(a) Host diversity (Shannon-Wiener index ±s.e.m.) in the high (dark grey) and low (light grey) resource environments for the three different dispersal treatments. Dotted lines were used to guide the eye highlighting host diversity levels in high (dark grey dots) and low (light grey dots) resource environments in the absence of dispersal. (b) Population resistance against reference phages as a proxy for bacterial resistance against the wild-type T3 phage. Bar length gives the average population resistance for each dispersal treatment. Phenotypes have been grouped according to their average resistance against the reference phage, and the partitioning of each bar indicates the contribution of each group to the mean population resistance.
