Wavelengths of Gyrotactic Plumes in Bioconvection [PDF]
Bulletin of Mathematical Biology, 2000 Bioconvection occurs as the result of the collective behaviour of many micro-organisms swimming in a fluid and is realized as patterns similar to those of thermal convection which occur when a layer of fluid is heated from below. We consider the phenomenon of pattern formation due to gyrotaxis, an orientation mechanism which results from the balance of
