Microorganisms in cold ecosystems play a key ecological role in their natural habitats. Since
these ecosystems are especially sensitive to climate changes, as indicated by the worldwide …

Permafrost covers a quarter of the northern hemisphere land surface and contains twice the
amount of carbon that is currently present in the atmosphere. Future climate change is …

Permafrost thawing results in the formation of thermokarst lakes, which are biogeochemical
hotspots in northern landscapes and strong emitters of greenhouse gasses to the …

The vertical structuring of methanotrophic communities and its genetic controllers remain
understudied in the water columns of oxygen-stratified lakes. Therefore, we used 16S rRNA …

Large amounts of carbon sequestered in permafrost on the Tibetan Plateau (TP) are
becoming vulnerable to microbial decomposition in a warming world. However, knowledge …

In the ice‐rich permafrost area of Central Yakutia (Eastern Siberia, Russia), climate warming
and other natural and anthropogenic disturbances have caused permafrost degradation and …

Lake methane (CH4) emissions are largely controlled by aerobic methane‐oxidizing
bacteria (MOB) which mostly belong to the classes Alpha‐and Gammaproteobacteria (Alpha …

Small boreal lakes are known to contribute significantly to global CH 4 emissions. Lake
Lovojärvi is a eutrophic lake in southern Finland with bottom water CH 4 concentrations up …

Salinization of freshwater is increasingly observed in regions where chloride de-icing salts
are applied to the roads in winter, but little is known about the effects on microbial …

Permafrost peatlands are a significant source of methane (CH4) emissions to the
atmosphere and could emit more CH4 with continued permafrost thaw. Aerobic methane …
