Hi All!
I'm back from sabbatical and teaching Plant Ecophys again - a class near and dear to my heart! In the past, I've welcomed grad students and post-docs to share their research with students and their stories about how they got into the field.....

I am seeking a postdoc to conduct studies on phenotyping crop physiology and growth using high-throughput techniques combined with AI/ML. An ideal candidate is a motivated individual with relevant skills or a strong desire to learn. If interested, feel free to DM me for more details.

"Heat waves are getting more dangerous with climate change — and we may still be underestimating them" | Nice piece by @afreedma.bsky.social for @cnn.com that references our recent @pnas.org article: edition.cnn.com/2025/06/23/c...

Heat waves are getting more dangerous with climate change — and we may still be underestimating them | CNN

The intensifying and expansive heat wave affecting around 150 million people in the United States from Wisconsin to Washington, DC, bears the hallmarks of human-caused global warming.

Check out this recently published paper by Seeley et al. in the Journal of Ecology illustrating how remote sensing reveals inter- and intraspecific variation in riparian cottonwood (Populus spp) responses to drought.

Leaf drought and heat tolerance are integrated across three temperate biome types

I am very happy to see our paper out! Plant responses to many stresses are mediated by the same processes and I have long wondered how this relates to hotter droughts.

Need a Monday pick-me-up?

Here's a throwback to 2022, when our field ecology program director Susan Bush had an extraordinary encounter with a huge band of coatimundis while working at our field site in Wet Beaver Creek, AZ

How many can you spot??

Mapping the roots of saguaros at Saguaro NP. The DBG is partnering with SNP and the U of Wyoming to map the roots of saguaros. Knowing the distribution of saguaro roots reveals how sensitive they are to droughts, and to what extent these iconic plants engineer the water cycle of desert ecosystems.

David Lynch gave us the language we needed to better articulate the indescribable strangeness of our shared reality. “Lynchian” is so overused because it’s a viscerally understandable word without any known synonyms. I can’t imagine a more beautiful artistic legacy than that.

Excited to share our paper with Anna Gardner and @florianabusch.bsky.social in Plant Ecophysiology!🌿

We review challenges in interpreting plant stress responses using gas exchange data, offer solutions to improve accuracy and discuss gaps in our current knowledge.

www.sciltp.com/journals/Pla...

$Detailed representation of H2O gas exchange (left) and CO2 gas exchange (right) at the adaxial (upper) and abaxial (lower) leaf surfaces in an amphistomatous leaf. This panel illustrates the separate gas exchange processes for each leaf surface, which can be measured individually if the upper and lower cuvettes are analysed separately—though this setup is not common in commercial gas exchange systems. Stomatal, cuticle, and boundary layer resistances are depicted for both surfaces, along with the mole fractions of water vapour and CO2.$

DPEL in the news! Check out Brad Posch discussing how cottonwood trees stay cool in the summer heat: www.12news.com/video/news/r...

Trees able to cool themselves down even in extreme Arizona heat, research shows

Freemont cottonwoods found across Arizona can essentially sweat to cool themselves off.
