“…Its first Mediterranean record is from Yumurtalik, Turkey in 1999 ( Albayrak & Çeviker, 2001 ), then from Kuşadesi, Turkey (Aegean Sea) in 2000. Then a decade later, it was reported from Cyprus and the Greek Dodecanese island of Astypalaia ( Zenetos, Konstantinou & Konstantinou, 2009 ; Zenetos et al, 2011 ), the Levantine coast of Turkey ( Bakir et al, 2012 ), Saronikos Bay, Western Aegean ( Zenetos et al, 2013 ), the Gulf of Thermaikos ( Manousis & Galinou-Mitsoudi, 2014 ), and Lesbos Island, mid-Aegean Sea ( Evagelopoulos et al, 2015 ).…”

The Mediterranean Sea is home to over 2/3 of the world’s charter boat traffic and hosts an estimated 1.5 million recreational boats. Studies elsewhere have demonstrated marinas as important hubs for the stepping-stone transfer of non-indigenous species (NIS), but these unique anthropogenic, and typically artificial habitats have largely gone overlooked in the Mediterranean as sources of NIS hot-spots. From April 2015 to November 2016, 34 marinas were sampled across the following Mediterranean countries: Spain, France, Italy, Malta, Greece, Turkey and Cyprus to investigate the NIS presence and richness in the specialized hard substrate material of these marina habitats. All macroinvertebrate taxa were collected and identified. Additionally, fouling samples were collected from approximately 600 boat-hulls from 25 of these marinas to determine if boats host diverse NIS not present in the marina. Here, we present data revealing that Mediterranean marinas indeed act as major hubs for the transfer of marine NIS, and we also provide evidence that recreational boats act as effective vectors of spread. From this wide-ranging geographical study, we report here numerous new NIS records at the basin, subregional, country and locality level. At the basin level, we report three NIS new to the Mediterranean Sea (Achelia sawayai sensu lato, Aorides longimerus, Cymodoce aff. fuscina), and the re-appearance of two NIS previously known but currently considered extinct in the Mediterranean (Bemlos leptocheirus, Saccostrea glomerata). We also compellingly update the distributions of many NIS in the Mediterranean Sea showing some recent spreading; we provide details for 11 new subregional records for NIS (Watersipora arcuata, Hydroides brachyacantha sensu lato and Saccostrea glomerata now present in the Western Mediterranean; Symplegma brakenhielmi, Stenothoe georgiana, Spirobranchus tertaceros sensu lato, Dendostrea folium sensu lato and Parasmittina egyptiaca now present in the Central Mediterranean, and W. arcuata, Bemlos leptocheirus and Dyspanopeus sayi in the Eastern Mediterranean). We also report 51 new NIS country records from recreational marinas: 12 for Malta, 10 for Cyprus, nine for Greece, six for Spain and France, five for Turkey and three for Italy, representing 32 species. Finally, we report 20 new NIS records (representing 17 species) found on recreational boat-hulls (mobile habitats), not yet found in the same marina, or in most cases, even the country. For each new NIS record, their native origin and global and Mediterranean distributions are provided, along with details of the new record. Additionally, taxonomic characters used for identification and photos of the specimens are also provided. These new NIS records should now be added to the relevant NIS databases compiled by several entities. Records of uncertain identity are also discussed, to assess the probability of valid non-indigenous status.

“…Along the Turkish coast, S. cumingii, which is an alien species in the Mediterranean, was previously reported as Septifer bilocularis (Linnaeus, 1758) from the Levantine coast of Turkey (İskenderun Bay) at a depth of 40 m (Albayrak and Çeviker, 2001). Zenetos et al (2003) later accepted S. bilocularis as a suspicious synonym of S. cumingii, which was later commented on by Albayrak and Çağlar (2006).…”

The last authors stated that the specimen of S. bilocularis given by Albayrak and Çeviker (2001) belongs to S. forskali Dunker, 1855 (one of the synonyms of S. cumingii). The species is also known from the Greek coast of the Aegean Sea (Zenetos et al, 2011).…”

The samplings were taken from various habitats such as mud, sand, rocks, Jania rubens, and Posidonia oceanica at different depths in the years 2000 and 2005; in total, 24 benthic samples were taken at 11 stations (Figure 1). The benthic material at shallow depths (0-5 m) was sampled by using a quadrat frame (20 cm × 20 cm) and randomly by snorkeling, whereas a van Veen grab (0.1 m 2 ) and dredge were used at deeper stations (5-180 m). Three replicates were taken at each grab and quadrat station. Some of the ecological features of the sampling stations are given in Table 1.In the field, the sampled material was sieved through a 0.5-mm mesh, and retained material was placed in jars containing a 4% seawater-formalin solution. In the laboratory, the material was sorted according to taxonomic groups under a stereomicroscope and preserved in 70% ethanol. After the molluscs were identified and counted, Soyer's frequency index was calculated for each benthic sample. The systematic classification follows the CLEMAM database (http://www.somali.asso.fr/clemam/index.clemam. html).The determined species have been stored at the Museum of the

The seagrass Posidonia oceanica forms extensive meadows in the Mediterranean Sea. Studies on their associated highly diverse invertebrate assemblages are limited to the western Mediterranean. The eastern Mediterranean, however, is a basin undergoing rapid change due to the synergistic effects of climate warming, biological invasions and other human stressors that are driving native biodiversity to regional-scale collapses. We here surveyed the shelled molluscan assemblage of a Posidonia oceanica meadow in Plakias, south-western Crete, the first such study in the eastern Mediterranean Sea. This area has increased its yearly mean temperature by 1 °C in the last 20 years and is under heavy pressure by Lessepsian species. We sampled across a 5- to 20-m depth gradient, in two seasons to capture intra-annual variation and the leaf and rhizome strata separately. Against our expectations, the molluscan assemblage proved to be highly diverse, with species richness, dominant species and trophic guilds comparable to healthy western Mediterranean ones, and with a negligible non-indigenous component. The diversity of the native community (following the biotic resistance hypothesis) and oxygen supersaturation in the meadow may cause greater resistance to biological invasions and warming, respectively, suggesting that Posidonia oceanica meadows may act as a precious refugium for native biodiversity in the fast changing eastern Mediterranean Sea.
