Climate change and permafrost thaw are unlocking the vast storage of organic carbon held
in northern frozen soils. Here, we evaluated the effects of thawing ice‐rich permafrost on …

The recognition and discrimination of phytoplankton species is one of the foundations of
freshwater biodiversity research and environmental monitoring. This step is frequently a …

Lakes have a central role in the carbon cycle of the boreal landscape. These systems
typically stratify in summer and their hypolimnetic microbial communities influence burial of …

Stratified lakes and ponds featuring steep oxygen gradients are significant net sources of
greenhouse gases and hotspots in the carbon cycle. Despite their significant biogeochemical …

Although complex cooccurrence patterns have been described for microbes in natural
communities, these patterns have scarcely been interpreted in the context of ecosystem …

Although development of microbiota in childhood has been linked to chronic immune-related
conditions, early childhood determinants of microbiota development have not been fully …

Methylmercury is a potent human neurotoxin which biomagnifies in aquatic food webs. Although
anaerobic microorganisms containing the hgcA gene potentially mediate the formation …

In the subarctic region, climate warming and permafrost thaw are leading to emergence of
ponds and to an increase in mobility of catchment carbon. As carbon of terrestrial origin is …

High levels of nitrogen originating from blasting operations, for example at mining sites or
quarries, risk contaminating water bodies through leaching from waste rock dumps. Woodchip …

Small oxygen-stratified humic lakes of the boreal zone are important sources of methane to
the atmosphere. Although stable isotope profiling has indicated that a substantial part of …
