Alpine wetland degradation reduces carbon sequestration in the Zoige Plateau, China

Frontiers in Ecology and Evolution, 2022
Alpine wetland plays an important role in the global carbon balance but are experiencing severe degradation under climate change and human activities.

Diversity of Trichoderma species associated with soil in the Zoige alpine wetland of Southwest China

Scientific Reports, 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.

Increase in plant productivity in the tundra in Sweden is not related to increasing presence of warm‐adapted vascular plant species

Ecography, EarlyView.
Over the past decades, Arctic and alpine biomes have warmed faster than the global average. Substantial vegetation changes have been reported as a response to this warming, including increased productivity and the spread of warm‐adapted (thermophilic) species that are less resistant to grazing pressure into higher latitudes and altitudes.

Impacts of Permafrost Degradation on Hydrology and Vegetation in the Source Area of the Yellow River on Northeastern Qinghai-Tibet Plateau, Southwest China

Frontiers in Earth Science, 2022
Under a persistent warming climate and increasing human activities, permafrost in the Source Area of the Yellow River (SAYR) has been degrading regionally, resulting in many eco-environmental problems.

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 ...

Stochastic and deterministic processes influencing mountain mire diatom communities across spatial scales

Ecography, EarlyView.
Understanding how deterministic and stochastic processes influence the shape of microorganism community assembly across different spatial scales is essential for disentangling biodiversity patterns. Mires are nutrient‐poor and heterogeneous wetlands that form isolated habitats supporting highly diverse diatom assemblages, particularly in mountainous ...

The dual influence of top‐down and bottom‐up processes on a mesopredator and the consequences for prey

Ecography, EarlyView.
Ecosystem dynamics are shaped by interacting top‐down and bottom‐up processes, yet their relative importance may vary through time following disturbances such as disease outbreaks and changes in apex predator communities. Using a 52‐year time series in south‐central Sweden, we examined how disease, apex predators, and prey availability jointly impact a

Interplay of soil characteristics and arbuscular mycorrhizal fungi diversity in alpine wetland restoration and carbon stabilization

Frontiers in Microbiology
Alpine wetlands are critical ecosystems for global carbon (C) cycling and climate change mitigation. Ecological restoration projects for alpine grazing wetlands are urgently needed, especially due to their critical role as carbon (C) sinks.

Alpine Secondary Forest Types Influence Soil Microbial Community Structure and Enzyme Activities on the Eastern Qinghai–Tibet Plateau

Land Degradation &Development, EarlyView.
ABSTRACT Soil microbial communities and enzyme activities influence soil functions and tree growth in ecologically fragile alpine regions. However, differences in soil microbial communities among secondary forests remain poorly understood in the Qinghai–Tibet Plateau.

Greening and Divergent Stability Responses in Central Asian Mountain Grasslands Under the Grassland Ecological Compensation Policy of China

Land Degradation &Development, EarlyView.
ABSTRACT Mountain grasslands of Central Asia, recognized as a globally significant biodiversity hotspot and a vital pastoral resource, are presently experiencing profound transformations driven by climate change and evolving grazing practices. This study investigated the multidimensional dynamics of ecosystem stability in the Bayinbuluk grassland of ...
