Carbon Dioxide as a Sex-determining Factor in Moina Macrocopa

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...

A new report of Moina macrocopa (Straus, 1820) (Cladocera, Anomopoda) in South America.

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...

Four Transgenerational Demographic Performance of Moina macrocopa Exposed to Chronic Levels of Cadmium

In this study, we quantified intergenerational, demographic variability of Moina macrocopa subjected to cadmium stress. Exposure of M macrocopa to cadmium (0.2, 0.3, and 0.4 mg/L as CdCl2) through 4 consecutive generations revealed changes in demographic responses not only in survivorship variables but also in reproductive parameters. Long-term demographic responses varied differently, dependin...
