Fifty years since a simple equation described the chaos of biology
An exploration of chaos theory in population dynamics showed that unpredictable systems can often be modelled using surprisingly simple mathematics.

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. Link: doi.org/10.1073/pnas... 🌐🐟

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. www.nature.com/articles/s41...
Predicting temporal stability and resilience from resistance and recovery - Nature
New predictions for how temporal stability and resilience depend on their resistance and recovery components are explored.

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
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...

Robert Hechler@roberthechler.bsky.social · 8mo agoNew 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. 🌍🌐 Link: doi.org/10.1038/s415...

New preprint! We analyzed ~500 global marine fish time series using #EmpiricalDynamicModeling and show that temperature variation amplifies nonlinearity in juveniles and adults, while life history mediates nonlinearity for the latter, dampening it in slow-lived species #Ecology #Fisheries
Temperature variation and life history mediate the degree of nonlinearity in fluctuations of global marine fish populations
Nonlinear dynamics readily occur in natural ecosystems and can drive irregular population fluctuations through oscillations, chaos and alternative stable states. However, the effects of anthropogenic ...
