PhD Arctic Greening – Plant-Soil-Interactions

100%, Zurich, fixed-term

Climate warming is transforming the Arctic at an unprecedented rate. Previously barren landscapes are “greening” as a result of longer snow-free periods and increases in plant growth. Although the Arctic is warming almost everywhere, patterns of Arctic greening and changes in the Arctic biosphere are highly diverse. As Arctic landscapes continue to change, we need to understand the biological and physical-chemical feedbacks associated with the Arctic’s transition into this novel state. 

Project background

For a new project funded by ETH Zurich’s highly competitive internal Research Grant Program, we are looking for three highly motivated PhD candidates to work on interdisciplinary approaches to develop a deeper understanding of the evolutionary, ecological and biogeochemical processes underlying Arctic greening. One of the main objectives of this project is to test how far the observed vegetation changes throughout the Arctic are tied not only to warming, but to changes in soil properties and soil microbial communities. 

We will study ecosystems of the High-Arctic Svalbard Archipelago and northern Norway to determine the underlying interactions between plants, soils and microbial communities across geoclimatic gradients. For this we will work in interdisciplinary teams using experiments that have been designed to assess the response of Arctic ecosystems to warming and how soil-vegetation-microbial interactions will govern the pace and shape of Arctic greening, Arctic biodiversity changes and biogeochemical cycles. The project is led by a consortium of researchers from ETH, WSL and NINA.

Job description

Your primary PhD supervisor will be Jake Alexander and your main responsibilities will be to access adaptation and response of plant communities to soil development in the warming Arctic. This includes the following tasks:

  1. Asses soil development in relation to parent material and its susceptibility to weathering
  2. Determine plant community structure, adaptations and strategies as drivers for Arctic greening
  3. Assess the evolutionary potential of a model plant (Silene acaulis) to respond to climate change
  4. Investigate interactions between climate, competition and soil development as constraints on plant performance

Your profile

 

  • Fluent in English (oral and writing) and excellent communication skills 
  • High level of motivation for the scientific content of the project
  • Interest in participating in scientific communication (written and spoken)
  • Strong communication, collaboration, active listening, and problem-solving skills
  • Proven field work experience and/or proven ability to operate effectively in remote/harsh regions
  • Independent, self-organized, solution oriented work approaches
  • Experience with/motivation for interdisciplinary work
  • Creativity and flexible thinking
  • Flexibility and willingness to stay abroad for longer periods of time for work
  • Ability to independently conduct statistical data analysis 
  • Valid driving licence

For the "Plant-Soil-Interaction PhD", the following specific skills are required:

  • Driven by an interest in plant evolution, natural selection and species interactions
  • Strong interest in soil development, weathering and its impact on soil nutrient dynamics
  • Background in plant biology, ecological genetics, community and/or ecosystem ecology
  • Basic knowledge of molecular bioinformatics (asset)
  • Knowledge of practical plant species identification, plant community categorization
  • Interest in manipulative experiments to assess plant responses to natural selection and the genetic basis of evolutionary processes
  • Can sustain intense manual work on phenotypic traits from experimental populations (field and greenhouse) and generate large, clean datasets for analyses
