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.

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 ...

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.

Uneven distributions of unique species promoting N niche complementarity explain the stability of degraded alpine meadow

Science of the Total Environment
Alpine meadow degradation, usually involving decreased soil nitrogen (N) and patchy landscapes, is a challenge for natural restoration. However, the mechanism underlying plant species coexistence under degradation is unclear.

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.

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.

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.

[Ecomorphological explanations of passerines coexistence in alpine meadow].

Dong wu xue yan jiu = Zoological research, 2014
Species ecomorphological characteristics are the evolutionary results of selective pressures that have enabled individuals of a given species to survive and reproduce. Closely related species co-occurring in homogeneous environments should be morphologically distinct to partition limited resources, so as to minimize interspecific competition. From 1983

USING OF ALPINE MEADOW'S FARMS FOR THE ORGANIZATION OF HIKING ON THE ALPINE MEADOWS OF THE CHORNOHORA MASSIF OF THE UKRAINIAN CARPATHIANS

2019
High mountain farming is a traditional branch of traditional economy of Hutsulshchyna’s region. Original tradition of farming, developed over the centuries, difficult weather conditions and working conditions have formed the unique culture of high mountain farming.
