Global variability in hydraulic traits and water use strategies of mountain shrubs and dwarf shrubs

open access: yesPlant Biology, Volume 27, Issue 7, Page 1253-1270, December 2025.
Shrubs show a wide range of hydraulic strategies to achieve a balanced and favourable water status in mountain areas. Abstract Shrubs are perennial, multi‐stemmed woody plants whose adaptation to stress factors allows them to colonise extreme habitats, including high elevations. Accordingly, shrubs are one of the most important growth forms in mountain

Linking Relationship of Ecosystem Service Supply and Demand Into Sustainable Development Goals (SDGs)

open access: yesLand Degradation &Development, Volume 36, Issue 17, Page 6003-6024, November 2025.
ABSTRACT Ecosystem services (ES) play a crucial role in sustainable development. We systematically assessed the spatial and temporal dynamics of ecosystem service supply (ES‐s) and demand (ES‐d) in China from 1990 to 2020 by using a supply–demand matrix integrated with land use/cover data. The findings indicate that in 2020, grasslands accounted for 28.

Groundwater Altered Water Balance and Plant Water Use Efficiency in Desert Ecosystems

open access: yesWater Resources Research, Volume 61, Issue 11, November 2025.
Abstract Groundwater is an important water source in water‐limited desert ecosystem. Less attention has been paid to how the water balance and plant performance in such ecosystems vary with the presence or absence of groundwater. Appropriate replanting strategies play a pivotal role in preventing desertification.
