Host-parasite specialization

This data file contains data on bacterial resistance in two subpopulations linked by migration. Homogeneous subpopulations are linked by 1% dispersal (where treatment A gives dispersal between 0.5-0.5 M9 and B gives dispersal between 5-5 M9). Hetergeneous populations (0.5-5 M9) are linked by either 1% (C) or 50% (D) dispersal. For each subpopulation 5 bacterial clones (A1-A5 and B1-B5) where tested for resistance (1 or 0) against infectivity by 5 phage clones (A1-A5 and B1-B5) isolated from each subpopulation.
