Cryptic female choice can maintain reproductive isolation Abstract. Sexual selection has long been considered an important mechanism of speciation. Despite growing empirical evidence that postmating sexual selecti

My latest paper, Cryptic female choice can maintain reproductive isolation, with @servedio.bsky.social and Suzanne Alonzo is now out in the October issue of @journal-evo.bsky.social ! (1/3)

Sexual selection and speciation: a meta-analysis of comparative studies Abstract. Understanding the drivers of biodiversity is a central goal in evolutionary biology. In particular, sexual selection has long been proposed as a

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.

This is a really interesting story. Microsporidia have genome architecture as no other creatures! Congrats @amjadkhalaf.bsky.social

I'm very happy to share that our paper describing the evolution of sex chromosomes in brown algae is out!🎉 This project was a long journey, but it came together into a nice story 🧬 🌊 Grateful to everyone who helped along the way!

Family photo of the 2025 Workshop of the @treeofsex.bsky.social ! Thanks everyone for attending and see you soon!

Great work by @aruizherrera.bsky.social's lab! Amazing paper and have you see the graphical abstract? Happy reading!

This is insane! The Atlas blue butterfly has 227 pairs of autosomes and four sex chromosomes, the highest recorded chromosome number in non-polyploid Metazoa!!!! See below!🦋

Hot from the press: XX/XY sex determination in Nautilus (unique among cephalopods)!!!! 🐙

The day 2 of the #TreeOfSex annual workshop started with a great talk by @yannguiguen.bsky.social about B chromosomes and their role in sex determination in fish. Next up, Sònia Garcia is giving an update on the works of the Literature team.

Right now we are working on sorting the most important definitions in our Ontology TOSO. If you would like to join the discussion reach out or check: github.com/Tree-of-Sex/...

Tree of Sex annual workshop started today. It will be two days packed with reproductive biology.

Thank you for the interest. Worth noticing that we are an open consortium, you can register/join at our webpage and shape the way we catalogue knowledge 🦈

Good to see some of our US-based ToS members at #Evol2025! If you're at the meeting and interested or just curious about the project, say hi to @ajmongue.bsky.social @nicolevalenzuela.bsky.social @ideaspermatheca.bsky.social @emistasis.bsky.social, Mike White or Louise Heitzmann!

Officially (re-)annoucing the Tree of Sex! Read all about it in JEB below!

As work ramps up, we've created a Starter pack to follow members of the consortium.

Hi folks, this is the official Tree of Sex account. We are an open consortium of reproductive scientists with the aim to catalogue reproductive knowledge across Eukaryota. You can be part of it too: treeofsex.sanger.ac.uk

The @treeofsex.bsky.social is working on this! 🤞🏽
