“…This ameliorating effect of chloride has been previously found in the amphipod Gammarus sp., in which an artificial supplement of chloride (70 ppm Cl -) reduced its mortality, and in the dipteran Chironomus sp., in which chloride reduced the adverse effects of nitrite on the development of its anal papillae (Glass 1996;Kelso et al 1999;Neumann et al 2001). The Cl -/NO 2 -competition system is believed to be operational in Gammarus sp., and in the case of Chironomus sp.…”

“…Similarly, it has been found that sodium and potassium can reduce ammonia toxicity to some aquatic invertebrates (Borgmann and Borgmann 1997;Beketov 2002). However, there is scarce knowledge on the toxic effects of nitrite to wild freshwater invertebrates and their interaction with chloride ions (Glass 1996;Kelso et al 1999;Neumann et al 2001;Alonso and Camargo 2006a). Furthermore, the ameliorating effect of chloride on nitrite toxicity to freshwater invertebrates, lacking specific respiratory structures and pigments (e.g., planarians), has been amply ignored.…”

“…Aquatic animals can take nitrite up from water through their chloride cells, located in the gills (fish and crustaceans) and in the anal papillae (Chironomus larvae, Diptera) (Lewis and Morris 1986;Alcaraz and Espina 1994;Jensen 1995;Neumann et al 2001). The rate of chloride active uptake is hindered by high external nitrite concentrations, because NO 2 -exhibits high affinity for the Cl -uptake mechanism (Jensen 1995(Jensen , 2003.…”

High nitrite concentrations in freshwater ecosystems may cause toxicity to aquatic animals. These living organisms can take nitrite up from water through their chloride cells, subsequently suffering oxidation of their respiratory pigments (hemoglobin, hemocyanin). Because NO 2 -and Cl -ions compete for the same active transport site, elevated chloride concentrations in the aquatic environment have the potential of reducing nitrite toxicity. Although this ameliorating effect is well documented in fish, it has been largely ignored in wild freshwater invertebrates. The aim of this study was to compare the ameliorating effect of chloride on nitrite toxicity to two species of freshwater invertebrates differing in physiology: Eulimnogammarus toletanus (amphipods) and Polycelis felina (planarians). The former species presents gills (with chloride cells) and respiratory pigments, whereas in the latter species these are absent. Test animals were exposed in triplicate for 168 h to a single nitrite concentration (5 ppm NO 2 -N for E. toletanus and 100 ppm NO 2 -N for P. felina) at four different environmental chloride concentrations (27.8, 58.3, 85.3, and 108.0 ppm Cl -). The number of dead animals and the number of affected individuals (i.e., number of dead plus inactive invertebrates) were monitored every day. LT 50 (lethal time) and ET 50 (effective time) were estimated for each species and each chloride concentration. LT 50 and ET 50 values increased with increases in the environmental chloride concentration, mainly in amphipods. Results clearly show that the ameliorating effect of chloride on nitrite toxicity was more significant in amphipods than in planarians, likely because of the absence of gills (with chloride cells) and respiratory pigments in P. felina. Additionally, this comparative study indicates that the ecological risk assessment of nitrite in freshwater ecosystems should take into account not only the most sensitive and key species in the communities, but also chloride levels in the aquatic environment.

“…The amount of rain during the warm summer months with increased evaporation, determines the concentrations of ions, like nitrite, in the shallow puddles and ditches. High salinity and high nitrite concentrations impact larval development in C. riparius/piger (Haas & Strenzke, 1957;Neumann et al, 2001). As the summer is also the time of highest larval abundance (Tokeshi, 1995), this coincidence provides thus potentially a functional mechanism for the observed pattern.…”

Experimental evidence for niche segregation in a sister species pair of non-biting midges

et al. 2012

The principle of limiting similarity states that closely related species need to partition resources of the habitat in order to coexist in the same general area. We tested this hypothesis experimentally with a sister species pair of non-biting midges (Chironomus riparius and C. piger) by assessing their relative larval fitness under several concentrations of nitrite and temperature regimes, as suggested by the observed habitat segregation in a previous field study. Both chironomid species often occur in eutrophic habitats like agricultural areas or industrial point source effluents. Based on field observations, we hypothesised C. piger to tolerate higher nitrite concentrations, higher temperatures and larger temperature ranges than C. riparius. As predicted, C. piger coped better with higher nitrite concentrations. Against the expectations, C. riparius had a tendentially higher fitness at both higher constant temperatures and larger daily temperature ranges. However, the interaction of both stressors favoured C. piger in warm high-nitrite habitats thus concurring to the field observations. The complex interaction of candidate environmental factors with antagonistic effects found here emphasises thus the necessity to experimentally assess field observations of niche segregation.

“…NO 2 -is toxic and adversely affects aquatic organisms at relatively low concentrations. For example, certain groups of sediment-dwelling invertebrates are harmed by NO 2 -concentrations between 10 and 20 µM (Neumann et al 2001, Kelso et al 1999b, and European Union guidelines recommend NO 2 -concentrations below 0.25 µM in waters that support salmonid fishes (European Economic Community 1978). N 2 O oxide, on the other hand, is an aggressive greenhouse gas with a warming potential 200 to 300 times greater than CO 2 ABSTRACT: The dynamics of the nitrogen intermediates N 2 O and NO 2 -in estuarine sediments were studied along a salinity gradient in the eutrophied Weser Estuary (Germany) using microsensors for N 2 O, NO 2 -, NO x -, and O 2 .…”
