Effect of covariatesa on detection probability ().

Note: Model rankings are based on Akaike’s Information Criterion (AIC).aCovariates used to model detection probability were Block (B), Substrate (sandy streambeds, roads and trails) and Effort. ‘.’ denotes that was held constant instead of being allowed to vary as a function of any covariate.bIn all models the probability of occupancy () was modelled on ‘B × Hab’ and segment level occupancy parameters ( and ) were modelled on ‘B’ (Block). ‘+’ denotes covariates were modelled additively.
