MACROBENTHIC FAUNA ASSOCIATED WITH THE INVASIVE ALIEN SPECIES BRACHIDONTES PHARAONIS (MOLLUSCA: BIVALVIA) IN THE LEVANTINE SEA Melih Ertan Çinar1, Bilal Öztürk1, Kerem Bakir1, Tuncer Katağan1, Alper Doğan1, Şermin Açik Çinar2, Güley Kurt-Şahin3, Tahir Özcan4, Ertan Dağli1, Banu Bitlis Bakir2, Ferah Koçak2, Fevzi Kirkim1 1Ege University, Faculty of Fisheries, Department of Hydrobiology, Bornova, İzmir, Turkey 2Dokuz Eylül University, Institute of Marine Sciences and Technology, İnciraltı, İzmir, Turkey 3Sinop University, Faculty of Art and Sciences, Department of Biology, Sinop, Turkey 4Iskenderun Technical University, Faculty of Marine Sciences and Technology, Hatay, Turkey The invasive alien mytilid species, Brachidontes pharaonis, dominates the medio-littoral and upper-infrallitoral zones of the Levantine Sea. It forms a biogenic habitat in the area and host a number of alien and native species. Three-replicated samples of Brachidontes pharaonis were taken by a quadrate of 20x20 cm in dimension at 7 stations along the Levantine coast of Turkey in September 2005. Examinations of samples yielded 189 macro- benthic invertebrate species and 23407 specimens belonging to 13 taxonomic groups. Polychaeta accounted for up to 48% of the total number of species, whereas Mollusca comprised 46% of the total number of individuals. The dominant species in the habitat were Stenothoe dollfusi (12%), Spirobranchus kraussi (10%), Mytilaster minimus (7%) and Elasmopus pocillimanus (12%). The species with the highest frequency values were Pseudonereis anomala, Phascolosoma stephensoni and E. pocillimanus. The highest faunal density and the biomass (wet weight) in the habitat were estimated as 72550 ind.m2 and 19178 g.m2, respectively. The species number in samples changed between 14 and 47 species in the area. The mean diversity index values ranged from 1.72 to 2.27, and the mean evenness index values from 0.37 to 0.62. In the investigated area, two faunal assemblages were encountered, and the species responsible for the dissimilarity of the assemblages were E. pocillimanus, Syllis prolifera and Stenothoe dollfusi. The environmental variables best explaining variation in zoobenthic community structures were salinity, dissolved oxygen and nitrogen in the water column.

Based on literature records and original samples, we review here the knowledge of the Lebanese marine bivalve biota, tracing its changes during the last 170 yr. The updated checklist of bivalves of Lebanon yielded a total of 114 species (96 native and 18 alien taxa), accounting for ca. 26.5% of the known Mediterranean Bivalvia and thus representing a particularly poor fauna. Analysis of the 21 taxa historically described on Lebanese material only yielded 2 available names. Records of 24 species are new for the Lebanese fauna, and Lioberus ligneus is also a new record for the Mediterranean Sea. Comparisons between molluscan records by past (before 1950) and modern (after 1950) authors revealed temporal variations and qualitative modifications of the Lebanese bivalve fauna, mostly affected by the introduction of Erythraean species. The rate of recording of new alien species (evaluated in decades) revealed later first local arrivals (after 1900) than those observed for other eastern Mediterranean shores, while the peak in records in conjunc- tion with our samplings (1991 to 2010) emphasizes the need for increased field work to monitor their arrival and establishment.

La crevette à capuchon ressemble à un minuscule homard. Les femelles atteignent 20 mm, les mâles 26 mm. La couleur est brunâtre, rougeâtre (surtout les femelles) ou bleu-verdâtre (plutôt les mâles) avec une ligne blanche médiodorsale très fréquente. Toutefois, l’espèce présente des changements de coloration en fonction de la couleur du substrat, de l’éclairement et d'un rythme jour/nuit. Le rostre est droit, aigu, et sans dents. Les dents frontales (extra-orbitaires) de la carapace sont bien marquées et aiguës. Les yeux sont en partie recouverts par le bord antérieur de la carapace. Les pinces sont très fortes et légèrement inégales. Les pattes de la seconde paire possèdent 5 articles au carpe et sont terminées par une pince minuscule. La crevette à capuchon est sédentaire ; elle se nourrit de petits organismes benthiques (vers, larves, algues, foraminifères etc.). L’accouplement se fait en position « en croix ». Les femelles sont ovigères d'avril à septembre sur les côtes françaises et les larves sont dans le plancton de mai à décembre.

  • Effect of an Exotic Prey on the Feeding Pattern of a Predatory Snail

Wise Faculty of Life Sciences, Tel-Aviv University, Ramat-Aviv, Tel-Aviv 69978, Israel Received 11 November 2000; received in revised form 3 November 2001; accepted 15 December 2001 Abstract The mussel Brachidontes pharaonis, which invaded the Mediterranean fromthe Red Sea about 120 years ago, has recently become abundant in many midlittoral and some infralittoral rocky habitats along the Israeli rocky shore. We investigated the influence of B. pharaonis,as a novel prey, on the foraging patterns of the large whelk Stramonita haemastoma in the field, and examined food preferences in the laboratory. S. haemastoma has shifted fromindigenous species to feeding on the novel mussel when abundant. The whelk prefers to prey upon the invasive mussel over all indigenous species offered (e.g. barnacles and mussels), probably due to its larger size. In the midlittoral zone, the foraging activity of S. haemastoma is considerably low even where refuges are readily available (incisioned-rocks) and food density is high (mainly B. pharaonis). Higher proportions of whelks are actively foraging in the infralittoral zone but usually on smaller prey, mostly barnacles. We suggest that this differential foraging activity in the two zones is related to the degree of exposure to wave action. The midlittoral is inherently more exposed to wave action than the infralittoral, where sea conditions are more benign and the whelks may enjoy longer activity periods.

  • Aliens in the Mediterranean 5
    Invasions of alien species pose a serious threat to the unique Mediterranean biodiversity aliensin the Mediterranean Caulerpa racemosa is a fast growing macroalgae native to Western Australia. It was introduced in the Mediterranean by shipping and aquarium trade related activities and nowadays extensive populations are found along the Mediterranean coastline. It is known to attain total coverage in certain areas within six months of entry, out-competing other native macroalgae and causing drastic changes in the composition of the phytobenthos.
