Attempted eradication of smallmouth bass promotes rapid evolution. Here's the study that is the focus of the Scientific American article: www.pnas.org/doi/10.1073/...

This manuscript was so much fun to write! Who thought we'd find an ongoing invasion in Dmel. TEs are so cool 😎

We discovered an endogenous retrovirus that's still spreading in natural D. melanogaster populations! It was horizontally transferred from D. erecta in Central Africa, so we named it "Kuruka", which means "jump" in Swahili. Read its cool story here: www.biorxiv.org/content/10.1...

Vertebral skeletal diversity in mammals is remarkable. How do the differences between vertebral size and shape develop and evolve? See how we tackled this question in our paper published in @natcomms.nature.com today!

Our paper on clonal expansions in Sperm is out in Nature www.nature.com/articles/s41...
If you are interested in working at an intersection of Mendelian genomics/Population genetics/Clonal expansions +Cancer genetics/ and of course mutagenesis, please rich out about postdoc in my lab

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

🚨 My lab is hiring at all levels!

Interested in animal origins & evolutionary cell biology?

I'm recruiting a postdoc, PhD students & a research assistant to study the molecular evolution of cell adhesion using marine invertebrates + comparative genomics.

Just an absolutely horrific self own, depleting the US of amazing students from all over the world who contributed to what used to make America great: its diversity, its openness, and its leadership in education.

The number of international students arriving in the U.S. in August fell by 19% this year compared with last year — the largest decline on record outside of the pandemic.

The data shows the steepest decline in August international student arrivals since the pandemic.

More broadly I wonder about the support for the claim: "While many variants are similar in their ancestry-specific allele frequency estimates, many are also highly divergent". What is the evidence that rare alleles are highly divergent in frequency among groups?
gcbias.bsky.social
Eg a variant at 3/10000 in Eur vs 1/10000 Afr ancestry would be put in this box. Looking at raw counts seems suspectible to sampling noise especially for rare alleles. Obviously there is drift between groups but FST is low (~0.1) so differentiation is low.

Re. the claim that ~80% of variants show "twofold difference in ancestry-specific frequencies", given that many of these variants are rare I wonder how informative this statistic is?

New paper by former MSc student @christeinecke.bsky.social! ⭐ A behemoth effort to apply artificial selection on clonal reproduction in #Mimulus guttatus. We show that clonality evolves quickly, but not symmetrically in both directions, and multivariate life history traits are altered too! 🧪🌾

I have been trying to get this published as an op-ed, but I am going to post it here since I think it is timely in light of the "consent" extortion events.

The AAUP and other labor groups sue the administration over its plan to charge $100,000 for every new H-1B. The AAU is not party to the suit, even though though its members among the largest employers of foreign academics. We’re seeing which groups are willing to let others take the heat.

The surprise policy rolled out last month could cause “catastrophic setbacks” to research in the U.S., the lawsuit alleges.

Cheered out of feeling a little sad today by finding that our departmental office has started its bowl of halloween candy on its front desk. Amazing what a free reeses peanut pumpkin can do for ones' mood.

Population Biology Modeling & Theory (PBMT) is a peer-reviewed journal reporting advances in modeling and theory within population biology. Its scope spans demography, ecology, epidemiology, evolutionary biology, population genetics, and phylogenetics. PBMT will be online soon.
