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.
