The Department of Biology, Faculty of Science, at the University of Copenhagen (UCPH) is offering a PhD position in Terrestrial Ecology on moss-cyanobacteria associations commencing 15.03.2021 or as soon as possible thereafter.

Description of the scientific environment
The successful applicant will be based at the Ecosystem Ecology group, Terrestrial Ecology Section, thereby joining a lively research environment covering a wide range of topics such as plant ecophysiology, biogeochemistry, diversity, soil biology and ecosystem-atmosphere interactions. Our section is a diverse group comprising research and teaching staff members, laboratory technicians, PhD candidates and MSc and BSc students, focussing on many aspects of plant- and microbial activity, nutrient cycling and global change. The section has state-of-the-art laboratory facilities and substantial experience in conducting laboratory and field-based experiments.

Project description
The PhD position is part of a 5-year Starting Grant financed by the European Research Council (ERC) lead by Tenure-Track Assistant Professor Kathrin Rousk.

The aims of this project is to (1) identify the effects of abiotic factors (i.e. moisture availability, temperature) on moss-associated nitrogen (N2) fixation in contrasting ecosystems -boreal and tropical forests. For this, samples will be collected in boreal forests as well as in tropical cloud forests and N2 fixation will be assessed in different moss species under controlled conditions in the K Rousk lab at the Dept. of Biology at UCPH. Samples will be exposed to a range of temperatures and moisture levels and N2 fixation will be measured using a combination of the acetylene reduction assay (ARA) and 15N-N2 tracking. In parallel with the assessment of N2 fixation, the abundance of the cyanobacterial colonizers (e.g. phycocyanin assays) and the bacterial community composition will be identified using DNA sequencing. The second aim (2) of this project is to determine the nutrient exchange, and thereby the nature of the relationship moss and colonizing cyanobacteria share using nanoSIMS.

Principal supervisor is Tenure-Track Assistant Professor Kathrin Rousk, Dept. of Biology, kathrin.rousk@bio.ku.dk. Co-supervisor is Prof. Anders Priemé, aprieme@bio.ku.dk, Dept. of Biology.

Job description
The position is available for a 3-year period and your key tasks as a PhD student at SCIENCE are:

Formal requirements
Applicants should hold a MSc degree or equivalent in biology, ecology, microbial ecology, molecular biology, biogeochemistry or a closely related field. As criteria for the assessment of your qualifications, emphasis will also be laid on previous publications (if any) and relevant work experience.

We are seeking a highly motivated and ambitious individual with good interpersonal and communication skills. Previous experience in collecting of and working with live plant material; stable isotope tracking; microbiology; molecular biology techniques such as DNA extraction and DNA sequencing; cell biological techniques such as fluorescence microscopy will be considered a plus.

Fluency in spoken and written English is a requirement.
