In a series of other projects within the fields of atmospheric sciences, plant and soil sciences, ecology/zoology, 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. 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. 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). Past plant physiology-related isotope work, for example, seeked 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.
