“…Hence, their actual exposure concentrations may have been much lower than the nominal concentrations (e.g., by adsorption to test vessel walls or particulate matter). In addition, differences found between different studies testing the sensitivity to cadmium toxicity may be due to differences in the life cycle stage (juvenile-adult), moult cycle stage, reproductive period or gender of the organism (McCahon and Pascoe 1988a, b, c;Sornom et al 2010). Differences in other experimental conditions such as, temperature, salinity (Wright and Frain 1981;Martin and Holdich 1986;Roast et al 2001) and preexposure to other toxicants (Howell 1985;Stuhlbacher and Maltby 1992) could also explain the differences observed in LC 50 values.…”

Amphipods play an important role in many aquatic ecosystems and are commonly used in ecotoxicology and ecosystem health assessment. Several alien gammarids have been introduced in many regions of the world during the last decades. In this study, we investigated if differences in cadmium sensitivity occurred between (1) different species belonging to the family Gammaridae and (2) different populations of the same species originating from a polluted or a non-polluted site. The acute cadmium toxicity to two indigenous (Gammarus pulex and Gammarus fossarum) and four alien (Dikerogammarus villosus, Echinogammarus berilloni, Gammarus roeseli and Gammarus tigrinus) gammarids occurring in Belgium was tested. Significant differences (P < 0.05) in median lethal concentrations (LC(50)) were found between the different species, with 72 h-LC50s ranging from 6.3 to 268 μg/l and 96 h-LC50s from 4.7 to 88.9 μg/l. No clear trend in Cd sensitivity was found when comparing indigenous and alien gammarids. D. villosus, an alien invasive species, was the most sensitive to Cd toxicity and E. berilloni, another alien species, the least sensitive. In addition, larger Gammarid species were more sensitive to Cd toxicity than smaller ones. No significant differences were found between populations of the same species originating from metal polluted sites or non-polluted sites. Overall, our results showed that considerable differences in Cd sensitivity exist between gammarid species, which should be taken into consideration in environmental risk assessment and water quality standard setting. Finally, our data suggest that alien gammarids would not have an advantage over indigenous gammarids in Cd contaminated environments.

“…Sroda and Cossu-Leguille (2011b) demonstrated that females of G. roeseli and Dikerogammarus villosus were more sensitive to copper than respective males, the converse of our results with cadmium. G. roeseli submitted to a salinity stress revealed a significant higher sensitivity of females in survival, ventilation and ionoregulation (Sornom et al 2010). When authors have reported a lower mortality of females in comparison to males (Emery 1970;Benoit et al 1976;Heit and Fingerman 1977, our study), the tested substances were always a non-essential molecule (e.g.…”

Acanthocephalan parasites: help or burden in gammarid amphipods exposed to cadmium?

“…Gammarids are known to be sensitive to pollutants and can easily be used in laboratory and field studies (Kunz et al, 2010). Hence, many ecotoxicological studies have been carried out using gammarids to evaluate impacts of xenobiotics (Leroy et al, 2010;Sornom et al, 2010Sornom et al, , 2012Gismondi et al, 2012aGismondi et al, , 2013Vellinger et al, 2012). However, to our knowledge, no study has been devoted to PBDEs effects on Gammarus sp., although this specie offers advantages (e.g.…”

a b s t r a c tPolybrominated diphenyl ethers (PBDEs) are abundant in aquatic environment. However, only few studies have investigated their impacts on freshwater invertebrates. This work aimed to study the effects of BDE-47 and BDE-99 congeners on the chitobiase and chitinolytic enzymes activities of the freshwater amphipod Gammarus pulex, according to gender, PBDE concentration and time of exposure. In addition, the bioaccumulation of BDE-47 and BDE-99 were measured. Results revealed that females have bioaccumulated more PBDE than males, and BDE-99 was more accumulated than BDE-47. PBDE exposures for 96 h have caused chitobiase and chitinolytic enzymes inhibition. This study not only indicate the importance of taking into account various confounding factors (gender, congeners, concentration) to understand PBDE effects, but underline also disruptions of molting enzymes activities. These disturbances suggest effects on the gammarid development and reproduction, and consequently effects on the gammarid population, and on a larger scale, a dysfunction of the ecosystem.
