Abstract:
We report the occurrence of four red
macroalgae new to Europe. Two species were unambiguously
determined to the species level with a DNA
barcoding approach, while the remaining two species
could only be assigned to a genus. Gelidiumvagumwas
found in the Oosterschelde estuary (the Netherlands).
Gracilariopsis chorda, Chondracanthus sp. and Solieria
sp. were found in the Gulf of Morbihan in Brittany
(France); Solieria sp. was also subsequently observed
in the Thau Lagoon (France). Gelidium vagum and
Gracilariopsis chorda are species originating from the
north-western Pacific, around the Japanese archipelago.
Phylogenetic analyses also show a likely Pacific
origin for Chondracanthus sp. and Solieria sp. Three of
these species are likely to have been introduced after
2008, indicating some active transport pathways
between the Pacific and the north-eastern Atlantic.
These findings also underline the importance of
consistent and continuous local expertise (versus rapid
assessment) in early warning systems.
