Our work on the generalizability of polygenic scores (PGS) from the @arbelharpak.bsky.social Lab is now officially out!
We examine the accuracy of PGS predictions at the individual level. We make 3 observations that expose gaps in our understanding of PGS “portability.”

What happens *after* enemy release? In a new paper, we present 7 years of infection & immune trait dynamics in 16 lake populations of stickleback.

This is definitely the longest-scale study I've done in my career, I'm very excited to see it out.

description from Huntington library: "A lithograph printed on heavy paper. Satirical "death certificate" issued for the Southern Confederacy. Mourning border, each line in different typeface, with: Died, Near the South-Side Rail Road, / on Sunday, April 9th, 1865, / The Southern Confederacy, / Aged Four Years, / Conceived in Sin, Born in iniquity, Nurtured by Tyranny, Died of / a Chronic Attack of Punch. / Abraham Lincoln, Attending Physician. / U.S. Grant, Undertaker. / Jeff Davis, Chief Mourner. Below in smaller print an epitaph that ends with: And this one line shall grace your grave-- / Your death gave freedom to the slave." https://hdl.huntington.org/digital/collection/p16003coll6/id/5033

Wild mice show large, robust T‑cell receptor repertoires that stay broad across age and sex, while older mice develop more dominant clones, likely from lifelong pathogen exposure. A fascinating look at how immunity adapts in natural environments.

New preprint from the fantastic @sarah-dobson.bsky.social !!
Worried about assuming causality when estimating selection? Confused about knowing whether selection is hard or soft? We have the solution for you!

Excited to share the latest preprint from the lab "Fluctuating environments are sufficient to drive substantial variability in species abundance across locations" now up on arXiv arxiv.org/abs/2603.02403 🎉
Leipzig U and the MPI for Evolutionary Anthropology (MPI-EVA) have an open faculty position (W2) in evolutionary population genetics! This position is tenured and comes with generous core funding. We are eager to welcome a new colleague! Deadline March 11.

Waking up in the dark, routinely, day after day, is incredibly, *incredibly* bad for you (people who work night shifts for years on end have health outcomes similar to moderate smokers). Under permanent DST, sunrise in Seattle would be after 8am for 3.5 months a year.

Have you ever wondered 🤔... Does phenotypic variance respond to environmental perturbation? Does it have a genetic basis? Are mean and variance regulating loci exposed to different selection pressures? These and more questions are explored in our new preprint 🔥

I am hiring a research assistant (vampire bats), a Panama fieldwork coordinator (vampire bats), and also considering postdoc apps (social behavior, any species): socialbat.org/2026/02/19/h...
Just over a week left to apply for this PhD project (unfortunately UK students only). If you're interested then please get in touch!
So happy to have been part of the ARTEMIS Programme last year! Check out this piece to see Imma Mungai and me, plus a brief overview of the programme.
The new call is open, if you’re a scientist at an MPI, it’s a lovely opportunity! 👇

🧪Before the day begins, meerkats share a unique ritual. After emerging from their burrows, they spend up to an hour "sunning" to warm up for the day. During this quiet time, they produce soft, tonal "sunning calls". Just standing, sunbathing, and calling. But why❓ #bioacoustics #meerkats #kalahari
Looking for a postdoc to work with existing SNP data from parasites of guppies across Trinidad. How do river structure, host specialisation, and host behaviour structure parasite population genetic structure and evolutionary potential? Join me in Stockholm! Email me :D

Systematic Literature Review figure of how genetic relatedness estimates are done in the wild.
(1/2) The preprint of our perspective on genetic estimates of relatedness in animal populations is out! Big Congratulations to Annika!

A systematic review of 2,861 articles shows that, even in 2025, 75% of such studies use microsatellites. And most use only a few!

GBE | Genome Shows no Recent Inbreeding in Near-Extinction Woolly Rhinoceros Sample Found in Ancient Wolf's Stomach Autopsy of Tumat The autopsy of the Tumat-1 wolf puppy, when a fragment of a woolly rhinoceros tissue was found in the stomach. Coauthors Sergey Fedorov and Mikkel Sinding are shown. Location: Vienna, Austria. Date: 2018. Photo credit: Mietje Germonpré.
Guðjónsdóttir, @jcchacond.bsky.social et al. sequenced the genome of a >14kya old woolly rhino from muscle found inside a permafrost-preserved wolf's stomach. Demographic inference suggests a rapid extinction for the woolly rhino.

Thank you so much @profjudiallen.bsky.social 🤩 Thanks also to #BSI2025 & session organizers including @kathelse.bsky.social 🤩 for a fabulous week of talks & lively discussions!! It was my first BSI but I’ll be back 🤓
***Super cool-project alert***⚠️ Come work with @dirkmetzler.bsky.social and me in trying to understand how transcriptional noise evolves in a phylogenetic context 🧬 Deadline 15th Dec 2025 (Project funded by @dfg.de @gevol.bsky.social)
Excited to introduce the Latent Layers Framework – now out in @behavecol.bsky.social – to help think through when and why network differences confound inference in (comparative) social network analysis! 🧵

I wrote a little bit about the "missing heritability" question and several recent studies that have brought it to a close. A short 🧵
When different kinds of mobile genetic elements get together, they become even more powerful catalysts for microbial evolution! In this work we discovered a mechanism by which Insertion Sequences drive their spread across Plasmids, which helps explain this evolutionary potential!
