Check out the accompanying Research Briefing for a summary of background, methods, main results and what we think this means for marine fishes under climate change.

Our findings challenge assumptions of stable equilibria common to #fisheries management and #ecology more broadly. The results suggest that variability from climate change as well as fishing-induced age truncation may lead to larger and/or more frequent boom-and-busts.

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. ๐ŸŒ๐ŸŒ

Very cool study! I enjoyed the write up too. And of course Julian was up for the 4am wake-up calls haha - he's the best!

Our results challenge assumptions of stable dynamics and suggests nonlinear fluctuations of fish populations are magnified by size-selective fisheries and increasing environmental variability from global climate change

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
