Excited to be attending #Evol2026! I'll be talking about the genetic basis of local adaptation in the face of high gene flow: it may or may not have something to do with structural variants! Come see my talk next Wednesday at 2.30 pm in the "Adaptation: Inference of Selection" session (room 24)

Out today in @cp-trendsecolevo.bsky.social our paper “Second Thoughts about First Principles in Biology.” www.cell.com/trends/ecolo... . We are in favour of first principles approaches in biology but we think that we need to do better in how we use them.

Metabolic scaling is thought to scale very steeply with size in unicells but what if that steepness is simply an artefact? Out today in Ecology Letters, we show that metabolic scaling is not superlinear in unicells but instead scales at ~0.86 onlinelibrary.wiley.com/doi/epdf/10....

Out today in @science.org our paper on how evolutionary adaptation to warming will reduce fisheries yields. Please let me know if you need me to send you a copy. Summary of the paper coming soon. www.science.org/doi/10.1126/...

Fish will have to adapt to a warming world, what will that adaptation do to fisheries yields? We answer that question today in Science. I’ll summarise our findings very briefly in this thread www.science.org/doi/epdf/10....

Is hermaphrodism less common in animals because it is energetically more costly? George Jarvis and @djmmeeg.bsky.social have analysed 536 species of marine invertebrates and found that hermaphrodites require approximately 27% less energy than gonochores on average. doi.org/10.1098/rspb...

Was Darwin wrong? Hermaphrodites found to be more energy efficient than animals with two sexes monash.edu/science/news...

Excited to share our study testing competing theories on the energy dynamics of hermaphroditism! Grateful to @djmmeeg.bsky.social for guidance, to Thomas Brey for metabolic rate data, and to Deborah Charlesworth for feedback. Thanks also to the editors and reviewers at Proc B. @royalsociety.org

Darwin speculated that it was energetically costly to be an hermaphrodite. He thought that might explain why they were relatively rare in animals. Our paper out today tested this conjecture for the first time. royalsocietypublishing.org/rspb/article...

Another cool genome assembly: The first phased, annotated, chromosome-level assembly for a reef-building tubeworm, Galeolaria caespitosa! The species has 11 autosomal chromosomes and no sex chromosomes.

Hiring a postdoc! For #NSF project on oyster metapopulations and restoration, led by Max Castorani at UVa. Two year position based at UVa, OSU, or remote. Ideal for PhDs in quant ecology or oceanography. Apply by March 1. Message me with questions! jobs.virginia.edu/us/en/job/R0...
