Faunistical analysis of benthic samples collected from different depths and biotopes (0–195 m) at 108 stations along the Turkish Aegean coast yielded 11 species and 5 subspecies of Sipuncula. Two species (Phascolion (Isomya) tuberculosum and Aspidosiphon (Aspidosiphon) misakiensis) are new to the eastern Mediterranean fauna and 8 species are new to the Turkish fauna. Onchnesoma steenstrupii steenstrupii has the highest dominance and frequency index values in the study area. Aspidosiphon (Aspidosiphon) elegans and Apionsoma (Apionsoma) misakianum are alien species. Of the biotopes examined, muddy sand was characterized by the highest number of species and specimens, whereas sponges and coralligenous substrata were characterized by the lowest number of species and specimens. The biometrical and reproductive features of the species are presented and discussed.

This paper deals with the sipunculan species distributed in Izmir Bay (Aegean Sea, eastern Mediterranean). Benthic samples were taken at 29 stations between 1998 and 2001 at depths ranging from 8 to 77 m. Six species and 200 individuals belonging to three families were found. Aspidosiphon (A.) mexicanus is newly recorded from Izmir Bay. The majority of specimens were found on a sandy-mud substratum (42%), followed by sand (35%), muddy-sand (19%) and sand (3%), respectively. Among the habitats, Posidonia oceanica and muddy-sand were represented by the highest numbers of species (4 species), followed by sandy-mud (3 species), and sand (2 species). The densities of the species at sampling stations were determined and compared seasonally, based on the data collected in 2001. Brief descriptions of the species and their distributional, reproductive and ecological characteristics are given.

Two New Species

Three species belonging to the subgenus Minuspio are described from the southern coast of Turkey. Prionospio (Minuspio) anatolica sp. nov., and Prionospio (Minuspio) maciolekae sp. nov. are new to science and P. (M.) pulchra is a new report for the marine fauna of the Levantine and Black Sea coasts of Turkey. Prionospio (M.) anatolica sp. nov., differs from all other Prionospio (M.) species by the shape of the prostomium, branchiae, and the absence of eyes. This species has 7 pairs of long, apinnate branchiae on chaetigers 2 to 8. Prionospio (M.) maciolekae sp. nov., differs from other Prionospio (M.) species in having short, densely ciliated branchiae and distinct dorsal crests on chaetigers 10–28. The examination of older materials deposited at the Museum of Ege University (ESFM) revealed that Prionospio (M.) pulchra, an alien invasive species, also occurred in the Aegean and Black Seas since 2000. In the Mediterranean, this species seems to be first noticed from the Italian waters (Tyrrhenian Sea, Lago di Sabaudia) and misidentified as Prionospio cirrifera. These species were encountered on a variety of biotopes in the region. In addition, two specimens of P. (M.) multibranchiata collected near the type locality (Bazan Bay, Pacific coast of Canada) were examined and a redescription of this species was made. The morphology, ecology and distribution of these species are given together with a taxonomic key to all valid species of the subgenus Minuspio.

This study reports four alien polychaete species new to the marine fauna of Greece. These species are -Pseudopolydora paucibranchiata (family Spionidae),Paraprionospio coora (family Spionidae), Marphysa disjuncta (family Eunicidae), and Chaetozone corona(family Cirratulidae). Another species of Chaetozone, though not an alien one, Chaetozone gibber is reported here from Greek waters. All of them have been currently reported from the coasts of Turkey (Aegean or Levantine Seas). Pseudopolydorapaucibranchiata and Marphysa disjuncta, probably introduced to the region through ballast waters, seem to have been well established in the Mediterranean Sea. Chaetozone corona and Paraprionospio coorawere considered to be cryptogenic. Pseudolydora paucibranchiata was found in great densities in a very disturbed site, confirming the opportunistic character of this species. Chaetozone corona and Chaetozonegibber showed a wider distribution pattern, though their abundance increased in disturbed sites.Marphysa disjuncta was found in disturbed as well as in undisturbed sites along the coasts of Greece.Paraprionospio coora shows a distribution pattern indicating an opportunistic character. These new findings increase the number of polychaete species from the Hellenic Seas to 777 species.

