Population of bacteria are often heterogeneous, even though the bacteria are genetically identical and live in the same environment. This heterogeneity represents in fact a strategy aimed at surviving against environmental changes. After describing some biological examples, I will briefly review the existing literature on the subject. Then, I will propose a new scenario, in which environmental changes are characterised by catastrophes (sudden drops in the population size), and the environment is responsive, meaning that its changes depend on the actual state of the population. Finally I will discuss why and when switching can be a good strategy for the population itself.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
