Doctoral Student Range shifts of mountain plants

The Plant Ecology Group at ETH Zürich is seeking a doctoral student to study why mountain plant species are failing to shift their ranges fast enough to track climate change. The candidate will be based in the Plant Ecology Group at ETH Zürich, Switzerland (Prof. Jake Alexander), and work in close collaboration with the Hargreaves Lab at McGill University, Canada (Prof.

Anna Hargreaves). While range shift lags are well documented across taxa and regions, we have a much poorer empirical understanding of the demographic processes explaining lags, hindering our ability to forecast which species will track climate change, or which management practices might aid shifts of valued species or delay shifts of problem species. The candidate will conduct empirical research within a larger project focused on closing key knowledge gaps about the mechanisms underlying plant range shifts in mountains.

Many species are not shifting their ranges fast enough to successfully track climate change, yet attempts to predict the velocity of plant range shifts have generally failed. Partly this is because we still lack empirical data to quantify the processes needed for species to disperse to new locations and establish viable populations there. We have a particularly poor grasp of long‑distance dispersal rates, and how propagule origin and biotic interactions constrain establishment beyond species’ ranges.

Focusing on mountain plants, this project aims to disentangle the importance of the species interactions and demographic processes governing shifts of plants’ high‑elevation range limits. It will further test whether an improved understanding of these processes can be used to predict range shift ability across ecosystems. By combining global, standardized experiments across six continents within the Mountain Invasion Research Network (MIREN), and detailed studies in two core mountain regions (Swiss Alps, Canadian Rocky Mountains), the project robustly tests competing hypotheses about mechanisms of range shifts while generalizing across a diverse geographic context.

• Within the wider project, the role of the doctoral student will be to set-up and run field transplant and greenhouse experiments, and collect and statistically analyse ecological data allowing the quantification of plant demography and long-distance seed dispersal by animals
• They will also have the opportunity to develop their own research questions within the broader topic of the project
• In addition to research activities, the doctoral student will contribute to tasks and responsibilities (e.g. teaching, outreach, lab activities) within our research group and department
• Work will be conducted in parallel with a sister study in the Canadian Rocky Mountains (a similar position is being advertised at McGill University – see here, Students are welcome to apply to both if they are interested in working in either country, but the application processes are separate) and with international collaborators from the MIREN network

• An MSc in ecology or a related field
• High self-motivation
• Ability to manage time effectively
• Commitment to a collegial and inclusive workplace
• Proven skills in statistical modelling (e.g. mixed models, statistical programming in R) and in scientific writing
• Eagerness and ability to engage in extended periods of field work, sometimes in remote areas and under challenging conditions
• Advanced language skills in English (oral and writing), and an ability to write efficiently and effectively
• Professionalism and academic integrity

Additionally, the project will require the following skills (some of which may also be acquired during the project):

• Experience conducting ecological research under field and greenhouse conditions
• Familiarity with plant identification, propagation, and trait measurements
• A valid driver's license, and ability to drive on steep mountain roads
