Table 2
Performance of linear and generalized linear mixed models (sector and null models) to explain the variation in the prevalence and intensity of each group of parasites according to different predictors in fixed effect (age, sex, body mass, Julian date and sector) and in random effect (year of capture and individual identity). The best model (in bold) is the model reflecting the best compromise between accuracy and complexity of the model. ΔAICc is the difference in AICc between the two models.
