Changes in species composition in alpine snowbeds with climate change inferred from small-scale spatial patterns [PDF]

open access: yes, 2008
Alpine snowbeds are characterised by a very short growing season. However, the length of the snow-free period is increasingly prolonged due to climate change, so that snowbeds become susceptible to invasions from neighbouring alpine meadow communities ...

Characterization of the spatial distribution of plateau pika burrows along an alpine grassland degradation gradient on the Qinghai–Tibet Plateau

open access: yesEcology and Evolution, 2021
Plateau pika burrows are common feature of degraded grassland in the Qinghai–Tibet Plateau (QTP) and serve as an important indicator of pika activity and grassland degradation.

Spatial-Temporal NDVI Variation of Different Alpine Grassland Classes and Groups in Northern Tibet from 2000 to 2013

open access: yesMountain Research and Development, 2015
The Normalized Difference Vegetation Index (NDVI) can usually be used as a good proxy for evaluating potential variability in regional ecosystems and under climate change.

Alpine grassland fPAR change over the Northern Tibetan Plateau from 2002 to 2011

open access: yesAdvances in Climate Change Research, 2017
In this study, two different methods including Digital Camera and Reference Panel (DCRP) and traditional in situ fPAR observation for measuring the in situ point fPAR of very short alpine grass vegetation were compared, and the Moderate Resolution ...

On the trails of Josias Braun-Blanquet : changes in the grasslands of the inneralpine dry valleys during the last 70 years. First results from the 11th EDGG Field Workshop in Austria [PDF]

open access: yes, 2020
The 11th EDGG Field Workshop was held from 6 to 13 July 2018 in Austria. Its aim was to revisit dry grasslands in the inneralpine dry valleys of Austria that were investigated in the late 1950s by Braun-Blanquet and to collect high-quality biodiversity ...

Responses of Soil Microbial Metabolic Activity and Community Structure to Different Degraded and Restored Grassland Gradients of the Tibetan Plateau

open access: yesFrontiers in Plant Science, 2022
Climate change and land-use disturbances are supposed to have severely affected the degraded alpine grasslands on the Tibetan Plateau. Artificial grassland establishment has been implemented as a restoration tool against grassland degradation.

Migration of vegetation boundary between alpine steppe and meadow on a century-scale across the Tibetan Plateau

open access: yesEcological Indicators, 2022
The distribution of alpine vegetation is highly sensitive to climate change, which attracted the attention of climate scientists as well as ecologists.

How does grazing exclusion influence plant productivity and community structure in alpine grasslands of the Qinghai-Tibetan Plateau?

open access: yesGlobal Ecology and Conservation, 2020
Grazing exclusion by fencing is a commonly used management practice for restoring the degraded alpine grasslands on the Qinghai-Tibetan Plateau (QTP).

Interactions between carbon and nitrogen dynamics in estimating net primary productivity for potential vegetation in North America [PDF]

open access: yes, 1992
We use the terrestrial ecosystem model (TEM), a process-based model, to investigate how interactions between carbon (C) and nitrogen (N) dynamics affect predictions of net primary productivity (NPP) for potential vegetation in North America. Data on pool

SIVIM Alpine – Database of high-mountain grasslands in the Iberian Peninsula [PDF]

open access: yesVegetation Classification and Survey, 2020
SIVIM Alpine (GIVD ID: EU-00-034) is a thematic database focused on vegetation plots from alpine grasslands of the Iberian Peninsula. The main aim of the database is to centralize historical and new vegetation plots of grassland-like communities above the treeline from Spanish mountains, the Pyrenees (including France and Andorra) and Serra da Estrela (
