We found that when temps hit 30°C+, C3 plants start struggling - their carbon metabolism gets disrupted, they burn through sugar stores faster, and even their isotope signatures change. Meanwhile C4 plants? They're basically chilling like "this is fine" 😎 www.nature.com/articles/s44...

Where we collect seed for restoration matters. In a new paper led by Jayden Engert, we examined where nurseries source seed for rainforest plantings and discuss what that means for restoration success. www.sciencedirect.com/science/arti...

In full sun, tropical leaves can become much hotter than the surrounding air. Their ability to cope can be a matter of life or death. 👉 Read the full story: theconversation.com/some-tr...

New research reveals some rainforest tree species use self-cooling strategies to withstand rising temperatures, but others are more at risk. Full story: shorturl.at/piQ5B

Featured on the cover of @globalchangebio.bsky.social is a thermal image of Elaeocarpus Grandis taken at @jcuofficial.bsky.social Daintree Rainforest Observatory. In this species we find that populations originating from warmer climates have narrower leaves with higher rates of water loss.

Check out our piece in @theconversation.com explaining how intraspecific trait coordination across climatic gradients helps to avoid heat stress in some (but not all) tropical tree species theconversation.com/some-tropica...

Can tropical rainforest trees keep their cool? Now out in @globalchangebio.bsky.social we explored whether intraspecific variation in leaf energy balance was a result of adaptation to local climate. doi.org/10.1111/gcb....

What a wonderful time sharing ideas with fellow plant nerds 💚

Heading to Oaxaca for #ATBC2025 ? Make sure you stop by our symposium for all things leaf temperature, heat tolerance, and tradeoffs across climate gradients 🌿💧🌡️

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...

Proud to have my thermal image on the cover of this fantastic issue - now time to check out the research inside!

🔥Can heatwaves leave a thermal leaky legacy?🔥 Check out our latest paper on gmin dynamics during and after thermal stress🍃📄 Extremely proud of my student Viviane! Special thanks to @hcochard.bsky.social @torresruizjm.bsky.social @martijnslot.bsky.social doi.org/10.1093/plph...

Happy to share a new paper, "Effects of Hot Versus Dry Vapor Pressure Deficit on Ecosystem Carbon and Water Fluxes," led by the amazing Miriam Johnston w/ @mallorybarnes.bsky.social and others agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Check out our new article just out in The Conversation highlighting the effects of warming leaves +4°C in tropical trees. 🌿🌡️ theconversation.com/study-shows-...

How do tropical rainforest trees respond to warming? 🌡️🌿We experimentally warmed canopy leaves by 4°C for 8 months and found significant declines in photosynthesis and stomatal conductance, with no shift in Topt. Read the new paper, led by Kristine Crous here: shorturl.at/AVTOk

Time to introduce myself! Recently, I defended my thesis titled "Patterns and Drivers of Leaf Thermoregulation in Rainforest Trees of the Australian Wet Tropics" where I focused on the role of within-species acclimation and adaptation on leaf temperature. Here’s a little summary of what went on…

Why am I a plant ecophysiologist? 7 years ago, I sat above the trees in a mature tropical rainforest and enter an entirely new world. Thanks to the Daintree Rainforest Observatory's canopy access crane. Now our much loved research station is under financial threat www.abc.net.au/news/2024-11...
