“…These lakes covered a wide range in latitude and, consequently, also in lake water δ 18 O. Verbruggen et al (2011) showed that a correlation exists between expected δ 18 O in precipitation and δ 18 O of both chironomid and cladoceran remains deposited in these lakes. However, invertebrate δ 18 O was even more closely and linearly related to δ 18 O of lake water ( Figure 3A).…”

“…Their study confirmed that chironomid δ 18 O can provide insights into past changes in δ 18 O of precipitation, and, indirectly, on past climatic changes. Verbruggen et al (2011) examined the relationship between δ 18 O of chironomid and cladoceran remains, lake water, and expected precipitation for 31 lakes in Europe. These lakes covered a wide range in latitude and, consequently, also in lake water δ 18 O.…”

“…Therefore, any interpretation of fossil chironomid isotopic records, usually based on compound samples consisting of many chironomid head capsules, will have to take account of these processes and isotopic measurements based on fossil assemblages may only be comparable to a limited extent with measurements based on individual larvae collected in contemporary lake ecosystems. Calibration datasets based on lake surface sediment allow a direct comparison of isotopic measurements on selected sediment components with environmental parameters measured in contemporary aquatic ecosystems (e.g., water chemistry and the isotopic values of available food and water in lakes) (e.g., Herzschuh et al 2010;Verbruggen et al 2011;van Hardenbroek et al 2012a, b). Such datasets will be necessary for up-scaling measurements based on fossil chironomid remains to allow reconstructions of past environmental changes in lakes and their environment.…”

“…Since Wooller et al's (2004) pioneering work several additional studies focusing on stable isotopes in chironomid remains have been published (Wooller et al , 2012Wang et al 2008;Griffiths et al 2010;van Hardenbroek et al 2010van Hardenbroek et al , 2012aVerbruggen et al 2010aVerbruggen et al , 2011. It is expected that this approach will become more popular and widely applied once the initial methodology has been developed and the necessary calibration studies and calibration datasets have been produced.…”

. 2012. Stable isotopic analysis of fossil chironomids as an approach to environmental reconstruction: state of development and future challenges. Fauna norvegica 31: 7-18.Remains of chironomid larvae, especially their strongly sclerotized head capsules, can be found abundantly and well preserved in most lake sediment records. These remains mainly consist of chitin and proteins and, since their chemical composition does not seem to be strongly affected by decompositional processes, they can be used to develop palaeoenvironmental reconstructions based on their stable isotopic composition. Here we review available stable isotope studies based on fossil chironomids and indicate future research necessary to further develop this still relatively new research approach. Efforts to produce stable isotope records based on fossil chironomids have mainly examined the elements H, N, C, and O. They have focussed on (1) developing the methodology for preparing samples for isotopic analysis, (2) laboratory studies cultivating chironomid larvae under controlled conditions to determine the factors affecting their stable isotopic composition, (3) ecosystem-scale studies relating stable isotopic measurements of fossil chironomid assemblages to environmental conditions, and (4) developing first down-core records describing past changes in the stable isotopic composition of chironomid assemblages. These studies have shown that chemical sample pretreatment may affect the isotopic composition for some elements. Laboratory runs suggest that the diet of the larvae influences their stable isotopic composition for H, N, C and O, whereas stable isotopes in the ambient water also strongly influence their oxygen and to a lesser extent hydrogen isotopic composition. These experiments also indicate only minor offsets between the nitrogen and carbon isotopic composition of chironomid soft tissue and the fossilizing head capsules, whereas for hydrogen and oxygen this offset remains to be explored. Though few datasets have been published, the available ecosystem studies and developed down-core sediment records indicate that stable isotopes in chironomid remains have the potential to provide reconstructions of past climatic change (H, O) and insights into past food web structure, methane production and pollution of lake ecosystems (N, C). Future efforts will be necessary to develop these approaches including more detailed analyses of the effects of sample pretreatment on stable isotope measurements on chitinous fossils, more extensive laboratory studies constraining the effects of external factors (e.g., isotopic composition of food and ambient water, temperature) on stable isotopes in chironomid larvae, and surveys exploring seasonal changes in the isotopic composition of chironomid larvae and assessing how this seasonality influences fossil assemblages. Finally, multi-site field studies relating chironomid δD, δ 15 N, δ 13 C and δ 18 O to parameters such as δ 18 O of precipitation, air and water temperatures, and nutrient and greenhouse gas conc...

“…The δ 15 N values of chironomid head capsules and of Daphnia resting eggs (ephippia) have also been examined to investigate changes in nitrogen sources in an arctic lake (Griffiths et al, 2010). Past variations in lake water δ 18 O values have been reconstructed by analyzing the δ 18 O values of fossil chironomid head capsules (Wooller et al, 2004;Verbruggen et al, 2010b), and a correspondence has been found between δ 18 O values of lake water and of chironomid head capsules and Daphnia ephippia buried in surface sediments (Verbruggen et al, 2011).…”

Abstract. The stable isotopic composition of fossil resting eggs (ephippia) of Daphnia spp. is being used to reconstruct past environmental conditions in lake ecosystems. However, the underlying assumption that the stable isotopic composition of the ephippia reflects the stable isotopic composition of the parent Daphnia, of their diet and of the environmental water have yet to be confirmed in a controlled experimental setting. We performed experiments with Daphnia pulicaria cultures, which included a control treatment conducted at 12 • C in filtered lake water and with a diet of fresh algae and three treatments in which we manipulated the stable carbon isotopic composition (δ 13 C value) of the algae, stable oxygen isotopic composition (δ 18 O value) of the water and the water temperature, respectively. The stable nitrogen isotopic composition (δ 15 N value) of the algae was similar for all treatments. At 12 • C, differences in algal δ 13 C values and in δ 18 O values of water were reflected in those of Daphnia. The differences between ephippia and Daphnia stable isotope ratios were similar in the different treatments (δ 13 C: +0.2 ± 0.4 ‰ (standard deviation); δ 15 N: −1.6 ± 0.4 ‰; δ 18 O: −0.9 ± 0.4 ‰), indicating that changes in dietary δ 13 C values and in δ 18 O values of water are passed on to these fossilizing structures. A higher water temperature (20 • C) resulted in lower δ 13 C values in Daphnia and ephippia than in the other treatments with the same food source and in a minor change in the difference between δ 13 C values of ephippia and Daphnia (to −1.3 ± 0.3 ‰). This may have been due to microbial processes or increased algal respiration rates in the experimental containers, which may not affect Daphnia in natural environments. There was no significant difference in the offset between δ 18 O and δ 15 N values of ephippia and Daphnia between the 12 and 20 • C treatments, but the δ 18 O values of Daphnia and ephippia were on average 1.2 ‰ lower at 20 • C than at 12 • C. We conclude that the stable isotopic composition of Daphnia ephippia provides information on that of the parent Daphnia and of the food and water they were exposed to, with small offsets between Daphnia and ephippia relative to variations in Daphnia stable isotopic composition reported from downcore studies. However, our experiments also indicate that temperature may have a minor influence on the δ 13 C, δ 15 N and δ 18 O values of Daphnia body tissue and ephippia. This aspect deserves attention in further controlled experiments.
