PhD Assisted Migration

100%, Zurich, fixed-term

The Plant Ecology Group at ETH Zürich is seeking an enthusiastic PhD candidate to study the factors underlying the success of assisted migration of mountain plants threatened by climate change. The PhD candidate will be based in the Plant Ecology Group at ETH Zürich under the guidance of Prof. Jake Alexander, and will collaborate with the Ecology Group at the University of Basel, led by Prof. Sabine Rumpf, and the Flore-Alpe Alpine Botanical Garden, directed by Prof. Christophe Randin.

Climate change is shifting the spatial distribution of suitable habitats for many species. However, the majority of mountain plant species are unable to disperse quickly enough to higher elevations in response to these changes. Assisted migration may become a vital part of ecological restoration and conservation efforts aimed at mitigating the risk of extinction due to climate change. Currently, in Switzerland and beyond, policies concerning assisted migration are in the early stages of consideration, and crucial knowledge and experience are needed to enhance the success of these projects.

Job Description

The PhD candidate will engage in a broader project that involves scientists, policy makers from federal and cantonal administrations, and practitioners from conservation and industry. The overarching goal is to establish guidelines and initiate an assisted migration program for mountain plants in Switzerland that face threats from climate change. The PhD candidate's responsibilities will include:

  • Collecting ecological data to assess the reasons for rarity and ecological limits (niche, range) of threatened mountain plants,
  • Understanding the variation in success of assisted migration projects,
  • Collecting and statistically analyzing demographic monitoring data from natural populations,
  • Setting up and conducting field transplant experiments, and
  • Conducting ecological niche modeling of focal species.

The PhD candidate will also have the opportunity to develop independent analyses within this broad theme and is expected to contribute to group responsibilities, which may include teaching, outreach, and lab activities within the department and university.

Profile

  • Enthusiasm for the scientific aspects of the project,
  • Interest in participating in transdisciplinary research that fosters transformative change,
  • Familiarity with plant identification, propagation, and trait measurements,
  • Ability to work both independently and collaboratively,
  • Commitment to a collegial and inclusive workplace,
  • Strong skills in statistical modeling (e.g., mixed models, species distribution modeling, statistical programming in R),
  • Fieldwork experience and a valid driver's license,
  • Willingness to travel for extended fieldwork for data collection,
  • Advanced English language skills (both oral and written).

Workplace

The Plant Ecology Group at ETH Zürich conducts research on a variety of topics within plant community ecology, examining factors such as climate influences, biotic interactions, and demographic lags in range shifts and community dynamics. The group explores the drivers of biological invasions, alpine wildflower phenology, forest regeneration constraints, and utilizes community science to engage the public in ecological research. The group is deeply committed to diversity and inclusivity in all activities and promotes collaborative science. For more information, please visit our website.

Funding is available for four years of PhD studies, starting at 52,500 CHF per year (before taxes), as per the standards of the Department of Environmental Systems Sciences (USYS) at ETH Zürich. All members of the Plant Ecology Group are involved in teaching and mentoring bachelor’s and master’s students.

This project provides exceptional opportunities for collaboration with the University of Basel and the Flore-Alpe Alpine Botanical Garden. Additional interactive opportunities are available through research groups at ETH Zürich, the adjacent University of Zürich, WSL (the Swiss Federal Institute for Forest, Snow and Landscape Research), and EAWAG (the Swiss Federal Institute of Aquatic Science and Technology). Zürich offers a cosmopolitan lifestyle with high living standards, easy access to research sites, outdoor activities, and the rest of Europe.
