Our new study from RWANDA TREE shows that:
Species with big leaves & low stomatal conductance tolerate more heat, but with tighter safety margins.
Heat tolerance acclimates,but partially:+0.31°C per +1°C Tgrowth
Leaf temperature matters more than heat tolerance for survival. doi.org/10.1111/pce....
Photosynthetic Heat Tolerance Partially Acclimates to Growth Temperature in Tropical Montane Tree Species
Climate warming poses a risk to tropical montane trees by narrowing their thermal safety margins, particularly in species with traits that lead to higher leaf temperatures. While photosynthetic heat ...

Excited about our new paper asking: Why does the growth of most life have an optimal temperature below 40°C? We argue the average maximum oceanic temperatures of <37°C for 2+ billion years drove evolution of the temperature optima of prokaryotes. 1/5

Earth's Climate History Explains Life's Temperature Optima
We propose that the origin of the temperature optima of life results from two discrete evolutionary selection pressures that constrained the evolution of fundamental biochemistry and growth of most l...

New in @sciencemagazine, a review on Scaling plant responses to heat (www.science.org/doi/10.1126/...). Increased temperature along with acute heat waves threaten the ability of terrestrial vegetation to act as a carbon sink, but predicting how plants will respond to heat is challenging.
Scaling plant responses to heat: From molecules to the biosphere
Predicting plant responses to rising temperatures, including acute heat waves and hot droughts of varying intensity and duration, is central to addressing the climate and biodiversity crises. However,...

On Friday (17/01/2025) at 10:00 AM Swedish time,I will defend my doctoral thesis, "Heat and drought responses of tropical trees in a warming world
( gupea.ub.gu.se/handle/2077/84…" The opponent is Prof Emanuel Gloor https://gu-se.zoom.us/j/65080289605?pwd=hjt3BmHE6Hi8Jl3vlz8gwUZkUrM5St.1
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

Thanks Kali Middleby

So happy that my thesis is now printed! Looking forward to what the future holds for me 🙌
The chapter I contributed is about temperature effects on the trees of BCI. The electronic book should be downloadable, but let me know if you want a copy of my chapter.

Our review of the direct response of stomata to temperature just came out in an issue (OK, it was 3 months ago but I just noticed).

We cover what (little) is known, & possible mechanisms and implications.

Several more papers in the works. Watch this space!

The poorly‐explored stomatal response to temperature at constant evaporative demand
The direct response of stomata to temperature (the response when evaporative demand is held constant by adjusting ambient humidity) is very poorly known. This review summarises the current state of k...

Amber, fossil conifer resin, is now known from every continent including Antarctica. Trees and forests have been migrating throughout the Earth for all of their existence. But now, rapid climate change exceeds the ability of trees to migrate and survive. The only solution is to end fossil fuel use.
