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 ...

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.

Alpine constructed wetlands: A metagenomic analysis reveals microbial complementary structure

Science of The Total Environment, 2022
Constructed wetlands (CWs) are used to water treatment worldwide, however their application at high-altitude is poorly studied. In order to survive mountain winters, CWs rely on native flora and associated microbial communities. However, the choice of plant-microbes pairs more suitable for water treatment is challenging in alpine environments.

Drivers of Soil Total Nitrogen and Phosphorus Storage in Alpine Wetland Across the Three Rivers Source Region on the Qinghai-Tibetan Plateau

Frontiers in Environmental Science, 2022
Although soil total nitrogen (STN) and soil total phosphorus (STP) play significant roles in terrestrial ecosystem function, their storage and driving factors in the alpine wetlands of the Qinghai-Tibetan Plateau remain unclear.

Seasonality and vertical structure of microbial communities in the alpine wetland

, 2023
Abstract The soil microbial community plays an important role in wetland ecosystem material transformation and energy flow. The temporal dynamics and spatial distribution of soil microbial communities have always been central questions in ecology.

Tussock microhabitats increase nitrogen uptake by plants in an alpine wetland

Plant and Soil, 2021
Tussock microhabitat is a universal phenomenon in wetlands, where soil and plant properties differ from their surrounding lawns. This study aims to investigate the differences of plant nitrogen (N) uptake between tussocks and lawns, which would further affect ecosystem functions.

Soil Water Content Shapes Microbial Community Along Gradients of Wetland Degradation on the Tibetan Plateau

Frontiers in Microbiology, 2022
Soil microbes are important components in element cycling and nutrient supply for the development of alpine ecosystems. However, the development of microbial community compositions and networks in the context of alpine wetland degradation is unclear.

Monitoring the Seasonal Hydrology of Alpine Wetlands in Response to Snow Cover Dynamics and Summer Climate: A Novel Approach with Sentinel-2

Remote Sensing, 2020
Climate change in the European Alps during recent years has led to decreased snow cover duration as well as increases in the frequency and intensity of summer heat waves.

Streptomyces paludis sp. nov., isolated from an alpine wetland soil

International Journal of Systematic and Evolutionary Microbiology, 2020
A Gram-stain-positive actinobacterium, designated strain GSSD-12T, was isolated from an alpine wetland soil. blast search of the full-length 16S rRNA gene sequence of GSSD-12T indicated it represented a member of the genus Streptomyces , and displayed highest ...

Effects of water level on three wetlands soil seed banks on the Tibetan Plateau. [PDF]

PLoS ONE, 2014
BACKGROUND: Although the effect of water level on germination in soil seed banks has been documented in many ecosystems, the mechanism is not fully understood, and to date no empirical studies on this subject exist.
