Aspen trees remember past droughts, study finds
Original: Aspens 'remember' past drought in their leaves, 3-year experiment finds
A three-year experiment has found that aspen trees carry a physiological memory of past droughts, which shows up in the way their leaves respond to dry conditions. Researchers say trees that experienced earlier drought adjusted their leaf function differently from those that had not, suggesting plants can retain lasting responses to environmental stress beyond the event itself.
Why now: New research on plant memory offers fresh insight into how forests may cope with climate change-driven droughts.
