A great way to end the year! Our new paper, led by Daniel B. Metcalfe and published in @NatureComms, shows how biases in tropical research risk undermining environmental policy where it matters most. www.nature.com/articles/s41...

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....

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.

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
Surrounded by lush vegetation in a tropical forest canopy, three take-away containers have been customised to warm leaves continuouslyA density plot shows the distribution of observed leaf temperatures for one example species - Myristica globosa. The graph shows that warmed leaves surpass their optimum temperature far more frequently than control leaves, and are close to their critical temperature threshold

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.
