“…Our results support previous findings that cladocerans are one of the most sensitive taxon and toxicity data based on cladocerans are likely protective to copepods and other freshwater organisms (Wogram and Liess 2001;Brix et al 2005). Knowledge on the mechanisms responsible for the differences in metal sensitivity among aquatic invertebrates is incomplete, but microcrustaceans, including copepods and cladocerans, seem to use similar pathways to detoxify trace metals.…”

“…Yet its key assumptions such as species being randomly sampled and representing the natural biological assemblage are questionable (Forbes and Calow 2002; Leung et al 2005). For instance, the over-representation of cladocerans in toxicity datasets for freshwater organisms (Brix et al 2005) brings out the question whether these datasets can be protective to other aquatic organisms. Cladocerans, particularly Daphnia, are absent in some freshwater habitats, yet they are still included in the datasets in deriving WQC (Brix et al 2005).…”

Toxicity data based on cladocerans can be used to represent freshwater crustacean zooplankton in the establishment of WQC only if the sensitivity of cladocerans to toxicants is comparable to or higher than that of copepods.…”

Cladocerans and copepods are common inhabitants of ponds and lakes, but assessments of the toxic effects of chemicals on aquatic organisms are often based mainly on toxicity data for cladocerans of the genus Daphnia. The paucity of toxicity data for copepods and other species of cladocerans raised the question whether toxicity data derived primarily from daphniids can be extrapolated to protect other planktonic organisms. In this study, we address this question by systematically comparing between the sensitivities of cladocerans and copepods to the metals Cd, Cu, Pb, Ni, and Zn using the species sensitivity distributions. Our results indicate that cladocerans are consistently more sensitive than copepods to Cd and Cu. Most importantly, sensitivities of D. magna, D. pulex, and Ceriodaphnia dubia, the three most commonly tested cladocerans, to these metals are higher than those of most copepod species and fall within the range of those exhibited by other cladocerans. C. dubia, a cladoceran with relatively small body size, is more sensitive to all metals than most other cladoceran species. Our results imply that water quality criteria of trace metals derived from datasets dominated by Daphnia are likely also protective to copepods and most other cladocerans.

“…34,35 Because aquatic insects are poorly represented in the database used to establish these criteria, 12 there is the potential that these organisms will not be protected by current water quality standards. 5 Additionally, laboratory toxicity tests conducted with aquatic insects, particularly those using later instars, show much greater tolerance to metals compared to patterns observed in the field.…”

Identifying causal relationships between acid mine drainage (AMD) and ecological responses in the field is challenging. In addition to the direct toxicological effects of elevated metals and reduced pH, mining activities influence aquatic organisms indirectly through physical alterations of habitat. The primary goal of this research was to quantify the relative importance of physical (metal-oxide deposition) and chemical (elevated metal concentrations) stressors on benthic macroinvertebrate communities. Mesocosm experiments conducted with natural assemblages of benthic macroinvertebrates established concentration–response relationships between metals and community structure. Field experiments quantified effects of metal-oxide contaminated substrate and showed significant differences in sensitivity among taxa. To predict the recovery of dominant taxa in the field, we integrated our measures of metal tolerance and substrate tolerance with estimates of drift propensity obtained from the literature. Our estimates of recovery were consistent with patterns observed at downstream recovery sites in the NFCC, which were dominated by caddisflies and baetid mayflies. We conclude that mesocosm and small-scale field experiments, particularly those conducted with natural communities, provide an ecologically realistic complement to laboratory toxicity tests. These experiments also control for the confounding variables associated with field-based approaches, thereby supporting causal relationships between AMD stressors and responses.

“…However, without a means for deciding the temporal distribution of Cu concentration through the year, there is no reliable basis for applying a more sophisticated metal toxicity model. Nonetheless, the magnitude is sufficient to suggest that environmental harm is likely, falling as it does within a range of Cu concentrations demonstrated to be harmful (Brix et al 2005;Van Sprang et al 2008). For freshwater systems this is particularly critical, as in aqueous media plants are directly exposed to the harmful effects of Cu and, thus, algae and some species of aquatic higher plants are more easily subjected to Cu toxicity (Gupta 1986;Jana and Choudhuri 1982;Fernandes and Henriques 1991).…”
