Toxicity of fluoroquinolones on the cladoceran Daphnia magna

Water Environment Research, 2021
AbstractThis study evaluates the acute and chronic toxicological effects of six fluoroquinolones on the mortality and growth of Daphnia magna. The NOECs calculated with the multivariate Probit regression model for the chronic study were 56 μg/L ciprofloxacin, 63 μg/L enrofloxacin, 78 μg/L levofloxacin, 85 μg/L marbofloxacin, 69 μg/L norfloxacin, and ...

A circadian rhythm in Daphnia magna

Oecologia, 1971
In 1963 Harris reported a circadian rhythm of 28 hours in Daphnia magna (Crustacea, Cladocera). Many endogenous periodicities have been described, mostly in vertebrates and plants, seldom in planktonic crustaceans, but a free-running period of 28 hours in continuous light is never a common phenomenon.

Ecotoxicity of pp’DDE to Daphnia magna

Ecotoxicology, 2013
pp'-Dichlorodiphenyl-dichloroethylene (pp'DDE), a metabolite of pp'-dichlorodiphenyl-trichloroethane poses a risk for many ecosystems in spite of the banning of the parent compound because of its persistence and bioaccumulability. Nevertheless, the knowledge of acute and chronic toxicity on aquatic organisms is still very poor.

Biotransformation and bioconcentration of pyrene in Daphnia magna

Aquatic Toxicology, 2003
Water fleas (Daphnia magna) were exposed to [14C]pyrene in the presence and absence of piperonyl butoxide (PBO), a general cytochrome P450 (CYP) inhibitor, in organic carbon-free artificial freshwater (AFW ...

Macromolecular isoforms of Daphnia magna haemoglobin

Biological Chemistry, 2005
The haemoglobin (Hb) of Daphnia magna acclimated to different oxygen conditions was sampled, and in its natively assembled state it was separated by chromatofocusing. The Hb isoforms were analysed for their subunit composition under denaturating conditions by two-dimensional gel electrophoresis.
