  1. aThe structure of the other parameters (initial states, survival, detection, blood collection and age assignment) is the same for all seven models listed in this table (see Additional file 1: Table S1 for the details of the model parameterization for these parameters). The ‘.’ entries (‘dot’) denote an interactive effect, ‘+’ entries denote an additive effect, and ‘&’ entries specify that two or more parameters are equal. Square brackets indicate that the additive effect is applied to all the terms contained in the square brackets. All other competing models, representing various structures for the other parameters, are presented in Additional file 1: Table S1. None of the competing models were supported by the data (ΔAICc > 2)
