Figure 7 in Manatee behavioral response to boats

Figure 7. Model-estimated mean probability (solid line) of a manatee making any change in behavior (roll, heading, depth, or fluking) as a function of boat pass duration (6 95% confidence bounds shown as dashed lines). The fixed factor values used to generate these estimates are listed in Table 3. A frequency histogram of observed boat pass durations is shown at the bottom. There were 32/346 boat passes (9.2%) longer than 120 s that are not shown here.
