Fig. 5. Effect of various concentrations of He-LWamide II and Hydra-RFamide I on
three parameters of migration: the number of active periods per hour (A,D,G),
the length of active periods (B,E,H), and the speed of migration during active
periods (C,F,I). Asterisks indicate results that are significantly different
from the control values (shown in the far-left column in each panel)
(t-test; *P<0.05, **0.01). Sample
size was minimally 50.
