Assimilation of Diaphanosoma brachyurum and Moina macrocopa on Microcystis.

Accelerated ecotoxicity of photoreactive nanoparticles on Moina macrocopa

Zinc oxide nanoparticles (ZnO NPs) and titanium dioxide nanoparticles (TiO2 NPs) are well known as photoreactive nanoparticles (NPs). Various phototoxicities of ZnO NPs and TiO2 NPs were reported on several organisms. It was still necessary to evaluate the toxicity of photoreactive ZnO NPs and TiO2 NPs due to species-specific effects under various irradiation conditions. We compared the acute t...

Carbon Dioxide as a Sex-determining Factor in Moina Macrocopa

On the first record of the exotic Moina macrocopa (Straus, 1820) in Minas Gerais State, Brazil.

Sampling at Pampulha Reservoir in Minas Gerais State in August of 2012 found Moina macrocopa, until now reported for South America only in a temporary pond in Rio de Janeiro State, Brazil (Elmoor-Loureiro et al., 2010) and similar environments in South America (Valdivia-Villar, 1988; Elias-Gutiérrez and Zamuriano-Claros, 1994; Paggi, 1997). The most recent inventory (checklist) of cladocerans f...

Population growth and development of two species of Cladocera, Moina micrura and Diaphanosoma birgei, in laboratory.

The objective of the present work was to investigate the influence of four diets on population growth, development, total length, dry weight, and nutritional value of two zooplanktonic species, Moina micrura and Diaphanosoma birgei. The four dietary treatments were: algae alone (A); algae + vitamins (AV); algae + ration (AR); and algae + ration + vitamins (ARV). Growth rate peak for both specie...
