Figure 3 in Variation in leukocyte indices and immunoglobulin levels according to host density, sex, flea burden and tularemia prevalence in the common vole Microtus arvalis

Figure 3: Relationships between the proportion of eosinophils and a) vole density (number of captured voles/100 traps/24 h), and b) tularemia and flea prevalence in voles. The grey shaded area shows the 95 % confidence intervals of the predicted curve (a; left) and error bars show standard deviations (b; right).
