Bursatella Leachii

One of the well- established alien species in the eastern Mediterranean basin is Bursatella leachii, also known as a lessepsian immigrant. The present paper provides a contribution to Bursatella leachii’sdistribution in the Bay of Izmir, Turkish Aegean Sea.

The present study reports on the occurrence of two specimens of the alien species Polydora cornutaBosc, 1802, in Elefsis Bay, the Saronikos Gulf (Aegean Sea, eastern Mediterranean). This is the firstrecord of this invasive alien species on the coast of Greece and the second report in the eastern MediterraneanSea after its first finding in Izmir Bay (on the Turkish Aegean coast). This finding enhances its distributionalpattern within the 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.

Passive Drift

Population dynamics in the marine realm can shape species’ spatial structure and genetic variability between given geographical areas. Connectivity is an important factor of species’ population structure. In this study, we examined the genetic diversity and structure of white seabream (Diplodus sargus, L. 1758) in the eastern Mediterranean basin, using a panel of four microsatellite markers. Recorded low FST values within the study area indicate little evidence of genetic differentiation among populations. Results suggest high gene flow which may imply near-panmixia between populations, indicating the possibility of a probable movement of adult migrants, or strong passive drift at sea in early life stages of the species. To this extent, bibliographically speaking, different species within the Sparidae family favor altered population dynamics patterns with respect to local populations and genetic divergence, in the context of the molecular marker used.

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.

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.

The alien muricid gastropod Ergalatax junionae Houart, 2008 has been known to inhabit the shallow waters of the eastern Mediterranean. The chronology of its recorded observations, beginning in eastern Turkey and proceeding to the south and west, suggests that it was first introduced to eastern Turkey via shipping, and was then spread in the Levantine Sea. The recent record from Greece indicates that its range of distribution is still expanding. Here we report local population densities and additional records of E. junionae from the eastern Mediterranean basin, including its first occurrence from the Turkish coastof the Aegean Sea.
