Description
1-Documentation and characterisation of biodiversity loss and the degradation of ecosystemic services. This part should provide data to characterize the amplitude and the spacio-temporal changes in biodiversity at different levels: extinction/speciation, community organisation and dynamics of functional groups. 2-Describe and model the changes in biodiversity. The main goals are to find the parameters that trigger the changes in biodiversity and to model the functioning of the systems under changes to predict their evolution. 3- Understand the dynamic interaction between economical and social processes and the reduction of the biodiversity. Data are expected here to increase the knowledge about processes and the responses of human societies to these processes.
