We operate an international seminar series on Theoretical Ecology via Zoom since September, 2020. With some exceptions, the hour-long events are held on every other Tuesday at 9 a.m. Pacific Time, which corresponds to 5 p.m. in London and 6 p.m. in Paris most of the time. Our invited lecturer speaks for cc. 20-30 minutes. The rest of the hour is for questions and discussions, which are often lively. The seminars are recorded and posted on our YouTube channel. We send out notifications before each lecture via email and Twitter. The webinar is organised by György Barabás (dysordys@gmail.com), Géza Meszéna (meszena.geza@ttk.elte.hu) and Chris Terry (christopher.terry@biology.ox.ac.uk). Any comment, or suggestion are welcome.

Oscar Godoy (EBD-CISC): How changing interactions shape species coexistence and non-equilibrium dynamics
10 November, 2026
A universal feature of nature is that interactions among species are variable in space and time. However, these changing interactions have rarely been incorporated into theoretical studies aiming to understand the maintenance of biodiversity. This talk introduces two complementary approaches to account for the effects of abiotic and biotic conditions on changing interactions. The first approach, coupling species’ performance with their interactions, provides a generalization of the definition of structural stability and connects disparate processes such as the stress-gradient hypothesis, the covariance between environment and competition, high-order effects, and niche packing. The second approach, accounting for time-varying interactions, provides a framework for studying the stability of ecological communities under non-equilibrium. By moving beyond static representations of ecological interactions, we can assess the maintenance of biodiversity under more realistic conditions and gain new insights into how communities respond to environmental change.
