A Database of Plant Heat Tolerances and Methodological Matters

We collected > 3100 heat tolerance records reported in degrees Celsius, from terrestrial plants encompassing > 1700 taxa, > 1000 genera, and > 200 families from years 1935–2024. Our database is globa...

New publication in @biotropica.bsky.social with former lab members @juan-camilo-mejia.bsky.social and Roxana: onlinelibrary.wiley.com/doi/epdf/10.... We found that net photosynthesis and Vcmax were lower at midday than in the morning, but no evidence of significant changes in leaf heat tolerance

Does branch excision bias our #photosynthesis data? New paper led by #MarcellaCross shows excision increases water potential but reduces photosynthesis in most species, with trait-dependent effects, so excised branches underestimate intact rates. www.researchgate.net/publication/... #MichaletzLab

Episode #237: The Energy Crisis The energy crisis generated by the war in Iran has some historical parallels, including the Suez crisis of 1956 and the Arab-Israeli war in 1973. @adamtooze.bsky.social and Cameron Abadi discuss the similarities and differences: podcasts.apple.com/us/podcast/t...

Què és una “embòlia” vegetal i per què són tan perilloses pels arbres🌳 mediterranis? En situacions de #sequera🌡️, quan falta aigua al sòl, es poden formar bombolles d’aire🫧 (“embòlies”) als conductes transportadors d’aigua💦 de les plantes, una conseqüència que pot ser fatal.

“This is going to be the new normal for Western Canada, so even though this heat dome happened five years ago, I think these results we had in this paper are more relevant than ever,” said UBC botanist Dr. Sean Michaletz. @ubcbotany.bsky.social @seanmichaletz.bsky.social bit.ly/4m2PDKx

Some species benefited from BC's 2021 heat dome — but at an enormous cost, study finds

To paint a picture of how ecosystems changed in the aftermath of the heat dome, scientists used a combination of computer modelling, media reports and a meta-analysis of existing field data and remote...

🚨 New paper out in Journal of Plant Hydraulics! jplanthydro.org/article/view... Our team shows that Optical Dendrometry on small branches produces an incredibly tight linear relationship with water potential (R² ≈ 0.99) during drought‑to‑death drydowns in Eucalyptus crebra.

“The heatwave had widespread ecological effects, including an almost 400% increase in wildfire activity & negatively affecting more than three-quarters of the species studied,” said UBC zoologist Dr. Diane Srivastava. @zoology.ubc.ca @srivastavalab.bsky.social www.ctvnews.ca/climate-and-...

Following the Kent State massacre in May 1970, a Gallup poll showed that 58% of Americans thought the shootings were justified. The night *before* the killings, Ohio's GOP governor described the student protesters this way: "They're the worst type of people that we harbor in America."

It is hard to overstate how critical @ncar-ucar.bsky.social is to climate science in the US and around the world. It's the beating heart of our field. Generations of scientists have trained there, and almost everyone I know relies on deep collaborations with NCAR scientists. It's end is unthinkable.

Exclusive: The Trump administration is moving to dismantle the National Center for Atmospheric Research in Colorado, according to a senior White House official, taking aim at one of the world's leading climate research labs.

The Trump Administration's plan to dismantle the @ncar-ucar.bsky.social is senseless & dangerous. It would weaken weather forecasting, climate research, & the science that keeps people safe. We urge that this plan be abandoned. Call Congress to #SaveNCAR today. buff.ly/7ka1BQA

Save NCAR from being dismantled today!

The Trump Administration has vowed to dissolve the center that provides critical extreme weather and climate data for our nation.
