  1. We report the proportion of bats with positive detections of Pseudogymnoascus destructans (Pd) detected by qPCR (Pd Prevalence by qPCR, the proportion of bats with signs of Pd infection from histological examination (WNS Prevalence histology) and by fluorescent cutaneous infection visible by ultraviolet light (WNS Prevalence UV). We report the mean Pd load in attograms with standard error in parentheses; asterisk (*) indicates a single estimate in some groups. For bats that could select a temperature or humidity during the experiment, individuals that spent > 89% of captive days in a chosen temperature or humidity were assigned to a treatment group, otherwise they were assigned to an inconstant group representing variable conditions.
