Alexandra-Maria Klein

Alexandra-Maria Klein (born September 17, 1972 in Göttingen ) is a German biologist and professor of nature conservation and landscape ecology at the University of Freiburg .

life and career

Klein studied biology at the University of Göttingen from 1993 to 2000 and completed his diploma. In 2003 she did her doctorate there with Teja Tscharntke in agroecology and zoology . From 2007 to 2008 she was a visiting scholar in Claire Kremen's group at UC Berkeley (California) , funded by the Alexander von Humboldt Foundation . In 2010 she qualified as a professor at the Faculty of Agricultural Sciences at the University of Göttingen. In April 2010, Klein became professor for ecosystem functions at the Institute for Ecology at Leuphana University Lüneburg , and from 2011 she headed the institute. In June 2013 she became professor for nature conservation and landscape ecology at the University of Freiburg im Breisgau.

Klein's main interest is the ecology of plant-insect interactions such as B. Pollination in cultivated landscapes . Her focus is on bees and their ecosystem functions and services. Using a functionalist approach, she investigates the stability of ecosystems and the effects of landscape changes on plants and insects.

For the WDR consumer magazine markt, she calculated that the failure of bees to pollinate cultivated plants in Germany would result in costs of 1.3 billion euros.

In 2016 Alexandra-Maria Klein took part as protagonist in the zdf documentary "Ausgebrummt - Insect dieback in Germany" by Andreas Ewels and Norbert Porta from ScienceDoku in Planet Earth. This year she also contributed to the zdf documentation with Harald Lesch and Dirk Steffens "Noah's Ark 2017 - The Long Night of Species Protection". As for the evening news and now given on the impact of insects Serbens interviews. For example, Klein made radio contributions for Detector fm.

Projects and Awards

Klein's working group was involved in the Jena Experiment (DFG 2010-2013) and examined plant-insect interactions, flower characteristics and pollination along an experimental plant diversity gradient as well as above-ground plant-insect interaction networks and associated processes along a plant diversity gradient (with Christoph Scherber).

In cooperation with Bayer CropScience , she is researching until 2014 in the program Global evaluation of bee attractiveness and apicultural relevance of agricultural crops and together with Teja Tscharntke on the ecological evaluation of crop pollination in traditional house gardens in Indonesia (DFG project 2012-2015) . The “Leuphana Research Platform for Sustainable Biokerosene Production” in Lüneburg was about the possibly sustainable production of biofuel. Here she worked together with the economist Stefan Schaltegger . In China she is in charge of the project on above-ground multi-trophic plant-insect interactions in a Chinese subtropical forest with Nico Blüthgen in the DFG research group "BEF China" (DFG 2011–2016). Since 2015 she has been coordinating an EU biodiversa project "EcoFruit" with partners from Spain (e.g. Jordi Bosch) and Sweden (e.g. Peter Hambäck). Further completed and ongoing projects and graduate schools can be found on the homepage of the Professorship for Nature Conservation and Landscape Ecology at the University of Freiburg. Klein deals with basic research and less with questions of normative, applied nature conservation.

For her field work in California in 2009, she received the Alexander von Humboldt Research Prize for Field Work in California. In 2012, her work was selected for the Ecological Society of America's Program Enhancement Fund .

In 2013 Klein was elected for the subject “Ecology of Agricultural Landscapes” in the Expert Committee of Agricultural, Forestry and Veterinary Medicine of the German Research Foundation (DFG) and was re-elected in 2016.

In 2014, Alexandra-Maria Klein was awarded the CULTURA Prize from the Alfred Toepfer Foundation for her research into the effects of landscape changes on bees and other pollinators . Furthermore, in 2014 Klein was appointed lead author of the World Biodiversity Council IPBES for the work program “Pollinators, Pollination and Food Production”. Alexandra-Maria Klein was also appointed to the European Academies Science Advisory Council (EASAC) for the expert group “Ecosystem Services, Agriculture and Neonicotinoids” by the Leopoldina National Academy of Science. In addition, she became a member of the Management Committee of the EU COST Action FA1307: SUPER-B: Sustainable Pollination in Europe: joint Research on bees and others and appointed as a deputy member of the expert committee for nature conservation issues of the Ministry for the Environment, Climate Protection and Energy in Baden-Württemberg.

Since 2015, Klein has been Vice President of the Society for Ecology for Germany, Switzerland and Austria (GFÖ) and a member of the Senate Commission for Agro-Ecosystem Research of the German Research Foundation (DFG)
