For the Department of Ecosystem Research of IGB at the location Berlin-Adlershof we are inviting applications for the position of a doctoral researcher starting as of 01.03.2021 or when the position is filled.

Become part of the research group Aquatic Ecogeography – we are an international team investigating the impacts of global change on freshwater (particularly riverine) ecosystems. We combine hydrology, community ecology, conservation biology, ecological & habitat modelling, and biogeography approaches. The position will be embedded in the Collaborative Research Center 1439 RESIST (“Multilevel response to stressor increase and release in stream ecosystems”) which has been recommended for funding by the German Research Foundation (DFG). This project will develop species distribution models (SDMs) for selected diatom, invertebrate and fish species. It aims to advance previous species distribution modelling approaches by the involvement i) of stressor interactions, ii) life cycle related habitat use, and iii) asymmetric recovery patterns and to eventually integrate these into a model considering critical timing and importance of environmental conditions during different life stages and during phases of degradation and recovery.

Your tasks

  • Data acquisition and SDMs preparation for selected diatom, invertebrate and fish species
  • Develop a set of SDMs that reflect stressor interactions
  • Explore the consideration of life stage information in SDMs
  • Develop SDMs for different time periods, i.e. periods reflecting stressor increase and recovery

Your profile

  • Diploma or Master´s degree in a relevant subject with a sound background in environmental sciences (biology, ecology, limnology, bioinformatics or a related topic).
  • Essential is a strong interest in working with aquatic organisms (diatoms, aquatic invertebrates, fish).
  • Essential is the willingness to cooperate within RESIST and develop a close cooperation with hydrologists within the CRC.
  • Essential are very good verbal and written communication skills in English.
  • Desirable is experience in one or several of the following skills: handling large data sets, statistical analysis, ecological & habitat modelling (e.g. Biomod), use of R, GIS, preferably open source GIS (e.g. QGIS)

Our offer

We offer an interesting position in an international, interdisciplinary, and dynamic scientific environment. We encourage everyone to develop and use their creativity to the best of their abilities. The position will be embedded in the DFG-funded CRC RESIST program, creating a superb scientific network. RESIST is coordinated by the University of Duisburg-Essen with the participation of the Ruhr-University of Bochum, University of Cologne, Christian-Albrechts-Universität zu Kiel, the University of Koblenz-Landau, Helmholtz Centre for Environmental Research (UFZ) and IGB.
Salary is paid according to the German salary scheme for the public sector (TVöD Bund). It is a 65% position for doctoral research. It is a fixed-term position, limited to 3 years.

We foster your career development by providing qualification and training opportunities. We actively support the reconciliation of work and family life. Applicants are treated equally regardless of gender. Qualified women are particularly encouraged to apply. Applications of severely disabled persons with equal qualification will be given priority.

“Research for the future of our freshwaters” is the mission of the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB). The IGB is Germany’s largest and one of the leading international research centres for freshwaters. We seek to understand the fundamental processes governing freshwaters and their communities. Our research findings help to tackle global environmental changes and to develop measures for sustainable water management. The IGB is a diverse and inspiring place to work and conduct research. We promote individual development at every career level and stand for lively exchange and cooperation. With more than 350 employees and guests from all over the world, we conduct research at five locations in Berlin and at Lake Stechlin (Brandenburg). IGB closely collaborates with numerous national and international universities and other partners in science and society and is a member of the Leibniz Association, which connects 96 independent public research institutes in Germany.
