🚨Our new preprint is out! 🤩 🌟 Mutation rates vary widely across taxa, and decades of research have sought to explain why. ♀️♂️ Reproductive modes, and evolutionary shifts between them, could help explain some of this variation. ❓ So what does the evidence tell us? 👀 Read our preprint to find out!

I know lots of Canadians want to celebrate this as a “win” but it isn’t. We have consistently underfunded our universities and research capacity for decades. Adding big names that eat up a lot of capital will not improve our science at all. #Canada www.ctvnews.ca/sci-tech/art...

🚨 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

Moir et al. (2025) asked how pollinators drive geographic floral divergence in Brunsvigia gregaria with a generalist pollination system. Style length correlates with the body length of locally important pollinators, highlighting their critical role in floral evolution. #Ecology bit.ly/4aEqb8u
The title of the paper, 'A test of the Grant–Stebbins pollinator-shift model of floral evolution,' published in New Phytologist.Graphs showing how floral morphology in B. gregaria aligns with pollinator body size and contact probability. The first two graphs show that mean style length increases with pollinator body size (weighted mean pollinator body length and the mean body length of the most important pollinator group). The other two graphs show the probability of contact with floral reproductive parts by ubiquitous pollinators: honeybees contact them more often at short-style sites, while bee flies show no significant difference among sites.
