Artemia salina: A microcrustacean to assess engineered nanoparticles toxicity
Microscopy Research and Technique, 2020 AbstractThe focus of this work was to investigate the toxicity of different metal nanoparticles (gold nanoparticles [AuNPs], silver nanoparticles [AgNPs], titanium dioxide nanoparticles [TiO2NPs]) on brine shrimp Artemia salina. We investigated if nanoparticles could have an influence on hatching of cysts and on mortality of larvae. Larvae (also called

Population growth of microcrustaceans in water from habitats with differing salinities
PeerJ, 2021 Inland salt marshes are a rare habitat in North America. Little is known about the invertebrates in these habitats and their ability to cope with the brackish conditions of the marsh. We studied the population growth of ostracods found in an inland salt marsh (Maple River salt marsh) and of copepods found in the wetland habitat immediately adjacent to ...

Vertical distribution of zooplankton in a shallow peatland pond: the limiting role of dissolved oxygen [PDF]
, 2013 We investigated the diel vertical distribution patterns of microcrustacean zooplankton (Cladocera, Copepoda) in a shallow pond (max. depth: 70 cm) of the Öreg-turján peatland (Ócsa, Central Hungary) during three 24-h periods in July (19–20th), August (17–

Gill Ventilation Rates of Mayfly Nymphs (Ephemeroptera: Heptageniidae) as a Biomonitoring Technique [PDF]
, 2018 Gill ventilation frequency (GVF) of the mayfly nymph Stenacron interpunctatum (Ephemeroptera: Heptageniidae) was studied to assess the applicability of a relatively simple, real time video methodology and to assess the potential of GVF rates for use in a

Mathematics, 2020 A simple mathematical model capable of reproducing formation of small-scale spatial structures in prey–predator system is presented. The migration activity of predators is assumed to be determined by the degree of their satiation. The hungrier individual
