Biogeochemistry in forest and nature under change

The work in the research group can be described by the following keywords and key issues:

  • Biogeochemical cycles: We quantify fluxes (input, cycling processes, output) and storage of water, C, N, P and other elements in ecosystems.
     
  • Response to change: We estimate the responses of these fluxes, processes and stocks to environmental changes (climate, air pollution etc.) as well as changes in management and land use (afforestation/land use legacy, tree species, forest treatments, nature restoration, and management regimes).
     
  • Ecosystem functioning: We couple flux rates and processes with ecosystem soil and water properties, plant traits and presence and activities of key organisms to identify suitable indicators of functioning.
     
  • Soil processes and functioning: The role of soils is central in our studies. The major element pools in soils is a challenge for the quantification of change, but at the same time essential for understanding the feedback and functioning of the plant-soil system.
     
  • Element interactions: We investigate the interaction of the element cycles and the stoichiometric relationships in the plant–soil-atmosphere system.
     
  • Scale and extrapolation: We work at scales from molecule to ecosystem often with the prospect of extrapolating to landscape or national levels at timescales from hours to centuries (rotations).
     
  • Experimental basis: We preform long-term monitoring, large scale manipulation experiments and microcosm experiments related to natural ecosystems, and use the same methods to explore biogeochemical processes in Christmas tree cultures, short-rotation forestry as well as urban settings.
     
  • Ecosystem services: We use the data and understanding to quantify and extrapolate ecosystem service provisioning (e.g. biomass production, water protection, C-sequestration) under future scenarios to inform land managers, interest groups and environmental policy.
