The ice‐cover period in lakes is increasingly recognized for its distinct combination of
physical and biological phenomena and ecological relevance. Knowledge gaps exist where …

Persistently cold environments constitute one of our world's largest ecosystems, and
microorganisms dominate the biomass and metabolic activity in these extreme …

Ice cover plays a critical role in physical, biogeochemical, and ecological processes in lakes.
Despite its importance, winter limnology remains relatively understudied. Here, we provide a …

Despite their generally isolated geographic locations, the freshwaters of the north are
subjected to a wide spectrum of environmental stressors. High-latitude regions are …

Winter is an important season for many limnological processes, which can range from
biogeochemical transformations to ecological interactions. Interest in the structure and …

Modeling studies examining the effect of lakes on regional and global climate, as well as
studies on the influence of climate variability and change on aquatic ecosystems, are …

Thick ice cover is a feature of cold‐temperate, polar, and alpine lakes and rivers throughout
much of the year. Our observations from Canadian lakes and rivers across the latitudinal …

Climate and cryospheric observations have shown that the high Arctic has experienced
several decades of rapid environmental change, with warming rates well above the global …

While the sentinel nature of freshwater systems is now well recognized, widespread
integration of freshwater processes and patterns into our understanding of broader climate …

Small ice‐covered lakes are stratified by temperature and solutes. Using time series
measurements and profiles of temperature, specific conductance (SC), and dissolved …
