Regional Impacts

Ecological ImpactCompetition
In Tampa Bay, A. amphitrite strongly affected the composition of the fouling community, mainly by creating additional structure for the recruitment and colonization of motile species. Removing barnacle shells inhibited recruitment, while adding barnacle shells increased recruitment (Bros 1987).
