Traits and functions of alpine plant communities respond strongly but not always sufficiently to in situ climate change

open access: yesNew Phytologist, EarlyView.
Summary Increasing climate warming and summer droughts are known to affect mountain plant communities, their functional traits and life strategies. However, little is known about how strongly and efficiently communities respond to climate change, and how tightly plant responses are linked to responses of ecosystem functions.

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

open access: yesPlant Biology, EarlyView.
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

Long‐term assessment of the Moss Layer Transfer Technique for the restoration of Sphagnum‐dominated peatlands

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Peatlands are crucial for carbon storage and biodiversity but face increasing human degradation. The Moss Layer Transfer Technique (MLTT) has emerged as an effective method for restoring Sphagnum‐dominated vegetation in post‐extracted horticultural peatlands. Objectives This study evaluates vegetation restoration trajectories over

Ecological Modules Link Soil Aggregate Stability, Chemical Properties and Fungal Communities Under Plant Species‐Based Revegetation

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 6, December 2025.
Under plant species‐based revegetation, network analysis revealed that fungal communities exhibited modular responses to variations in soil aggregates and chemical properties. Soil chemical properties shaped symbiotic fungi‐dominated modules; soil aggregates and chemical properties shaped pathogenic fungi‐dominated modules; while saprophytic fungi ...
