Table 1.

Species‐level trait predictors used to model amphibian Batrachochytrium dendrobatidis infection prevalence (N = 302 species) and infection intensity (= 139 species), and for assessing disease strategies of amphibians in epizootic sites (= 122 species). The predicted positive (+), negative (−) or neutral (=), associations of each trait to avoidance, resistance and tolerance disease mitigation strategies is indicated
