Abstract

Organisms in fluctuating environments must adapt their behavior to survive. In clonal populations, this may be achieved through sensing followed by response, or through generation of diversity by stochastic phenotype switching. We show that stochastic switching can be favored over sensing when the environment changes infrequently. The optimal switching rates then mimic the statistics of environmental changes. We derive a relation between the long-term growth rate of the organism and the information available about its fluctuating environment.
