Figure 5. Temporal dynamics of the locomotion activity of males (blue solid line) and nonspawners (green solid line) during mass spawning events.

(A) Strongylocentrotus intermedius. (B) Mesocentrotus nudus. The data on the step lengths of males and nonspawners were combined into corresponding time series and aligned on the X-axis at the time point coinciding with the beginning of spawning of the first individual in each mass spawning event. Vertical dashed lines denote the boundaries of the control, prespawning and spawning intervals. Vertical solid lines indicate the interquartile range (IQR).
