Infection prevalence and intensity over the field survey period, November 2010–July 2012. a Proportion of A. crepitans infected with Bd is on the primary y-axis (black), and number of individuals captured each month is on the secondary y-axis (grey). Error bars indicate 95% confidence intervals. b Mean infection intensity of A. crepitans across months, measured as log transformed zoospore equivalents of only infected individuals and the error bars indicate standard error. c Infection intensity of all species collected, averaged and including the negative samples. Error bars indicate standard error. Numbers at the base of the bars represent the number of animals that tested positive over the total number of animals sampled
