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. 🌍🌐

Never have I seen such clear admixture plots in a marine species!
Our lab's whelk trilogy is complete! B. undatum barely move from home and appear to not cross deep-water channels, reinforcing concerns they could be locally overexploited. Out now in Evol App w/ great colleagues at DFO onlinelibrary.wiley.com/doi/10.1111/...
Calling all Canadian prospective grad students! Domestic PhD & MSc application deadline = Jan 9 for EEB @ U. Toronto! Great community of researchers! Guaranteed funding >$40k/y! Join us! eeb.utoronto.ca/education/gr...
Our department is pretty great!

Hovering—maintaining a fixed position in the water—is energetically expensive for fish. A study finds hovering is twice as metabolically expensive as resting. In PNAS: www.pnas.org/doi/10.1073/...

🐌 🌊 Very first paper from my wonderful MSc student Jon Kubelka: combining genomics & demographic data in the exploited gastropod Buccinum undatum. Genetically well-mixed population, but harvesting size limits --> targeting sexually immature individuals. Read for FREE! tinyurl.com/mr5exs2w
🚨New postdoc positions available: we are looking for 2 postdoctoral researchers to join a large, collaborative effort to document, describe, and investigate the biodiversity of tiny, cryptobenthic fishes in the Indo-Pacific 🤏🐠🧪. More details: fishandfunctions.com/join%F0%9F%9...
