We started by studying gene reuse in eyes over deep time -- but were astonished to find adaptive molecular convergence to be rampant and not directly related to important traits, including eyes. Led by PD Cory Berger www.biorxiv.org/content/10.6...

New paper out! Limited evidence that butterflies are capable of changing their thermoregulatory performance or thermal tolerance in response to local climatic conditions. Instead, poorer thermoregulators have shown stronger upwards elevational range shifts in response to climate change rdcu.be/fuSJE

Butterflies with low thermoregulatory capacity show greatest upwards range shifts along an elevational gradient

Communications Biology - Lack of variation in thermoregulatory capacity or thermal tolerance in butterflies across an elevational gradient suggests limited adaptive capacity. Poorer...

Ocean acidification emerging as a planetary signal linking today's carbon emissions to Earth's deep-time memory

When most people hear the phrase "ocean acidification," they think of coral reefs, shellfish or declining fisheries. Those concerns are real. But while working on our recent research, I found myself a...

The natural history collections at the University of Texas, holding maybe 5 million specimens, is partly closed down because our buildings are falling apart and UT is doing the bare minimum of life support. We could fix it for 1/5th the price of a vanity purchase of a single dinosaur specimen.

🚨New paper🚨 For decades, it was widely assumed tropical species would be hit hardest by #ClimateChange. Turns out climate-related local #extinctions are already more frequent among temperate species. Read our new study 🧵 @natclimate.nature.com doi.org/10.1038/s415... #BiodiversityLoss #SciSky

Temperate local extinctions from climate change are outpacing tropical extinctions - Nature Climate Change

The authors analyse global-scale resurvey data for 5,151 species to reveal the sensitivity of tropical versus temperate species to climate change. They show significantly higher frequencies of local e...
