Experimental test of the fitness effects of divergent marine–freshwater chromosomal inversions in stickleback under different salinity conditions - Heredity Heredity - Experimental test of the fitness effects of divergent marine–freshwater chromosomal inversions in stickleback under different salinity conditions

Really excited to share my first PhD paper about fitness effects of chromosomal inversions!

Using an experimental approach we explored if inversions involved in ecotype divergence in threespine stickleback affect fitness-proxies 1/🧵

North American bird declines are driven by reductions in common species Declines in North American birds are driven not by rare species vanishing but by sharp losses among formerly common species.

🚨 First PhD chapter is out! My work thus far, with @andy2dobson.bsky.social

We found that formerly common species have declined the fastest, on average.

Coming soon! A mid-summer special BOW Discovery Webinar on AVILIST - the world's first unified global checklist of birds. Does this sound good? Would you like to join us?

Stay tuned for more info. Target is late July. We'll do our best to make this during a globally friendly timeslot.

The biggest "meta-analysis" ever? - 17 million effect sizes - elifesciences.org/articles/95857

With wonderful @coreytcallaghan.bsky.social and Will Cornwell

We question the abundance-occupancy relationships using ebird data - we find ~ zero correlation

Millions of birds nest in the Arctic each year. But did you know they’ve been doing this since the Cretaceous? Can’t believe I finally get to share that our paper on the birds of the Prince Creek Formation is out in ‪@science.org (and on the cover)! 🧵
