Abstract
We describe the behaviour of motile microorganisms (e.g. flagellates) attracted by ''gyrotaxix'' to a sinking, non-motile particle (e.g. an algal cell). The model is based on the application of Stokes' solution for the flow field around the settling cell. The volume within which the flagellate is attracted to the sinking particle is determined from the trajectories of the flagellate. The model of gyrotaxis has severa l applications; these include the colonization of sinking marine snow particles with motile microoganisms and suspension feeding by protozoa .
