The Sfax southern coast (Gulf of Gabes, Mediterranean Sea) has been under increased anthropogenic pressure for many years. In the present study we investigated the effects of this anthropisation on the spatial distribution of copepod assemblages in relation to the physicochemical features of seawater at 20 stations sampled on 19 March 2013. Copepods represented 73% of total zooplankton abundance. Small planktonic copepods (<1.45mm), including pollution-tolerant species (e.g. Oithona nana, Paracalanus parvus, Harpacticus littoralis and Tisbe battagliai), proliferated exclusively in stations of ~0.5-m depth characterised by high coastal anthropogenic inputs. The largest copepod species were dominated by Calanus helgolandicus (1.45–2.5mm) in the offshore zone in depths of ~3m. Substantial numbers of Oithona plumifera (7.5%) were found at depths between 0.5 and 3m. Copepod diversity was significantly higher in the southern zone, which is less affected by sewage, than in the northern zone, which was subjected to higher pressure (Shannon–Wiener index H′=1.5–2.5 and ≤1.5 bits individual–1). A shift in the planktonic copepod community between the two zones was linked to deterioration of water quality, with higher phosphorus levels, turbidity and chemical oxygen demand (COD) in the northern zone.

“…The shallow hard bottom and intertidal soft-bottom of the Polychaetes assemblages along the coast of Alexandria,, in the south-eastern side of the Mediterranean Sea (Levantine Sea), were examined to detect the annual cycle of Polychaetes assemblages and analyze the spatial-temporal patterns of variation in assemblages and the relevant factors related to Polychaetes distribution (Dorgham et al, 2014;Zakaria et al, 2016Zakaria et al, , 2018.…”

“…However, D. rigida and D. oculata differ from D. minuta in having different spinulose spines originating in the mandible and the forehead being truncated broadly in the dorsal view (Bradford-Grieve et al, 1999). D. oculata is also closely related to D. rigida, which inhabits the Egyptian coast of the Mediterranean (Zakaria et al, 2016), but it can easily be recognized by its large eye lenses (Björnberg, 1963) and differing morphological characters. D. oculata has large terminal spines of swimming legs, whereas in D. rigida, the terminal spines of the exopod are shorter than the last segments of the swimming legs.…”

Introduction The eastern Mediterranean is sensitive to alien invasions due to its geographic position (i.e., its connection with Atlantic Ocean, Black Sea, and Erythrean regions), crowded maritime traffic, fisheries, and tourism activities in the coastal regions (Galil and Zenotos, 2002). Alien species increased after the opening of the Suez Canal in 1869 and construction of the Aswan Dam (Galil, 2000); hundreds of alien species passed through the Suez Canal to the Mediterranean Sea, forming thriving populations along the Levantine coast (Galil and Zenetos, 2002). To our knowledge, an average of 821 alien species have been reported in the Mediterranean Sea, of which approximately 75% were established in these ecosystems (Zenetos et al., 2017). The species belonging to Oithonidae are widely distributed in different ecosystems and are the most successful free-living cyclopoids in the marine ecosystems (Uye and Sano, 1998). This family is one of the most abundant taxa in estuarine, coastal, and oceanic regions (Paffenhöfer, 1993; Gallienne and Robins, 2001). The importance of the small copepods, such as Oithona, has been recently recognized in pelagic ecosystems (Gallienne and Robins, 2001). Moreover, Oithonidae species are important contributors to ecosystems of the
