  1. Comparison of six a priori models of parasitemia in house finches from shrubland sites of different habitat quality at the “Ixtlera” region of northern of San Luis Potosi, Mexico. Abbreviations: k number of parameters, AICc Akaike information criterion adjusted for small sample sizes, ΔAICc Akaike differences, wi Akaike weights. H_q Habitat quality, SMI body condition index, proximity = distance from nearest water source. Null = a null model with only an intercept, but no explanatory variables
  2. * Indicates interaction term
