Other stable isotope research

In a series of other projects within the fields of plant and soil sciences, ecology/zoology, atmospheric sciences, and archaeology, and in collaboration with research groups within and outside the Department of Environmental Sciences, we apply stable isotope measurements to address a wide spectrum of various research questions. Ongoing plant physiology-related isotope work, for example, seeks to study nutrient and carbon exchange during symbiont-host interactions between plants and mycorrhizal networks, making use of isotope labelling techniques, and bulk and biomarker isotope measurements. Within the frame of archaeological projects, we aim at using stable isotope measurements of well-dated cattle and red deer bone samples from Swiss Neolithic lakeshore settlements for reconstructing Neolithic herding strategies (e.g., transhumance). In collaboration with atmospheric chemists, we perform aerosol and cloud N and O isotope measurements  (δ15N and δ18O of particulate NO3- and NH4-), to identify and quantify sources of nitrogeneous species (and formation processes) in the atmosphere.
