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 influences biomass production and protein content of alpine meadows

Science of The Total Environment, 2022
Alpine grasslands are essential for carbon sequestration and food supply for domestic and wild herbivores inhabiting mountainous areas worldwide. These biomes, however, are alternatively threatened by the abandonment of agricultural and livestock practices leading to a fast-growing shrubification process while other mountain grasslands are suffering ...

Understanding Alpine Meadow Ecosystems

2016
This chapter introduces the alpine meadow and its distribution in the headwater region of the Yellow River, including subtypes of alpine meadow, species composition and productivity, soil types and their properties. Various views on causes of grassland degradation are summarized.

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.

Linkage between species traits and plant phenology in an alpine meadow

Oecologia, 2021
Plant phenology differs largely among coexisting species within communities that share similar habitat conditions. However, the factors explaining such phenological diversity of plants have not been fully investigated. We hypothesize that species traits, including leaf mass per area (LMA), seed mass, stem tissue mass density (STD), maximum plant height

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.

Grazing alters the relationship between alpine meadow biodiversity and ecosystem multifunctionality

Science of The Total Environment, 2023
The relationship between biodiversity and ecosystem multifunctionality (EMF) depends on changes in environmental disturbance. Plant and soil biological diversity can mediate EMF, but how these change in response to grazing disturbance remains unknown. Here we present an 8-year experiment on sheep grazing control in alpine grasslands in Gannan Tibetan ...

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.

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.

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.
