We investigated the occurrence of freezing-induced cavitation in the evergreen desert shrub Larrea tridentata and compared it to co-occurring, winter-deciduous Prosopis velutina. Field measurements ...

The early 2000s were a time of exceptional drought in the American Southwest. The year 2002 in particular was perhaps the driest in the last 500 years, according to tree-ring historical ...

For trees, the price of the light-harvesting advantage of height is metastability. Active water loss from the leaf stomata enables sap to be drawn up the tubes of the xylem to a far greater height ...

In a nearby park, just down the block, or maybe in your own backyard, you'll find an engineering marvel that has stumped scientists for centuries: a tree. It may look ordinary, but its plumbing is ...

As is well known now, California is in its fourth year of drought. As a result, mass mortality of trees and shrubs is happening more quickly than researchers can quantify. Rapid changes in vegetation ...
