Isotope measurements on chitinous invertebrate remains
The stable isotopic composition of individual lake sediment components, particularly organic remains of invertebrates and algae, can provide information on past environmental conditions in and around lakes as well as on past changes in ecosystem processes within lake ecosystems. We study the stable carbon isotopic composition of organic remains in lake sediment records to provide information on the past importance of methane as a carbon source for aquatic foodwebs, and for reconstructing past changes in the carbon cycle of lakes. Furthermore, we also explore the potential of stable hydrogen, nitrogen and oxygen isotope measurements on lake sediment components for reconstructing past changes in lacustrine foodwebs and past climate change. This work was initiated by the ERC Starting Grant Project RECONMET (2010-2014).
