πŸͺΊ 🐣 Where do birds end up building their nests? A new study by the KΓΌpper group & colleagues at the University of Oulu shows that in ruffs, this is driven by both social and environmental factors: onlinelibrary.wiley.com/doi/full/10....

What a fantastic Etho 2025 conference in Tutzing this week! 🀩 So much fun as both a speaker (behavioural genetics symposium represent! 🧬) and part of the organising team. It was fantastic connecting with so many brilliant scientists. Already looking forward to the next one!

Super Enzyme Regulates Testosterone Levels In Male Ruffs A single gene in the shorebird species known as ruffs controls the levels of testosterone in males, and this in turn affects their appearance and mating strategies.

A new story about our recent paper came out today in the Science section of Forbes! Check it out! www.forbes.com/sites/grrlsc...

A super enzyme encoded by a supergene. Is there anything not "super" about these birds? 🀩

Studying these male ruffs led to "findings [that] change what we know about how hormone levels can be controlled." That and more of the best from @science.org and science in this edition of #ScienceAdviser: www.science.org/content/arti... πŸ§ͺ

Adaptations in surprising places Testosterone is controlled while it circulates in the bloodstream

A big thank you to @rosvall-lab.bsky.social for the fantastic perspective article on our latest findings! πŸ”₯ The power grid metaphor really captures the essence of our research 🧬
