Decoupling of alpine wetland degradation and regional development

Ecological Indicators
Wetland is the core functional system of the global alpine region. However, with the development of the social economy in the past few decades, the alpine wetland ecosystem has suffered serious shrinkage, drying, degradation and landscape fragmentation ...

Response of soil bacterial community to alpine wetland degradation in arid Central Asia. [PDF]

Front Plant Sci, 2022
A large number of studies have reported the importance of bacterial communities in ecosystems and their responses to soil degradation, but the response mechanism in arid alpine wetlands is still unclear. Here, the non-degraded (ND), slightly degraded (SD), and heavily degraded (HD) regions of Bayinbuluk alpine wetland were used to analyzed the ...

Diversity of Trichoderma species associated with soil in the Zoige alpine wetland of Southwest China. [PDF]

Sci Rep, 2022
AbstractThe ecology of soil fungi is poorly understood, and recent comprehensive reports on Trichoderma are unavailable for any region, including the Zoige alpine wetland ecological region in China. One hundred soil samples were collected from different soil types and soil layers in Zoige alpine wetland ecological regions.

Iron-mediated soil carbon response to water-table decline in an alpine wetland. [PDF]

Nat Commun, 2017
AbstractThe tremendous reservoir of soil organic carbon (SOC) in wetlands is being threatened by water-table decline (WTD) globally. However, the SOC response to WTD remains highly uncertain. Here we examine the under-investigated role of iron (Fe) in mediating soil enzyme activity and lignin stabilization in a mesocosm WTD experiment in an alpine ...

Response Characteristics and Community Assembly Mechanisms of nirS-Type Denitrifiers in the Alpine Wetland under Simulated Precipitation Conditions [PDF]

Biology
The nitrogen cycling process in alpine wetlands is profoundly affected by precipitation changes, yet the dynamic response mechanism of denitrifiers to long-term precipitation shifts in the alpine wetland of the Qinghai-Tibet Plateau remains enigmatic ...

Fluxes of methane, carbon dioxide and nitrous oxide in an alpine wetland and an alpine grassland of the Tianshan Mountains, China [PDF]

Journal of Arid Land, 2014
Methane (CH4), carbon dioxide (CO2) and nitrous oxide (N2O) are known to be major greenhouse gases that contribute to global warming. To identify the flux dynamics of these greenhouse gases is, therefore, of great significance. In this paper, we conducted a comparative study on an alpine grassland and alpine wetland at the Bayinbuluk Grassland Eco ...

Changes in alpine wetland ecosystems of the Qinghai–Tibetan plateau from 1967 to 2004 [PDF]

Environmental Monitoring and Assessment, 2010
Spatiotemporal shifts in the extent and distribution of alpine wetland ecosystems in China's Qinghai-Tibet plateau were investigated for the period 1967-2004. Using aerial photographs for 1967, and satellite remote sensing data for 1986, 2000, and 2004/5, the main components and distribution of alpine wetland ecosystems in the headwaters regions of the
