IPBES Assessment on the diverse conceptualization of multiple values of nature and its benefits

Prof. Stefanie Engel and Dr. Ann-Kathrin Koessler have been selected to contribute as Lead Author and Fellow, respectively, to the upcoming IPBES report 'Methodological assessment regarding the diverse conceptualization of multiple values of nature and its benefits'. IPBES, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, is a scientific, inter-governmental panel of the UN, which aims to provide objective and reliable information on the state and development of biodiversity and ecosystem services. The forthcoming report deals with the issue which methods and tools are suited for the assessment of the multiple values of biodiversity and ecosystem services. For more information on IPBES, see

Stefanie Engel became member of the new DFG Permanent Senate Commission on Fundamental Issues of Biological Diversity.

Bellman Prize for mathematical analysis of harvest timing

The 16th Bellman Prize goes to Frank Hilker, professor of Applied Systems Science, and his co-authors Begoña Cid und Eduardo Liz from the University of Vigo in Spain. The prize epitomizes the successful application of rigorous mathematics and computation to a highly pertinent biological phenomenon.
