Recent decades have been characterized by increasing temperatures worldwide, resulting
in an exponential climb in vapor pressure deficit (VPD). VPD has been identified as an …

Nearly all plant families, represented across most major biomes, absorb water directly
through their leaves. This phenomenon is commonly referred to as foliar water uptake …

Stomata are orifices that connect the drier atmosphere with the interconnected network of
more humid air spaces that surround the cells within a leaf. Accurate values of the humidities …

Dry deposition of ozone is an important sink of ozone in near‐surface air. When dry
deposition occurs through plant stomata, ozone can injure the plant, altering water and …

Global urbanization drastically reshapes the land–atmosphere interactions, biogeochemical
cycles, and ecosystems in the integrated earth system. Urban trees are used extensively for …

A surge of papers have reported low leaf vulnerability to xylem embolism during drought.
Here, we focus on the less studied, and more sensitive, outside‐xylem leaf hydraulic …

We compiled hydrogen and oxygen stable isotope compositions (δ2H and δ18O) of leaf
water from multiple biomes to examine variations with environmental drivers. Leaf water δ2H …

Understanding the short‐term responses of mesophyll conductance (gm) and stomatal
conductance (gsc) to environmental changes remains a challenging yet central aspect of …

Many plant water use models predict leaves maximize carbon assimilation while minimizing
water loss via transpiration. Alternate scenarios may occur at high temperature, including …

The vast majority of measurements in the field of plant hydraulics have been on small‐
diameter branches from woody species. These measurements have provided considerable …
