The Impact of Detergents on the Mortality of Daphnia magna

open access: yes‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 1998
This study aimed to examine the impact of detergents on the mortality rate of Daphnia magna. For this purpose, we exposed one-day-old Daphnia magna for 24 hours to six nationwide consumed detergents, comprising of two dishwasher detergents, three washing-

Diet quality determines interspecific parasite interactions in host populations [PDF]

open access: yes, 2014
The widespread occurrence of multiple infections and the often vast range of nutritional resources for their hosts allow that interspecific parasite interactions in natural host populations might be determined by host diet quality. Nevertheless, the role

Prediction of chronic toxicity of pharmaceuticals in Daphnia magna by combining ortholog prediction, pharmacological effects, and quantitative structure-activity relationship

open access: yesEcotoxicology and Environmental Safety
To develop a method for predicting chronic toxicity of pharmaceuticals in Daphnia, we investigated the feasibility of combining the presence of drug-target orthologs in Daphnia magna, classification based on pharmacological effects, and ecotoxicity ...

Transgenerational effects of microcystin-LR onDaphnia magna [PDF]

open access: yesJournal 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.

Possible Causes of Extreme Variation of Benzo[a]pyrene Acute Toxicity Test on Daphnia magna

open access: yesToxics
There are enormous differences in benzo[a]pyrene (BaP) acute toxicity tests on Daphnia magna, according to previous publications. The explanations of the reasons for this extreme variation are necessary.

Responses of a bacterial pathogen to phosphorus limitation of its aquatic invertebrate host [PDF]

open access: yes, 2008
Host nutrition is thought to affect the establishment, persistence, and severity of pathogenic infections. Nutrient-deficient foods possibly benefit pathogens by constraining host immune function or benefit hosts by limiting parasite growth and ...

Effects of Short-term Low Intensity Laser and Ultraviolet Radiation on Embryos of Daphnia Magna [PDF]

open access: yesЖурнал 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 ...
