“…(García et al, 2018). Due to the wide physiological adaptations of C. fragile and its preference for higher temperatures during the reproductive season (Hanisak, 1979), new potential niches for its settlement are proliferating under current climatic conditions (Zanolla & Andreakis, 2016). Spatio-temporal information of native and invasive Codium spp.…”

“…eDNA has proved useful for the detection of aquatic invertebrates (Deiner, Fronhofer, Mächler, Walser, & Altermatt, 2016;Mächler, Deiner, Steinmann, & Altermatt, 2014) and vertebrates (Piaggio et al, 2014;Sigsgaard et al, 2016;Takahara et al, 2013), but the information on the aquatic plants and algae is still limited. Only a few studies have addressed the detectability of aquatic plants or algae with eDNA (Fujiwara, Matsuhashi, Doi, Yamamoto, & Minamoto, 2016;Keller, Hilderbrand, Shank, & Potapova, 2017;Scriver, Marinich, Wilson, & Freeland, 2015;Zimmermann, Glöckner, Jahn, Enke, & Gemeinholzer, 2015), due to the limited availability of reference databases (Cristescu, 2014) and the lineage-specific barcodes (Zanolla & Andreakis, 2016). To be useful for detecting seaweed, eDNA barcodes need to be specific (Verbruggen et al, 2010) and have a suitable resolution across multiple regions (Zanolla & Andreakis, 2016) within the suspected introduced range of targeted taxa (Geller, Darling, & Carlton, 2010).…”

Given the increase in invasion rates worldwide (Ruiz, Carlton, Grosholz, & Hines, 1997), the use of eDNA has the potential to revolutionize the detection of cryptic invasive seaweed, which has been rarely assessed until now.…”

Aim Codium fragile , an invasive seaweed, has spread widely during the last century, impacting on local seaweed communities through competition and disturbance. Early detection of C. fragile can help on its control and management. Environmental DNA (eDNA) has proved successful for early detection of aquatic invasive species but its potential use for seaweed remains understudied. We used a species‐specific eDNA qPCR approach to investigate the spatial distribution, abundance, and coexistence of the invasive C. fragile and three native Codium species ( Codium vermilara , Codium tomentosum , and Codium decorticatum ) in the Cantabrian Sea. Location Bay of Biscay, Northern Atlantic Coast of the Iberian Peninsula; two ports, a beach and a rocky cliff. Methods We designed species‐specific primers in barcoding regions targeting short fragments of the rbcL gene for the invasive Codium species, and the elongation factor Tu (tufA) gene for the native species, to assess their spatial and seasonal distributions using quantitative real‐time PCR in samples collected during summer, autumn, and winter. Results We found seasonal differences in the presence of the invasive Codium fragile and two of the native Codium species, but did not detect C. decorticatum at any point. Species distribution patterns produced with qPCR targeting species‐specific eDNA coincided with the known distribution based on previous conventional sampling, with a seasonal alternance of C. fragile and C. vermilara , and a marked dominance of invasive C. fragile in ports, which are known hotspots for invasive species. Main conclusions Our results demonstrate the utility of using eDNA for early detection and monitoring of invasive seaweed. Native and invasive Codium spp. displayed significant seasonal and spatial differentiation that needs to be taken into account in risk management. Regular monitoring of ports and adjacent areas using eDNA should help to assess the potential expansion of invasive Codium and the need for management interventions to avoid the displacement of native seaweed.

“…The combination of molecular phylogeographic inference, ecophysiological studies and species distribution modelling (SDM) represents a powerful tool for the detection of introduced species and the identification of their source populations (Booth et al. , Zanolla and Andreakis ) but also for predicting species and population expansion and assessing the impact and invasive potential of invaders at multiple stages in the invasion process (Peterson , Bolton et al. , Marcelino and Verbruggen ).…”

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

“…Native to the Indo‐Pacific region (Harvey ) and remarkably ubiquitous (see fig. B in Dijoux et al for worldwide distribution), A. taxiformis is actually a species complex composed of six cryptic lineages, with different geographical distributions (Andreakis et al , ; Dijoux et al ; Zanolla & Andreakis ). Broad physiological plasticity and high genetic variability (Zanolla et al ; Zanolla et al , unpubl.…”

SUMMARYIn this study, we present basic population data of the red macroalga Asparagopsis taxiformis, widely recognized as invasive in the Mediterranean Sea. A 13-month field study was carried out on a population located in southern Spain, addressing its phenology, population dynamics and demography. We further tested whether biomass variations were related to environmental variables at the study site. Gametophytes were present year-round while tetrasporophytes were only found in spring and summer. Recruitment capacity and vegetative growth of the gametophytes are discussed as important modulators for the population structure and enhancers of its persistence. Thallus size-time histograms revealed a high prevalence of small shoots that showed high mortality that was not related to self-thinning. Biomass of A. taxiformis was higher from March to July. Vegetative growth was the main way the gametophyte population was maintained, although the presence of tetrasporophytes and fertile gametophytes in the field confirms that sexual reproduction also occurs. Its continuous and high recruitment, in terms of the number of smallest shoots, makes this southern population of A. taxiformis a source of future invasive populations due to the intensive maritime traffic in the region.
