“…Only three functional traits (body length, feeding group, and amphid shape), presented a clear difference between the untreated and treated microcosms. The nMDS second-stage ordination of inter-matrix rank correlations indicated that the amphideal shape was the most modified functional trait [46]. Finally, a study examining the single and binary PAHs (anthracene, pyrene, and benzo[a]pyrene) toxicity on marine nematodes have demonstrated that the single or mixtures treatments exhibited restructuring of trophic diversity with an increase of epigrowth-feeders abundance.…”

Marine ecosystems have great economic and ecological value, as they provide good services and habitats for a variety of organisms. However, the marine environment is under anthropogenic stressors. The Mediterranean basin is one of the most threatened ecosystems, where urban and industrial waste is becoming a growing risk for coastal marine habitats integrity. The Bizerte lagoon represents a major coastal lagoon and is an example of such an aquatic environment continuously exposed to pollutants. Marine nematodes are the most diverse metazoans and represent an excellent model for the environmental monitoring because they can be easily sampled and maintained under experimental conditions. Nematode communities are investigated for the analysis of taxonomic diversity and ecological indices. Currently, we present here to evaluate the ecological quality based on the description of nematode assemblages using biological traits and functional groups. This relatively new approach allows obtaining insight into the status of marine coastal ecosystems.

“…Recently, Nasri et al investigated the meiobenthic response to the polybrominated diphenyl ether (BDE-47) exposure in laboratory during one month [50]. BDE-47 caused a decrease in the bacterial abundance, and the nematodes taxonomic diversity as well as a change of all functional traits abundance, especially, the feeding group, amphid shape, and adult length were the most affected.…”

Marine ecosystem represents an ecologically and economically important water bodies for human and animal living. Their increasing pollution by persistent organic pollutants has represented a major environmental alarm during the last years. In the current study, we examined the occurrence, local distribution and ecotoxicological menace of organic pollutants, comprising brominated flame retardants (BFR), polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and organochlorine pesticides (OCPs) in different matrices from the Northern Tunisian Coastal Ecosystem (Bizerte lagoon). The pollutant existence in this biome is related with a negative impact on the biocenosis health. Many approach including (i) chemical analyses; (ii) taxonomic structure and ecological indices analyses; (iii) and biochemical experimental studies, were investigated to determine the ecosystem quality and the contaminant effects. Our chapter introduces the baseline information on the organic contaminations extent and toxicological impact, as well as, it contribute to evaluate the ecological quality of this marine coastal ecosystem.
