FIGURE 2 in Daily rhythm of locomotor and reproductive activity in the annual fish Garcialebias reicherti (Cyprinodontiformes: Rivulidae)
FIGURE 2 | Daily rhythm of locomotor activity in paired fish of Garcialebias reicherti recorded during four days in LD. A. Representative time series (actograms) and cosinor fit diagrams for two female (orange) and a male (green) dyads. Amount of locomotor activity (number of events) is normalized for visualization purposes. Gray areas in the actogram represent the dark phase of each 24 h period. The cosinor representation for each individual of the dyad is shown next to the actogram. Black outlines represent the duration of the night. The internal circumference depicts the p = 0.05 confidence limit. Radial lines show the extreme values of the acrophases calculated for each of six days. B.

Members of each dyad are presented in the same color. The internal circumference depicts the p = 0.05 confidence limit and length of the black radial line marks the p value (external circumference is p = 0, see main text for p value).
