🚨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!

A final new paper out from the lab, work from Steve Johnson, @joannarifkin.bsky.social & @stepheniwright.bsky.social We asked what maintains the striking variation in floral color, size, and shape within and among populations of Dame's Rocket, Hesperis matronalis

Color, size, shape: The drivers of floral variation in Hesperis matronalis (Dame’s Rocket)
Evolutionary biologists have long been intrigued by the factors that sustain genetic and phenotypic variation within and among natural populations. Polymorphisms underlying components of floral displa...

New work now out led by Mark Hibbins and Cassandre Pyne : new statistical methods for quantifying rearrangements suggest highly elevated rates of chromosomal change associated with the evolution of separate sexes in Rumex!

Congrats to Dr. Meng Yuan, who defended her PhD on the genome-wide potential for ploidy & sexual conflict in plants! Many thanks to @judithmank.bsky.social for serving as her external examiner. A fun collaboration w/ @stepheniwright.bsky.social and also @stuartmcdaniel.bsky.social for a paper!

Waterhemp has recently evolved separate M & F sexes from a monoecious ancestor. @jmkreiner.bsky.social @stepheniwright.bsky.social &co reveal surprising #chromosomal complexity associated with this transition, challenging assumptions of how separate #sexes evolve @plosbiology.org 🧪 plos.io/46sTg6u

I'm recruiting a PhD student to join my lab at the University of New Orleans starting in Fall 2025. Research topics will focus on building and using phylogenies to study the diversification of birds, with an emphasis on Neotropical bird radiations. Contact me if interested.
