“…We additionally conducted life-cycle tests with a nominal Cd-concentration of 1.2 mg Cd/kg sediment dw over three subsequent generations. Cd was selected because several studies already indicated the toxicity for chironomid larvae at the chosen concentration range (Watts and Pascoe 2000;Milani et al 2003;Vogt et al 2007a).…”

“…sediments in the laboratory. The main advantages of chironomids as test species are that they (1) are easy and cheap to culture in the laboratory; (2) spend a large part of their life-cycle as a larva in the sediment; (3) are model organisms for a widespread and species-rich taxonomic order in aquatic ecosystems; (4) are sensitive to pollutants; (5) have a short life-cycle with completing ten or more generations per year under standard conditions and (6) perform sexual reproduction (Benoit et al 1997;Vogt et al 2007a). Furthermore, two guidelines were developed for the routine testing and assessment of chemicals, wherein the larvae were exposed to substances via sediment (OECD 2004a) or via water (OECD 2004b).…”

So far only a few studies have been performed to assess the effects of dynamic pollutant exposure on life-history parameters of invertebrates. In a previous multi-generation approach with the midge Chironomus riparius we tested if a chronic tributyltin pre-exposure alters the ability of a population to cope with subsequent cadmium stress. In the experiment two separate chironomid populations were exposed via sediments to different TBT-concentrations (4.46 and 8.93 μg Sn/kg dw) for several generations, followed by subsequent cadmium exposure (1.2 mg Cd/kg dw) for three generations. While the TBT-exposure to 4.46 μg Sn/kg dw had only small effects on the development and reproduction of C. riparius the higher TBT-concentration of 8.93 μg Sn/kg dw led to negative effects on life-history traits. Therefore, a higher adverse effect of the higher TBT-concentration and thus a higher susceptibility to other stressors could be assumed. Within, this paper only the results of the second stressor experiment were presented; clear effects of Cd on development and reproduction of C. riparius were determined independent of the pre-exposure scenario. While no differences in Cd-sensitivity were found between the population without pre-exposure to TBT and the population pre-exposed to the low TBT-concentration (4.46 μg Sn/kg dw), the pre-exposure of midges to the higher TBT-concentration (8.93 μg Sn/kg dw) resulted in a significantly higher susceptibility to subsequent Cd-stress. These results document that the exposure history may influence the reaction to altered chemical stress. Our findings are relevant to understand and predict the evolutionary fate of populations in rapidly changing, human-impacted environments. However, the fact that chemical-induced reduced genetic diversity, which is not necessarily linked to genetic adaptation, leads to a reduced fitness under altered stress conditions, is to our knowledge a novel finding.

The genetic diversity of natural populations and the increase in global temperature are becoming important issues in ecotoxicological research. We investigated the combined effects of 3 different temperature levels and 6 different levels of genetic diversity on the life history parameters of Chironomus riparius. Inbreeding and loss of genetic variation are major threats to small and endangered populations. The reduction of fitness due to inbreeding is more severe under stressful environmental conditions. We show that under even a moderate temperature stress, a decrease in genetic variation has important consequences on the fitness of populations. This indicates that the global temperature increase could have serious effects on the distribution and survival of locally distributed or rare species.KEY WORDS: Life-history parameters · Microsatellites · Diptera · Chironomidae · Genetic impoverishment Resale or republication not permitted without written consent of the publisherClim Res 33: [207][208][209][210][211][212][213][214] 2007 The aim of this study was to determine the interaction between temperature stress and inbreeding, using an ectothermic aquatic invertebrate to test if genetically impoverished populations exhibit a higher sensitivity to temperature shifts. We selected a species from the dipterian family of Chironomidae, the non-biting midge Chironomus riparius, representing a model organism with a benthic-associated life cycle. Chironomids are widely distributed in the temperate northern hemisphere and are characterised by a huge ecological tolerance (Armitage et al. 1995). They can be found in hot springs, eutrophic and oligotrophic ponds, lowland rivers, and sub-glacial streams (Pinder 1986). Chironomids have 3 aquatic juvenile (egg, larvae and pupae) and one aerial adult life-stages (Olivier 1971). Previous studies assessing the effect of temperature variation (12-37°C) on chironomid growth patterns concluded that growth was promoted by increasing temperature up to a certain limit (Sankarperumal & Pandian 1991, Stevens 1998, Frouz et al. 2002, Pery & Garric 2006. In contrast, female body size and fecundity decreased with higher temperatures (Frouz et al. 2002, Gong et al. 2002. These studies were all performed with single populations; the additional impact of genetic diversity in connection with the effects of temperature shifts was not investigated. Hence, we tested if the development and reproduction of Chironomus riparius are affected by temperature shifts (± 3°C) and if there is an interaction between these effects and genetic diversity. MATERIALS AND METHODS Test organismsFor the experiments, 6 different Chironomus riparius populations were used (Table 1). One population, with a high inbreeding level (Pop. VI) was obtained from ECT Ecotoxicology, Flörsheim. Five other genetically different populations (Pop. I-V) were derived from different generations of a multi-generation study (under controlled conditions) performed using our inbred inhouse mass culture (GEN-) and a genetically ...

“…Several reported physiological effects on invertebrates, such as Dog-whelks (Nucella lapillus) and sea snails (Thais clavigera) exist at environmental conditions of a few ng/l (Gibbs and Bryan 1986;Horiguchi et al 1997), as well as effects, especially on the immune defence system, of fish and seals (Allner et al 2010;Frouin et al 2008). The effects of organic tin compounds on benthic insects and their larvae, such as chironomids (Diptera: Chironomidae) have been studied less (Nowak et al 2009;Vogt et al 2010;Vogt et al 2007b;Vogt et al 2007a) and should be a target of further research due to their paramount importance as food for, e.g., several fish and bird species (Coffman and Ferrington 1996;Looser et al 2000).…”

Sediment organic tin contamination promotes impoverishment of non-biting midge species communities in the Archipelago Sea, S-W Finland

Chironomid species are a vital component in many benthic and terrestrial food webs; they have an important role in the detritus cycle, and are an important source of food for many species. We studied how tributyltin (TBT) in brackish water sediments affect the composition of chironomid species communities. Emergence traps were used at selected sites on a TBT gradient in the Archipelago Sea, S-W Finland. Increased sediment TBT concentration was associated with significant chironomid species turnover, which in turn was related to decreased species diversity (number of species and genera). However, the overall number of individuals did not decrease markedly with increasing TBT contamination. This suggests that the ecological role of chironomids in the food web may be preserved even under severe impoverishment of the chironomid community due to organic tin contamination. The increased prevalence of more TBT tolerant species can potentially lead to a transport of organic tin compounds between aquatic and terrestrial food webs. Furthermore, the reduced diversity of an ecologically influential group might lower the resistance of the entire food web to other environmental hazards and perturbations.
