📰 Starting this friday with some positive news: Our publication "Pangenomes as a framework for adaptive radiation, speciation, and adaptation" came out today in the American Journal of Botany! bsapubs.onlinelibrary.wiley.com/journal/1537...

I have a new preprint demonstrating a genome-architecture-aware approach to inferring species trees and introgression landscapes from a small number of genomes. If you are interested in phylogenomics, birds, or hybridization, this is for you! www.biorxiv.org/content/10.1...

I mean, the title says it all: Genetic confirmation of an “uncommon mourningthroat” (Geothlypis philadelphia  ×  G. trichas): A rare but persistent hybrid warbler. Fun stuff with @kevinfpbennett.bsky.social and Kurt Gielow, OA in @wilsonornithsoc.bsky.social! 🦉 🧪 www.tandfonline.com/doi/full/10....

Changing Views on Speciation onlinelibrary.wiley.com/doi/10.1111/...

Our new @science.org paper is out! Cuckoos and hosts are locked in a coevolutionary arms race over egg mimicry. But how are these egg types inherited, and could this drive speciation? We sequenced hundreds of genomes to find out! doi.org/10.1126/scie... 🧵1/6

Happy to see my former @nbis.se advisory program student Zach Nolen's new pipeline PopGLen for analyses of short-read data using genotype-likelihood based methods out! Github: github.com/zjnolen/PopG... Paper: academic.oup.com/bioinformati...

New review out! With students in my lab, we explore how population size shapes speciation—from drift in small populations to selection in large ones. Do small or large populations speciate faster? The answer is more nuanced than you might think. esj-journals.onlinelibrary.wiley.com/doi/full/10....

The first Aguillon Lab paper is officially out in early view at Evolution!! Led by postdoc @devonderaad.bsky.social, we’ve explored the hybrid zone between black-headed and rose-breasted grosbeaks in the Great Plains. #ornithology #hybridization #speciation #evolution doi.org/10.1093/evol...

Just published: Conservation genomics of two endangered buntings reveal genetic diversity before and after severe population declines. doi.org/10.1186/s129... Despite severe population declines, both species retained high genetic diversity but experienced increased inbreeding. #ornithology #birds

We have a new paper out in Molecular Ecology, led by @devinbendixsen.bsky.social ! Reproductive isolation due to divergent ecological selection is accompanied by vast genomic instability in experimentally evolved yeast populations onlinelibrary.wiley.com/doi/10.1111/...

Heads up: ignore samtools dot org, similarly minimap2 dot com and likely others. It's owned by a known phishing site and while the binaries they offer look valid currently (but note they may be serving us different binaries to others), that could change. Ie: it's not us (Samtools team)! Be warned

I am beyond excited to announce that ggplot2 4.0.0 has just landed on CRAN. It's not every day we have a new major #ggplot2 release but it is a fitting 18 year birthday present for the package. Get an overview of the release in this blog post and be on the lookout for more in-depth posts #rstats

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

The paper for my R package is published! This has been a fun process learning more about hybrid zones and triangle plots. Thanks everyone who has contributed and tested it out already! www.nature.com/articles/s41...

New rock dove paper!🕊️ Bit by bit, we are disentangling their evolutionary history and adding evidence to recognise the elusive West African rock doves as a different species *please ignore the little typo in the title, livia should be lowercase @trstngnthr.bsky.social doi.org/10.1002/ece3...

My very first post on here. I am stoked to share lab's latest paper led by @ethantolman.bsky.social. Ethan developed a highly scalable pipeline to differentiate between various gene flow models, including ghost introgression in phylogenomic datasets. Check it out! www.biorxiv.org/content/10.1...

If you're at #ESEB2025 drop by my poster today and let's chat about Birds-of-Paradise and their potential ring-like speciation history!

Our genetic kinship estimation tool “DeepKin” is now available! Our neural network models trained on simulated data work effectively on real ancient data from diverse backgrounds and often outperform available tools. @compevohumang.bsky.social onlinelibrary.wiley.com/doi/10.1111/...

Thanks a lot @jenteo.bsky.social for discussing our paper on your blog!

For folks interested in hybrid zones / introgression / speciation, this looks interesting: doi.org/10.1101/2025...

Very excited to have our study come out looking at multiple plant mosaic hybrid zones and their implications for hybrids to act as "sutures" of species ranges. We use genomic data to project shifts into future climates and discuss impacts on conservation/management. www.pnas.org/doi/10.1073/...

Very happy to share a new paper open access in Syst Biol. Introgression is commonly reported in phylogenomic studies, but whether these patterns are caused by ancestral or contemporary gene flow is rarely understood. Here we took a stab at this problem using parapatric tinkerbirds as a model (1/10)

happy to see our study on genetic parallelism of reproductive isolation in chickadee hybrid zones out in @evolletters.bsky.social—great work led by Georgy Semenov & Scott Taylor: doi.org/10.1093/evle...

Now published! We examine how female competition shapes movement ecology. We provide the first genetic evidence of female philopatry and male-biased dispersal in a socially polyandrous bird species! doi.org/10.1093/evol... @journal-evo.bsky.social

Remember when you first learned about genetics at school? All those fascinating examples of human traits that are each apparently determined by just a single gene? Time to check in on some of your favourites to see how they’re doing. 🧬🧵🧪 1/n

A complete and dynamic tree of birds - out today in PNAS! Teamwork with @eliotmiller.bsky.social and others at @birdsoftheworld.bsky.social and Open Tree of Life to put together current relationships across all birds. www.pnas.org/doi/10.1073/...

More good news this month! 🎉 I'm excited to share my PhD colleague Filip Thörn's fantastic study on hybridisation in lek-mating Birds-of-Paradise, which I had the privilege to be part of. 🐦 doi.org/10.1111/mec.... #museomics #genomics #hybridisation

A little tutorial to make interactive maps with GBIF data for any species, including any metadata you want - pictures too Great work by intern Edgar Signe from Brest University www.montejo-kovacevich-lab.com/projects/

I finally read @s-m-aguillon.bsky.social 's NEE paper on allllll the reproductive barriers in swordtails, and loved it. We bumped our lab meeting discussing it to next week because we all want to take more time on it. Definitely a paper to teach speciation from. www.nature.com/articles/s41...

Excited to see my third thesis chapter published! We used #museomics to investigate hybridisation in New Guinean honeyeaters 🐦 and found that two lineages likely fused back into one after initial divergence. 🔎🧬 Huge thanks to all collaborators who made this possible! doi.org/10.1111/mec....

New paper out in Ecology Letters (open access): I and Daniel Matute consider 'species sorting' -- a bias in the outcome of secondary contact following the allopatric stage of speciation -- as a reason for the much-observed pattern of elevated trait differences in sympatric close relatives

With @hybridzones.bsky.social & @jenncoughlan.bsky.social, we have been working on an update to Daven Presgraves' influential 2010 review on hybrid incompatibilities (shorturl.at/cJndf). The preprint is available here (shorturl.at/DTC48) with an updated table of almost 100 incompatibilities!

This needs to be shared and shared.

Not really my announcement to make--I am but a lesser co-author--but IQ-TREE 3 has just been released! (Most credit to Minh Bui and @roblanfear.bsky.social and their labs) ecoevorxiv.org/repository/v...
