Now out! How important is social experience in male mating behavior? @corrallopeza.bsky.social found that experienced males were more likely to coerce non-receptive females, but did not change overall preference onlinelibrary.wiley.com/doi/10.1002/... w/ @vdbijl.bsky.social @idarolti.bsky.social

Please help! We are looking for tissue-specific RNA-seq datasets or pubs with both male and female individual gene expression data, not pooled, from animal species. If you know of any relevant resources, please drop a link in the comments or send me a DM. Also, please help spread the word - thanks!

#rstats It is with profound sadness I heard that my long-time friend and colleague, John Fox passed away this week. He was the author of {car}, {effects}, {Rcmdr}, ... and numerous influential books. I will miss him greatly. www.john-fox.ca

Team fish - we need your help! We are trying to build a database of all the fish chromosome-scale genomes where sex chromosomes have been identified. Have you build one or some? Do you know someone who has? Can you post the link in the comments? Please spread the word and repost! Thank you!

Join us! 🧬🪰🎉🔬 We are currently advertising two #PhD projects to study the #evolution, #development and #genomics of sexual traits in stalk-eyed flies. Deadline for applying is Wednesday, January 7, 2026. Get in touch for more info!

So Google Scholar now links to an.. 18+ website to read my latest @natecoevo.nature.com paper. 🤔 It does include some guppy mating behavior.. but this seems like an overreaction.

NEW: Common Crawl, the massive archiver of the web, has gotten cozy with AI companies and is providing paywalled articles for training data. They’re also lying to publishers who have asked for material to be removed. “The robots are people too,” CC’s exec director told us when we asked about this.

Did you publish part of your PhD work in Evolution or Evolution Letters this year? You may be eligible for this award! Papers must have been included in a 2025 issue to be eligible. Apply by January 30: shorturl.at/CnVo6 @journal-evo.bsky.social @evolletters.bsky.social

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...

Wanted to look at the review history of a JEB paper from a mere two years ago - but hosted on publons so gone forever?

Our paper on the genetics of guppy color patterns has now been assigned an issue in NEE: doi.org/10.1038/s415... With this paper, we also publish all 14,100 guppy photos used in the study, including before and after alignment and ornament extraction: doi.org/10.20383/103...

Many of us are using LLMs in coding and scientific writing. They are very helpful tools, but we need to be thoughtful as we integrate them into our work flows to preserve accountability, voice and trust. academic.oup.com/evlett/advan.... An editorial at @evolletters.bsky.social for discussion:

ESEB Day 3! Molecular clocks & identifying ghost lineages; marrying micro & macro evolution; female polymorphism; balancing selection in round-nose grenadier; the genetics of guppy colour polymorphisms; modelling genetic interactions; antagonist selection in flying ants #eseb2025 #eseb #sciart

Just in time for her #eseb2025 poster on Thursday, @squarehare.bsky.social 's paper on the Poecilia bifurca sex chromosomes was published today academic.oup.com/g3journal/ad...

I hate conference apps with a passion.

I’m really sorry to be missing #eseb2025, but for those sorting out their conference plan there are several lab talks and posters about what we are up to. Spoiler, they aren't all talking about guppies, or even fish! 1/n

‪A really lovely commentary on @vdbijl.bsky.social's paper by Nidal Karagic and Claudius Kratochwil in @natecoevo.nature.com www.nature.com/articles/s41...

Guppy colouration is a very diverse trait under natural and sexual selection. Using a combination of high-resolution phenotyping and genomic analysis, the authors reveal the genetic architecture of this complex trait www.nature.com/articles/s41...

This is amazing work and a great thread, revealing the hidden genetic complexity behind the equally complex pigmentation patterns. Check it out! 🧪

🚨 Super exited to see our paper on the inheritance and genetic basis of guppy color variation come out in @natecoevo.nature.com‬ rdcu.be/eugWV Guppy males have enormous variation in color patterns, with many combinations of ornamental spots and stripes. But where does all this variation come from?

Go check out @jacejostles.bsky.social 's very pretty poster this evening about the science behind guppy magic and science communication. Spot I1 #evol2025

🚨Postdoc opportunity🚨: LepEU postdoc: comparative population genomics of European scale adaptation in butterflies 2 year, full-time PD in my group, Stockholm Univ. Applications assed on rolling basis, deadline: 23 August 2025. Planned start 1 Oct. Details: christopherwheatlab.wordpress.com

I'll be at #Evol2025, and would love to talk if you have submission ideas for the journal!!

Am looking forward to being back in Athens for #Evol2025! Come see me talk about @vdbijl.bsky.social 's beautiful work on beautiful guppy colours on Saturday, 11:15 in the Athens GH. www.biorxiv.org/content/10.1...

Reading a paper in ProcB that declares AI use as: “We have used AI-assisted technology in creating this article”. What’s the point of including such an unspecified declaration? It seems equivalent to declaring “we have competing interests” but not declaring what they are.

Interested in a PhD connecting sensory ecology and evolutionary genetics? Applications are now open for a project on the Speciation Genomics of Eye Size Variation in Heliconius Butterflies in our lab at LMU Munich: www.evol.bio.lmu.de/research/mer... Please repost!

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

We are looking for new manager for our computing unit! If you have experience in both biology and computers, this might be the perfect job for you! UBC is a lovely place, and Zoology is a fantastic, collaborative and kind department. Apply by May 4th at ubc.wd10.myworkdayjobs.com/ubcstaffjobs...

There should be no question about this!

Hiding in plain sight: the Y chromosome and its reinvigorated role in evolutionary processes doi.org/10.1093/evle... Now in @evolletters.bsky.social by Wouter van der Bijl and @judithmank.bsky.social. 📷: Jacelyn Shu

Thank you, @eseb.bsky.social!

hi i'm new here but here's a poster i made featuring research by yuying lin and @judithmank.bsky.social!! i presented it at @evolmtg.bsky.social last year and the goal was journal cover meets back-of-napkin scribble meets "you know every science poster ever, yeah not that"

Recent studies have revealed unexpected Y chromosome diversity and suggest that the Y may play a big role in evolution. @vdbijl.bsky.social and I wrote this perspective for @evolletters.bsky.social with a few suggestions and requests. academic.oup.com/evlett/advan... Figs by www.jacelyndesigns.com

Canada's Environment Minister Steven Guilbeault is under attack for suggesting that adding more roads just induces demand. He calls for more transit and active transport. And the country goes wild, calling it "the slippery slope to climate tyranny." The hard truth is that he's right.

The gene cortex has been thought to control butterfly and moth wing colour. Now *three* preprints challenge that view, claiming that two types of regulatory RNA next to cortex might be the causal mechanisms.
