[8 Nov 2025] Another roundup of #ConservationJobs, mostly in 🇨🇦. All postings include salary. I am not involved in these positions. Please share to help others — working to conserve nature is rewarding and needed! www.linkedin.com/posts/aerinj...

Saddened for all the students applying to the NSF GRFP who feel they can’t bring their full selves to their personal statements this year. Science is better with you in it. I hope you get the funding and keep doing excellent work.

Work from @brynnjohnson13.bsky.social's thesis investigates why neighboring hybrid zones between orangethroat and orangebelly darters followed different trajectories: long-term coexistence vs. collapse. Warming amplifies competitive asymmetry, influencing whether hybrid zones persist or collapse.

Does #SexualSelection fuel #Speciation? Our new #meta-analysis of comparative studies finds support for a positive relationship, but the rather moderate global effect suggests it’s not necessarily a dominant force. doi.org/10.1093/evle...

1/9 New in @science.org www.science.org/doi/10.1126/science.ado8005 How does genetic architecture constrain evolutionary trajectories? To address this question, we inferred the genetic architecture of convergent plumage coloration and its evolutionary history in wheatears.

No better reason to join Bluesky then to say the first chapter of my PhD is out as a preprint! New surgeonfish phylogeny, ecomorphological relationships, evolutionary shape correlations-with NEW method to accurately account for phylogenetic covariation among shapes! www.biorxiv.org/content/10.1...

Pumped to share our work on bird behavior and the 2024 Eclipse, in today's @science.org. 100k bird vocalizations + 10k continent-wide observations from the public = really fun collab led by Liz Aguilar, with @juncowren.bsky.social @mathcancer.bsky.social @imillercrews.bsky.social #NSF

When sex chromosomes turnover, they can reset the rules of genomic conflict. New preprint exploring how turnover reshapes barriers to gene flow through an “escape-hatch” model for mitonuclear conflict. Any feedback would be welcome! ecoevorxiv.org/repository/v...

I really hope this is successful! Please apply! Contact me if you have questions!

Today my @nytimes.com colleagues and I are launching a new series called Lost Science. We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires. Gift link: nyti.ms/3IWXbiE

"Useless" and/or "silly" federally-funded research has turned the United States into the world’s leader in science and technology over the past 75 years. Such science is under attack throughout the federally-funded agencies in the United States. More at: www.americanscientist.org/article/%E2%...

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/... ), we find the opposite: animals exchange genes more, and for longer, than plants

Another pre-print led by @wrad07.bsky.social 🐟🧬 We generated a reference genome for Hypostomus & used whole genome re-sequencing to ID invasive suckermouth catfish species in TX. We also investigated genetic sex determination to assess feasibility of genetic biocontrol via YY supermale approaches.

First pop gen paper from our lab! We find repeated evolutionary turn over of sex chromosomes in darters contributes to reproductive isolation. Turnover may be an escape hatch to resolve mitonuclear conflict & neo sex chromosomes evolved via a rare recessive mutation. www.biorxiv.org/content/10.1...

"A single gene orchestrates androgen variation underlying male mating morphs in ruffs" New paper featuring @fusanilab.bsky.social out now in @science.org ! www.science.org/doi/full/10.... www.science.org/doi/full/10....

Why do males and females often differ in traits? The expected answer: selection. But our new paper in GENETICS shows that genetic drift alone can generate sexual dimorphism — even when male & female optima are the same

Check out our new paper! We find cavefish colonized caves 3x and global cooling events may have influenced these events. royalsocietypublishing.org/doi/10.1098/...

I am thrilled to share this paper outlining some ideas I’ve been thinking about for a little while on a simple but powerful approach for predicting risk of inbreeding depression from long runs of homozygosity and non-ROH heterozygosity. 1/n @klohmueller.bsky.social doi.org/10.1016/j.tr...

Great to see this paper out I contributed to:

Extremely grateful to have presented the first half of my first project on darter sex chromosomes at #Evol2025 - stay tuned for the preprint coming soon!!

Very exciting to present this idea at #Evol2025. The toxins and pigments of aposematic animals often act against infections, providing animals with individual fitness benefits.

Thrilled to share that my grad student Zach Heiple won the 2025 Ernst Mayr Award at #Evol2025 for his PhD work on how deep-sea fishes evolved their extreme tubular snouts! 🐡🎉 SSB’s top honor for the most creative student research in systematics @scrippsocean.bsky.social @ucsandiego.bsky.social

Genome size is surprisingly variable even WITHIN species. Dunja Lamatsch, Martin Haase, Maria Pilcher, and I use flow cytometry to show a nice example of this variation in this new paper, perhaps connected to a resolving whole-genome duplication, in our snails. 💜🐌🧬 doi.org/10.1098/rsos...
