From regional or thematic species database
Introduced species abundance United Kingdom part of the Irish Sea and St. George's Channel (Marine Region): Locally common [details]

Introduced species impact United States part of the North Atlantic Ocean (Marine Region) Outcompetes native species for resources and/or space:
Taken together, these characteristics demonstrate that D. vexillum is an effective competitor, particularly when it comes to occupying open substrate in areas with low propagule pressure (such as new or recently cleaned aquaculture equipment). However, it is not the ultimate competitor with superior resistance to predators, as was suggested by early observational data of newly discovered populations. [details]

Introduced species impact in Canadian part of the Bay of Fundy (Marine Region) : Other impact - undefined or uncertain [details]

Introduced species impact in United Kingdom part of the English Channel (Marine Region) : Outcompetes native species for resources and/or space [details]

Introduced species impact New Zealand part of the South Pacific Ocean (Marine Region) : Loss of aquaculture/commercial/recreational harvest or gain [details]

Introduced species impact United States part of the North Atlantic Ocean (Marine Region) Alters trophic interactions:
We show non-native species facilitate native predator population growth by providing a novel temporal resource that prevents loss of predator biomass when its native prey species are rare. [details]

Introduced species impact United States part of the North Atlantic Ocean (Marine Region) Outcompetes native species for resources and/or space:
D. vexillum appears to be the key driver of biodiversity decline in the epibenthos when present, rather than other processes such as direct disturbance and extraction from dredging. This research evaluates ecological responses to the presence of an invasive tunicate and suggests that this invasive species is a major force in shaping the ecological interactions in invaded areas. [details]

Introduced species remark New Zealand part of the South Pacific Ocean (Marine Region) : Didemnum vexillum is considered a major threat to New Zealand's mussel industry because of its demonstrated invasiveness on artificial structures, and its ability to over-grow and smother mussels (Coutts and Forrest 2007). [details]

Introduced species remark New Zealand part of the South Pacific Ocean (Marine Region) : D. vexillum is considered a serious and persistent fouling pest to their commercial shipping industry and ports (Coutts and Forrest 2007).  [details]

Introduced species remark in United States part of the North Atlantic Ocean (Marine Region) : This paper does not represent a new record but establishes the invasiveness of the species at this location.  [details]
