| Outline of Final Research Achievements |
We investigated the relationship between information processing of Euglena and the hierarchical flow structure caused by individuals and their collective motion. A number density flux was suggested proportional to the intensity of the optical gradient. This result was incorporated to construct a model equation of localized bioconvection. This equation reproduces the localized bioconvection as well as the bistability of the state, which is suggested by the experiments. For flapping flight, we developed a method to describe the behavior of separation vortices in a low-dimensional dynamical system by using the single vortex approximation.
