Journal of Applied Sciences and Environmental Management, 2011 A bioassay utilizing the cladoceran Daphnia magna hatching success is presented for testing the toxicity of acid mine drainage (AMD) sediments. AMD sediments contain complex mixtures of potential toxins and a rapid, sensitive bioassay is valuable for ...

Sucralose Induces Biochemical Responses in Daphnia magna
PLoS ONE, 2014 The intense artificial sweetener sucralose has no bioconcentration properties, and no adverse acute toxic effects have been observed in standard ecotoxicity tests, suggesting negligible environmental risk. However, significant feeding and behavioural alterations have been reported in non-standard tests using aquatic crustaceans, indicating possible ...

Transgenerational effects of microcystin-LR onDaphnia magna [PDF]
Journal of Experimental Biology, 2012 SUMMARYAnthropogenic and climate factors increase the frequency of problematic cyanobacterial blooms in freshwater. Among other toxins, some cyanobacteria produce microcystins (MCs), which inhibit phosphatases type 1 and type 2A and provokes oxidative stress.

Food Frontiers, Volume 7, Issue 2, March 2026.ABSTRACT Medicago sativa L. (alfalfa) harbors a remarkably diverse reservoir of bioactive secondary metabolites. Flavonoids, isoflavones, and triterpenoid saponins dominate its bioactivity landscape, driving potent antioxidant, anti‐inflammatory, antimicrobial, estrogenic, hypolipidemic, and cytotoxic actions through redox modulation, membrane ...

Effects of Chronic Waterborne Nickle Exposure on Two Successive Generations of \u3cem\u3eDaphnia Magna\u3c/em\u3e [PDF]
, 2004 In a 21-d chronic toxicity test in which an F0 generation of Daphnia magna were exposed to waterborne Ni, the noobservable-effect concentration (for survival, reproduction, and growth) was 42 μg Ni L-1, or 58% of the measured 21-d median lethal ...

Chemistry &Biodiversity, Volume 23, Issue 2, February 2026.This study investigates the phytochemical composition and biological activities of a hydroalcoholic extract of Haloxylon articulatum. LC‐HRMS/MS identified diverse bioactive compounds, notably N‐caffeoyltyramine and sinapoyltyramine. The extract exhibited strong antioxidant activity and significant cytotoxic effects against gastric cancer cell lines ...

Effects of Short-term Low Intensity Laser and Ultraviolet Radiation on Embryos of Daphnia Magna [PDF]
Журнал Сибирского федерального университета: Серия Биология, 2011 Short-term impact of the low intensity electromagnetic radiation on in vitro growing Daphnia magna Straus embryos was studied. Embryos were exposed to laser radiation (633 nm, 0.05 mW/cm2) and ultraviolet radiation (365 nm, 0.16 mW/cm2) separately as ...

Ökologische und genetische Differenzierung von Daphnia-galeata-Populationen in Europa [PDF]
, 2005 Here I analyse 23 populations of D. galeata, a large-lake cladoceran, distributed mainly across the Palaearctic. I detected high levels of clonal diversity and population differentiation using variation at six microsatellite loci across Europe.

Isolation mediates persistent founder effects on zooplankton colonisation in new temporary ponds [PDF]
, 2017 Understanding the colonisation process in zooplankton is crucial for successful restoration of aquatic ecosystems. Here, we analyzed the clonal and genetic structure of the cyclical parthenogenetic rotifer Brachionus plicatilis by following populations ...
