Understanding biodiversity for a better future.


We study ecosystems from the top down and from the bottom up to understand how the world stays green.

The interactions that link species to one another are the building blocks of biodiversity. In our work we are broadly interested in the eco-evolutionary feedback loops that drive species interactions.

To uncover these, we combine experimental, and molecular approaches with field surveys and mathematical modelling. These complementary approaches allow us to pinpoint the processes by which natural communities are structured and how they function.

This offers irreplaceable insight to understand how our biodiversity is responding to ongoing global change, and how we can improve sustainability of the global food production system.

Research

Key Research Themes

Long-term ecology

Long-term nature observation series are indispensable records of how individual populations and species are responding to environmental change. In the Research Centre for Ecological Change we are systematically collecting long-term ecological data for an unprecedented syntheses of how communities of organisms are responding to change.

Biodiversity in a changing world

We are studying how natural communities are responding to global change and how interactions among species across trophic levels are changing as well.

Global plant demography

As part of PlantPopNet, we are driving a coordinated global effort combining data and theory to understand abiotic and biotic drivers of population persistence and distribution in a changing world.

Biological diversity and sustainable food production

Humans have intensified and mechanized agricultural processes in an effort to boost efficiency, productivity and profits. As a result, global food systems are increasingly generating severe social, environmental, economic and climate costs. We are investigating how mechanisms that promote stability in natural ecosystems could be utilized to develop sustainable and climate-smart food production systems.

Intraspecific variation in host-parasite interactions

Understanding how diversity is maintained in host and parasite populations is one of the core challenges in disease biology. Using long-term population dynamic data combined with genomics and experimentation, we address this question in a natural plant-pathogen interaction. This work brings us one step closer to answering questions of how risks of virulence and pathogen occurrence evolve – important questions from both basic and applied points of view.

Pathogen communities

Across biological systems it is becoming increasingly clear that host populations and even single host individuals are typically exploited by diverse pathogen communities. In our work we aim to understand the spatio-temporal determinants of this diversity, and what the eco-evolutionary implications are for both hosts and pathogens.

Getting here

We are located in building Y13 at the Irchel campus of the University of Zurich.

Arriving by public transport

From the Zurich main station (Hauptbahnhof or HB), tram stop Bahnhofplatz/HB:

-Take tram 10, direction Seebach, to the stop “Universität Zürich” (about 13 min).
-Take tram 14, direction Seebach, to the stop “Michbuck” (about 11 min). From there walk through the park to the campus building.
-Take tram number 7, direction Stettbach, to the stop “Milchbuck”. From there walk throught the park through the campus buildings.

This is the blue cow, a popular meeting point at the Irchel campus.

Tip: a 24 hour ticket within zone 110 is valid for any number of rides and costs the same as two single rides. Note that you have to buy your ticket at a tram stop, train station or using an app (ZVV, SBB). No tickets are sold inside the tram.
