Modeling combined effects of pulsed exposure to carbaryl and chlorpyrifos on Gammarus pulex.
Aquatic risk assessment can be improved if we are able to quantitatively predict the effects resulting from sequential pulsed exposure to multiple compounds. We evaluate two modeling approaches, both extended to suit multiple compounds, the semi-mechanistic threshold damage model (TDM), and a model based on time-weighted averages (TWA). The TDM predicts that recovery of damage to Gammarus pulex...
متن کاملPopulation responses of the freshwater amphipod Gammarus pulex (L.) to an environmental estrogen, 17alpha-ethinylestradiol.
The effects of the environmental estrogen 17alpha-ethinylestradiol (EE) on mixed populations of 90 individual Gammarus pulex were examined following a 100-d exposure in a flow-through system. Counts of total animal numbers revealed that, in all treatment groups, population size dramatically increased due to recruitment, with neonate and juvenile gammarids the most abundant. At concentrations of...
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 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 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 ...
