The University of Copenhagen is offering a 3-year PhD position in marine microbial ecology in the 2021/22 academic session
The position starts 1. April 2021 or as soon as possible thereafter and will be associated with the 4-year research project “Future stimulated nitrogen fixation: threatening the health of coastal ecosystems?” funded by Independent Research Fund Denmark. The project is a collaboration with scientists from University of Southern Denmark (Carolin Löscher), Aarhus University in Roskilde (Stiig Markager), the Baltic Sea research Institute, Warnemunde, Germany (Maren Voss), and Boston University, Rhode Island, USA (RW Fulweiler).
The import of nitrogen (N) through biological N2-fixation is essential for plankton productivity in vast areas of the global ocean. In fact, this conversion of N2 gas to ammonium available for growth is fuelling up to 50% of the new production in some regions. N2-fixation in Danish coastal waters has been largely overlooked and climate change is predicted to stimulate this activity. Important N2-fixing organisms likely include cyanobacteria advected from the Baltic Sea and heterotrophic bacteria. The aim of the overarching project is to determine the importance of benthic and pelagic N2-fixation in Danish marine regions, in the face of climate change.
Two PhD students will be employed within the project: one at University of Copenhagen (UCPH) focusing on pelagic processes, and one at the University of Southern Denmark focusing on benthic processes. The two students will collaborate closely with respect to sampling and sample analyses. The UCPH PhD student will focus on the magnitude and seasonality of N2-fixation in Danish coastal waters, molecular identification of the actively N2-fixing groups, and identification of the environmental conditions governing their fixation. The work will entail cutting-edge molecular, physiological, and biogeochemical approaches (Real-Time PCR, high-throughput sequencing, metagenomics, bioinformatics, and 15N tracer techniques, including nano-SIMS) in association with laboratory studies and field sampling.
The successful candidate will become an integrated part of the research group of Lasse Riemann. The group works with many aspects of marine microbial ecology, but N2-fixation is a main research focus. The project will be carried out in the Marine Biological Section located in Helsingør, 30 km north of Copenhagen.
Principal supervisor is Professor Lasse Riemann, Marine Biological Section, Department of Biology, E-mail [email protected]
