Weird sperm of the red-browed finch take the cover of @jevbio.bsky.social this month.

📣 Read our latest issue! 📘 academic.oup.com/jeb/issue/39/4 📸 Red-browed Finch (Neochmia temporalis temporalis), an Australian songbird with highly atypical sperm morphology. Most passerines have elongated, corkscrew-shaped sperm, this subspecies has 'tadpole-like' sperm. Photo Credit: Des Boorman

Sperm can “age” independently of the male, when stored in male or female reproductive tracts. Our meta-analysis finds widespread evidence across animals (including abstinence in men). Important consequences for fertility, sexual selection, haploid selection! doi.org/10.1098/rspb...

What do milk, seminal fluid, eggs, and regurgitates have in common? Find out during our Focus Session at NWO Life 2026 “Socially Transferred Materials: Connecting Physiology, Ecology & Evolution” (28-29 May 2026, Egmond aan Zee, NL) 🐜 🐸 🐌 🐄🥚 @socialtransfernet.bsky.social

Abstract submission may be closed, but it is not too late to sign up to attend the NLSEB Annual meeting. Great plenary talks and a great line up of talks and posters. And thanks to our sponsors NWO and @isme-microbes.bsky.social for helping making this meeting possible.

Don’t miss out. If you are in the Netherlands and consider yourself an evolutionary biologist then this is a must attend event!

I am proud to present our recent #neuroethology paper on #magnetoreception in #ants today on the #InternationalDayofWomenandGirlsinScience where all authors are #WomenInSTEM @chiaratenne.bsky.social 🤩👩‍🔬🧪🧠🐜🧭 Thanks to @sfb1372.bsky.social for featuring our research in a video 🤩 doi.org/10.1007/s003...

📣SUBMISSION DEADLINE APPROACHING: 📣 28th February Special Issue: Foundations of Internal Conflicts Guest Edited by @martijnschenkel.bsky.social, @arvidagren.bsky.social, @imprintedgene.bsky.social, Nina Wedell and Manus Patten For more info: academic.oup.com/jeb/pages/ca...

Heat can make #fruitfly males sterile at temperatures below their lethal limits. We explore if tissue-specific heat shock protein expression can explain why using 6 #Drosophila species: @chsmithson.bsky.social et al. @ejduncan.bsky.social @amandabretman.bsky.social doi.org/10.1093/jeb/...

Special Feature: Can we predict the future of evolution? In this review, Jackson et al. dig into genomic analyses of change over time to determine if and when evolution can be forecast using genomic methods. Read now ahead of print! www.journals.uchicago.edu/doi/10.1086/...

Great to have @alexfig.bsky.social joining the team to work on reproductive microbiomes in house sparrows

Grateful for received #funding from @koneensaatio.fi for our project on impact of light pollution on the flux of insects between aquatic and terrestrial habitats. Will be looking for a #postdoc and a #PhD for 4 years – take contact if interested. koneensaatio.fi/apurahat-ja-...

Congratulations to Yuting Dong and co-authors on another publication from Yuting's PD thesis. High temperatures have negative impacts on spiderling growth and survival. www.sciencedirect.com/science/arti...

Out now on the cover of @journal-evo.bsky.social! Led by Sarah Khalil, we took a genomic approach to investigate the hybrid zone between different-colored Red-backed Fairywren subspecies. We found some interesting candidate genes under selection. Check it out! academic.oup.com/evolut/advan...

Let’s talk about sperm. Almost all passerine birds have filiform sperm with corkscrew-shaped heads. Not the red-browed finch. This species has highly atypical sperm morphology. Check it out!

Woohoo! Well done STN leads!

Finally we have @dd10mz.bsky.social presenting his work on the colonization of the gut microbiome in offspring during development. He will show the influence of the nest microbial environment on this process. #EOU2025 (3/3)

TODAY!!!!!

hai eseb people ! come to my talk introducing the quantitative genetics of microbiome mediated traits :) 2:30-2:45 at S07.02 btw our ppr just got accepted at evolution ! amazing and challenging reviews ::)) revised pre-print here www.biorxiv.org/content/10.1...

marinamartinmaroto.bsky.social and especially the extensive and impressive PhD work from @jack-harper.bsky.social who sadly isn't here (he's writing up)!

Also, I'm talking at #eseb2025 on the evolutionary history of a commensal species at 2 pm on Monday in S51-02. Come along to hear about how cool house sparrows are and all the exciting work from the sparrow team @melissahrowe.bsky.social @eriksroeed.bsky.social @ruthfawthrop.bsky.social

Interested in host-associated microbiomes? Attending @eseb2025.bsky.social? Then come check out Symposium S07 on Monday August 18th and hear all about how microbiomes contribute to adaptation. Gut microbiomes, climate change, thermal physiology, behaviour, invasion biology, blood-feeding, and more!

We hope many of you will find it useful, and will continue to add data. Here's the preprint: www.biorxiv.org/content/10.1... - hopefully coming soon to a NAR Database Issue near you 😅 Thanks to everyone in the @borklab.bsky.social @embl.org who contributed to this! 7/7
