Severe droughts have caused widespread tree mortality across many forest biomes with
profound effects on the function of ecosystems and carbon balance. Climate change is …

Seasonally dry tropical forests (SDTF) are located in regions with alternating wet and dry
seasons, with dry seasons that last several months or more. By the end of the 21st century …

The leaf economics spectrum (LES) provides a useful framework for examining species
strategies as shaped by their evolutionary history. However, that spectrum, as originally …

Leaf water potential (ψleaf), typically measured using the pressure chamber, is the most
important metric of plant water status, providing high theoretical value and information …

Determining physiological mechanisms and thresholds for climate‐driven tree die‐off could
help improve global predictions of future terrestrial carbon sinks. We directly tested for the …

Shifts in rainfall patterns and increasing temperatures associated with climate change are
likely to cause widespread forest decline in regions where droughts are predicted to …

Climate change exposes vegetation to unusual drought, causing declines in productivity and
increased mortality. Drought responses are hard to anticipate because canopy transpiration …

Xylem hydraulic failure has been recognized as a pervasive factor in the triggering of
drought-induced tree mortality. However, foundational evidence of the mechanistic link …

Hydraulic failure is one of the main causes of tree mortality in conditions of severe drought.
Resistance to cavitation is known to be strongly related to drought tolerance and species …

Plant survival during drought requires adequate hydration in living tissues and carbohydrate
reserves for maintenance and recovery. We hypothesized that tree growth and hydraulic …
