Cooling by melting precipitation in Alpine valleys: An idealized numerical modelling study [PDF]

open access: yes, 2006
Cooling by melting precipitation in Alpine valleys is investigated. In this case, the latent heat required for melting the falling snow is continuously removed from the valley air until the snowline reaches the valley bottom. Numerical simulations with a

Spatiotemporal dynamics and driving mechanisms of alpine peatland wetlands in the eastern Qinghai–Tibet Plateau based on a Vision Transformer model

open access: yesEcological Indicators
The Zoige Wetland, located in the eastern Qinghai–Tibet Plateau, is the world’s largest alpine peatland. Understanding its spatiotemporal dynamics and driving mechanisms is essential for sustaining fragile plateau ecosystems.

Benthic Biodiversity in Subarctic Stream Networks: Headwaters as Upholders of Variation Through Space and Time

open access: yesFreshwater Biology, Volume 71, Issue 6, June 2026.
ABSTRACT Headwaters often contribute disproportionately to network‐scale benthic biodiversity as differences in community composition between separate headwater streams (β‐diversity) can be high although local (α) diversity may be low. Most research on stream β‐diversity has adopted a spatial perspective, whereas temporal β‐diversity remains largely ...

Determinants of Soil Microarthropod Community Biodiversity in the Svalbard High Arctic: Locality or Vegetation Community?

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Arctic ecosystems like Svalbard are rapidly changing, yet soil microarthropods remain difficult to monitor due to limited baseline data and demanding field and identification work. Using 172 soil samples from 33 localities, we tested whether vegetation maps could serve as proxies for soil microarthropod communities.

La recherche alpine aujourd’hui [PDF]

open access: yes, 2008
Alpine research benefits from several international coordination networks, only one of which – ISCAR (the International Scientific Committee on Research in the Alps) – works solely in the Alpine arc.

Determining Spatially Variable Peat Depths of an Alpine Peatland in the Qinghai‐Tibet Plateau

open access: yesJournal of Geophysical Research: Biogeosciences
Abstract Understanding peat depths is crucial for assessing carbon dynamics within peatlands. However, accurately estimating peat depths across large areas remains challenging. In this study, we developed a novel approach integrating a machine‐learning based regression modeling with an optimized field sampling ...

Habitat‐Driven Sexual Dimorphism in Triplophysa strauchii Between Oxbow Lake and Stream: A Geometric Morphometric Analysis

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
The combined effects of sexual selection and natural selection give rise to sexual dimorphism in operculum and eye morphology of T. strauchii across the two river basins. And our study reveal the fine‐scale responses of fish sexual dimorphism to diverse selective forces.

Impact of climatic change on alpine ecosystems: inference and prediction [PDF]

open access: yes, 2010
Alpine ecosystems will be greatly impacted by climatic change, but other factors, such as land use and invasive species, are likely to play an important role too. Climate can influence ecosystems at several levels.
