Intraspecific variation in tropical trees can drive resistance to drought

Different tropical tree species can vary in their ability to withstand drought — and so too, it seems, can distinct populations of the same tree species.

Tropical forests are becoming threatened by increasingly severe stress from droughts as the climate warms. Writing in Nature, however, Smith-Martin et al.1 show that many tropical tree species adjust key drought-resistance traits along rainfall gradients — revealing an unexpected degree of hydraulic flexibility that might help forests to persist in a drier future.
