Inheritance during parthenogenesis in Daphnia magna.

Microinjection-Based RNA Interference Method in the Water Flea, Daphnia pulex and Daphnia magna

It is well known that most daphnid species have several attractive life history characteris‐ tics such as cyclical parthenogenesis, environmental sex determination, and predator-in‐ duced defense formation. Recent advances in high-throughput omics technologies make it easy to obtain a huge number of potential candidate factors involved in environmental stimuli-triggered phenotypic alterations. ...

Evaluation of silver nanoparticles toxicity in Daphnia magna: Comparison of chemical and green biosynthetic productions

Recently nanoparticles, particularly silver nanoparticles, are broadly used in industry, hence the contamination of the environment with AgNPs has caused considerable concern. In this study, the toxicity of biosynthetic nanosilver produced by two macroalgae: Sargassum boveanum and Ulva flexuosa extracts were compared with chemical nanosilver in Daphnia magna. Size and quality of nanoparticles e...

Local adaptation of sex induction in a facultative sexual crustacean: insights from QTL mapping and natural populations of Daphnia magna.

Dormancy is a common adaptation in invertebrates to survive harsh conditions. Triggered by environmental cues, populations produce resting eggs that allow them to survive temporally unsuitable conditions. Daphnia magna is a crustacean that reproduces by cyclical parthenogenesis, alternating between the production of asexual offspring and the sexual reproduction of diapausing eggs (ephippia). Pr...

Short communication-Survey of Methyl Tertiary Butyl Ether (MTBE) toxicity using bioassay on Daphnia magna

Effects of n3-HUFA enriched Daphnia magna on growth, survival, stress resistance, and fatty acid composition of larvae of Persian sturgeon (Acipenser persicus)

Effects of Daphnia magna enriched with cod liver oil (CLO) as a source of highly unsaturated fatty acid (HUFA) on growth, survival, stress resistance, and fatty acid composition of the Persian sturgeon larvae were evaluated. Daphnia enriched for three different time periods (3, 6, and 9 hours) and non-enriched Daphnia were fed to the Persian sturgeon larvae (average weight 61.6±0.4mg) during 14...
