TL;DR

It is found that stomatal closure, hydraulic impairment and leaf browning occurred concurrently, in contrast to the progressive sequence typically observed in trees, which highlights the need for grass-specific parameterization of drought responses in process-based models.

Divergence in wilt tolerance across the range of Mimulus guttatus in the absence of stomatal regulation

Whether phenotypes and environments predict performance under stress is central to ecology and evolution and can reveal species’ vulnerability to global change. We sampled Mimulus guttatus range-wide to test whether reproductive, morphological, and physiological traits predict drought responses. Surprisingly, we find t...

Stomatal sensitivity to VPD across 38 tree species reflects past drought responses but is little explained by stomatal and leaf economic traits

This interspecific comparison reveals substantial variation in stomatal responses to atmospheric demand that is relevant to drought responses, but cannot be readily inferred from commonly measured leaf traits.

Declining hydraulic safety in a drier world.

Forests worldwide are increasingly exposed to soil drought under climate change, with their fates depending on the ability to maintain essential functions like water transport (hydraulics) and photosynthesis. Acclimation is expected to mitigate drought impacts, but the extent to which trees acclimate remains largely un...

Stable isotope insights into contrasting drought-response strategies of five native broadleaf tree species in East Central Europe

Future forest dynamics under climate change will largely depend on the physiological acclimation capacity of the tree species to the increasing environmental stress. We combined carbon and oxygen stable isotope analyses with growth measurements to estimate the effects of atmospheric CO 2 and drought stress on intri...

Hydraulic Trait Strategies Lead to Divergent Tree Growth Responses to Multidecadal Climate Variability

Climate change, including altered precipitation patterns, is impacting the growth, competition, survival, and carbon allocation dynamics of trees globally. Using 22 years of data, we aimed to link the strength and timing of species‐specific stem growth responses to water stress and species‐level hydraulic strategy tr...

Leaf Hydraulic Conductance Mediates the Effect of Precipitation on Leaf Nutrients in Subtropical Forests.

Precipitation will increase in some regions and decrease in others. These changes can alter plant nutrient status, and consequently, impact the terrestrial carbon cycle. However, the ecological and physiological mechanisms underlying plant nutrient responses to changes in precipitation remain poorly understood. Here, w...
