Figure 2 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 2: Relationship between the neutrophil-to-lymphocyte (N:L) ratio and vole density index according to sex. Vole density was estimated as the number of captured voles/100 traps/24 h. Grey shaded areas show the 95 % confidence intervals of the predicted curves.
