The Institute for Biodiversity and Ecosystem Dynamics (IBED) in Amsterdam invites applications for a PhD candidate in Marine Microbial Ecology in the Department of Freshwater and Marine Ecology for the 2018/2019 academic session.

Their institute is one of the eight research institutes of the Faculty of Science at the University of Amsterdam. IBED covers a wide range of subjects in ecology, earth sciences and environmental sciences, including both fundamental and applied research.

Project description

Predatory lifestyles in marine phytoplankton
Predation of microbes is traditionally assumed to be performed by heterotrophic organisms. However, many marine phytoplankton species also feed upon other microbes, and thus combine the lifestyles of both plants and animals. The subcellular interactions between photosynthesis and heterotrophy within these mixotrophic organisms remain poorly understood, but are likely to have severe consequences for the biogeochemical flow of elements in the ocean. This project aims at identifying the environmental drivers controlling microbial predation by photosynthetic eukaryotes in the ocean and link them to the underlying molecular processes characterizing mixotrophic nutritional strategies.
In this project laboratory experiments with marine mixotrophs representative of different nutritional strategies will be performed and combined with fieldwork in two contrasting marine environments, the Mediterranean and Southern North Sea. Transcriptomic signatures of selected nutritional strategies will be identified in chemostat experiments. These will inform the interpretation of targeted meta-transcriptomes from natural microbial communities, from which microbial predators will be identified through RNA stable isotope probing.
If you are the selected candidate you will be based at IBED in Amsterdam where you will present your PhD-thesis. You will conduct fieldwork at NIOZ on Texel and the Institute for Marine Research in Barcelona (ICM-CSIC).

Worth of Award
The full-time gross monthly salary will range from €2,266 in the first year to €2,897 in the final year, according to the Dutch salary scales for PhD students.

  • MSc in Microbial Ecology, Aquatic Ecology, Marine Biology, Biological Oceanography or a related field;
  • experience with cultivation of micro-organisms;
  • experience with molecular techniques, preferably genomics/transcriptomics;
  • experience with fieldwork;
  • experience with bioinformatics analyses is desired;
  • ability to work in a multi-disciplinary research team;
  • excellent communication skills in English.
