The successful colonization of new habitats has played a fundamental role during the
evolution of life. Salinity is one of the strongest barriers for organisms to cross, which has …

Small lentic freshwater ecosystems play a disproportionate role in global biogeochemical
cycles by processing large amounts of carbon (C), nitrogen (N), and phosphorus (P), but it is …

Thermokarst ponds (thaw lakes) are ubiquitous in northern landscapes. They are hotspots
for the biogeochemical processing of elements, such as carbon (C), nitrogen (N), sulfur (S) …

Northern lakes disproportionately influence the global carbon cycle, and may do so more in
the future depending on how their microbial communities respond to climate warming …

Permafrost peatlands, containing a sizable amount of soil organic carbon (OC), play a
pivotal role in soil (peat) OC transformation into soluble and volatile forms and greatly …

Permafrost thaw in continental lowlands produces large number of thermokarst (thaw) lakes,
which act as a major regulator of carbon (C) storage in sediments and C emission in the …

It has been well documented that agricultural activities lead to significant alterations in
surface water dissolved organic matter (DOM), yet their impacts on groundwater DOM …

Thermokarst lakes and ponds formed due to thawing of frozen peat in high-latitude lowlands
are very dynamic and environmentally important aquatic systems that play a key role in …

Arctic regions contain large amounts of organic carbon (OC) trapped in soil and wetland
permafrost. With climate warming, part of this OC is released to aquatic systems and …

Climate change–driven permafrost thaw has a strong influence on pan‐Arctic regions, via,
for example, the formation of thermokarst ponds. These ponds are hotspots of microbial …
