“…The species in question belong to the collection of Ayari and Zaâbi (RF in Table 1). 3-Research on polychaetes and studies dealing with macrobenthic fauna, which were published after the last complete inventory of Tunisian polychaetes due to Ayari et al (2009), are revised and collated here, especially the data of Diawara et al (2008), Pérez-Domingo et al (2008, Ayari et al (2009), Zaâbi et al (2009Zaâbi et al ( , 2010Zaâbi et al ( , 2012, Khedhri et al (2014Khedhri et al ( , 2016Khedhri et al ( a, b, 2017, Mosbahi et al (2015Mosbahi et al ( a, b, 2017, Ounifi-Ben Amor et al (2015), Boudaya et al (2019), and Chaibi et al (2019.

“…A new species was described from this same sector of the Tunisian coast and a new species was reported for the Mediterranean Sea (Chaibi et al, 2019 and2021, respectively). Other taxonomic and especially ecological studies have been conducted over the last decade in the Gulf of Gabès (Pérez-Domingo et al, 2008;Aloui-Bejaoui & Afli, 2012;Khedhri et al, 2014Khedhri et al, , 2016aKhedhri et al, , b, 2017aMosbahi et al, 2015aMosbahi et al, , b, 2016Mosbahi et al, , 2017Boudaya et al, 2019); these studies have led to the recording of several new polychaete species compared to the inventory of Ayari et al (2009).…”

The last inventory of Tunisian polychaetes diversity by Ayari et al. (2009) is updated. New records were acquired from the literature and from the current study concerning species collected in the tidal channels of the Gulf of Gabès (2016-2017) and the re-examination of some species deposited in the collection of the Tunisian National Institute of Marine Sciences and Technologies. This inventory, reviewing the taxonomy, nomenclature, and biogeographic distribution of the Tunisian polychaetes, includes 390 species belonging to 52 families, among which the Serpulidae (41 species) and Syllidae (36 species) are the most diverse. In total, 37 species previously reported are currently removed from the Tunisian polychaetes list. An additional 121 new species are added, including 23 species collected in the tidal channels and 6 species in the reference collection previously misidentified as their congeners. Morphological differences between the latter are briefly discussed and figured. Among these species, Laonice bahusiensis, Laonice norgensis, and Scolelepis neglecta are extending their Mediterranean distribution, while Sternaspis thalassemoides and Caulleriella mediterranea are probably reported for the first time after their original description. In addition, this current inventory allows us to discuss the establishment status of 17 Non-Indigenous polychaete species (14 established, 1 casual, and 2 cryptogenic) found in Tunisian waters.

“…Heavy metal pollution is one of the most common anthropogenic pressures that impact marine ecosystems (e.g., intertidal zones, coastal waters, and estuaries), which has been documented by many studies throughout the world (Boudaya et al, 2019;Izegaegbe et al, 2020;Wang et al, 2020). Heavy metal contaminants can result in adverse toxic effects on benthic organisms (Dewitt et al, 1996;Dabney et al, 2018), leading to the changes in composition, structure, and ecosystem function of macrobenthic communities (Mucha et al, 2003;Piló et al, 2016;Hu et al, 2019;Roe et al, 2020;Dreujou et al, 2021).…”

Functional Trait Responses of Macrobenthos to Anthropogenic Pressure in Three Temperate Intertidal Communities

et al. 2021

With the increasing impact of human activities on marine ecosystems, there is a growing need to assess how the components of marine ecosystems (e.g., macrobenthos) respond to these anthropogenic pressures. In this work, the trait-based approach was used to assess the effects of anthropogenic pressures represented by the area of land-based aquaculture pond (Pond Area) and heavy metals on the macrobenthic communities in three intertidal zones[Aoshan Bay (AO), Wenquan River and Daren River (RW), and Xiaodao Bay (XD)] of Laoshan Bay, Shandong Peninsula, China. Compared with RW and XD, AO was under more pressure in terms of the average concentrations of heavy metals and total organic carbon (TOC) in sediments and also in the Pond Area. Fuzzy correspondence analysis (FCA) showed that there were significant differences in the composition of functional traits among the three regions (PERMANOVA; p < 0.05). In the highly polluted area, macrobenthic communities exhibited a combination of traits, such as relatively short life span, weak mobility, feeding on deposits, and more tolerant to organic matter, whereas in a less polluted area, they exhibited a combination of traits, such as relatively long life span, relatively high mobility, and more sensitivity to organic matter. The RDA results showed that the distribution of the trait modalities was significantly affected by heavy metals (Hg and Cd), TOC, Pond Area, and sampled location. Variation partitioning analysis (VPA) indicated that the shared influence of sediment-related pollution factors and Pond Area contributed most to the variance of the functional traits, which implied that human activities directly and/or indirectly lead to changes in functional traits of macrobenthic communities in the intertidal zones.

“…The Gulf of Gabès (southern Tunisia) includes the highest number of harbours in Tunisia; it is considered as one of the most vulnerable aquatic ecosystems in the Mediterranean Sea, mainly caused by biological invasions (Ouni -Ben Amor, 2016). Moreover, intensive anthropogenic pressures due to trawling practices, diverse pollution (e.g phosphogypsum inputs, industrial and urban wastes) and shipping activities have led to major environmental problems (Hattab et al, 2013;Boudaya et al 2019;Mosbahi et al 2019). Among the different taxonomic groups, macrobenthic invertebrates have been largely used as bio-indicators for aquatic monitoring because they respond rapidly to anthropogenic and natural stressors (Blanchet et al 2008;Dauvin et al 2012Dauvin et al , 2017.…”

“…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.
