Mediterranean marine biodiversity is undergoing a tropicalization process.We present
the first record and spread dynamics of the tropical green seaweed Halimeda incrassata (Bryopsidales,
Chlorophyta) fromthe Mediterranean Sea. Plants were observed at 2 sites offMallorca island
(NW Mediterranean), and species identification was confirmed molecularly. Since the first observation
of this alien seaweedin 2011, it has spreadrapidly inthe shallow subtidal habitat ofamarine protected
area located in Palma Bay, which has a depth of up to ca. 20 m. By 2015, this species spread
by a factor of 6.75 and extended to an area of 2.7 km2, covering a total of 41% of the monitored area.
The dynamics of the invasion suggest rapid colonization and establishment and spreading of the
species through shallow sedimentary and rocky habitats. H. incrassata has the potential to strongly
alter the ecosystem services and functioning of shallow Mediterranean habitats. We encourage
authorities to pay attention to the spread of this alien seaweed at larger scales and determine the
positive and negative effects of the invasion in order to facilitate research- driven decision making.
