Study on the Relationship between Dry and Wet Changes and the Transition Zone of Alpine Meadow and Alpine Grassland in Northern Xizang

open access: yesGaoyuan qixiang, 2023
Based on vegetation type map, leaf area index and meteorological data for northern Xizang from 1990 to 2019, the relationship between the transition zone of alpine meadow and alpine grassland in northern Xizang and dry-wet climate boundary (1.5 on the ...

Snow-vegetation-atmosphere interactions in alpine tundra

open access: yesBiogeosciences, 2023
Abstract. The interannual variability of snow cover in alpine areas is increasing, which may affect the tightly coupled cycles of carbon and water through snow-vegetation-atmosphere interactions across a range of spatio-temporal scales. To explore the role of snow cover for the land-atmosphere exchange of CO2 and water vapor in alpine tundra ecosystems,

Quantitative Assessment of the Impact of Physical and Anthropogenic Factors on Vegetation Spatial-Temporal Variation in Northern Tibet

open access: yesRemote Sensing, 2019
The alpine grassland on the Qinghai-Tibet Plateau covers an area of about 1/3 of China’s total grassland area and plays a crucial role in regulating grassland ecological functions.

Ecosystem-Dependent Responses of Vegetation Coverage on the Tibetan Plateau to Climate Factors and Their Lag Periods

open access: yesISPRS International Journal of Geo-Information, 2021
The spatiotemporal variation characteristics of the Normalized Difference Vegetation Index (NDVI) and its climate response patterns are of significance in deepening our understanding of regional vegetation and climate change.

Data on alpine grassland diversity in Gran Paradiso National Park, Italy

open access: yesData in Brief, 2019
The diversity of alpine grassland species and their functional traits constitute alpine ecosystem functioning and services that support human-wellbeing. However, alpine grassland diversity is threatened by land use and climate change.

Unexpected impacts of climate change on alpine vegetation [PDF]

open access: yesFrontiers in Ecology and the Environment, 2007
The vegetation in a high alpine site of the European Alps experienced changes in area between 1953 and 2003 as a result of climate change. Shrubs showed rapid expansion rates of 5.6% per decade at altitudes between 2400 m and 2500 m. Above 2500 m, vegetation coverage exhibited unexpected patterns of regression associated with increased precipitation ...

Impact of broom, Cytisus scoparius (Fabaceae), in naturally treeless sub-alpine frost-hollow vegetation communities at the Barrington Tops, south-eastern Australia [PDF]

open access: yes, 2013
The exotic shrub Cytisus scoparius (L.) Link (family Fabaceae), known as broom, is having a major impact on native vegetation in naturally treeless sub-alpine frost-hollow areas (c. 32o 01’ 37” S, 151o 26’ 12” E’, 1440 m elevation) at the Barrington Tops,

Influence of Anthropogenic Activities and Major Natural Factors on Vegetation Changes in Global Alpine Regions

open access: yesLand, 2022
Understanding vegetation changes and their driving forces in global alpine areas is critical in the context of climate change. We aimed to reveal the changing trend in global alpine vegetation from 1981 to 2015 using the least squares regression method ...
