Severe droughts have been associated with regional‐scale forest mortality worldwide.
Climate change is expected to exacerbate regional mortality events; however, prediction …

The extreme drought event that occurred in Western Europe during 2003 highlighted the
need to understand the key processes that may allow trees and stands to overcome such …

The evolution of lignified xylem allowed for the efficient transport of water under tension, but
also exposed the vascular network to the risk of gas emboli and the spread of gas between …

The ability of plants to supply water to their leaves is intimately associated with survival.
Water supply to leaves depends on maintaining an intact water column in the xylem from the …

Forest dieback caused by drought‐induced tree mortality has been observed world‐wide.
Forecasting which trees in which locations are vulnerable to drought‐induced mortality is …

Bordered pits are cavities in the lignified cell walls of xylem conduits (vessels and tracheids)
that are essential components in the water‐transport system of higher plants. The pit …

We studied 15 riparian and upland Sonoran desert species to evaluate how the limitation of
xylem pressure (Ψx) by cavitation corresponded with plant distribution along a moisture …

Climate change resulting from increased concentrations of atmospheric carbon dioxide
([CO2]) is expected to result in warmer temperatures and changed precipitation regimes …

Angiosperm and coniferous tree species utilize a continuum of hydraulic strategies.
Hydraulic safety margins (defined as differences between naturally occurring xylem …

The effect of extreme climate events on ecosystems is an important driver of biotic responses
to climate change. For forests, extreme drought has been linked to negative effects such as …
