Identification of Microcrustaceans as Potential Bioindicators of Arsenic in Tropical Water Bodies
Archives of Environmental Contamination and Toxicology, 2022We investigated microcrustaceans inhabiting arsenic contaminated and non-contaminated freshwater to identify potential bioindicators of arsenic contamination in the tropical freshwater of Matehuala in northern Mexico. We collected water, sediment, and zooplankton, at five sampling points during three sampling campaigns. We determined water temperature,

Microcrustaceans are a large group of very small animals that often turn up in samples from rivers, ponds and wetlands. Because they are so small, we only ever see their largest representatives.

Thioredoxins, with a dithiol/disulfide active site (CGPC) are major highly conserved and ubiquitous proteins that are involved in protecting organisms against various oxidative stresses. In the present study, a novel thioredoxin gene was identified in antarctic microcrustacean, Euphausia superba (designated as EsTrx1). The full-length cDNA sequences of

Patterns in the Composition of Arctic Tundra Pond Microcrustacean Communities
Canadian Journal of Fisheries and Aquatic Sciences, 1986On the basis of intensive collections of Microcrustacea (Cladocera, Copepoda, Anostraca, and Notostraca) from 11 sites in the Canadian arctic archipelago, patterns of species richness, distribution, and community composition were evaluated. Microcrustacean communities of pond habitats in the high arctic of Canada are much less diverse than communities ...

Acidity versus habitat structure as regulators of littoral microcrustacean assemblages
Freshwater Biology, 2007Summary1. Emergence traps were set overnight on the sediment surface to sample the littoral microcrustaceans of 22 Canadian Shield lakes that ranged in pH from 4.56 to 6.92. Traps were randomly allocated in quintuplicate in both wave‐washed sandy habitats where pipewort (Eriocaulon septangulare) was the dominant macrophyte (termed pipewort habitats ...

Can large branchiopods shape microcrustacean communities in Mediterranean temporary wetlands?
Marine and Freshwater Research, 2011It was recently suggested that large branchiopods may play a keystone role in temporary aquatic habitats. Using a microcosm experiment manipulating microcrustacean communities of Mediterranean temporary wetlands (Camargue, Southern France), we tested the following hypotheses: (i) large branchiopods (the notostracan Triops cancriformis and the ...

We identify littoral microcrustacean indicators of acidification in 2 surveys of Canadian Shield lakes conducted 10 years apart. We found a total of 90 cladoceran and copepod species with richness increasing severalfold from acidic to nonacidic lakes. The fauna of the nonacidic lakes differed between the surveys. The 1987 survey employed activity traps,

Microcrustacean prey and macroinvertebrate predators in a stream food web
Freshwater Biology, 1995SUMMARY1. The consumption of microcrustacea by two polyphagous predators, larvae of the caddisfly Plectrocnemia conspersa (Curtis) and the alderfly Sialis fuliginosa Pictet, was investigated in an English stream with a well‐known macro‐ and microinvertebrate fauna.
