Mechanisms of xylem hydraulic recovery after drought in Eucalyptus saligna

Alice Gauthey et al.

Summary: This study evaluated the recovery of xylem hydraulic capacity in Eucalyptus saligna plants after drought stress and rewatering. The findings revealed that severe drought stress resulted in high levels of xylem embolism and no evidence of embolism refilling was observed in the weeks following rewatering. However, the plants were able to recover their hydraulic capacity through the growth of new xylem tissue over a period of 6 months.

Lack of hydraulic recovery as a cause of post-drought foliage reduction and canopy decline in European beech

Matthias Arend et al.

Summary: This study investigated the impact of the 2018 European drought on beech trees and found that the hydraulic conductance of the trees was lost during the drought and did not recover in the following year. The decline in hydraulic function was associated with defoliation symptoms and a decrease in wood starch concentration. The findings suggest that leaf development after drought acclimates to mitigate disturbances in canopy hydraulic function.

Drought stress recovery of hydraulic and photochemical processes in Neotropical tree saplings

Olivier Jean Leonce Manzi et al.

Summary: Climate models predict an increase in severity and frequency of droughts, which could impact tropical forests. This study found that hydraulic trait values decreased faster than photochemical trait values during drought stress. After re-watering, F-v/F-m recovered rapidly, followed by ETRmax, Psi(md), and g(s), showing that species with large stomatal and leaf safety margin and low pi(tlp) are less impacted by drought but have lower recovery in photochemical efficiency.

Combined high leaf hydraulic safety and efficiency provides drought tolerance inCaraganaspecies adapted to low mean annual precipitation

Guang-Qian Yao et al.

Summary: The study revealed that Caragana species adapted to low precipitation environments exhibit specific traits in leaf hydraulic conductance, gas exchange, and vein anatomy, with tighter stomatal control mediated by higher ABA accumulation leading to increased water use efficiency and hydraulic safety during drought stress.

An increase in xylem embolism resistance of grapevine leaves during the growing season is coordinated with stomatal regulation, turgor loss point and intervessel pit membranes

Yonatan Sorek et al.

Summary: The study found that grapevines are able to modify their hydraulic traits over the growing season to achieve lower xylem water potential without compromising gas exchange, leaf turgor, or xylem integrity. Seasonal changes should be taken into account when modeling ecosystem vulnerability to drought or comparing datasets obtained at different phenological stages.

Positive pressure in xylem and its role in hydraulic function

H. Jochen Schenk et al.

Summary: The actual location and mechanisms behind positive xylem pressure remain largely unknown, but it can be driven by physical forces, osmotic exudation, or hydraulic pressure. Future research should focus on similarities and differences in mechanistic models, evaluate hydraulic functions, and propose research methods that avoid cutting artefacts.

From the comfort zone to crown dieback: Sequence of physiological stress thresholds in mature European beech trees across progressive drought

Lorenz Walthert et al.

Summary: This study aimed to develop an empirical stress-level scheme to describe the physiological response of mature European beech trees to drought. The researchers identified five stress levels based on the observed responses to decreasing water potential. They found that exposure to stress levels III-V for only one month was enough to trigger substantial crown dieback in beech trees on shallow soils, while deep soil with high water holding capacity prevented drought stress in beech trees.

Linking plant hydraulics and the fast-slow continuum to understand resilience to drought in tropical ecosystems

Rafael S. Oliveira et al.

Summary: Tropical ecosystems have the highest levels of biodiversity, water cycling, and carbon absorption on Earth. Plant hydraulics is crucial for understanding and predicting the dynamics of tropical vegetation, with a trade-off between drought avoidance and hydraulic safety being a major axis of physiological variation. Additionally, there is a proposed axis of hydraulic trait variation linking vulnerability to hydraulic failure and growth, impacting community assembly and potentially making simulated rainforest communities more vulnerable to drought.

Evolutionary relationships between drought-related traits and climate shape large hydraulic safety margins in western North American oaks

Robert P. Skelton et al.

Summary: The study found that 50% of embolism occurs at water potentials below -2.7 MPa in western North American oaks, with the most resistant species able to withstand -6.6 MPa. Differences in xylem vulnerability to embolism were found between clades, while closely related species within each clade showed little variation in their capacity to withstand air entry. This phylogenetic conservatism in xylem physical tolerance, along with the correlation between species distributions along rainfall gradients and their dehydration tolerance, suggests that closely related species occupy similar climatic niches and may have shifted their geographic ranges along aridity gradients.

Representation of Plant Hydraulics in the Noah-MP Land Surface Model: Model Development and Multiscale Evaluation

Lingcheng Li et al.

Summary: In this paper, a novel plant hydraulics scheme (PHS) for land surface model Noah-MP (Noah-MP-PHS) is introduced, which shows improved representation of plant water stress and enhanced water and carbon simulations, especially under dry soil conditions. The PHS considers the whole-plant hydraulic strategy, including root-level soil water acquisition, stem-level hydraulic conductance and capacitance, and leaf-level anisohydricity and hydraulic capacitance.

Biogeographic history and habitat specialization shape floristic and phylogenetic composition across Amazonian forests

Christopher Baraloto et al.

Summary: This study investigated the turnover among and within lineages of Amazonian trees in different geographic and environmental gradients due to biogeographical history and habitat specialization. The research found significant species turnover between Peru and French Guiana, with only a small percentage of species shared. White-sand forests were identified as habitats harboring most of the habitat specialists in both regions.

Summary: Research has found that the rupture of leaf vascular networks can lead to tissue damage in plants caused by water stress. This process is actually the main reason for the wilting and death of plants.

Summary: Leaf habit has been proposed to define the drought avoidance and plant economics in tropical trees, but it alone cannot explain the patterns of trait variation. Different strategies for adaptation exist within leaf habits.
