Figure 4. Alert distance of lionfish to an approaching diver on culled and unculled coral reef patches.

Larger distances denote increased wariness. Culled patches are shown by open bars (n = 17 lionfish) and unculled by shaded bars (n = 21 lionfish). Medians (thick horizontal lines), first and third quartiles (boxes) and 95% confidence intervals (whiskers) are shown, along with an outlier (point).
