Figure 1. Relative diver effects – fixed distance and immediate return.

Relative diver effects on estimated reef fish densities comparing counts over a fixed distance 50 m transect and counts along the tape immediately after deployment. Values indicate the proportional decrease in abundance; asterisks represent significant differences using a Bonferroni corrected alpha-value (p<0.006). The parrotfishes formerly in the family Scaridae are now a distinct lineage within in Labridae [56].
