Understanding the stability of ecological communities is a matter of increasing importance in the context of global environmental change. Yet it has proved to be a challenging task. Different metrics are used to assess the stability of ecological systems, and the choice of one metric over another may result in conflicting conclusions. While the need to consider this multitude of stability metrics has been clearly stated in the ecological literature for decades, little is known about how different stability metrics relate to each other. I’ll present results of dynamical simulations of ecological communities investigating the correlations between frequently used stability metrics, and I will discuss how these results may contribute to make progress in the quantification of stability in theory and in practice.

Further Information
Dr. Sonia Kéfi is a Research Director at the the Evolution Sciences Institute (ISEM) in Montpellier, France (https://biodicee.edu.umontpellier.fr/who-we-are/sonia-kefi/).
She is also an external professor at the Santa Fe Institute and she was the recipient of the 2020 Erdos-Renyi Prize from the Network Science Society. Her research aims at understanding how ecosystems persist and change under pressure from changing climate and land use. In her works, she combines mathematical modeling and data analysis to investigate the role of ecological interactions in stabilizing and destabilizing ecosystems, as well as to develop indicators of resilience that could warn us of approaching ecosystem shifts.
