Copper and zinc detoxification in Gammarus pulex (L.)

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...

Gammarus 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 ...

The Effect of Ionic Copper on the Oxygen Consumption of Gammarus Pulex and Polycelis Nigra

Abnormalities in sexual development of the amphipod Gammarus pulex (L.) found below sewage treatment works.

Increasing numbers of widely used industrial, agricultural, and natural chemicals are known to elicit endocrine-disrupting effects in a wide range of vertebrate and invertebrate species. The objective of this study was to determine whether the sexual development of the freshwater crustacean Gammarus pulex (L.) was affected below sewage treatment works (STW) previously known to contain endocrine...

Heliospora 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 ...
