New paper out in Oikos (2025)!
Cities reshape selection on carotenoid-based, plumage colouration, in 2 related bird species
The widespread urban paleness of carotenoid-based plumage colouration might be driven by natural selection!

Our paper getting a nod from @carlbergstrom.com for best-practice on our data viz approach! 👀🔥
Glad the efforts on building these graphs are recognizd 🕺

Flagging this both because it's cool research, and because the graphs shown here illustrate a very important best-practice of showing both the curves/confidence intervals and the raw data points themselves whenever possible.
