Figure 4

Relationship between mass-specific residuals of rate of change in conductivity (Δ Ci; µS g h−¹) and infection intensity [Log (ZE + 1)] of L. caerulea during (A) the intermoult and (B) mid-slough periods. Grey circles (
) represent uninfected animals and red gradient circles (
) represent infected animals. Horizontal line denotes mean residual. Correlation between mass-specific Δ Ci and infection intensity is 0.38 with a regression line of Ci = 0.14 (ZE + 1) − 0.06 for the intermoult group and 0.09 with a regression line of Ci = 0.03 (ZE + 1) − 0.08 for mid-slough group. Red area shading around regression line represents 95% confidence interval and data presented as individual points from n = 33 uninfected frogs, n = 15 (intermoult) or 10 (mid-slough) Bd infected frogs.
