Ecological tipping points and resilience: when it may occur and when not
Join AIMES, Earth Commission, Future Earth and WCRP for the webinar series that aims to advance the knowledge about tipping elements, irreversibility, and abrupt changes in the Earth system.
- Juan Rocha (Stockholm Resilince Centre) – Ecosystems are showing signs of resilience loss
- Helmut Hillebrand (Carl von Ossietzky University of Oldenburg) – Are there thresholds for biodiversity change?
- Q&A/ Discussion
Moderated by Awaz Mohamed (University of Hamburg)
Juan Rocha, Stockholm Resilience Centre
Juan C. Rocha is a research scientist at the Stockholm Resilience Centre where he co-leads the theme on complex systems. His research questions are oriented to understanding critical transitions: from regime shifts in ecological systems, to collective action in society. Currently he focuses on the idea of cascading effects: how a critical transition in an ecosystem in the world can impact the likelihood of other ecosystems tipping over. Juan is interested in methods for identifying resilience surrogates –good observables that can tell you how resilient a system is– as well as misperception of feedbacks and their consequences. He finds inspiration in complex systems science, the use of mathematical models, networks and other computational methods to understand social and ecological complexity.
Professor for Plankton Ecology at the Institute for Chemistry and Biology of the Marine Environment University of Oldenburg. He is very interested in the mechanisms that constrain and alter biodiversity in a variety of ecosystems. He likes to think about the complex nature of biodiversity change and ecological stability. Trained as an experimental ecologist, he has focused more on research syntheses and data analyses in recent years. Since 2017 he is founding director of the Helmholtz-Institute for Functional Marine Biodiversity at the University of Oldenburg [HIFMB], a collaboration between the University and the Alfred-Wegener-Institute Helmholtz Centre for Polar and Marine Research. HIFMB focuses on interdisciplinary projects on marine biodiversity and conservation.
