Hydrodynamic interactions and their role on the dynamics of bacterial predators.

ORAL

Abstract

We consider the effects of hydrodynamics on the behavior of bacterial predators searching for bacterial prey. Experimentally, we find that bacterial predators respond to external flow fields in addition to responding to their own self-generated flow fields neighboring surfaces and finite boundaries. We will discuss the implications of this finding on bacterial hunting strategies.
