The diamonds are ploted for values of first settlement day and total cumulative settlement among twelve settlement plates monitored over 140 consecutive days in 2006.  The negative correlation suggests two possible explanations: first that larval supply is variable between the haphazardly located settlement plates spaced over Gardiner beach in Woods Hole.  Alternatively, barnacle larvae exhibit settlement behavior that descriminates between these settlement plates, though the surface of plates are standardized to minimize the contact based habitat cues to barnacle larvae.  It is likely some combination of these two factors, as indicated by various other lines of evidence.
