Some tropical trees cool their leaves to survive the heat — but not all species have ways to cope

"How do you cool yourself on a hot day? Perhaps you find shade, switch on a fan
or retreat to air conditioning? But spare a thought for tropical forest trees.
As the climate warms, they must either adjust to the heat, adapt over
generations, or begin a slow decline toward death.

In full sun, tropical leaves can become much hotter than the surrounding air –
hot enough to slow – or even stop – the life-sustaining process of
photosynthesis.

So how can trees keep their leaves within safe temperature limits? And are some
species better at this than others? Our new research examined that question.

We found some tropical tree species have ways to cope with damaging
temperatures in warmer parts of their range. This could give them an advantage
over competitors as the climate continues to warm."
