  1. The log-transformed optical density (OD) is a measure of the anti-Borrelia IgG response and was modelled as a linear mixed effects model. Fixed factors included study area (S), age group (A), and capture year (Y), and the random factor was bear identity. Shown for each model are: the model rank (Rank), the structure of the fixed effects, the degrees of freedom (df), the log-likelihood (LL), the corrected Akaike information criterion (AICc), the difference in AICc value from the top model (Δ AICc), the model weight (Weight 1), and the cumulative weight (Weight 2)
