Adult and YOY density at six primary study sites and within the three broad geographic regions surveyed: North County, La Jolla, and Point Loma.

Maximum YOY density was calculated using the maximum number of YOY recruits observed on a 120 m∧2 belt transect after a settlement pulse. na indicates ‘not applicable’ (i.e. no YOY were present).
aSites not connected by similar letters have significantly different densities (One-way ANOVA F8,638 = 936.9, p<0.00001; Tukey HSD p<0.001).
bTwo replicate belt transect surveys 120 m∧2 (30 m×4 m) were conducted per dive.
cSurveys in broad geographic regions (North County, La Jolla, Point Loma) were conducted between March and June prior to settlement of YOY and consisted of 2–4 belt transect surveys per site.
