File S1 - Investigating Differences across Host Species and Scales to Explain the Distribution of the Amphibian Pathogen Batrachochytrium dendrobatidis

Supporting tables. Table S1, Number (n) of individuals included in the laboratory infection experiment. The starting (n) is the number of individuals of each species that were infected with Bd at the beginning of the experiment. The mortality loss is the number of individuals that died before the beginning of experiment (within the first 3 days post-infection). The number of resistant individuals are those that were infected with either ∼10,000 (low treatment) or ∼200,000 (high treatment) Bd zoospores two times, but did not test positive for Bd either 3 or 6 days post infection. The final (n) is the number of individuals for each species and treatment group from which we obtained data used in our analyses. AMTI is Ambystoma tigrinum; ANWO is Anaxyrus woodhousii, PSTR is Pseudacris triseriata; LICA is Lithobates catesbeianus. Table S2, All models used in model selection to determine the best-supported model predicting 1/0 infection in individuals and quantitative Bd infection load. Predictor variables were either included (1), or not included (0) in each model. Models were ranked according to their AIC (Akaike Information Criterion). The ΔAIC is the difference between each model and the best-supported model. All models with a ΔAIC Ambystoma tigrinum, ANWO is Anaxyrus woodhousii, LICA is Lithobates catesbeianus, and PSTR is Pseudacris triseriata. Table S3, Landscape-level occurrence and site-specific Bd infection data for the five amphibian species encountered in our field study. aThe number of wetlands where each species was detected in our survey of landscape –level amphibian occurrence. bThe proportion of those wetlands included in our survey of landscape-level amphibian occurrence (n = 52), which supported each amphibian species. cIndicates whether or not a species was observed at a given wetland. 1 = species observed, 0 = species not observed. dWe detected at least one individuals of the species L. pipiens at 3 wetlands, though only one supported a large enough population for us to gather a population-level estimate of Bd infection prevalence. Due to the small number of L. pipiens encountered in our field survey, we did not include this species in any analyses investigating patterns of Bd infection across the landscape. (DOCX)
