“…This study confirms previous results obtained in the laboratory (Felten & Guerold 2001). Since the effect of acid stress on the ecophysiology of Gammarus fossarum was detectable at sublethal levels, it may be possible to use haemolymph [Na + ] and [Cl -] to monitor acidification pollution (Handy & Depledge 1999, Lignot et al 2000.…”

“…Gammarus fossarum (Crustacea: Amphipoda) because this species presents several interesting characteristics for ecotoxicological investigations: it is (1) an acidsensitive species (Guerold et al 2000, Felten & Guerold 2001, (2) widespread and common in Paleartica (Barnard & Barnard 1983), (3) often occurs in high density, (4) easy to identify to species level, (5) characterised by sexual dimorphism and (6) plays a major role in the leaf breakdown process and consequently in the entire food web (Pöckl 1995).…”

“…In a previous laboratory study (Felten & Guerold 2001), we showed that Gammarus fossarum (Crustacea: Amphipoda), a common acidsensitive species in west Palearctica, also sustained a severe depletion of haemolymph Na + and Cl -ions when exposed to realistic acidic conditions.…”

Plecoptera response to acidification in several headwater streams in the Vosges Mountains (northeastern France)

Plecoptera are among the most threatened aquatic invertebrates in industrialised countries as they are very sensitive to many types of pollution. On the contrary, stoneflies are largely considered as tolerant to acidification in comparison with many other macroinvertebrate groups. However, an understanding of Plecoptera responses to acidification is lacking due firstly to the complexity of most Nemouroidea specific determinations at larval instars and secondly to the poor Plecoptera diversity in North European countries, where most studies on acidification impact were performed. In the present study, we assess the response of Plecoptera species and species assemblages to freshwater acidification by collecting adults, allowing specific determination. Significant relationships were observed between richness and several chemical parameters. The relative abundance of several species was also significantly correlated to pH and acid neutralizing capacity (ANC). The results highlight the importance of species determination to assess the effects of acidification. Direct effects, i.e. ecotoxicological effects, were not the only factor leading to the erosion of Plecoptera diversity. Finally, this study tends to demonstrate that this order of aquatic insects is more severely affected by freshwater acidification than commonly believed.

“…Amphipods, as a taxonomic group, are reputed to be one of the most acid-sensitive aquatic macroinvertebrates (e.g. Sutcliffe & Carrick, 1973;Guerold et al, 2000;Felten & Guerold, 2001). This has been shown to be due to respiratory and ion-regulatory failure (Felten & Guerold, 2001), probably in addition to possessing a calcified exoskeleton.…”

Macroinvertebrate cycles of decline and recovery in Swan Coastal Plain (Western Australia) wetlands affected by drought-induced acidification

Management of wetlands influenced by the Gnangara groundwater mound, Western Australia, is becoming increasingly challenging due to an ongoing decline in the regional groundwater table. A number of these groundwater-dependent wetlands have acidified (with adverse effects on the extant macroinvertebrate fauna) due to the oxidation of pyritic sediments. One management option in such cases is artificial augmentation of surface water in order to maintain or reinstate anaerobia in the sediments. This paper documents cycles of macroinvertebrate decline and recovery over 12 years of monitoring in three Gnangara mound wetlands affected by drought-induced acidification, one of which is being artificially augmented. Acidification did not result in a reduction of the total number of macroinvertebrate families present, however, there were clearly identifiable groups of acid-sensitive taxa (amphipods and isopods, ostracods, chydorid and daphnid cladocerans, mayflies, oligochaetes, clams and snails) and acid-tolerant taxa (sandfly larvae, macrothricid cladocerans and water boatmen). In the artificially augmented wetland, the effects of acidification were reversed: acid-sensitive taxa reappeared and acid-tolerant taxa decreased in numbers.Moreover, there were a number of taxa that appeared for the first time since augmentation, and summer family richness increased markedly. This study has shown that artificial augmentation of wetland water levels can be a successful recovery strategy for recently acidified systems, but this will depend on a number of factors, and the 'recovered' state will be at least slightly different from the original state.
