Anybody know why there are no P monticola (western white pine) data on the ITRDB? There are some older studies (doi.org/10.2307/1934...). Are they just mixed up with sugar pine? @firescar.bsky.social @acsank.bsky.social @rmtrr.bsky.social @thetreecorener.bsky.social

New study provides the evidence for the pervasive presence of cryogenic vacuum distillation artefacts in leaf water and identifies deuterium exchange between organic matter and water as the primary underlying mechanism; @newphyt.bsky.social nph.onlinelibrary.wiley.com/doi/full/10....

You probably heard the US admin is threatening to break up the National Center for Atmospheric Research: but did you know they already froze funding for the 9 regional Climate Science Adaptation Centers? From tracking invasives to helping tribes with drought, here's why the CASCs matter ⬇️

AGU has a Congressional email and call script up on NCAR:

Learned today that “Galápagos” comes from a Spanish word for tortoise, meaning that “Galápagos Tortoise” is, in fact, a tortology

I started getting reports of an unseasonal Joshua tree bloom in the last few weeks, and looking over records on @inaturalist.bsky.social it's pretty widespread! So we're putting out the call for folks to record this "bonus bloom" and help us study it 🌿 lab.jbyoder.org/2025/12/10/w...

Earth's largest land animals are limited by salt. Sodium availability constrains the density and distribution of elephants, giraffes and rhinos across Africa, and offers a new explanation for the so-called 'missing megaherbivores'. www.nature.com/articles/s41... Free access: rdcu.be/eTPY2

If you are a dendrochronologist, you will also find this depressing.

I had missed this article earlier. An example of what we're losing, in terms of science that could make a difference for people in this time of climate crisis. Just one relatively small research group at one university (my own #NorthernArizonaUniversity). Gift link: www.nytimes.com/2025/10/08/c...

Happy Nevada day to all who celebrate. I see some people who have dressed up in spooky costumes. I don't totally understand what this has to do with Nevada, but to each their own.

magnolia trees are pretty cool

The megadrought currently sucking the Southwest dry is having far-reaching impacts on wildlife, especially migratory birds. The elegant trogon is one of them. With arid conditions intensifying, the birds are producing few young, leading to population declines that worry researchers. 🌎

Cool piece, highlighting some of the impacts of the recent wildfires on the North Rim of the Grand Canyon, as well as impacts of shutdown in slowing recovery.

With the AWS outage, now‘s as good a time as any to post this old strip.

Join the Laughlin lab and our new NSF funded project! Awesome opportunity to visit forests across the western US and examine the functional basis of demographic responses to drought and wildfire.

Thank you to the @lasvegassun.bsky.social and reporter @hillarylvsun.bsky.social for a terrific story on research into underground ecosystems that could inform the search for life beyond Earth. Read the story: bit.ly/drinasa #NSHE #NASA #DiscoverDRI #UNLV #UNR

Chunk, a 1,200-pound behemoth with a broken jaw, swept the competition Tuesday in the popular Fat Bear Week contest — his first win after finishing in second place three previous years.

It's possible I will recruit a PhD student this year: If you are interested in tree physiological ecology, Bayesian modelling, carbohydrates, hydraulics, or desert/arid ecology please email with a description of your experience. Application deadline December 15. www.unlv.edu/graduatecoll... 🌏

1st pub from Phd student Alicia Formanack synthesizing tree ring widths in drought-killed trees to show that, nope, there are no universal patterns. We present a framework combining previously described syndromes: flashy, decoupled, or declining?🌏🌐 doi.org/10.1111/nph.... @newphyt.bsky.social

Really enjoyable. Many good one-liners, but my favorite: "​AI-made material is itself a waste product: flimsy, shoddy, disposable, a single-use plastic of the mind." www.nplusonemag.com/issue-51/the...

Despite broad political support, one third of the nation's Climate Adaptation Science Centers will wind down in coming days due to lack of funds. The Northeast, South Central, and Pacific Islands will be left without actionable science on drought, floods, wildfire, sea level rise and other hazards.

New paper led by PhD student Elise Pletcher! Forecasts from simple, density-dependent population models are highly transferable to new sites. Adding env. covariates does little to improve prediction in-sample and worsens forecasts out-of-sample. besjournals.onlinelibrary.wiley.com/doi/10.1111/...

Our comment on the DOE CWG report is done. It tips the scales at 439 pages, approx. 3x longer than the DOE report. This is related to Brandolini's law: The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it. Example: refuting one sentence.

Three of nine regional Climate Adaptation Science Centers (CASCs) across the country will shut down by October if OMB continues to withhold funds to renew their 5-year cooperative agreements - which includes funds already appropriated to the CASCs by Congress for Fiscal Year 2025.

Our "Joshua tree is CAM" paper is finally out: nph.onlinelibrary.wiley.com/doi/10.1111/... Data collection started back in 2021, when we saw weird results in some RNAseq that made me stop and wonder if Joshua trees, long thought to be C3, were actually...CAM!
