Within-population variability in dispersal rules depends upon spatio-temporal prey dynamics.

<p>As well as determining the mean dispersal rules, the underlying prey dynamics influence the emergent heterogeneity in dispersal rules. (A) The standard deviation in the emigration probability across a range of prey <i>r</i>. (B) The standard deviation in the intercept of the reaction norm that determines the stopping probability as a function of prey per predator. All parameters values are as for <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0054453#pone-0054453-g003" target="_blank">Fig 3</a>. Note that where there are missing values it is due to the predator populations always going to extinction; this occurs when prey <i>r</i> and <i>c_step</i> are both high.
