impressive thesis, amazing defense talk and utterly gorgeous hat! huge, huge congratulations, Matteo, fly on! it was a pleasure having had you with us @ifv-whv.bsky.social 🪶🪺🐦🧬
awesome work by @junishigohoka.bsky.social highlighting the underappreciated role of shifting balancing selection. jun used demography inference, pogen simulation under our blackcap demography, and ABC to (i) identify the type of balancing selection and (ii) estimate its spatially varying parameters
The Banter See breeding season in numbers so far: 226 males and 210 females (aged 2 - 25) have been registered, 319 clutches have been produced, 257 chicks have hatched, 93 blood samples have been collected and 48 birds have been caught for our geolocator-project.
Hatching has started at @gullbilledterns-de.bsky.social's colony site too. ❤️

Migratory birds perform extraordinary journeys—but we still don’t fully understand how they do it. #TiiaKärkkäinen, @pablosalmon.bsky.social & @barbarahelm.bsky.social reveal why the field of migration physiology is still wide open for new discoveries

Huge congratulations to @matteobeccardi.bsky.social on successfully defending his PhD thesis "Intrinsic and extrinsic factors shaping individual quality in birds"!!!🐦🥚🐣🤔🎓 🎉
Cheers to the next chapter!!!🍾🍾🍾
The 2-year-olds have started to arrive en masse and, with 83, now make up 18% of the registered birds at the colony. At 470 of those, we are exactly 70 above the number we had this time last year. Food is looking good too, and the chicks are growing nicely. ❤️
Fresh as can be. Hatching has started at the Banter See common tern colony. ❤️
Excited to celebrate the opening of the Kids4Kids Mobile Exhibition on Bird Migration with @genmig.bsky.social ! 🐦🎙
A project where children communicate science to their peers through podcasts, interactive exhibits, and a VR journey following a robin's migration.🌍✨

Paper alert!🧬🐦💻
Divergent selection is the textbook explanation for narrow inversion clines.
Our blackcap inversion cline doesn't fit: it is wide, and the inversion is always the rarer arrangement. We show that negative frequency-dependent selection shifting between populations underlies this!

We investigated what factor contributes to a cline of a chromosomal inversion of the Eurasian blackcap, which differs from typical inversion clines maintained by divergent selection. Using a simulati...
