FIG. 1.

Behavioral responses to conspecific (A, C) and L-cysteine (B, D) odorants following Cd exposures. Percent time juvenile coho spent in the arm of a two-choice maze receiving conspecific odorant or L-cysteine odorant before exposures (Pre exp.), after exposure (Post exp.), and after a 16-day depuration (Depuration). All data represent mean ± SEM of n = 24 individuals. Asterisks indicates statistically significant differences between pre-exposure and post-exposure/depuration behaviors within exposure groups (*P ≤.05).
