Description

To evaluate the possibility that density-associated effects modulate octocoral abundance on a Caribbean coral reef, we tested the hypothesis that the density of octocoral recruits (colonies <= 4 cm tall) and adult colonies are positively associated on shallow reefs (<=14 m depth) in St. John, US Virgin Islands. Both life stages were censused for density at 8-10 sites along 7 km of shore in 2013 and 2014, and a correlative approach was used to evaluate the extent to which the densities were associated using sites as replicates.
