2 Environmental controls on fluxes and processes in ecosystems

Dienstag, 12:10 - Donnerstag, 16:30, H18

Element cycling in (semi-) natural landscapes is affected by a wide range of interacting environmental factors including climate, deposition and land use. Some drivers (deposition, atmospheric CO2, temperature, precipitation) may exert a long-term, chronic control on biogeochemical cycles while others (extreme events, natural and anthropogenic disturbances) may be more abrupt. In this session, we welcome studies that address specific environmental controls on ecosystem fluxes and processes in vegetation, soils and surface waters. We encourage novel contributions from process-oriented studies, but also experimental manipulations preferably at the landscape- or plot scale.
