Permanent ice cover by glaciers and snowfields is a dominant physical force in mountain ecosystems. From an ecological perspective, constant ice cover places harsh controls on life including cold temperature, limited nutrient availability, and often prolonged darkness due to snow cover for much of the year. Despite these limitations, glaciers, and perennial snowfields support diverse, primarily microbial communities. In a new review, postdoc in the lab Scott Hotaling and colleagues we synthesize existing knowledge of ecological stoichiometry, nutrient availability, and food webs in the mountain cryosphere (specifically glaciers and perennial snowfields).
