FIGURE 3.

The (a) proportion of wing tissue displaying signs of infection with Pseudogymnoascus destructans and (b) amount of weight lost over hibernation in bats from each site. Black points and error bars represent model estimates ± standard error. Tissue invasion at Extirpated (Warm + Wet) was higher than that at the similarly humid Persisting 2 (Cold + Wet), suggesting that the higher fungal growth rate at the extirpated site resulted in greater tissue invasion and ultimately higher weight loss. The low humidity conditions at Persisting 1 (Cold + Dry) may have driven the observed increase in tissue invasion despite a lower pathogen growth rate. Low humidity conditions can exacerbate evaporative water loss from infected tissue, which may have increased arousal frequency and weight loss
