From left to right: Parameter of the predictor variable, parameter estimate, estimate standard error (SE), z-value and P-value. In the parameter column, the ZI-intercept is the intercept of the zero-inflated part of the model. In the random effects column, \({\tau }_{00 Site}\) is the group variance, \({\sigma }^{2}\) the residual variance, ICC the intraclass correlation coefficient, and \({N}_{Site}\) the levels of the random factor. Autumn, female and no presence of ticks and/or lice are the baseline categories for the categorical explanatory variables
