The spatial differentiation of alpine wetlands on the eastern Tibetan Plateau using multi-source remote sensing images

Frontiers in Remote Sensing
The alpine wetlands on the eastern Qinghai-Tibet Plateau (EQTP) serve as a critical global ecological barrier. Under the dual pressures of climate change and human activities, these wetland systems face environmental challenges such as retrogressive ...

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 ...

Precipitation-Driven Soil and Vegetation Changes Shape Wetland Greenhouse Gas Emissions [PDF]

Biology
Against the backdrop of global climate change, alterations in precipitation regimes—including the increasing frequency of extreme events—have become more widespread, exerting profound impacts on terrestrial ecosystems and reshaping greenhouse gas (GHG ...

Functional assessment of urban forested wetlands. [PDF]

, 2006
Wetlands perform various functions of vital socio-ecological significance. To avoid further loss of functions, functional assessment techniques for management purposes are important to develop for different wetland classes.

Diversity and Species Richness of Lepidopteran Stemborers and Their Host Plants Across Major Vegetation Mosaics of East Africa. [PDF]

Ecol Evol
Lepidopteran stemborer populations in wild habitats are increasingly influenced by anthropogenic disturbances, including urbanization and agricultural intensification in addition to climate change, which alter community composition and diversity within fragmented native ecosystems.

Groundwater Rise Sustains the World's Largest Alpine Water System Under Global Warming. [PDF]

Adv Sci (Weinh)
Shallow groundwater depth (SGWD) across the non‐permafrost plains of the Qinghai–Xizang Plateau decreased at averagely 0.02 m year−1, adding 31.44 Gt of freshwater storage from 2000 to 2020 and sustaining ∼53 500 km2 of alpine ecosystems. A vadose‐zone capacity of 426.6 Gt reveals these aquifers as promising reservoirs, highlighting groundwater's ...

Long-term persistence and recycling of Bacillus thuringiensis israelensis spores in wetlands sprayed for mosquito control

Ecotoxicology and Environmental Safety, 2022
Bacillus thuringiensis subsp. israelensis (Bti) is the main larvicide used to control mosquitoes worldwide. Although there is accumulating evidence of Bti having environmental effects on non-target fauna, relatively few field studies have documented the ...

Change in grass hill size can signal species diversity changes and ecosystem state transitions during alpine wetland degradation

Ecological Indicators, 2021
The prospect of likely catastrophic transitions in ecosystems requires the development of early warning indicators that will provide advance warnings for undesired transitions.

Tibetan Buddhism, Wetland Transformation, and Environmentalism in Tibetan Pastoral Areas of Western China

Conservation & Society, 2017
Alpine wetlands occupy a considerable area of the Tibetan Plateau, a region that is characterised by diverse but fragile ecosystems, including alpine wetlands, which are reported to have shrunk by 29% over the last several decades.
