Loliginid squids of the Sepioteuthis lessoniana complex are widely spread in the Indo-Pacific Ocean, where they constitute a commercially important resource for neritic fisheries. Sepioteuthis lessoniana is the only Lessepsian squid migrant till now, recorded for the first time in the Mediterranean in 2002 along the Turkish Levantine coasts. Two maturing males, with mantle lengths 193 mm and 244 mm, have been recently caught near the coasts of Rhodes Island (SE Aegean), extending the species distribution northward, into Hellenic waters. Their identity was confirmed by comparison of the main body, beak characteristics and morphometric measurements with those available in the literature for this species. Suspected expansion of the Lessepsian loliginid into the Aegean Sea, due to the gradual warming of the sea, is discussed.

The organismic assemblage associated with Caretta caretta was studied in 37 loggerhead turtles, washed ashore dead at various localities in the northern Aegean Sea. A total number of 63 macrobenthic species and 17 species of macroalgae were identified. From these species, 41 and 13 respectively are reported for the first time as epibionts of this turtle. Analysis of the epibiont species distribution on six loggerhead turtles gave some evidence regarding the settlement preferences of certain epibiont species. From a biogeographical point of view, 61·3% of the epibiont species were cosmopolitan, 30·7% had an Atlanto-Mediterranean distribution, while 8% were Mediterranean endemics.

The present study provides additional data on the distributional range of six alien foraminiferal species in living assemblages from Greek coastal areas (Aegean Sea, Eastern Mediterranean). Amphistegina lobiferaLARSEN 1976, Sorites orbiculus (FORSK L 1775) and Coscinospira hemprichii EHRENBERG 1839 are well established in Greek coastal areas, whereas Triloculina fichteliana D'ORBIGNY 1839, Planogypsina acervalis (BRADY 1884) and Cymbaloporetta plana (CUSHMAN 1924), are recorded for the first time in this paper. The occurrence of these species in a number of sites in the Aegean Sea establishes their presence in the Eastern Mediterranean.

Four sponge species (Sycon raphanus, Sycon ciliatum, Paraleucilla magna and Dysidea fragilis) were found on artificial hard substrata of several ports in the inner and middle parts of Izmir Bay. The invasive alien species Paraleucilla magna, is being recorded for the first time from the Aegean coast of Turkey. It was very abundant almost at all studied ports, covering up to 35% of the sampled surfaces. The morphological and distributional features of the four species are described.

The presence of the crab Actaeodes tomentosus, native to the Indo-Pacific Ocean and the Red Sea, is documented for the first time in the Mediterranean Sea, on the basis of two specimens collected from Rhodes Island (Aegean Sea), a marine area particularly vulnerable to warm-water alien invasions. Along with the recent report of Xanthias lamarckii in similar conditions and region, the finding of another non-indigenous xanthid opens many questions regarding their occurrence in the area. Apart from the Lessepsian migration, other possible vectors of introduction are therefore examined.

Sampling studies in the Turkish Aegean Sea revealed the occurrence of the sea spider species, Trygaeus communis Dohrn, 1881. The genus Trygaeus and species Trygaeus communis Dohrn, 1881 are recorded for the first time from Turkey. The genus and species are also recorded for the second time from the Eastern Mediterranean Sea. Distribution map of the species in the Eastern Mediterranean Sea is provided, together with photographs and line drawing of the species. This record further extends the known distribution of the species to Turkey in the Eastern Mediterranean.

A New Species

A systematic survey of the sponge fauna of the Aegean Sea has been carried out. Twenty-eight stations located in the Aegean Sea were explored and 59 species of Demospongiae were collected from this particular area, which covers a broader geographical area of the Aegean and Cretan Seas. Some of the species found are poorly known for the Mediterranean fauna, like Cerbaris curvispiculifera and Spongosorites flavens, which are reported for the first time in the Aegean Sea and generally in the eastern Mediterranean. The species Axinyssa michaelis sp. nov. (Halichondriidae: Halichondrida) is new to science. In this paper, a description of the new species is presented along with the description of the first recorded species in the Aegean Sea. In addition to the taxonomic description of the species, some ecological data and a distribution pattern are also presented.

AbstractDuring benthic surveys in the northern Aegean Sea, 188 amphipod species were found; 39 among these comprise new records for the amphipod fauna of the eastern Mediterranean Sea, 41 are reported for the first time from the Aegean Sea and 62 are new for the fauna of the northern Aegean Sea. A checklist of the amphipods known from the Aegean Sea up to the present is given (239 species), along with their distribution in certain Mediterranean areas. For the most interesting species found, information on their distribution and their habitat is given. The amphipod fauna of the above areas is estimated, on the basis of the relevant literature. Finally, the affinities among these areas using the coefficient of Czekanowski, along with the number of species common to each pair of areas, are estimated.

Archaeological excavations in two coastal sites of Greece, Ftelia on Mykonos and Cyclops Cave on Youra, have provided suitable material (charcoal/marine mollusk shell paired samples deposited simultaneously in undisturbed anthropogenic layers) to estimate regional changes of the sea surface radiocarbon reservoir effect (ΔR) in the Aegean Sea. Moreover, pre-bomb 14C ages of marine mollusk shells of known collection date, from Piraeus and Nafplion in Greece and Smyrna in Turkey, also contributed to the marine reservoir calculation during recent years. In this article, these already published results, 10 in total, are considered and calibrated again using the latest issues of the calibration curves IntCal13 and Marine13. The same calibration data were applied to 11 more paired samples from the archaeological sites of Palamari on Skyros and Franchthi Cave in the Argolic Gulf, published here for the first time, in order to investigate the fluctuation of the reservoir ages R(t) and ΔR values in the Aegean Sea from ∼11,200 BP (∼13,000 cal BP) to present. Our data show that R(t) and ΔR values are not constant through time and may vary from 1220 ± 148 to −3 ± 53 yr and −451 ± 68 to 858 ± 154 14C yr, respectively. An attempt was also made to correlate these fluctuations with eastern Mediterranean paleo-environmental proxies and other relevant paleoceanographic data found in the literature.

Microplastics (MPs) are becoming ubiquitous in the marine environment and shallow marine sediments are one of the major sinks for MPs. In order to improve the knowledge about the environmental fate of MPs in the Aegean Sea shallow sediments, the occurrence and spatial distribution of MPs in Samos Island (Greece) was investigated for the first time, along a land-sea transect. The highest concentration of MPs was recorded at the Beach (37.2 ± 6.9 MPs/Kg DW), while the lowest concentration was recorded in the Intertidal zone (1.1 ± 0.9 MPs/Kg DW). In relation to the different shapes, Fragments and Pellets were more abundant on the Beach, while Fibers were more abundant in the Intertidal zone and barely any Sheets were found along the transect, suggesting a distribution probably governed not only by size but also morphology and perhaps chemical composition. A higher accumulation of particles was recorded in the first 10 cm of sediments, in comparison to the deepest 5 cm, indicating an increase of microplastics in the shallow marine sediments.

The finding of a rare crab, Paragalene longicrura, is herein recorded from Thermaikos Gulf. This constitutes the northmost record of the species in Greek waters. The species is only known from sporadic records in the eastern Mediterranean basin. Ecological remarks on the habitat of P. longicrura and other decapod species are described for the first time for the Mediterranean.
