Thermokarst (thaw) lakes of permafrost peatlands are among the most important sentinels of climate change and sizable contributors of greenhouse gas emissions (GHG) in high latitudes. These lakes are humic, often acidic and exhibit fast growing/drainage depending on the local environmental and permafrost thaw. In contrast to good knowledge of the thermokarst lake water hydrochemistry and GHG fluxes, the sediments pore waters remain virtually unknown, despite the fact that these are hot spots of biogeochemical processes including GHG generation.

Article Synopsis
- The study investigates zooplankton communities in humic thermokarst lakes of Western Siberia, focusing on their diversity and abundance across different permafrost zones and seasons.
- Sampling 69 lakes, researchers identified 74 zooplankton species, with species richness increasing towards the northern continuous permafrost zone, while the number of species per lake decreased, particularly for cladocerans.
- Environmental factors like water temperature, lake area, depth, pH, and dissolved carbon were found to significantly influence zooplankton abundance and diversity, exhibiting seasonal variations in relationships for different zooplankton groups.
