Effects of hydrocarbon contamination on a free living marine nematode community: results from microcosm experiments.
TLDR
Results from multivariate analyses of the species abundance data demonstrated that responses of nematode species to the diesel treatments were varied, and Marylynnia stekhoveni seemed to be a "diesel-resistant" species.
Effects of Increasing Levels of Nickel Contamination on Structure of Offshore Nematode Communities in Experimental Microcosms
TLDR
Results showed significant differences between nematode assemblages from undisturbed controls and those from nickel treatments, and most univariates measures, including diversity and species richness, decreased significantly with increasing level of Ni contamination.
Laboratory Study on Individual and Combined Effects of Cobalt- and Zinc-Spiked Sediment on Meiobenthic Nematodes
Free-living nematodes are the most abundant taxa among the meiobenthos and the predominant prey for bottom-feeding fishes. They are able to accumulate toxicants from sediments which explain their use
Functional organization of the benthic macrofauna in the Bizerte lagoon (SW Mediterranean Sea), semi-enclosed area subject to strong environmental/anthropogenic variations.
TLDR
L'ecosysteme presente des signes de desequilibre trophique et la communaute macrobenthique est tres appauvrie, malgre le bon etat ecologique apparent montre par les indices biotiques.
Individual and combined effects of cadmium and diesel on a nematode community in a laboratory microcosm experiment.
TLDR
Results from multivariate analyses of the species abundance data demonstrated that responses of nematode species to the cadmium-diesel treatments were varied: Marylynnia stekhoveni, Calomicrolaimus honestus and Oncholaimellus mediterraneus were significantly affected but they were not eliminated.
Mussel-farming effects on Mediterranean benthic nematode communities
TLDR
It is suggested that site-specific hydrodynamic and biogeochemical conditions should be taken into account when planning new mussel farms, and meiobenthic communities should be monitored before and after farm development to prevent excessive modifications of benthic assemblage structure.
An Assessment of the Impact of Chromium-Amended Sediment on a Marine Nematode Assemblage Using Microcosm Bioassays
TLDR
Results from multivariate analyses demonstrated that responses of nematode species to chromium treatments were varied, and such “opportunistic” and “resistant” species could be used as sensitive indicators of unsafe marine food.
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.
Metabarcoding free‐living marine nematodes using curated 18S and CO1 reference sequence databases for species‐level taxonomic assignments
TLDR
Genus‐level assignments using ASVs exhibited higher accuracy and lower error rates compared to species‐ level assignments, suggesting that this is the most reliable pipeline for rapid assessment of alpha diversity from environmental samples.
Individual and combined effects of lead and zinc on a free-living marine nematode community: Results from microcosm experiments
TLDR
Both univariate and multivariate analyses of the data showed that the differential response occurred in all treatments but the communities from microcosms contaminated with lead and zinc separately were much more strongly affected, suggestive of antagonistic interactions between Pb and Zn.
