Oxygen supersaturation has been reported to protect aquatic animals from heat waves. We tested this in a large collaborative experiment on many species of fish and crustaceans. Our new paper in @plosbiology.org shows that the effect of hyperoxia on thermal tolerance is negligible. Unfortunately.

High temperatures amplify aggressiveness of an invasive lizard toward a native congener Invasive species cause major disturbances to endemic wildlife and often displace native species. Behavioral aggression can contribute to invasive spec…

New paper! PhD student Julie Rej found that invasive brown anoles are more aggressive than native green anoles across a wide range of temperatures. The difference is greatest when it's hottest, ie, heat amplifies the aggression of an invasive species!

Picture of a lizard attached to a pencil with text saying that researchers have found that lizards in New Orleans are so full of lead you can write with them

Some more nice coverage of the lead work

These lizards can survive (and thrive) on a lethal dose of lead Small lizards in New Orleans have an “unprecedented” tolerance for the toxic heavy metal. How are they even alive?

Lizards in New Orleans have highest blood-lead levels ever recorded, study finds Brown lizards in New Orleans carry more lead in their blood than any other animal on record — levels that would kill humans — yet they seem unfazed, according to new Tulane study.

Early view: we find that brown anole lizards are one of, if not the most, lead tolerant vertebrates known to science combining measures of field exposure, responses to lab dosing, performance assays and functional genomics. Led by PhD student Annelise Blanchette

Cover of the journal "Nature" showing a long-nosed horned frog on leaf litter and the words "Heat Stress: How vulnerable are the worlds amphibians to rising temperatures?"

We made the cover

Done

Thanks!

New paper in @nature.com led by @patricepottier.bsky.social! We demonstrated global vulnerability of amphibians to warming, threatening 10% of >5,000 species examined. How did we do it? See thread🧵

Paper: www.nature.com/articles/s41...

Happy to see this out and congrats in particular to @patricepottier.bsky.social after leading such a huge effort! I think there are some really interesting findings here that challenge common ideas about the geography of warming risk and how we measure it

Evolution of temperature preference in flies of the genus Drosophila - Nature A study using flies of the genus Drosophila adapted to life in diverse thermal environments shows how evolution has shaped temperature preference by acting on both molecular heat receptors and thermosensory circuits in the flies.

Map of the United States displaying hydrogen ion wet deposition levels from measurements taken in 1985 by the Central Analytical Laboratory. The map uses a color gradient from green (low deposition) to red (high deposition) to show varying levels of H+ deposition (kg/ha). The highest deposition levels are concentrated in the northeastern U.S., while the western U.S. has the lowest levels. Black dots indicate measurement locations. The map is sourced from the National Atmospheric Deposition Program/National Trends Network

Map showing hydrogen ion wet deposition measurements across the United States and parts of Canada, indicating values in kg/ha for 2022. The color gradient represents different concentration levels, with a scale on the right. Sites not pictured are listed at the bottom. The map is mostly green, indicating that H+ deposition is no longer a environment issue that it once was.

Another dataset I like is from the National Atmospheric Deposition Program, which has maps of the US that show we fixed the acid rain problem by implementing stricter emission controls on power plants.

In case folks are interested in contacting their congresspeople about the NIH indirect cuts with some estimates of what they would mean for institutions in their state, here are some estimates based on published F&A rates and funding ... let me know if you want a particular state

SICB is back! Please follow the society's new BlueSky account: @sicb.bsky.social SICB recognizes that the scientific enterprise is only successful because of the people performing that science. Without those people, science and all of the political and economic strength that it provides, stops.

Louisiana folks - Sen. Cassidy may be wavering on RFKj.

Cassidy's office number in DC is (202) 224-5824 if you want to let him know what you think about that nomination.

Heat sensitivity of sperm in the lizard Anolis sagrei Summary: Investigation of gamete heat sensitivity reveals heat tolerance and repeatability in lizard sperm. These findings are essential for understanding reproductive responses to climate change.

As someone who has reported on AI for 7 years and covered China tech as well, I think the biggest lesson to be drawn from DeepSeek is the huge cracks it illustrates with the current dominant paradigm of AI development. A long thread. 1/

If you're a scientist that serves on an NSF panel that got cancelled today, I'd love to talk to you about it for an NPR story. DM, email or reach out on signal.

Stress responsiveness in a wild primate predicts survival across an extreme El Niño drought White-faced capuchins with a stronger stress response to previous droughts were more likely to survive a severe El Niño drought.
