New study from my lab! Led by prior student Sasha Bishop, along w/ co-author @johnstinchcombe.bsky.social 🌸 We performed a resurrection study on morning glory and found that within 9 years, adaptive potential declined by 96%

A resurrection experiment reveals reduced adaptive potential in a common agricultural weed

Adaptive evolution is essential for populations facing rapid anthropogenic change, yet realized evolutionary responses often fall short of expectations. Us

Very unhappy to lose his hard-earned aroma in a bath.

Sad to report that my colleague Dr. Jim Hamrick - a giant in the early study of plant population genetics, though in these 2017 photos he was contributing to the understanding of *barnacle* diversity - has passed.

Mankees are headed to #Evol2026! Come see my talk- Sexual Selection Maintains Ancient Structural Polymorphisms- by Y Lin & @vdbijl.bsky.social, Tues 12PM in Sexual Selection & Recomb (Room 25A) and @jacejostles.bsky.social 's poster about Sam Snow's work on Mate Choice in the Age of AI.

So great to see @gbaucom.bsky.social 's SSE Presidential address on long- term weed evolution research program at #evol2026. She's had weeds in her sights since we were grad students together and has made such cool progress since.

We are recruiting a PhD student in my recently established lab at the Evolutionary Biology Centre, Uppsala! Come work with us on the evolution of alternative mating tactics in water striders!

Evolutionary Biology at Uppsala University@evobiouppsala.bsky.social · 3mo ago

Recruiting a PhD student on the evolution of mating behavior in water striders using deep learning behavioral tracking and brain transcriptomics. Looking for a curious, computationally strong candidate. Fully funded, 4 yr, Uppsala University. @corrallopeza.bsky.social uu.varbi.com/en/what:job/...

I had the best time at @zoology.ubc.ca's annual Debbie and Justin Wragg-Schmidt Zoology Spring Symposium! What a privilege to be invited as their plenary speaker and I got to nerd out with so many cool people! Was lovely being back in the motherland 🇨🇦 talking about corals 🪸

We're recruiting! We're looking for two graduate students to join us at UBC in Vancouver. Fully funded and open to global applicants, with flexible start-date. Topics include theory, bioinformatics, and microbiology. More details: asherleeks.com/apply #socialviruses #evosky #virosky 🧪

New MEC study led by @joellelafond.bsky.social shows that proliferation of transposable elements drives Y-chromosome degradation and facilitates dosage compensation in Poecilia picta, a guppy species 🐠 with young sex chromosomes 🧬. @wileyecology.bsky.social 🔗: doi.org/10.1111/mec.... 📷: J. Lafond

🚨 My very first postdoc paper is out! 🐠 We show that the Y chromosome of the swamp guppy (Poecilia picta) has rapidly degenerated, losing genes, shrinking, and filling up with transposable elements, while the X responds by exporting key male genes to autosomes. 🧵⬇️ 1/6 📷Joëlle Lafond

Very pleased to see this out. Our new Poecilia picta genome shows rapid Y degeneration in a young XY system — rapid gene loss and Helitron accumulation, plus compensatory gene traffic to autosomes. Led by @joellelafond.bsky.social with Yuying Lin & @squarehare.bsky.social doi.org/10.1111/mec....
