Analysis of DNA Methylation and Hydroxymethylation in the Genome of Crustacean Daphnia pulex.
The aim of our study was to analyze the presence of 5-methyl-cytosine (5-mC) and 5-hydroxymethyl-cytosine (5-hmC) in the genome of crustacean Daphnia pulex. First, the presence of 5-mC and 5-hmC in genomic DNA was demonstrated by using antibodies specific to either 5-mC or 5-hmC. Then, analysis of 5-mC and 5-hmC using pairs of restriction enzymes with different sensitivity to methylation and hy...
متن کاملPopulation Genomics of Daphnia pulex.
Using data from 83 isolates from a single population, the population genomics of the microcrustacean Daphnia pulex are described and compared to current knowledge for the only other well-studied invertebrate, Drosophila melanogaster These two species are quite similar with respect to effective population sizes and mutation rates, although some features of recombination appear to be different, w...
متن کاملFood chain effects of sublethal ultraviolet radiation on subarctic Daphnia pulex – a field and laboratory study
In shallow subarctic ponds Daphnia and their algal food are often exposed to solar ultraviolet radiation (UVR). It was previously demonstrated that direct exposure of Daphnia to UVR may result in sublethal damage to Daphnia‘s intestinal system. This led to the hypothesis that, as consequences of such exposures, Daphnia may be experiencing a situation similar to starvation. We examined, in contr...
متن کاملBiotic ligand model of the acute toxicity of metals. 2. Application to acute copper toxicity in freshwater fish and Daphnia.
The biotic ligand model (BLM) was developed to explain and predict the effects of water chemistry on the acute toxicity of metals to aquatic organisms. The biotic ligand is defined as a specific receptor within an organism where metal complexation leads to acute toxicity. The BLM is designed to predict metal interactions at the biotic ligand within the context of aqueous metal speciation and co...
متن کاملField dissipation and plant uptake of benzotriazole ultraviolet stabilizers in biosolid-amended soils.
Benzotriazole ultraviolet stabilizers (BUVSs) have been commonly used in industrial and household product formulations, and have been detected in biosolids from wastewater treatment plants. However, little is known about their occurrence and dissipation behavior in the soil environment associated with biosolid application. This study investigated the occurrence and dissipation of five typical B...
