Bacteria and Taylor’s Law

In this paper we show how different stress factors and genetics affect the prediction between mean and variance in population density (Taylor’s Law).  Indeed, we find an exponent close to the oft cited default value of 2. This opens exciting prospects for understanding how environment and evolution contribute to large scale population patterns.
