A field test of the dilution effect hypothesis in four avian multi-host pathogens
Fig 2
Leverage plots showing the relationships between Leucocytozoon prevalence in house sparrows from the 45 localities included in this study and A) avian richness (estimated from a rarefaction curve) and B) mammal density (sum of the densities of all mammals detected at each locality). The prevalence of Leucocytozoon was calculated using the least squares means of a GLM controlling for birds’ ages and locality. The 95% confidence level interval is shown in grey.
