Data from "More extinction driven by the Red Queen in smaller habitats"

We hypothesize that decreased habitat size exacerbates the asymmetry of evolutionary potential between antagonistically coevolving partners, with greater probability of extinction. This hypothesis was experimentally tested using a model-bacterium-phage system. Data file "habitat.size.extinction-phage.persistence" gives frequency of phage persistence in three types of habitats. Data file "habitat.size.extinction-phage.infectivity" gives the infectivity range of persistent phage populations. Data file "habitat.size.extinction-bacterial.density" gives density of bacterial populations coevolving with phages.
