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

Photo-produced aromatic compounds stimulate microbial degradation of dissolved organic carbon in thermokarst lakes [PDF]

Nature Communications, 2023
Photochemical and biological degradation of dissolved organic carbon (DOC) and their interactions jointly contribute to the carbon dioxide released from surface waters in permafrost regions.

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 ...

Characteristics of methane emissions from alpine thermokarst lakes on the Tibetan Plateau [PDF]

Nature Communications, 2023
Understanding methane (CH4) emission from thermokarst lakes is crucial for predicting the impacts of abrupt thaw on the permafrost carbon-climate feedback. However, observational evidence, especially from high-altitude permafrost regions, is still scarce.

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 ...

Chemoautotrophic carbon fixation in thermokarst lakes on the Tibetan Plateau [PDF]

Nature Communications
Dissolved organic carbon (DOC) derived from thermokarst lakes is usually considered to be prone to microbial degradation and releases substantial carbon dioxide to the atmosphere, potentially enhancing the positive permafrost carbon (C)-climate feedback.

Thermokarst lake drainage halves the temperature sensitivity of CH4 release on the Qinghai-Tibet Plateau [PDF]

Nature Communications
Thermokarst lakes as hot spots of methane (CH4) release are crucial for predicting permafrost carbon feedback to global warming. These lakes are suffering from serious drainage events, however, the impacts of lake drainage on CH4 release remain unclear ...
