Figure 4: Comparison of vertical migration behavior in 2005 trials versus 2007 trials using larvae of similar ages showing the percentage of nondemersal larvae as a function of time of day. Data collected in 2007 were reanalyzed by converting to % nondemersal in order to make the datasets comparable. Shading indicates timing of light cycles. Light grey shading indicates darkness in 2005. Dark grey shading indicates darkness for both years. Error bars represent ± 1 SE.
