Hydrothermal alteration on dolomitic marble in a hypogenic karst in Macedonia

open access: yes
The Mariovo basin in North Macedonia is an important karst area in the Balkans, home to dolomite and calcite marble formations. The Melnica Pestera hypogene karst proves a hydrothermal driven speleogenesis, which shows relation to alteration shown on ...

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

open access: yesNew 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 ...

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

open access: yesNew 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

open access: yesPlant 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 ...

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

open access: yesPlant 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.

The Earth's Greatest Porous Media

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract How deeply does modern meteoric water circulate into the continental crust? How deep is the Earth's Critical Zone (CZ), the top layer of the continental lithosphere that co‐evolves with the atmosphere, hydrosphere, and biosphere, extending from vegetation canopy down to fresh bedrock and the base of active groundwater circulation?
