SUPPLEMENTAL FIGURE 5: Density plots of infection severity as indicated by degree of orange fluorescence under ultraviolet light in bats from the historical and contemporary translocation experiments in Extirpated (Warm + Wet). A UV score of 0 = no orange fluorescence indicative of infection, 1 = 1-10% of wing area displays orange fluorescence, 2 = 10-50% of wing area displays fluorescence, and 3 = 50-100% of wing area displays fluorescence. Following mortality, bats in the historical experiment were histologically examined and infection severity scored using the following scale: 0 = no fungi suggestive of WNS, 1 = superficial and limited but suspicious of early WNS with hyphae in keratin and randomly into epidermis, but not yet forming distinctive cupping or dense packets, 2 = more extensive superficial infection with epidermal cupping packed with hyphae diagnostic of WNS, 3 = more severe fungal infection with tissue invasion including epidermal cupping packed with hyphae diagnostic of WNS, 4 = severe infection with tissue and wing damage worse than 3. To estimate UV score from the historical dataset, we assigned histology scores of 0 and 1 a UV score of 0, scores of 2 a UV score of 1, scores of 3 a UV score of 2, and scores of 4 a UV score of 3. Tissue does not display orange fluorescence until infection has been well established, and a histology score of 2 likely corresponds to when fluorescence will first be detected. Dashed lines correspond to the mean UV scores in each dataset.
