For figure 3: the equations for piscivores should have '+' signs in front of the intercept terms not '-' signs, the equations in the caption for figure 3 should read the following:

The dotted line and open circles represent stream piscivores: log₁₀ prey length (mm) = 1.17 log₁₀ predator length (cm) + 0.051 (n = 13, P < 0.0001, r² =0.81).

The solid line and open squares represent lake piscivores: log₁₀ prey length (mm) = 1.04 log₁₀ predator length (cm) + 0.33 (n = 60, P < 0.0001, r² = 0.65).

The broken line and open triangles represent ocean piscivores: log₁₀ prey length (mm) = 0.96 log₁₀ predator length (cm) + 0.25 (n = 20, P < 0.0001, r² = 0.66).

For figure 2: the final equation should have an intercept term of 16.74, not 17.81, producing the correct length of 30.8 cm for the 0.5 probability.

Logit(p) = 11.25 log10 salmonid length (cm) – 16.74, n =196, P < 0.0001.
