Copper and zinc detoxification in Gammarus pulex (L.).
To negate the toxicity of labile intracellular metals, some aquatic organisms partition metals into specific subcellular locations for detoxification, namely the soluble heat-stable cytosol and insoluble metal-rich granules. The aim of the present study was to characterise these subcellular storage sites in the freshwater crustacean Gammarus pulex (Linnaeus) following in situ exposures upstream...
متن کاملTranscriptome of the freshwater amphipod Gammarus pulex hepatopancreas
So far, ecotoxicological studies used biomarkers of exposure or of effects in order to investigate the impacts of contaminated areas on biota (Peakall, 1994 [6]). However, although these results are important in the ecotoxicological risk assessment, biomarkers are very specific and only provide information on the biological processes or physiological pathways targeted by the biomarkers experime...
متن کاملHeliospora n.g. and Rotundi^ta n.g., Gregarines of Gammarus pulex
THE gregarines of Gammarus pulex L. have long been known, in fact they were some of the earliest of these Sporozoa to be observed (Text-figs. 1-3). However,.so far, no adequate description has been given of the gametes and spores which are the most important stages from the systematic point of view. Lady Muriel Percy, who worked in this Department from 1925 to 1929, helped in the investigation ...
متن کاملGammarus pulex (L.) feeding bioassay--effects of parasitism.
Taylor et al. (1993) described a pollutant bioassay based upon a change in the rate at which Gammarus pulex (L.) consumes a novel food source (eggs of the brine shrimp Anemia salina) when the animals are stressed by exposure to a pollutant. The bioassay is rapid and non-destructive, and produces results with less variation than reported using conventional leaf-feeding bioassays. However, it is ...
متن کاملCondition-dependent ecdysis and immunocompetence in the amphipod crustacean, Gammarus pulex.
The exoskeleton of arthropods forms an efficient protection against pathogens, but this first line of defence is periodically weakened during ecdysis, increasing the opportunity for surrounding pathogens to invade the body cavity. Since the richness of pathogens in the environment can be spatially and temporally variable, arthropods may have a fitness advantage in moulting in a place and time o...
