“…For example, Asparagopsis armata was first reported in 1980 from the Chafarinas Islands (Conde Poyales, 1984) but the first Moroccan sighting took place during a series of surveys between 1989-1993, when the species was already widespread all along the Moroccan coastline (González-García & Conde Poyales, 1994). The same trend was ob-served for other species such as Asparagopsis taxiformis, Codium fragile, and Eudendrium merulum Watson, 1985(Altamirano, 1999Peña Cantero & García Carrascosa, 2002). The position of these two regions (Chafarinas Islands and Melilla) at the east end of the Moroccan Mediterranean has certainly contributed to the increase in early detection rates of alien species in these regions.…”

This study provides an updated list of alien marine species that have been introduced to Morocco by analyzing both previous data and new findings. A total of 46 marine alien and 15 cryptogenic and crypto-expanding species were recorded in Moroccan waters. Alien species are more abundant in the Mediterranean (35 species) than in the Atlantic (16 species) waters. The number of records of introductions increased in recent years in Moroccan waters. Macrophyta ranked first in terms of the number of species (19 species), followed by Mollusca (8 species), Crustacea (7 species), Cnidaria (5 species), Pisces (3 species), and Tunicata (2 species), while Nematoda and Annelida each contain only one species. The finding of Phyllorhiza punctata, a new species recorded for the first time in the Moroccan Mediterranean waters, is described. The Moroccan Mediterranean harbors more established species (77%) than the Atlantic (69%), contrary to casual records (25% in the Atlantic and 20% in the Mediterranean). Within Moroccan waters, 12 species have been identified as either invasive or potentially invasive: Rugulopteryx okamurae, Sargassum muticum, Asparagopsis armata, Asparagopsis taxiformis, Caulerpa cylindracea, Codium fragile, Agarophyton vermiculophyllum, Artemia monica, Callinectes sapidus, Caprella scaura, Microcosmus squamiger, and Branchiomma luctuosum. The Transport- Stowaway pathway accounted for 23 and seven records in the Mediterranean and Atlantic, respectively. In the Mediterranean, the second most frequent pathway was Transport-Contaminant (6 species), while in the Atlantic was Escape (4 species). This list serves as a starting point for management measures and for selecting invasive alien species to assess their impact.

“…Asparagopsis taxiformis L2 dominates the central Mediterranean, and the lineage was recently found in the eastern Mediterranean where its behavior is often invasive (Tsiamis et al 2010). In the western Mediterranean, anonymous lineages of A. taxiformis have been previously reported from the archipelago of the Chafarinas Islands since 1999 (Altamirano 1999). The taxon has been since found in the south-eastern coast of Spain, the north coast of Morocco and the Strait of Gibraltar (Altamirano et al 2008, Dijoux et al 2014.…”

The mitochondrial genetic diversity, distribution and invasive potential of multiple cryptic operational taxonomic units (OTUs) of the red invasive seaweed Asparagopsis were assessed by studying introduced Mediterranean and Hawaiian populations. Invasive behavior of each Asparagopsis OTU was inferred from phylogeographic reconstructions, past historical demographic dynamics, recent range expansion assessments and future distributional predictions obtained from demographic models. Genealogical networks resolved Asparagopsis gametophytes and tetrasporophytes into four A. taxiformis and one A. armata cryptic OTUs. Falkenbergia isolates of A. taxiformis L3 were recovered for the first time in the western Mediterranean Sea and represent a new introduction for this area. Neutrality statistics supported past range expansion for A. taxiformis L1 and L2 in Hawaii. On the other hand, extreme geographic expansion and an increase in effective population size were found only for A. taxiformis L2 in the western Mediterranean Sea. Distribution models predicted shifts of the climatically suitable areas and population expansion for A. armata L1 and A. taxiformis L1 and L2. Our integrated study confirms a high invasive risk for A. taxiformis L1 and L2 in temperate and tropical areas. Despite the differences in predictions among modelling

“…This genus is composed of a complex of cryptic species 13 , but only two species are presently accepted, Asparagopsis taxiformis (Delile) Trevisan de Saint–Léon and A. armata (Harvey), both having a cosmopolitan distribution and being well established in the Mediterranean Sea. However, the presence of A. taxiformis in the Southwestern Mediterranean basin is quite recent, as it was observed for the first time in 1999 along the coast of Morocco 11 14 . It is currently suspected to spread rapidly 11 15 .…”

Mediterranean Sea ecosystems are considered as hotspots of biological introductions, exposed to possible negative effects of non–indigenous species. In such temperate marine ecosystems, macroalgae may be dominant, with a great percentage of their diversity represented by introduced species. Their interaction with temperate indigenous benthic organisms have been poorly investigated. To provide new insights, we performed an experimental study on the interaction between the introduced proliferative red alga Asparagopsis taxiformis and the indigenous Mediterranean coral Astroides calycularis. The biological response measurements included meta–barcoding of the associated microbial communities and metabolomic fingerprinting of both species. Significant changes were detected among both associated microbial communities, the interspecific differences decreasing with stronger host interaction. No short term effects of the macroalga on the coral health, neither on its polyp activity or its metabolism, were detected. In contrast, the contact interaction with the coral induced a change in the macroalgal metabolomic fingerprint with a significant increase of its bioactivity against the marine bacteria Aliivibrio fischeri. This induction was related to the expression of bioactive metabolites located on the macroalgal surface, a phenomenon which might represent an immediate defensive response of the macroalga or an allelopathic offense against coral.
