Evolutionary dynamics in a varying environment: Continuous versus discrete noise
Ami Taitelbaum, Robert West, Mauro Mobilia, Michael Assaf
Abstract
The evolution of an ideal microbial population consisting of two competing strains, one growing faster than the other, is studied under fluctuating environmental conditions. It is shown that the likelihood for the slow strain to take over the entire population can be greatly enhanced under a continuously varying environment compared to a binary environment, even when the mean and standard deviation of the environmental variations coincide.
