Theoretical Ecology Webinar

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 (, Géza Meszéna ( and Chris Terry ( Any comment, or suggestion are welcome.

Adam Clark (Graz): Measuring ecological stability in systems without static equilibria

31 May, 2022

Ecological systems are typically characterized by complex dynamics, with central tendencies that vary greatly over time. However, most empirically tractable metrics used to measure stability in ecological systems assume the opposite – i.e. that dynamics are simple, and centred around a single static equilibrium. Here, I suggest a heuristic approach for analysing complex ecological dynamics by separately quantifying effects of observation error, process noise, and deterministic dynamics.
