Parameters of the antioxidant system as well as carbohydrate, protein, and energy metabolisms in the tissues of an invader species, the bivalve mollusk Anadara kagoshimensis, are compared. Tissue specificity of the examined parameters is demonstrated. Along with the hepatopancreas and gills, the foot of anadara is shown to be an important metabolic organ with a high metabolism and an antioxidant defense. The content of low molecular weight biological antioxidants and antioxidant enzyme activities are specifically balanced in the examined mollusk tissues. The behavioral, physiological, and biochemical features that have provided successful invasion of this mollusk in the Black Sea-Azov basin are discussed.

“…When these become invasive they can rapidly spread and monopolize space, alter food webs, and modify both ecosystem structure and function (Thresher, 2000; Katsanevakis et al, 2014). Shipping has been reported as the most important pathway for the introduction of NIMS and in recent years more than a thousand marine alien species have been reported in European seas, even though efforts to monitor and report alien species vary among European countries (Katsanevakis et al, 2013). …”

BackgroundThe introduction of exotic species can have serious consequences for marine ecosystems. On the shores of the Cantabrian Sea (North of Spain) there are no routine examinations of seaweeds that combine molecular and morphological methods for early detection of exotic species making it difficult to assess in the early stages their establishment and expansion processes as a result of anthropogenic activities (e.g., shipping and/or aquaculture).MethodsIn this work we used both morphological identification and molecular barcoding (COI-5P and rbcL genes) of red algae collected in Asturias, Bay of Biscay (Gijón and Candás harbours) and from the University of Oviedo’s herbarium samples.ResultsThe results confirmed the presence of exotic Asian seaweeds Pachymeniopsis gargiuli and Grateloupia turuturu Yamada on Cantabrian Sea shores. Several individuals of these species were fertile and developing cystocarps when collected, underlining the risk of possible expansion or continued establishment. This study constitutes the first report of the Asian P. gargiuli in this area of the Bay of Biscay.ConclusionsHere the presence of the exotic species of the Halymeniales P. gargiuli is confirmed. We hypothesize that this species may have been established some time ago as a cryptic introduction with G. turuturu in Galician shores. The detection of these species on the shores of the Cantabrian Sea is relevant since introductions of Pachymeniopsis species could have been overlooked on other European coasts, probably mixed with G. turuturu and P. lanceolata. Our results confirm one new alien seaweed species that has been detected using molecular methods (COI-5P region and rbcL genes barcoding) on North Atlantic shores: the Asian native P. gargiuli. This demonstrates that routine screening for early detection of exotic algae in the Cantabrian Sea can be used for risk assessment. Genetic barcoding should be done using both rbcL gene and COI-5P regions since, although COI-databases are still poorer in sequences and this inhibits successful outcomes in Grateloupia-related species identifications, it is nonetheless a useful marker for species-level identifications in seaweeds.

“…This Lessepsian migration, a term coined in memory of the French engineer Ferdinand De-Lesseps (Por, 1971), does not show any sign of abating. More than 430 marine alien species have been recorded along the coasts of Israel (Katsanevakis et al, 2013). These newly established species can have an enormous impact on ecosystem functioning, especially through competition with native species, which can lead to physical habitat alterations and influence the food provision (Katsanevakis et al, 2014;Spanier & Galil, 1991;Ruiz et al, 1997;Galil, 2011).…”
