In this study, the association between the acute toxicity of 15 compounds to Daphnia magna, expressed as 24- and 48-h LC(50) values, and the corresponding oral LD(50) values for the rat was tested. Since there was evidence of a strong relationship between the two species, the sample was extended to 54 cases by including the values for acute toxicity to D. magna and rat of more chemicals publish...

recently, some natural products have been used in the fields as alternative to synthetic compounds, to minimize the negative impacts to the environment. this study aimed to verify the effects of neem-based bio-pesticide in causing acute toxicity for a fish and chronic toxicity for a microcrustacean. to this end, danio rerio and daphnia magna were exposed to various concentrations of a neem-base...

Endocrine disruption is intimately linked to controlling the population of pollutant-exposed organisms through reproduction and development dysregulation. This study investigated how endocrine in a predator organism could affect prey species biology infochemical communication. Daphnia magna Chlorella vulgaris were chosen as model planktons, respectively, fenoxycarb was used for disrupting syste...

This study assesses the potential of cladocerans as competitors for controlling the oviposition and larval abundances of mosquitoes. Control of mosquito larvae involving the use of antagonists has focused mostly on predators. We hypothesized that cladoceran competitors have a strong potential to control larval populations of some species of mosquitoes that can be early colonizers of newly-fille...
