Time-dependent development of cellular dynamics in bioconvection

Abstract

Bioconvection is a non-equilibrium dynamics displayed by directionally moving microorganisms. As a first step towards understanding of cellular dynamics of bioconvection, I developed a system of inverted bioconvection. I previously reported that the establishment of bioconvection proceeds via several distinct states. In the present study, I developed a method to follow individual cells within crowded cellular layer, and analyzed time-dependent development of cellular dynamics.
