Objectives

  1. Determine the response of soil biodiversity to warming (+4°C) in topsoil and subsoil of undisturbed whole–soil profiles under 3 different ecosystem types.
  2. Understand how microbial growth and turnover affects SOM dynamics and nutrient availability under soil warming.
  3. Elucidate the relationship between soil biodiversity, plant responses and biogeochemical cycling.
  4. Develop scenarios, based on a coherent and plausible set of assumptions on key quantitative driving forces using model-based simulations to understand and predict soil biogeochemical response to global change across spatial and temporal scales.
  5. Give management recommendations for the adaptation of ecosystems to climate change.
