“…As supported by past records of the Atlantic tripletail, Lobotes surinamensis , in the Mediterranean dating back to 1875 with a specimen caught off the northern Sicilian coasts (Doderlein, ), the Mediterranean must be considered as part of the native range of L. surinamensis (Golani, Orsi Relini, Massutí, & Quignard, ; Psomadakis et al., ; Tortonese, ). The definition of ‘alien species’ refers to species occurring outside their historically known boundaries; in view of the numerous records in the Mediterranean, this basin must be considered as part of the distribution range of the Atlantic tripletail, although located at the margins of this range (Hemida, Golani, Diatta, & Capapé, ).…”

“…Although L. surinamensis is not entirely unknown in the northwestern waters of Mediterranean, it is a rare occurrence in other areas, as suggested by the few encounters of this species in the NW Mediterranean (De Pirro, Tosi, & Vanni, 1997;Palom, 1991;Psomadakis, Giustino, & Vacchi, 2012) In this context, the present paper reports a new record of Atlantic tripletail, Lobotes surinamensis (Bloch, 1790), from the Ligurian Sea, which represents the northernmost finding of this species in the NW Mediterranean.…”

Aim Typically, non‐indigenous species have been studied in relation to either the invaded (recipient) community or the donor community. However, we still lack a broad understanding of the mechanisms underlying the establishment of non‐indigenous species that combines both perspectives. Since the opening of the Suez Canal, hundreds of species have invaded the Mediterranean from the Red Sea, forming a unique system in which the entire species pool (donor, non‐indigenous and recipient) is known. Focusing on species ecological traits, we assess the drivers underlying the establishment of non‐indigenous species from the onset of the invasion to the present. Location The Mediterranean and Red Seas. Methods We compiled traits for shallow‐water hard‐bottom‐associated fishes in the Mediterranean (recipient community) and the Red Sea (donor community). We compared the multivariate community trait structure of non‐indigenous species with the donor and recipient assemblages, using a novel method to objectively assign trait‐weights, thereby increasing the robustness of the results. Patterns were contrasted with two types of null models which provide distinct insights into the ecological processes. Results Non‐indigenous fishes are very diverse ecologically, substantially increasing the total community trait diversity of the Mediterranean. Trait similarity between non‐indigenous and indigenous Mediterranean species was lower than expected, indicating that non‐indigenous fishes tend to occupy relatively vacant niches within the Mediterranean. However, we further found that over time non‐indigenous species display increased trait similarity to indigenous Mediterranean species. This suggests that trait constraints associated with successful establishment are weakening. Main conclusions Non‐indigenous species establish in relatively vacant ecological niches, opening the possibility for predicting establishment using ecological traits. However, the weakening of trait constraints through time suggests that forecasting future establishment may be difficult. Faced with an accelerating pace of invasion, it appears that the Mediterranean is going to be transformed into an extension of the Red Sea in terms of trait and species composition.

“…The presence of six species ( Carcharhinus melanopterus , Dipturus batis complex, Torpedo alexandrinsis , Leucoraja fullonica , Raja africana ), however, has not been confirmed [50,58–61]. In contrast, the presence of Dipturus nidarosiensis in the Mediterranean, a species formerly reported only from the North-Eastern Atlantic, has been ascertained by recent studies [58,62].…”

Improving the Conservation of Mediterranean Chondrichthyans: The ELASMOMED DNA Barcode Reference Library

et al. 2017

Cartilaginous fish are particularly vulnerable to anthropogenic stressors and environmental change because of their K-selected reproductive strategy. Accurate data from scientific surveys and landings are essential to assess conservation status and to develop robust protection and management plans. Currently available data are often incomplete or incorrect as a result of inaccurate species identifications, due to a high level of morphological stasis, especially among closely related taxa. Moreover, several diagnostic characters clearly visible in adult specimens are less evident in juveniles. Here we present results generated by the ELASMOMED Consortium, a regional network aiming to sample and DNA-barcode the Mediterranean Chondrichthyans with the ultimate goal to provide a comprehensive DNA barcode reference library. This library will support and improve the molecular taxonomy of this group and the effectiveness of management and conservation measures. We successfully barcoded 882 individuals belonging to 42 species (17 sharks, 24 batoids and one chimaera), including four endemic and several threatened ones. Morphological misidentifications were found across most orders, further confirming the need for a comprehensive DNA barcoding library as a valuable tool for the reliable identification of specimens in support of taxonomist who are reviewing current identification keys. Despite low intraspecific variation among their barcode sequences and reduced samples size, five species showed preliminary evidence of phylogeographic structure. Overall, the ELASMOMED initiative further emphasizes the key role accurate DNA barcoding libraries play in establishing reliable diagnostic species specific features in otherwise taxonomically problematic groups for biodiversity management and conservation actions.
