Abstract

Colonies were found to be abundant on seagrasses in the N Gulf of Mexico from mid to late fall through winter. Populations increase in mid to late fall, roughly with the onset of cooler weather. They decline between midwinter and early summer, apparently when cold fronts pass. No colonies were found on seagrass in summer, but some large colonies attached to polychaete tubes lie dormant through summer, regenerating in fall. Spatial variation occurs on very small scales. Absence of B. neritina from patches of seagrass is not the result of poor survival of post-settlement individuals, but rather is likely due to poor dispersal of the lecithotrophic larvae. Local extinctions of Bugula population..
