Postdoctoral researcher for modelling aquatic ecosystems of water reservoirs via Research Gate

Institute of Hydrobiology

České Budějovice, , CZ

The Institute of Hydrobiology (IHB; at the Biology Centre of the Czech Academy of Sciences in Ceske Budejovice, Czech Republic, is looking for a postdoc/scientist for a 2-year stay aiming at development of modelling systems for simulating hydrodynamics, biotic interactions and water quality in water reservoirs.

IHB is the main institution in the Czech Republic engaged in comprehensive research of freshwater man-made reservoirs and natural lakes. Limnological interactions are studied both in water bodies and their catchments. The institute performs research on different levels of interactions from the ecosystem, community, population, organismal, through cellular to molecular levels. The investigations combine regular long-term ecological research at several reservoir and lake systems, comparative and methodical studies and different scale experiments that allow examining the phenomena at different time and space scales. The Institute applies a holistic approach from elementary chemistry to high trophic levels and social effects on water systems. Special investigations going beyond the investigations of lakes and reservoirs involve ponds, running waters and other aquatic environment.

Project description: The successful candidate will be responsible for developing and application of models for simulating the aquatic ecosystem in deep stratified reservoirs with the purpose to analyse:

  • Effects of hydrodynamics,  such as mixing  of the water column and stratified flows, on nutrient loading into the production layer and consequences for phytoplankton growth
  • Biotic interactions in the planktonic and fish communities,  i.e. the trophic cascade phytoplankton – zooplankton – fish
  • Responses of the reservoir ecosystem within the existing long-term historical data sets of hydrology, reservoir operation, water quality and biota and in scenarios of future climate and socio-economic conditions in the catchment

The candidate will be involved in the ongoing projects of IHB, such as ClimeFish (H2020-EU3.2, No.  677039; and Biomanipulation as a tool for the improvement of reservoir water quality and MEMOBIC (EU Operational Programme Research, Development and Education  Nos CZ.02.1.01/0.0/0.0/16_025/0007417 and CZ.02.2.69/0.0/0.0/16_027/0008357, respectively).

Qualifications required: For this position the candidate must hold a PhD degree in Limnology, Oceanography, Geochemistry, Civil Engineering, Environmental Science or a related subject. We are looking for a person with proficiency in using statistical methods and mathematical models to analyse environmental data; programming skills are desirable. Candidates must be fluent in spoken as well as written English. We put great emphasis on personal suitability as cooperation, independence and a constructive approach. The required condition is that the candidate has worked in the field of research outside the Czech Republic for at least 2 years during the last 3 years.

Position: This is a fulltime temporary position for 24 months with annual gross salary 29.000 € and expected start in May 2018. If successful, the employment can be continued beyond this period.

Local support: Foreign applicants will receive full support in transferring to Czechia. Knowledge of Czech is not required but the successful applicant will be offered support to take up language courses and reach a basic level of proficiency.

Documentation submitted: Applicants should send full application consisting of (1) cover letter outlining your skills and interest in the position, (2) CV including full publication list, (3) copies of relevant diplomas, (4) documents proving 2 years of research work outside the Czech Republic during the last 3 years, and (5) contact details for at least two academic referees.
