About invasive seaweeds

Introduced seaweeds represent one of the largest groups of marine aliens in Europe, and are shown to constitute between 20 and 29 % of all alien marine species. Seaweeds are major primary producers in coastal areas, and are extremely important for coastal ecosystems by supporting high biodiversity through structuring complex habitats for associated species. Large-scale substitution of dominant native seaweeds with alien species will consequently alter coastal productivity and food web structure, and therefore impact ecosystem service.

The project focuses on certain target species which have been introduced to Europe.
