Finished my third departmental seminar in 3 weeks. Thanks to my hosts @luiza-aparecido.bsky.social in Utah, @seanmichaletz.bsky.social at UBC, and Michelle Mack at NAU, their labs, and of course my own wonderful team!

Red line graph time series of monthly carbon dioxide abundance from January 1959 through August 2025. There is a seasonal cycle and long-term increasing trend. Current levels of CO2 are at 425 ppm. This is the Keeling Curve graph. A line for CO2 10 years ago is also annotated.
Carbon dioxide (CO₂) averaged about 425 ppm in August 2025
10 years ago August averaged about 399 ppm

cover of a "pocket guide to scientific writing and publishing"
🚨Big news🚨
A Pocket Guide to Scientific Writing and Publishing is out🎉
This is the book I wish I’d had 20 years ago — short, practical, and designed to help researchers write & get their papers published
I hope it helps many
Please share with anyone who might benefit!

My paper on the mystery of the vanishing methane at Mayberry wetland is out! doi.org/10.1016/j.ag.... Many thanks to all the people who made this paper possible by gathering one of the longest continuous records of CH4 eddy covariance data in the world (14 yrs and counting!) @biometlab.bsky.social
Happy to be part of this effort led by CrisRuedas and the caminos network, which has just been published today. In it we review what has been done on pollination research in the tropical Andes and propose new lines of research. Pollination onlinelibrary.wiley.com/doi/10.1111/...

I'd love to attend the Botany 2025, but I'm staying close to ongoing work this season. Looking forward to following along and staying connected with the community!
Exploring A-Ci curves in C4 grass!
This is my first time analysing CO₂ response for a C4 plant using the LI-6800 dynamic assimilation technique.
Understanding the productivity and resilience of these tropical forages. 🌱 ✨
Plant phys folks - question- can city lights increase PAR that much to increase growing seasons? Somewhat skeptical of a PAR impact - but suspect that the warming and artificial water and fertilization signal is much much larger 🌾🌐
I have an opportunity for a new PhD student in tropical tree ecophysiology in my lab. Some more details at the link below. Please pass along!

I made tiramisu in food containers to look like the leaf-warming boxes we're using in an experiment we've almost finished setting up.
Lots of work, but worth it! (Both the experiment and the tiramisu)

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.
After 6 long years, lots of ups and downs, and being far from family, I’m defending my PhD thesis on May 6 at 12:00pm CT - just 16 days away! Still a bit to go, but wanted to share. De Puerto Tejada y Cali para el mundo.
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.

🌿🔥How heat and VPD shape tree survival? We tested how acclimation to high temperature & VPD impacts drought mortality. While heat speeds up death via leaf area expansion, VPD acclimation slows it down by enhancing stomatal control - balancing mortality timing. doi.org/10.1111/PCE....
