“…Comparing our results with those of Marchini et al (2015), we have found the same species association. The presence of these non-indigenous species as associated fauna in A. verticillata underlines the role that the spread of this latter species can play in the introduction of other alien species through transport on vessel hulls, which is considered the main way of introduction for A. verticillata.…”

New Mediterranean Biodiversity Records (July 2016)

et al. 2016

View full text Add to dashboard Cite

This contribution forms part of a series of collective articles published regularly in Mediterranean Marine Science that report on new biodiversity records from the Mediterranean basin. The current article presents 51 geographically distinct records for 21 taxa belonging to 6 Phyla, extending from the western Mediterranean to the Levantine. The new records, per country, are as follows: Spain: the cryptogenic calcareous sponge Paraleucilla magna is reported from a new location in the Alicante region. Algeria: the rare Atlanto-Mediterranean bivalve Cardium indicum is reported from Annaba. Tunisia: new distribution records for the Indo-Pacific lionfish Pterois miles from Zembra Island and Cape Bon. Italy: the ark clam Anadara transversa is reported from mussel cultures in the Gulf of Naples, while the amphipod Caprella scaura and the isopods Paracerceis sculpta and Paranthura japonica are reported as associated to the -also allochthonous-bryozoan Amathia verticillata in the Adriatic Sea; in the latter region, the cosmopolitan Atlantic tripletail Lobotes surinamensis is also reported, a rare finding for the Mediterranean. Slovenia: a new record of the non-indigenous nudibranch Polycera hedgpethi in the Adriatic. Greece: several new reports of the introduced scleractinian Oculina patagonica, the fangtooth moray Enchelycore anatina, the blunthead puffer Sphoeroides pachygaster (all Atlantic), and the lionfish Pterois miles (Indo-Pacific) suggest their ongoing establishment in the Aegean Sea; the deepest bathymetric record of the invasive alga Caulerpa cylindracea in the Mediterranean Sea is also registered in the Kyklades, at depths exceeding 70 m. Turkey: new distribution records for two non-indigenous crustaceans, the blue crab Callinectes sapidus (Atlantic origin) and the moon crab Matuta victor (Indo-Pacific origin) from the Bay of Izmir and Antalya, respectively; in the latter region, the Red Sea goatfish Parupeneus forsskali, is also reported. Lebanon: an array of records of 5 alien and one native Mediterranean species is reported by citizen-scientists; the Pacific jellyfish Phyllorhiza punctata and the Indo-Pacific teleosteans Tylerius spinosissimus, Ostracion cubicus, and Lutjanus argentimaculatus are reported from the Lebanese coast, the latter notably being the second record for the species in the Mediterranean Sea since 1977; the native sand snake-eel Ophisurus serpens, rare in the eastern Mediterranean, is reported for the first time from Lebanon, this being its easternmost distribution range; finally, a substantial number of sightings of the lionfish Pterois miles further confirm the current establishment of this lessepsian species in the Levantine.

“…This nonindigenous species may facilitate the transport of other alien species, as demonstrated by this study and others. In particular, the recent case study of Marchini et al (2015), in France, reported the same associated peracarid fauna.…”

“…This worldwide distribution of A. verticillata is a consequence of its fouling behavior in many places around the world. 23,24 Defensive chemistry against consumers and competitors has been proposed as an effective strategy for exotic species to colonize new areas in the marine environment, 22 but was not observed in the present investigation.…”

“…22 It has been proposed that defensive chemicals can be used to predict the potential invasiveness of introduced species. 22 The origin of A. verticillata is not known, but it is considered as an invasive species in many places around the world, 23,24 such as in Australia and New Zealand, 25 Brazil, 26 Portugal, 27 Upon collection, samples were placed in containers with seawater and transported to the laboratory immediately. The excess of water was eliminated using a salad spinner.…”

The present investigation tests the effects against feeding by fishes of crude extracts obtained from eleven distinct populations of the bryozoan Amathia verticillata, an invasive species found globally in tropical to warm-temperate waters. Investigation of extracts from 11 populations of A. verticillata led to the identification and quantification of the known indole alkaloid 2,5,6-tribromo-N-methylgramine and isolation and identification of the new indole alkaloid, 2,6-dibromo-N-methylgramine. One extract of A. verticillata from Brazil significantly deterred feeding, while other extracts of A. verticillata from Florida significantly stimulated feeding by fishes, in field assays performed in Brazil. The same extracts of Florida samples showed variable effects on feeding, ranging from attraction to deterrence, in assays carried out in Florida. The absence of broad chemical defenses against feeding by fish suggests that the establishment of A. verticillata as an invasive species into new areas may be due to reasons other than defensive chemistry.

“…Floating docks and other artificial substrates are very common in bays and estuaries, particularly in shipping areas and marinas are highly relevant for detecting new NIS arrivals [6][7][8]. The occurrence of artificial pontoons around the world may favour the dispersal of NIS, by providing stepping stones that allow colonization into new areas [9,10]. In fact, marinas and harbours have become an ideal study system for rapid assessment surveys (RAS) of NIS [e.g.…”
