| Styela plicata has been the dominant marina fouling organism in southern California harbors since 1960 (Lambert and Lambert 1998). It produced large monospecific patches in several locations during serval years in San Diego Bay (Lambert and Lambert 2003). It and other introduced ascidians have replaced the native species Pyura haustor and Ascidia ceratodes in southern California harbors (Lambert and Lambert 1998). | ||
