Compared to the well‐studied open water of “growing” season, under‐ice conditions in lakes are characterized by low and rather constant temperature, slow movements, limited light availability, reduced exchange with surrounding landscape. These interact ice‐cover duration shape microbial processes temperate ultimately influence phenology community ecosystem processes. We review current knowledge on microorganisms seasonally frozen lakes. Specifically, we highlight how alter lake physics ways that this can affect distribution metabolism auto‐ heterotrophic microorganisms. identify functional traits hypothesize important for understanding dynamics discuss these species interactions. As ice coverage has already been seen reduce as air temperatures have warmed, microbiome predicting functioning near future.
