“…Some inventories for polychaetes cover the entire Mediterranean Sea (Arvanitidis et al, 2002;Castelli et al, 2008;Coll et al, 2010), while others are limited to certain areas: Moroccan waters (both the Atlantic and Mediterranean coasts) (Gillet, 2017), the Mediterranean coast of France (Laubier & Paris, 1962;Dauvin et al, 2006), Italian waters (Castelli et al, 1995(Castelli et al, , 2008, the Adriatic Sea (Musco, 2012;Mikac, 2015), the Tunisian coasts (Ayari et al, 2009;Zaâbi et al, 2012, Mosbahi et al, 2017, the Aegean Sea (Ergen, 1976;Simboura & Nicolaidou, 1994, 2001Arvanitidis, 2000;Ergen et al, 2002Ergen et al, , 2006Faulwetter et al, 2017), the Levantine Sea (Laubier, 1966;Ben-Eliahu, 1995;Çinar, 2005, 2007Mutlu et al, 2010;Faulwetter et al, 2017;Dorgham et al, 2013Dorgham et al, , 2014, the Turkish coastline (Çinar et al, 2014) and the Black Sea (Arvaniditis et al, 2002;Şahin & Çinar, 2012).

The data analyzed to inventory of all polychaetes in Algerian waters make it possible to estimate the diversity of this group to 534 species. The most diversified families are Syllidae (66 species), Spionidae (37 species) and Terebellidae (27 species).The presence of these listed species along the Algerian coast is compared with their occurrence in nine other areas of the Mediterranean Sea, in the Black Sea and in four other areas of the World Ocean. Comparison are also made with respect to the indications of the biogeographical origin for each species. The polychaete fauna of the Algerian coast is among the richest of the Mediterranean Sea and comparable to that reported for the French Mediterranean continental shelf and the Aegean Sea, but higher that that found in the bordering coastlines of Morocco and Tunisia. Most of the species have an Atlantic origin and are present in the western Mediterranean Sea; this inventory includes eight Non-Indigenous Polychaete Species in the Algerian waters.

“…The granulometric analyses revealed that there were four groups of sediment types in the intertidal zone of the Kneiss Islands (previously described in Mosbahi et al, 2017). Zostera noltei eelgrass beds colonized all the sampled stations.…”

“…Sampling consisted of collecting the topmost 20 cm of the sediment, being carried out at 32 stations in April 2014, in areas corresponding to fully extended Z. noltei seagrass beds (Figure 1). The sediment analyses (proportions of mud, fine sand, medium sand and coarse sand) and organic matter contents measured in the sediment are the same as those reported in a previous paper on polychaete structure and seasonal patterns (Mosbahi, Dauvin, & Neifar, 2017).…”

Do intertidal Zostera noltei meadows represent a favourable habitat for amphipods? The case of the Kneiss Islands (Gulf of Gabès: Central Mediterranean Sea)

et al. 2020

The structure, diversity, spatial and seasonal distributions of amphipod assemblages associated with intertidal Zostera (Zosterella) noltei meadows were studied around the Kneiss Islands (central Mediterranean Sea). This site represents a site of international interest in terms of its ornithological diversity (Important Bird Area, Ramsar Site and SPAMI). The amphipod fauna was sampled at 32 stations in spring 2014. A total of 6,482 individuals belonging to 78 species and 22 families were identified; among these taxa, Lysianassa ceratina is new for the Tunisian amphipod inventory, whereas 25 species are identified for the first time in the Gulf of Gabès. The dominant species are Cymadusa filosa, Microdeutopus gryllotalpa, Gammarus insensibilis, Dexamine spiniventris, Monocorophium insidiosum, Elasmopus rapax, Melita palmata and Leucothoe incisa. Four amphipod assemblages are identified using MDS analysis. The distribution of amphipod assemblages is linked to several environmental factors, such as sediment type, organic matter content and distance from the shore, which is itself associated with a clear inshore–offshore gradient. Seasonal variations of the amphipod assemblage patterns at eight stations, sampled between April 2014 and January 2015, show a maximum abundance and diversity during summer and autumn, with a minimum in winter. These seasonal fluctuations may be related to many factors such as variations of climatic factors (e.g. temperature, salinity), the growth and production rates of Zostera noltei meadows and seasonal patterns in the life cycle of dominant species.

“…However, there are few quantitative studies designed to examine soft-bottom communities and the impacts of NIS in soft sediment habitats (Travizi et al 2019). In Tunisia, the majority of benthic macrofauna studies have focused on macrobenthic communities of shallow coastal areas (i.e Khedhri et al 2014;Fersi et al 2018;Boudaya et al 2019;Mosbahi et al 2017Mosbahi et al , 2019Mosbahi et al and 2020.…”

This study from January to December 2018 was the rst initiative of a Port Baseline Survey (PBS) aimed at assessing the impact of biological invasions in harbours of the Gulf of Gabès (GG). A total of 12 shing and industrial harbours were seasonally prospected during 2018. A total of 174 macrobenthos taxa were recorded, belonging to eight zoological groups, with a dominance of crustaceans (32%), molluscs (31%) and polychaetes (20%). Among these taxa, 57 were Non-Indigenous Species (NIS) for Tunisian waters, while 27 species were recorded for the rst time in GG harbours and three decapods ( Dyspanopeus sayi, Hippolyte prideauxiana and Pilumnus minutus ) and one amphipod ( Hamimaera hamigera ) were newly recorded from Tunisian waters. Two main categories of harbours are distinguished according to their macrobenthic communities and environmental features (essentially edaphic factors). The industrial harbours yield higher numbers of species and abundance of NIS than the shing ports. The ALEX metric is used to evaluate the biological invasion status of the Gulf of Gabès harbours, showing that their status ranges from unaffected in shing harbours to extremely affected in industrial harbours. Three biotic indices (AMBI, BO2A and BENTIX) are applied to assess the ecological status of harbours, which varies from moderate to good. ALEX and the other biotic indices are signi cantly correlated with harbour characteristics, maritime tra c and edaphic factors (organic matter and chemical contamination). The present study gives an overview of all available benthic data, the impact of biological invasions and the ecological quality status of harbours in the Gulf of Gabès. The results could be considered as providing important baseline data for the implementation of environmental policies and management plans in the future.
