“…Throughout the world, aquatic invertebrates such as amphipods are used as bioindicator species for marine, estuarine, and freshwater biomonitoring programs by surveying field populations [2]. Laboratory toxicity tests and in situ bioassays with amphipods are also used to assess the toxicity of natural and spiked sediments [3][4][5], waters [6][7][8][9][10][11][12], and effluents [13][14][15].…”

Among freshwater invertebrates, Gammarus fossarum is an important test organism and is currently used in ecotoxicology for acute and chronic assays; nevertheless, reproductive toxicity test methods are not yet available for these species. In the present study, the reproductive cycle in Gammarus fossarum was characterized in order to propose a reproductive toxicity test encompassing molting, follicle growth, and embryonic development that will provide a better understanding of the mode of action of chemicals disrupting these hormone-regulated processes. A detailed description of the reproductive cycle in Gammarus fossarum was obtained. As in some amphipods, molt and reproductive cycles of G. fossarum females occur concurrently, lasting 30 d at 12°C. Each molt stage is characterized by a specific marsupial embryonic development stage and the size of developing follicles visible on the ovarian membrane. Based on these results, a 21-d reproductive toxicity test is proposed for this species. This new bioassay was applied to identify the specific impact of different stressors: cadmium, methomyl, nonylphenol, and a starvation diet. Good reproducibility was obtained for different endpoints under control conditions and throughout the experiments. Preliminary robust reference values or benchmarks were proposed for these endpoints. Cadmium was found to specially inhibit secondary vitellogenesis. Nonylphenol had a specific concentration-dependent effect on embryonic development, with an increase in the percent abnormality from a concentration of 0.05 µg/L. A restricted food diet led to a significant delay in the molt cycle, which in turn induced inhibition of secondary vitellogenesis.

“…Many studies have explored the impacts of heavy metals on this organism (Wu and Chen 2005;Pestana et al 2007;Fialkowski et al 2009). Generally, earlier studies have focused on the effects of environmental pollution or an external source of heavy metals.…”

This study was conducted to determine the single and combined effects of cadmium (Cd) exposure at different concentrations and durations on biological responses in Gammarus pulex. The animals were exposed to 4, 8, 16 or 32 lg l -1 of CdCl 2 for 24, 48, 72 or 96 h, respectively. Cd accumulation, protein content, malondialdehyde content (MDA) and three antioxidant enzymes superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) were studied. The results were analyzed with two-way analysis of variance (two-way ANOVA) to assess the significance of the effects of exposure concentration and duration and their combined effects. The highest accumulation of Cd was found as 15.07 lg g -1 at 32 lg l -1 and 96-h Cd exposure. There was a significant correlation between accumulated Cd concentration and MDA and protein content and GPx activity. Although there was no significant synergistic effect of duration and concentration on Cd accumulation, a significant synergy of duration and concentration was observed in all other studied parameters. Interestingly, with the exception of GPx activity, the effect of concentration was greater than the effect of duration for all studied parameters. GPx activity showed that duration had a greater effect than concentration. Additionally, both SOD and GPx are more effective than CAT during Cd stress. The results of this study may be useful for understanding the relationship between organisms and environmental toxins.

“…In the case of aquatic arthropods, the effect of molting on accumulated concentrations may be crucial (e.g., Bergey and Weis, 2007), thus it is needed to select intermolt individuals, a procedure that may be labor-intensive, particularly when species exhibiting small size are used (e.g., talidrid amphipods used as metal monitors, Fialkowski et al, 2009, and literature quoted therein).…”
