Estimated probabilities of Bd persistence, Bd clearance and host extinction, as functions of and μZ in the deterministic model, shown as colour codes. Pure colours green, magenta and blue correspond to 100% Bd clearance, Bd persistence and host extinction, respectively. Mixed probabilities appear as compound colours. (a,b) Zo > 0. (c,d) Zo = 0. (a,c) Tadpoles suffer from infection. (b,d) Tadpoles tolerate Bd. All other model parameters were sampled within their entire range, as described in the electronic supplementary material, §5.2. Similar results were obtained for the stochastic model.
