Reconstruction of methane flux from lakes: development and application of a new approach (RECONMET)
Within the ERC Starting Grant Project RECONMET the stable carbon isotopic composition of aquatic invertebrate remains will be studied to provide information on past changes in the importance of methane as a carbon source for aquatic foodwebs. The project will study lake ecosystems in Switzerland, Finland, Germany, and Sweden to assess the extent to which the distinct carbon isotopic composition of methane can be traced in organic invertebrate remains from lakes with different methane concentrations and output. The aim is to develop carbon isotopic measurements on organic invertebrate remains as a new approach for reconstructing past changes in foodweb structure, methane availability, and methane fluxes in lakes.
