The Research Training Group "R³ - Responses to biotic and abiotic changes, Resilience and Reversibility of lake ecosystems" funded by the Deutsche Forschungsgemeinschaft (DFG) and based at the University of Konstanz welcomes applications for a

PhD-Position

(Salary Scale 13 TV-L / 65%)

for a motivated student interested in gaining a Ph.D. in the field of Limnology/ Plankton Ecology. The contract is limited to three years. The position is to be filled as soon as possible. The position is placed in the research project "The role of mixotrophs for carbon flow dynamics and nutrient regeneration" and deals with the idea that during oligotrophication of Lake Constance, P-recycling patterns and the functioning of the whole microbial food web were crucially affected by an increase of mixotrophic bacterivores (flagellates). The work involves laboratory experiments in chemostats with model food webs and chemostats with natural food webs, using inocula from the lake. Impact of different bacterivores on the bacterial community will be determined by 16S rRNA gene amplicon-sequencing. Your profile: The candidate should have a Master degree in Biology, preferably with some knowledge in Aquatic Ecology or Limnology, and should be interested in laboratory techniques like chemostats and microcosms. Further requirements include the capability of conducting independent research, scientific writing, good communication skills in English, and amenability to work with project partners. Proficiency in German is advantageous but not a requirement. The successful candidate should show an exceptional level of motivation, and readiness to push a demanding research project forward. We offer:

• a structured Ph.D. program within the Research Training Group R3
• working in a young creative team
• an interesting and dynamic working environment
• innovative multifaceted research activities
