Material cycles and ecosystem processes

Effects of disturbance events (insect mass reproduction, droughts, vegetation fires), climate change (warming, drying), land-use changes (forest conversion, land-use intensity) and biodiversity on material cycles, functions and dynamics of dissolved and particulate organic matter (DOM and POM) and ecosystem processes
