Nitrogen dynamics of alpine swamp meadows are less responsive to climate warming than that of alpine meadows

Science of The Total Environment
The freeze-thaw cycle mediates permafrost soil hydrothermal status, nitrogen (N) mineralization, and loss. Furthermore, it affects root development and competition among nitrophilic and other species, shaping the pattern of N distribution in alpine ecosystems.

The phytosociology of some alpine meadows in N.W. Himalayas

Vegetatio, 1971
Phytosociological studies of certain meadows occurring above the tree line in N.W. Himalayas have been made. A close relationship of the ground cover with moisture, the thickness of soil cover and the amount and retention period of snow has been observed.

Nitrogen deposition and carbon sequestration in alpine meadows

Biogeochemistry, 2004
Nitrogen deposition experiments were carried out in alpine meadow ecosystems in Qinghai-Xizang Plateau in China, in order to explore the contribution of nitrogen deposition to carbon sequestration in alpine meadows. Two methods were used in this respect. First, we used the allocation of 15 N tracer to soil and plant pools.

Drought limits alpine meadow productivity in northern Tibet

Agricultural and Forest Meteorology, 2021
Abstract Under global climate change, warmer temperatures and changing precipitation patterns will increase the relative importance of soil and atmospheric droughts in limiting productivities across different ecosystems, especially in the fragile and sensitive ecosystem on the Tibetan Plateau.

Grazing affects methanotroph activity and diversity in an alpine meadow soil

Environmental Microbiology Reports, 2009
Summary The role of methane‐oxidizing bacteria (MOB) in alpine environments is poorly understood, but is of importance given the abundance of alpine environments and the role of MOB in the global carbon cycle. Using a combination of approaches we examined both seasonal and land usage effects on the ecology of ...

Of Men and Meadows: Strategies of Alpine Land Use

Anthropological Quarterly, 1972
Mountain villages in southern Switzerland traditionally met their subsistence needs through mixed farming and herding within the environmental constraints imposed by altitude, topography, exposure to sun, and water availability. Community boundaries were clearly defined and historically stable. Exploitative technology varied little through time.

Primary Productivity of Alpine Meadow Communities

1975
The plant biomass and the production of tundra areas may vary strongly between plant communities (Bliss, 1962; Rodin and Bazilevich, 1967; Wielgolaski and Rosswall, 1972; Brzoska, 1973; Bliss and Wielgolaski, 1973; Perkins et al., 1975), and also between years.

Carbon balance of yak ranch in alpine meadow

Carbon Footprints
Livestock husbandry is a primary anthropogenic source of global greenhouse gas (GHG) emissions. The Qinghai-Tibetan Plateau (QTP), an important geography for animal husbandry in China, and is therefore a significant contributor to the global GHG budget.

Breeding birds from reedbeds to alpine meadows

Hydrobiologia, 1997
The fauna of passerines (Passeriformes) and other bird families (Galliformes, Columbiformes, Cuculiformes, Coraciiformes and Piciformes) censused with similar methods, was examined; 132 species of the above families have been observed in the Prespa area. Of these, 19 non-passerines and 77 passerines breed.
