Isotope measurements on chitinous invertebrate remains

We study the stable carbon isotopic composition of aquatic invertebrate remains in lake sediment records to provide information on past changes in the 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 isotopic measurements on lacustrine invertebrate remains for reconstructing past changes in lacustrine foodwebs and past climate changes. This work was initiated by the ERC Starting Grant Project RECONMET (2010-2014).
