marginally insignificantP = 0.069
While a marginally insignificant reduction in the population density of the superior competitor by its phage was observed (Figure 1e–h ; F 1,90 = 3.381, P = 0.069), the population density of the weaker competitor was significantly increased in the presence of phage infecting the superior competitor ( F 1,90 = 4.484, P = 0.037).
