The Medicine Tree: Unsettling palaeoecological perceptions of past environments and human activity [PDF]
In this paper, we consider palaeoecological approaches to past landscapes and reflect upon how these are relevant to archaeological themes concerning concepts of environmental change and the role of past and present human communities in these processes ...

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

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.

Specificity in legume-rhizobia symbioses [PDF]
Most species in the Leguminosae (legume family) can fix atmospheric nitrogen (N₂) via symbiotic bacteria (rhizobia) in root nodules. Here, the literature on legume-rhizobia symbioses in field soils was reviewed and genotypically characterised rhizobia ...

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