TLDR
A microcosm experiment was carried out to determine how benzo(a)pyrene (BaP) may affect marine meiofauna community, with a main emphasis on nematode structure and functional traits, and revealed a gradual decrease in the abundance of all meiobenthic groups, except for isopods.
Effectiveness of Shewanella oneidensis bioaugmentation in the bioremediation of phenanthrene-contaminated sediments and possible consortia with omnivore-carnivore meiobenthic nematodes.
TLDR
The results obtained showed that the bioaugmentation with Shewanellea oneidensis was highly effective in reducing the negative impact of the highest dose of phenanthrene tested on meiobenthic nematodes.
Toxicity of hydroxychloroquine, a potential treatment for COVID-19, on free-living marine nematodes
TLDR
A closed microcosm study on the responses of the nematodes 2B and the corresponding taxa are bioindicative of current- or post-COVID-19 crisis risks in relation with the bioaccumulation of HCQ in seafood.
Do presence of gray shrimp Crangon crangon larvae influence meiobenthic features? Assessment with a focus on traits of nematodes
TLDR
The results suggested that juvenile shrimp had a significant negative impact on the abundance of nematodes and copepods, but no effect on polychaetes.
Ecotoxicity of polybrominated diphenyl ether (BDE-47) on a meiobenthic community with special emphasis on nematodes: Taxonomic and trophic diversity assessment.
TLDR
The response taxonomic and trophic of meiobenthic organisms, especially marine nematodes to polybrominated diphenyl ether (BDE-47) was studied using a community from Bizerte lagoon, and the control microcosm was dominated by microvores, represented by two species of Terschellingia.
Ecotoxic response of nematodes to ivermectin, a potential anti-COVID-19 drug treatment
TLDR
Trophic Diversity and Amphideal Diversity index values increased with sedimentary ivermectin enrichment and the responses of the functional type 2A-REL-Sp and corresponding taxa predict post-COVID-19 environmental concerns and the bioaccumulation of iverMectin in seafoods.
The individual and combined effects of cadmium, polyvinyl chloride (PVC) microplastics and their polyalkylamines modified forms on meiobenthic features in a microcosm.
TLDR
The results obtained showed that individual treatments of cadmium, polyvinyl chloride and PVC were toxic for meiofauna and particularly for free-living nematodes, and binary combinations of contaminants have a lesser toxic effect compared to their individual effects.
Nematode traits after separate and simultaneous exposure to Polycyclic Aromatic Hydrocarbons (anthracene, pyrene and benzo[a]pyrene) in closed and open microcosms.
TLDR
The results revealed that single PAHs impacted the nematofauna similarly in closed or open systems with a higher toxicity observed for benzo[a]pyrene, and the use of open systems is preferred to closed ones as the research outcomes were more accurate and representing better conditions prevailing in nature.

An experimental protocol to select nematode species from an entire community using progressive sedimentary enrichment
TLDR
An innovative protocol for selecting a single species from an entire community of nematodes using two independent selection processes whereby the sediment of the microcosms is progressively and separately enriched with fine and coarse sediment fractions is proposed.
Experimental studies with nematodes in ecotoxicology: an overview.
TLDR
An overview of the various existing ecotoxicological tools for nematodes, ranging from molecular laboratory methods to experimental model ecosystem approaches, and their role as indicator organisms is given.
The effects of carbamazepine on macroinvertebrate species: Comparing bivalves and polychaetes biochemical responses.
TLDR
Comparing both species, it seems that S. plana was the most sensitive species since stronger biochemical alterations were observed in this species, especially at the highest CBZ concentrations.
Metabolic responses to anabiosis in the fourth stage juveniles of Ditylenchus dipsaci (Nematoda)
  • J. Barrett
  • Biology
    Proceedings of the Royal Society of London. Series B. Biological Sciences
  • 1982
TLDR
The fourth stage juveniles of the stem nematode Ditylenchus dipsaci can lose almost all of their body water and survive in an anabiotic state for long periods of time and there is evidence that for some time after hydration the mitochondria are essentially uncoupled.
Morphometry, energetics and diversity of free-living nematodes from coasts of Bizerte lagoon (Tunisia): an ecological meaning
TLDR
Analyses of water quality in the Bizerte lagoon showed their relative low oxygenation during September 2002 compared to December 2001, and Shannon-Wiener diversity index values were the lowest in the South-Western stations characterized by higher level of organic matter and a weaker effect of pollution.
Glutathione S-transferase in the defence against pyrethroids in insects.
TLDR
Inhibition studies combined with competitive fluorescence spectroscopy and high pressure liquid chromatography showed that the insecticide binds probably to the active site of the enzyme inhibiting its activity towards CDNB in a competitive manner, but is not conjugated with GSH.
Colonisation of various types of sediment by estuarine nematodes via lateral infaunal migration: a laboratory study
TLDR
The outcome of this study demonstrated that the colonisation of defaunated sediment via lateral interstitial migration is a directed, species-specific process that can lead to the establishment of colonist communities that are significantly different from source communities.
Trehalose metabolism genes in Caenorhabditis elegans and filarial nematodes.
TLDR
The role of trehalose metabolism in nematodes is investigated, using Caenorhabditis elegans as a model, and complementary DNA clones putatively encoding genes involved intrehalose pathways in filarial nematode are identified.
Insecticide Susceptibility and Detoxication Enzyme Activities in Permethrin-Selected Diamondback Moths
TLDR
The results indicated that pyrethroid resistance observed in this strain was most likely attributed to decreased target site sensitivity.
Permethrin-induced oxidative stress and toxicity and metabolism. A review.
TLDR
This review summarises the research conducted over the past decade into the reactive oxygen species (ROS) generation and oxidative stress as a consequence of PER treatments, and ultimately their correlation with the toxicity and the metabolism of PER.
