Plants are heating up faster than the air around them – and climate models are missing it

A new study shows that rising temperatures are going to hit plants harder than most current models predict, which could have significant implications for everything from plant and animal biodiversity ...

Another paper examining the differences between canopy and air temperature- this time with ESMs and observation-based datasets to constrain future estimates. This has been a long time coming- and I'm proud to have finally brought it to its published form. www.nature.com/articles/s41...

Despite leaf and air temperature often being highly correlated, their differences can reveal subtle details about plant status and the surface energy balance. Awesome review paper on this topic led by Xu Lian and Jianing Fang that was great to contribute to: www.nature.com/articles/s41...

Leaf temperature and its departure from ambient air temperature - Nature Plants

How leaf temperature deviates from air temperature informs species’ thermoregulation strategies. This meta-analysis-based Review presents a global picture of thermoregulation behaviours and the implic...

⚒️ Article: Widespread underestimation of rain-induced soil carbon emissions from global drylands @ngocnb.bsky.social @trevorkeenan.bsky.social www.nature.com/articles/s41...

Rain-induced carbon losses in drylands contribute largely to the interannual variability of the land carbon sink, but do current partitioning methods and models capture them? Check out our new paper led by @ngocnb.bsky.social & @trevorkeenan.bsky.social to learn more: www.nature.com/articles/s41...

Widespread underestimation of rain-induced soil carbon emissions from global drylands - Nature Geoscience

Eddy-covariance observations suggest that rain pulses over global drylands drive substantial soil carbon emissions, which are underestimated in current measurement and modelling approaches.

Interested in how #drought influences vegetation water use? Led by Feng Li & Zheng Fu, we address: 1) How does water use efficiency (WUE) and its components change during drought? (2) What regulates WUE? (3) How do these components reciprocally influence WUE? onlinelibrary.wiley.com/doi/10.1111/...

Limited Regulation of Canopy Water Use Efficiency by Stomatal Behavior Under Drought Propagation

We examined the trajectories, interdependencies and drivers of multidimensional WUE metrics and their components (gross primary production (GPP), evapotranspiration, transpiration (T), and canopy con....

The peer review process is TIME CONSUMING, and declining review invitations because of being TOO BUSY is ENTIRELY ACCEPTABLE (and NORMAL). That said, it is so UNBELIEVABLY HELPFUL when someone makes ALTERNATIVE SUGGESTIONS FOR REVIEWERS.

Lovely start to 2025 -- cycling and pastries on a beautiful day in Tucson with David Moore!

Thank you DC for another amazing AGU! #AGU24 did not disappoint, and it was great to see lab members presenting and discussing their research (@savcardenas.bsky.social & Zexi Shen). Now, the introvert in me will need a day (or week) to decompress and do some deep breathing exercises 😅!!!

Hard to believe that #AGU24 is next week! A list of our group presentations and sessions are here: agu.confex.com/agu/agu24/me... Looking forward to catching up!
