Abstract. The long held perception of the deep sea consisting of monotonous slopes and uniform oceanic basins has over the decades given way to the idea of a complex system with wide habitat heterogeneity. Under the prism of a highly diverse environment, a large dataset was used to describe and compare spatial patterns of the dominant small-size components of deep-sea benthos, metazoan meiofauna and bacteria, from Mediterranean basins and slopes. A grid of 73 stations sampled at five geographical areas along the central-eastern Mediterranean basin (central Mediterranean, northern Aegean Sea, Cretan Sea, Libyan Sea, eastern Levantine) spanning over 4 km in depth revealed a high diversity in terms of both metazoan meiofauna and microbial communities. The higher meiofaunal abundance and richness observed in the northern Aegean Sea highlights the effect of productivity on benthic patterns. Non parametric analyses detected no differences for meiobenthic standing stocks and major taxa diversity (α, β, γ and δ components) between the two habitats (basin vs. slope) for the whole investigated area and within each region, but revealed significant bathymetric trends: abundance and richness follow the well-known gradient of decreasing values with increasing depth, whereas differentiation diversity (β- and δ-diversity) increases with depth. In spite of a similar bathymetric trend observed for nematode genera richness, no clear pattern was detected with regard to habitat type; the observed number of nematode genera suggests higher diversity in slopes, whereas richness estimator Jack1 found no differences between habitats. On the other hand, δ-diversity was higher at the basin habitat, but no differences were found among depth ranges, though turnover values were high in all pairwise comparisons of the different depth categories. Results of multivariate analysis are in line with the above findings, indicating high within habitat variability of meiofaunal communities and a gradual change of meiofaunal structure towards the abyssal stations. In contrast to meiobenthic results, microbial richness is significantly higher at the basin ecosystem and tends to increase with depth, while community structure varies greatly among samples regardless of the type of habitat, depth or area. The results presented here suggest that differences in benthic parameters between the two habitats are neither strong nor consistent; it appears that within habitat variability is high and differences among depth ranges are more important.

Interesting Species

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.

Abstract The present study has been conducted to find out new findings on maximum length and weight values of Umbrina cirrosa in the Bay of Saros (Northern Aegean Sea, Turkey). On September, 11, 2016, a single specimen of Umbrina cirrosa with 68.8 cm total length and 2600.00 g total weight was caught by handline at a depth of 20 m. The provable size is the second largest length ever reported in the all seas of the world

A New Species

A new species of Lumbrineridae, Augeneria profundicola sp. nov. is described based on one specimen taken from 950 m depth on muddy bottom off Gökçeada Island (northern Aegean Sea). This new species is characterized by having seven small nuchal antennae arranged in a circle line on the prostomium and bidentate maxilla II. The morphological features of this species were compared with those of all Augeneria species described so far. A taxonomic key to all Augeneria species is also provided.

Abstract This study was carried out in April - June 2014 to determine absolute fecundity (F) of the chub mackerel (Scomber japonicus Houttuyn, 1782) in Saros Bay (Aegean Sea, Turkey). The relations between the absolute fecundity and total length, total weight and age of the chub mackerel females were estimated as F=0.0318TL4.81, F=1573.9TW- 42858 and F=109607A-136129, respectively. This study aims to contribute to the reproductive biology of S. japonicus by reporting the first findings about the absolute fecundity of the species for the Aegean Sea.
