Population outcome across all 7,098 parameter combinations (Table S2). To illustrate the main effects, we plotted each parameter of interest against the proportion of population outcomes while not holding the other variables constant. Results are shown for (a). the number of host genotypes, selected randomly from a uniform distribution of GSM values spanning 0–1, (b). transmission, in maximum metres of distance that a zoospore can travel from infected to uninfected individuals (in a 100 × 100 m environment), (c). adult carrying capacity and (d). tadpole carrying capacity. Adult carrying capacity, transmission and the number of genotypes have noticeable effects on population outcome, while tadpole carrying capacity has little to no effect
