The mystery of leaf size solved
And a feature story by lead author Ian Wright for The Conversation here.
For the first day of Spring, we’ve got a global team of researchers who have cracked the mystery of leaf size. Their research was published today as a cover story in Science.
Associate Professor Ian Wright from Macquarie University, with 16 colleagues from Australia, the UK, Canada, Argentina, the USA, Estonia, Spain, and China analysed leaves from over 7,600 species.
They teamed that data with a new theory that in much of the world the key limiting factor for leaf size is night temperature and the risk of frost damage to leaves. Until now, the textbooks said it’s a balance between water availability and overheating.
