Forest under stress: responses and recovery of water relations across scales during the compound drought in summer 2022

New Phytologist, EarlyView.
A schematic showing the links of tree‐scale (root‐, stem‐, and leaf‐level) and ecosystem‐scale water relations during the CSAD at CH‐Lae. Summary The summer of 2022 was characterized by compound soil and atmospheric drought (CSAD; low soil water content, SWC, and high vapor pressure deficit, VPD) in Central Europe, threatening forest carbon ...

A Review of Value Realization and Rural Revitalization of Eco-Products: Insights for Agroforestry Ecosystem in Karst Desertification Control

Land
Amid global rural decline, the main approach to rural revitalization (RR) is to transform rural ecological resources into development advantages by means of ecological product value realization (EPVR).

Coupled decline in growth and fine‐branching signals the onset of drought‐induced European beech mortality

New Phytologist, EarlyView.
Conceptual synthesis of drought‐induced mortality in European beech. Summary Severe and recurrent droughts have caused widespread canopy decline and mortality in European forests. Drought‐induced mortality occurs when structural damage and physiological dysfunction impair a tree's ability to recover, yet it remains unclear when trees transition from ...

The impact of seasonal variations in inner bark width and xylem growth on irreversible annual stem diameter measurements

Plant Biology, EarlyView.
The seasonal variation in inner bark width differed from that of xylem growth, indicating that xylem phenology cannot be reliably assessed without cellular observations. Abstract To better interpret continuous xylem growth measurements from dendrometers, we evaluated how the widths of developing xylem and phloem, along with seasonal trends in inner ...

Suitability of agronomic water saving in karst areas and its enlightenment in the karst desertification control

Heliyon
The special "dual" hydrogeological structure in karst areas causes rainfall easily "leaking" into the ground, resulting a unique "karst drought". In these areas, drought and insufficient water resources seriously restrict the sustainable development of agriculture. In order to restore the ecology of karst desertification, develop ecological industries,

Stress‐specific metabolic and physiological responses to drought and waterlogging in Allium cepa L. and Allium × cornutum Clementi ex Vis.

Plant Biology, EarlyView.
Drought and waterlogging induce distinct species‐specific metabolic, physiological and transcriptional responses in Allium cepa and Allium × cornutum. Abstract Increasing variability in water availability, caused by changing climatic conditions, is a major constraint for onion production.

Long-Term Discharge Records from United States and European Karst Springs: Data Limitations in Trend Analysis. [PDF]

Ground Water
Karst spring discharge trend (the change in discharge over a period greater than 30 years for each spring) does not depend on discharge variability. Insets show two springs with contrasting discharge variability (variable vs. extremely high variability) but similar discharge trends.
