  1. aThe Proteobacteria were divided in the classes present, its class Gammaproteobacteria belonged to the most abundant phyla and Proteobacteria classes. bOnly the fixed factors of the final models are presented. cModel with aviary included as random factor. Units of factors: season, summer and winter; sex, female and male; BMR, ml O2∙h−1; body mass, g; and BSA, antibody titre against immune index BSA; residual haemolysis, lysis; and residual haptoglobin concentration, mg ml−1
