PhD position in Evolutionary Ecology (4 years)100 %

How does the environment modify interactions between plant and microbial communities along an elevation gradient?

Plants and their microbes make up much of terrestrial biodiversity, and understanding how their interactions are changing under global change is critical for both natural ecosystems as well as food production. Applications are invited for a 4-year PhD position to study the community ecology of plant and microbial species interactions by combining experimental and observational field approaches.

Theory predicts that plant community structure and plant-microbe interactions can change along environmental gradients, yet evidence for how these factors interact with one another has remained scarce. Biodiversity and ecosystem productivity increase toward low latitudes and elevations, generating corresponding increases in the intensity of species interactions. However, the ecological consequences of such variation on relationships between plant and microbial communities is unknown. This project is part of a larger study aimed at using mountain ecosystems to understand the interaction between biodiversity and global change. The aim of this PhD project is to study plant communities and their impacts and responses to microbial species interactions across an elevation gradient in Alpine populations in Switzerland through a combination of experiments and observational surveys.

Motivated students with a MSc degree in biodiversity, ecology, disease ecology, plant biology, or other related fields are encouraged to apply. Prior expertise in botanical surveying, experimental design, statistical analysis, or molecular techniques are a bonus, but your most important assets are enthusiasm for research, motivation to learn new things, and ability to work independently while being an active member of a research team.

The project is supervised by Dr. Fletcher Halliday and Prof. Anna-Liisa Laine at the University of Zurich. The Laine lab has broad expertise in studying the ecological and evolutionary dynamics of species interactions in natural populations (e.g. Halliday et al. 2020 Nature EcoEvo, Laine et al. 2019 eLife, Sallinen et al. 2020 Nature Communications).

To apply, please send a single (!) PDF file merged from the following parts to jacqueline.moser@ CV (with possible publications included), a copy of your academic transcript records, contact details of two references (e.g. MSc thesis supervisor), and a cover letter (MAX 1 page) with a description of your researcher interests and why you would be a suitable candidate for the project. Please include the word “PhDCALANDA21” in the subject line.

Applications will be considered until the position is filled. The position is available from March 1, 2021.

Short video series on biodiversity

We published a series of ten short videos about environmental change and biodiversity. The episodes cover what biodiversity is, who benefits from it, who studies it, how they study it, what threatens it and what we can do about these threats.

The videos are aimed for school children between ages 11-16 and the content of the videos was brainstormed together with teachers in order to come up with a format that would suit the target audience. Click here for more information.

Funding for research aiming to develop climate smart agricultural practices

Our consortium proposal ‘MULTA: Multi-benefit solutions to climate-smart agriculture’ led by Prof. Jari Lisk received funding from the Strategic Research Council (Academy of Finland).

The food system is facing a need for a systemic change to harness its significant potential to mitigate greenhouse gas emissions while producing healthy food sustainably to a growing population under changing environmental conditions.

A promising future direction is to promote management practices that enhance the ability of soils to sequester atmospheric carbon dioxide. Regenerative agriculture supports also other sustainability goals, such as soil health and productivity, biodiversity, water quality, resilience and food quality.
