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 ...

Does wetland degradation impact bird diversity differently across seasons? A case study of Zoige Alpine Wetland ecosystem

Avian Research, 2023
Wetland degradation is an escalating global challenge with profound impacts on animal diversity, particularly during successional processes. Birds, as highly mobile and environmentally sensitive organisms, serve as effective indicators of ecological ...

Seasonality and Vertical Structure of Microbial Communities in Alpine Wetlands. [PDF]

Microorganisms
The soil microbial community plays a crucial role in the elemental cycling and energy flow within wetland ecosystems. The temporal dynamics and spatial distribution of soil microbial communities are central topics in ecology. While numerous studies have focused on wetland microbial community structures at low altitudes, microbial diversity across ...

Holocene geochemical footprint from Semi-arid alpine wetlands in southern Spain [PDF]

Scientific Data, 2018
AbstractHere we provide the geochemical dataset that our research group has collected after 10 years of investigation in the Sierra Nevada National Park in southern Spain. These data come from Holocene sedimentary records from four alpine sites (ranging from ∼2500 to ∼3000 masl): two peatlands and two shallow lakes.

Spatial–Temporal Heterogeneity of Wetlands in the Alpine Mountains of the Shule River Basin on the Northeastern Edge of the Qinghai–Tibet Plateau [PDF]

Remote Sensing
Alpine wetland ecosystems, as important carbon sinks and water conservation areas, possess unique ecological functions. Driven by climate change and human activities, the spatial distribution changes in alpine wetlands directly affect the ecosystems and ...

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 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 ...

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 ...
