Diagram (top view) of the tank used for the detour test. Measurements are in cm. Not to scale.
Figure 2.
Relative lateralization (A) and absolute lateralization (B) (mean±SE) in each treatment: C-CO2/C-Temp (Black bar), E-CO2/C-Temp (white bar), C-CO2/E-Temp (dark gray bar) and E-CO2/E-Temp (light grey bar).
Significant differences between treatments (post–hoc test) are indicated by letters.
Figure 3.
Relative frequency distributions of LR in C-CO2/C-Temp (black bars) and E-CO2/C-Temp (white bars) (A) and in C-CO2/E-Temp (dark grey bars) and E-CO2/E-Temp (light grey bars) (B).
Positive and negative values indicate right and left turns, respectively. The extreme values of |100| indicate fish that turned in the same direction on all 10 trials.
