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 r

Direct evidence of ancient human occupation is typically established through archaeological excavation. Excavations are costly and destructive, and practically impossible in some lake and wetland environments. We present here an alternative approach,

Oxygen isotope (δ18O) measurements on the exoskeletons of aquatic insects can be used to reconstruct changes in the δ18O of ambient water and, indirectly, to infer the climate and environmental conditions at the time of tissue synthesis. Prior to s

Publikováno v: Morlock, Marina A.; Wooller, M. J.; van Hardenbroek, Maarten Reinier; Schilder, Johannes Cornelis; Szidat, Sönke; Heiri, Oliver (2017). Seasonality of cladoceran and bryozoan resting stage δ13C values and implications for their use as palaeolimnological indicators of lacustrine carbon cycle dynamics.

The stable carbon isotope composition, expressed as δ13C values, of chitinous resting stages of planktivorous invertebrates can provide information on past changes in carbon cycling in lakes. For example, the δ13C values of cladoceran ephippia and
