Are warmer oceans good or bad for #fish? 🐟 The answer is a dangerous paradox. Our new paper in @natecoevo.nature.com shows how marine heatwaves may create “fake” fish gains that mask a large-scale crash. Read our findings here: www.nature.com/articles/s41...

When I scan through open peer reviews I'm surprised by how rarely people comment on the design of visuals. I've been working to develop a constructive approach to critique and have been trying them out on the Tube. Here's the latest www.youtube.com/watch?v=zWpt...

Degradation of fish food webs in the Anthropocene The decrease in body size driven by the selective species turnover is widely altering fish food web topology and function.

New paper out examining fish food web degradation in the Anthropocene. We show the structure of aquatic food webs are changing-- even when species richness doesn’t. These signals are strongly associated with decreases in body size within fish communities. www.science.org/doi/10.1126/... 🌐🐠🐡🦈🐟

What happens when fish communities shift towards smaller species?🐟
Global study led by alumnus @juancarvq.bsky.social shows widespread changes in food webs across marine & freshwater systems. Even where species numbers stayed stable, interactions & body size changed.

Happy birthday to one of my favourite haters, Charles Darwin

Just discovered the wonderful covers of 'Genes to Cells', the journal of the Molecular Biology Society of Japan @mbsj-official.bsky.social – absolutely beautiful!

here some examples inspired by mitosis, CRISPR, the DNA helix, and plant pigments

A new and exciting @nature.com Communications study reveals baleen whales operate the planet's largest nutrient transport system, moving tons of nitrogen and carbon from polar feeding grounds to tropical breeding areas. Great job @jjkiszka.bsky.social and coauthors ✨

Scientist in the field sampling DNA

Protected Areas are important for global conservation. However, their impact on genetic diversity has long remained unclear.

Check out our new paper lead by @chloology.bsky.social which answers this question for mammals and fish. 🧪

The Idiot's Guide to Effective Population Size This is a reference manual for the elegant, yet hideously complex concept of effective population size (Ne), inspired by a classic, self-published manual of automotive repair ‘for the compleat idiot’...

Immediately assigning this new paper to my pop gen students! Waples publishes some real hits - "What is a population?" is another instant classic onlinelibrary.wiley.com/doi/10.1111/...

PhD Advertisement that reads: I am recruiting a PhD student to join MacroSize, a new international research network advancing hypotheses and theories on intraspecific body size variability in fish. The selected candidate will co-develop the project, analyze large datasets, and collaborate closely with MacroSize members, including co-leads Pablo Tedesco, Ignasi Arranz, Xingli Giam, and Juan Carvajal-Quintero. To apply, Send your CV and a motivation letter to juan.carvajal@dal.ca. Applications are open now and will be reviewed on a rolling basis. Start date September 2025 (flexible).

PhD project alert! 🚨 I'm recruiting a PhD student to join my lab and the MacroSize network to investigate the trends, patterns, and processes driving intraspecific variation in fish body size in the Anthropocene. Exciting opportunity to explore ecological dynamics in a changing world! :) 🌎🐟🐠🐡