Biological invasions are considered one of the main threats for biodiversity. In the last decades, more than 60 macroalgae have been introduced in the Mediterranean Sea, causing serious problems in coastal areas. Nevertheless, the impacts of alien macroalgae in deep subtidal systems have been poorly studied, especially in the coralligenous habitats of the eastern coast of Sicily (Italy). Therefore, within the framework of the programme “Progetto Operativo di Monitoraggio (P.O.M.)” of the EU Marine Strategy Framework Directive (MSFD), the aim of the present study was to gain knowledge on the alien macroalgae present in coralligenous habitats of the Marine Protected Area (MPA) Isole Ciclopi, along the Ionian coast of Sicily. By Remotely Operated Vehicle (ROV) videos and destructive samples analysed in the laboratory, five alien species were identified: Caulerpa cylindracea, Antithamnion amphigeneum, Asparagopsis armata, Bonnemaisonia hamifera, and Lophocladia lallemandii. Since A. amphigeneum was previously reported only in the western Mediterranean and Adriatic Sea, the present report represents the first record of this species in the eastern Mediterranean. The ROV surveys showed that the alien species do not have a high coverage and do not appear to be invasive in the coralligenous area of the MPA. Since ocean temperatures are predicted to increase as climate change continues and alien species are favoured by warming of the Mediterranean Sea, the risk of biotic homogenisation caused by the spread of alien species is realistic. Therefore, further studies are needed to assess the incidence and invasiveness of alien species in phytobenthic assemblages of coralligenous in the MPA.

Quality Status

The soft-bottom zoobenthic community structure of Izmir Bay was examined seasonally at eight stations (depth-range: 19–67 m) in 2009. A total of 427 species were found. Polychaeta had the highest number of species (50% of total species) and individuals (75%), whereas Echinodermata possessed the highest biomass (47%). The number of species varied from 3 to 79 (0.1 m−2), the density from 60 to 5360 ind.m−2, and the biomass from 1 to 530 g.m−2. The most numerically dominant species were the polychaetesAricidea claudiae, Streblospio gynobranchiata, Levinsenia demiriandSternaspis scutata. The distribution of zoobenthos was strongly related to spatial differences in total organic carbon, sediment texture and depth among different regions of the bay rather than temporal differences among seasons. However, significant seasonal variability in community structure (mainly differences in the relative abundance of species) was present. The inner region of the bay can be classified as ‘poor’ or ‘bad’ based on the results of biotic indices (H′, AMBI, m-AMBI and BENTIX). Among biotic indices, only H′ and m-AMBI appeared to be capable of explaining the bay's benthic quality status. Thirteen alien species were also found.Streblospio gynobranchiata, Prionospio pulchra, Pseudopolydora paucibranchiataandPolydora cornutaformed dense populations in the inner most polluted part of the bay and are considered to be new pollution indicator species in the eastern Mediterranean Sea.

Brittle stars were collected on the southern coast of Turkey in 2005 and 2009. The most abundant species found (up to 420 ind. m -2 ) was Amphiodia obtecta. The taxonomic status of this species was unclear and is revised here. This is the first record of the genus Amphiodia in the Mediterranean Sea; it probably originates from the Red Sea, since it is absent from the entire Atlantic Ocean. Among the other species found, Ophiactis macrolepidota (previously reported as O. parva in the Mediterranean) is a new record for the marine fauna of Turkey.

A New Species

The present study deals with species of the subgenera Prionospio (Aquilaspio) and Prionospio (Prionospio) collected from various habitats and depths along the southern coast of Turkey in September and October 2005. The examination of a large collection of material revealed 10 species, of which one species, Prionospio (P.) ergeni n. sp., is new to science; two species, P. (P.) depauperata and P. (A.) krusadensis, are new to the Mediterranean fauna; and one species, P. (A.) sexoculata, is new to the Turkish marine fauna. Prionospio (P.) ergeni n. sp. differs from all other Prionospio species in having three pairs of pinnate branchiae between chaetigers 2 and 4 and one pair of apinnate branchiae on chaetiger 5. Four species―P. (P.) saccifera, P. (A.) sexoculata, P. (P.) depauperata, and P. (A.) krusadensis―are aliens. The former two species could have been introduced to the Mediterranean from the Red Sea through the Suez Canal (Lessepsian migrants) and the others from the Pacific or Indian Oceans via ballast water of ships. The morphological, ecological, and distributional features of these species are discussed.
