Study finds giant tropical trees compensate for height-related water transport challenges

Summary

New research led by the University of Exeter and Cardiff University, published in the journal Science, challenges conventional scientific theory about water transport in tall trees. The study found that giant Dipterocarp trees have internal adjustments to water transport that "fully compensate" for the challenges of drawing water to their topmost branches, contradicting the long-held belief that tree height limits water transport and increases drought vulnerability.

Conventional scientific theory suggests that as trees grow, it becomes harder to transport water from roots to leaves – limiting growth and making trees more vulnerable to drought.
