Changes in the Distribution of Thermokarst Lakes on the Qinghai-Tibet Plateau From 2015 to 2020
Remote SensingThermokarst lakes are widely distributed on the Qinghai-Tibet Plateau (QTP). However, owing to the lack of high-precision remote sensing imagery and the difficulty of in situ monitoring of permafrost regions, quantifying the changes in the distribution ...

Accelerating thermokarst lake changes on the Qinghai–Tibetan Plateau [PDF]
Scientific ReportsAs significant evidence of ice-rich permafrost degradation due to climate warming, thermokarst lake was developing and undergoing substantial changes. Thermokarst lake was an essential ecosystem component, which significantly impacted the global carbon ...

Microbial assemblages in Arctic coastal thermokarst lakes and lagoons. [PDF]
FEMS Microbiol EcolAbstract Several studies have investigated changes in microbial community composition in thawing permafrost landscapes, but microbial assemblages in the transient ecosystems of the Arctic coastline remain poorly understood. Thermokarst lakes, abrupt permafrost thaw features, are widespread along the pan-Arctic coast and transform into ...

Research Progress on Effects of Thermokarst Lakes on Soil Carbon and Microbial Community
Shuitu baochi tongbao, 2022 [Objective] The impacts of thermokarst lakes formed by rapid thawing and collapsing of permafrost on soil carbon and microorganisms were studied in order to provide a reference for the study of ecological environment and greenhouse gas emissions in such ...

Abundant and Rare Bacterial Taxa Structuring Differently in Sediment and Water in Thermokarst Lakes in the Yellow River Source Area, Qinghai-Tibet Plateau [PDF]
Frontiers in Microbiology, 2022 Thermokarst lakes are forming from permafrost thaw and are severely affected by accelerating climate change. Sediment and water in these lakes are distinct habitats but closely connected. However, our understanding of the differences and linkages between

Spatial analyses of thermokarst lakes and basins in Yedoma landscapes of the Lena Delta [PDF]
The Cryosphere, 2011 Distinctive periglacial landscapes have formed in late-Pleistocene ice-rich permafrost deposits (Ice Complex) of northern Yakutia, Siberia. Thermokarst lakes and thermokarst basins alternate with ice-rich Yedoma uplands.

Rare bacterial biosphere is more environmental controlled and deterministically governed than abundant one in sediment of thermokarst lakes across the Qinghai-Tibet Plateau [PDF]
Frontiers in Microbiology, 2022 Thermokarst lakes are widely distributed in cold regions as a result of ice-rich permafrost thaw. Disentangling the biogeography of abundant and rare microbes is essential to understanding the environmental influences, assembly mechanisms, and responses ...

Tracking lake drainage events and drained lake basin vegetation dynamics across the Arctic [PDF]
Nature Communications, 2023 Widespread lake drainage can lead to large-scale drying in Arctic lake-rich areas, affecting hydrology, ecosystems and permafrost carbon dynamics. To date, the spatio-temporal distribution, driving factors, and post-drainage dynamics of lake drainage ...
