Detailed coverage of invasive species threatening livelihoods and the environment worldwide

Abstract

New records of the non-indigenous species Branchiomma bairdi and B. conspersum (Polychaeta: Sabellidae) on the Pacific coast of North America.

Abstract

Among Sabellidae (polychaetes commonly found in hard substrate fouling communities), the genus Branchiomma Kölliker is a species-rich group with an expanding global history of invasions. In this paper, we report the first new records of Branchiomma bairdi along the Californian and Hawaiian coasts. Moreover, we confirm the first recorded introduction and range extension of Branchiomma conspersum. Branchiomma conspersum is originally from the Caribbean Sea and is a new non-indigenous species on the Pacific side of Panama and is also present in Hawaii and Australia.
