Prevalence of Bd infection across amphibian communities and populations.

aLICA only are wetlands where we detected only L. catesbeianus populations; co-occurring wetlands are those where we detected the presence of both L. catesbeianus populations and at least one other native amphibian population, native only are wetlands where we detected populations of at least one native amphibian species but no L. catesbeianus individuals.
bWetlands were designated Bd+ if at least one sample collected from the wetland tested positive for Bd. The site level prevalence is the proportion of sampled wetlands of each wetland community type with at least one individual that tested positive for Bd.
cThe species level prevalence is the proportion of sampled individuals of each species that tested positive for the pathogen Bd at each of the different wetland community types.
Prevalence of Bd infection determined from all amphibian populations at the 36 wetlands in the three different wetland community types from which we collected population level Bd data. The North American bullfrog (L. catesbeianus) was the only non-native amphibian species encountered, while tiger salamanders (A. tigrinum), Woodhouse’s toads (A. woodhousii), and western chorus frogs (P. triseriata) are all native amphibian species in the Colorado study system. We were able to obtain population-level Bd estimates data from only one population of Northern leopard frogs (L. pipiens), and therefore we did not include this species into our analysis. See Table S3 in File S1 for further detail about Bd infection in L. pipiens in our study.
