Exhilarated to share a 2nd @science.org cover article this month from our lab @ucberkeleyofficial.bsky.social! A collaboration with US & Mexico colleagues on the role of a Mexican biogeographic holding pen in shaping the Great American Biotic Interchange (GABI)(1/11) www.science.org/doi/10.1126/...

I especially love this diagram.

Glad to share our new study at @natcomms.nature.com which resulted from several workshops on the early warning signs of mass extinctions and coordination of macroevolutionary vulnerability and the states of carbon cycle and temperatures. www.nature.com/articles/s41... 🧪⚒️ #Geology #Paleobio #EvoBio

Drought and trajectory to forest dieback in CH: since weeks it is too dry in many places - various villages in Fricktal (www.fricktal.info/news/gemeind...) have measures to ration drinking water. The question remains if the trees will survive - brown leaves that early in August is not a good sign.

"Is this jargon?" 🤔 We put together a simple decision tree to help think through when specialized language makes communication clearer, and when it gets in the way. Less about finding the "right" answer and more about thinking differently. Think we missed a branch? Comment below 👇 #SciComm

Insect decline usually focuses on species we can name. But "dark taxa" like true flies kept revealing new species over 37-years of sampling a German stream, while well-studied mayflies/stoneflies/caddisflies plateaued with far fewer individuals. doi.org/10.1111/icad... @swarmofthoughts.bsky.social

1. A bit of evolutionary biology. I'm really intrigued by a new perspective piece from Steve Frank that explores connections between how natural selection creates systems that generalize and recent work in machine learning about the surprising capabilities of massively overparameterized systems.

Abstract. Natural selection encodes learned information in the genome. Learned solutions may be tuned specifically to past challenges, failing in altered e
