Paper published, led by Forest Isbell.
We developed a new theoretical framework to predict how temporal stability and resilience emerge from the combined effects of resistance and recovery.

Many thanks to Drs. Akira Mori (@akkym.bsky.social), Shinichi Tatsumi and Xinyu Xu for the invitation to present at their Biodiversity and Ecosystem Functioning Symposium at the Ecological Society of Japan Annual Meeting in Kyoto. Wonderful to be part of such a great lineup of speakers! #ESJ73 #BEF

New predictions for how temporal stability and resilience depend on their resistance and recovery components are explored.
New in @pnas.org: Ecological stability through nonlinear fluctuations and the portfolio effect
We show that nonlinear dynamics like oscillations and chaos are paradoxically key to stabilizing globally important salmon complexes in the Fraser River and Bristol Bay.

Really cool - "Stocks must therefore be orbiting the [shared] attractor asynchronously to produce the observed uncorrelated fluctuations." Inspiring statement.

An exploration of chaos theory in population dynamics showed that unpredictable systems can often be modelled using surprisingly simple mathematics.

A global analysis of marine fish populations involving 243 recruitment and 266 spawner time series across 143 species finds that nonlinear dynamics are widespread and that the degree of nonlinearity is amplified by temperature variation and in fast-lived species 🧪 www.nature.com/articles/s41...

New in @natecoevo.nature.com, we show that nonlinear dynamics like oscillations & chaos occur in 81% of marine fish populations worldwide. Nonlinearity was correlated with the magnitude of fluctuations & amplified by temperature variation & in fast-lived species. 🌍🌐
