A new preprint from my former PhD student Lila Colston-Nepali: “Parallel differentiation extends beyond chromosomal inversions to small genomic islands on a background of rampant gene flow in the European flat oyster Ostrea edulis” www.biorxiv.org/content/10.6... #PopGen #MarEvol #ParallelEvolution

Parallel differentiation extends beyond chromosomal inversions to small genomic islands on a background of rampant gene flow in the European flat oyster (Ostrea edulis)

Heterogeneous genomic landscapes of differentiation can reveal evolutionary processes acting over different timescales. Whereas genetic structure in the European flat oyster, Ostrea edulis , is mainly...

Multi‐Sensor Logger Tracking Reveals the Threats of Offshore Windfarms to Passerine‐Sized Birds

Offshore wind energy is a cornerstone of the transition to renewable energy, yet its rapid expansion raises concerns for wildlife. These concerns notably involve small migratory birds whose movements...

New #ornithology paper out in @ecography.bsky.social! The tendency of birds to return to the same breeding area in different years varies wildly among species. We show that breeding site fidelity is much lower in #shorebirds nesting in the #Arctic tundra than in those nesting in other habitats. 1/n

Our paper is now out! Thanks to @annecharmantier.bsky.social , Samuel, Ségolène, Emilie, Baptiste, the whole zoo team, and the Montpellier tit team 🕊️

🐦🌙 Happy to see this big collaborative paper out in @currentbiology.bsky.social! We address a seemingly simple question using geolocator data collected across many species and individuals: how much of bird migration actually happens at night? www.cell.com/current-biol... A short🧵

🚨 Exciting news! The Swiss Ornithological Institute is starting a collaborative program that offers multi-sensor geolocators and analytical support for bird migration research, focusing on underrepresented species & regions. Interested? geopressure.org/GeoCollabForm/ Please share!

Heading home from Kazakhstan after a very nice field trip: 55 pipits tagged and some extra samples collected for colleagues’ projects (ex Eurasian/Pallid Scops Owls for @pcapi.bsky.social) Many thanks to our colleagues of the Institute of Zoology of Almaty, see you soon! @pdvsky.bsky.social

We stopped for a few days to see @wielandheim.bsky.social & colleagues from the Zoology Institute, who were tagging Himalayan Rubythroats in Almaty. And next in the series of birds outside their breeding range: some Siberian Chiffchaffs, quite a bit farther south than expected. @pdvsky.bsky.social

A nice surprise to find Yellow-browed Warblers (Phylloscopus inornatus) breeding in a relatively small larch forest at ~2,000m elevation in E Kazakhstan, in the same habitat as Hume’s Warbler. As far as we know, the species was not previously known to breed in Kazakhstan. @pdvsky.bsky.social

Some nice and unexpected bycatches from the last days while catching rubythroats: Black-throated Accentor & Water Pipit blackistoni. E Kazakhstan, with @pdvsky.bsky.social

And the star of the show: the Richard’s Pipit (Anthus richardi). We searched for the species along the Russian border, near where the birds that winter in Europe are breeding. Let’s see whether they all go east or west.

Two Siberian Rubythroats (Calliope calliope) from yesterday, E Kazakhstan. Tagged with multi-sensor geolocators for @wielandheim.bsky.social project. w/ @pdvsky.bsky.social

An Eastern Common Nightingale (Luscinia megarhynchos golzii) from yesterday, NE Kazakhstan. What a strange looking bird! w/ @pdvsky.bsky.social
