Logarithm of the ratio of lysogenic to susceptible bacteria during competitions in structured environments.

<p>Initial ratios were 1∶10⁴, 1∶10⁻², 1∶1, and 10⁴∶1. Lysogenic cells include original lysogenic cells and their descendants (streptomycin-resistant) as well as lysogenized susceptible cells (rifampicin-resistant) and their descendents. Each data point represents the mean value of three independent values.
