resources. I investigated vertical pattern formation of phytoplankton and an algal mat. The theoretical results include diversification of phytoplankton light-nutrient competitive traits through light-nutrient competition, and vertical segregation of species through self-organization of an algal mat via light competition. I also investigated the vertical distribution and community composition of phytoplankton species in Michigan lakes through the analysis of data on vertical distributions of phytoplankton species, light, nutrients, and turbulence.
