What is the origin of the European marine non-indigenous species?
Friday, 8 June 2018
A new study of European Alien
Species Information Network (EASIN) identifies the origin (native distribution
range) of the marine non-indigenous species established across the European
Seas (824 species), and the primary pathway of their introduction, based on the
data of the EASIN.
The vast majority of the marine non-indigenous species originate from
the Western and Central Indo-Pacific, in particular for species introduced in
the Eastern Mediterranean.
A significant number of species originate from the Temperate Northern
Pacific, NE Atlantic and Tropical Atlantic, in particular for species
introduced in the Black Sea, Great North Sea and Western Mediterranean.
Time trends reveal a general decrease
in species introductions originating from the Temperate Northern Pacific.
The assessment of the origin and
the associated pathways of the marine non-indigenous species can support
tailored management of specific pathways per marine European region, focusing
to prioritization efforts.
