Assessment of the impact of ozone on biodiversity in terrestrial ecosystems
Tropospheric ozone is considered as the most significant phytotoxic pollutant in the atmosphere. The project will provide a synthesis of current knowledge on the effects of ozone on biodiversity and ecosystem services. Modelling and mapping approaches are used to analyze the risk of current ozone exposure levels for the vegetation in Germany.
The project aims (1) to review and analyze the available literature on the impact of ozone on biodiversity in terrestrial ecosystems and (2) to assess current uncertainties in concentration-based and flux-based approaches in ozone risk assessments by use of modelling and mapping approaches.
The project is split into 4 major work packages:
The review summarizes information on the ozone sensitivity of 343 cultivars of crop species, of 298 herbaceous wild plant species, and of 164 woody species. More than 50% of the investigated species must be regarded as ozone sensitive, including many native species. There is evidence that ozone change flowering, seed production and plant community composition which indirectly lead to changes in soil processes and water cycling thus affecting ecosystem structure and function
