Plant ecophysiologist, data scientist & HMC climate & bio prof. Jessica Guo has co-authored a new paper in @newphyt.bsky.social examining how atmospheric drought shapes dryland plant productivity responses under variable precipitation regimes. Read more about Guo's work at uqr.to/guo-np.

Congratulations Ilaine!!!

Thermal acclimation of stem respiration implies a weaker carbon-climate feedback The efflux of carbon dioxide (CO2) from woody stems, a proxy for stem respiration, is a critical carbon flux from ecosystems to the atmosphere, which increases with temperature on short timescales. Ho...

Excited to share our new paper led by Tsinghua Uni ECR Zhang Han: www.science.org/doi/10.1126/.... New model based on eco-evolutionary optimality explains observed seasonal and spatial trends in stem respiration, implies stem CO2 efflux down by >25% by 2100, reducing land carbon emissions.

Very happy to be part this wonderful group! 🤍

"Thinking time —the time needed to concentrate without interruptions has always been central to scholarly work. It is essential to designing experiments, compiling data, assessing results, reviewing literature and, of course, writing. Yet, [it] is often undervalued."

New paper 📣🏔️ In tropical montane grassland, an increase of 3°C in temperature by 2100 will increase the proportion of species with entire leaves. In contrast, toothed leaves have higher stomatal conductance rates, making them vulnerable to atmospheric drought. onlinelibrary.wiley.com/doi/10.1111/...

Thank you Paulo! Glad to see this paper finally published. Thank you for sharing 😄

Thank you Martjin!

My PhD paper is out!

We showed that both forest and grassland are vulnerable to drought, but the vulnerability is attributable to different reasons: higher sensitivity to drought in forests (narrower #SM50) and lower fog exposure in grasslands. Check it out: onlinelibrary.wiley.com/doi/10.1111/...

Congrats, Luiza! You did it. Your students are lucky to have you as professor 😀

Atmospheric CO2 has passed 430 parts per million.

The last time atmospheric CO2 was at 430 ppm was during the ancient Pliocene Era, three to five million years ago, and humans didn’t exist.

The Trump administration has removed protections on thousands of acres of land in Nevada and New Mexico. The administration hopes to encourage logging, oil, and mineral mining in the region. www.nytimes.com/2025/04/08/c...

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.

Leaf Excision and Exposure Duration Alter the Estimates of the Irreversible Photosynthetic Thermal Thresholds

A busy day for the Aparecido lab! @biancazorger.bsky.social taught my Ecosystem Ecology class on warming effects on ecosystems. Later, lab undergrads, Tucker (mentored by @rebeccasenft.bsky.social) and Sydney, presented on their ug research at the College of Science res symp. Proud of this crew!! 😎🤩

Excited to share our detailed and comprehensive protocol on leaf clearing that has been developed throughout the years and across institutions. Enjoy! :)

As we close the semester and 2024, I want to acknowledge the amazing work of the undergrads in our lab.
Lucy, Sydney, Tucker, Brandt and Cindy have been outstanding! As students that had no prior research experience, they learned quickly and pulled thru in presenting… (1/3)
