The prevalence of Bd among stage classes and seasons. The prevalence of Batrachochytrium dendrobatidis (Bd) in the three stage classes of Rana pipiens varies across the three seasons. Shown are the mean prevalence of Bd and the 95% confidence limits. The three stage classes are young of the year (YOY), juveniles, and adults and are separated by the vertical dashed lines. The three seasons are spring, summer, and fall and are abbreviated on the x-axis as L, S and F, respectively. Captures are pooled across all years and both locations (CVWMA, BFWMA).
