Big day for me today! I presented my master's thesis project for the first time at the internal Botany symposium at UBC, and on the same day my first first-author paper was published in @biotropica.bsky.social Really grateful for everyone who has supported me along the way! doi.org/10.1111/btp....

Huge #congrats to @juan-camilo-mejia.bsky.social on his first publication, just out in @biotropica.bsky.social! Awesome thermal leaf ecophysiology work done at #STRI with @martijnslot.bsky.social. 🎉 onlinelibrary.wiley.com/doi/10.1111/...

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

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! www.findaphd.com/phds/project...

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)

A greenhouse day! 🌱🍃🙌🏼

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. www.nature.com/articles/s41...

🌿🔥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....

Buds are beginning to open. In the majority of temperate trees, all of the leaves and flowers that will grow this season were formed in the bud last year. That means that this year's growth is dependent on last year's weather. Opening buds are beautiful and worth a close look. What are you seeing?

Lightning, as in last night's dramatic storm (map) is a major natural cause of damage and death to old trees. Lightning can cause instant death (second and third photos - the same tree days apart), or damage a tree without killing it (fourth photo). Climate change is increasing lightning frequency.

Temperatures that switch on plant programmed cell death are now reality. In our new viewpoint article @newphyt.bsky.social, we propose that studying the heat induced mortality at cellular level can contribute to strategies for heat stress mitigation. nph.onlinelibrary.wiley.com/doi/full/10....

"AMF increased soil carbon by an average of 21%. However, this result was context-dependent. Controlled laboratory experiments... showed a significant net positive effect... In field experiments, the impact of AMF on soil organic carbon depended on soil type and initial organic matter content."
