A soft, thick coat of snow makes a lot of the world seem to slow down or even stop — at least temporarily. The fluffy piles absorb sound and make the world quiet and still. But deep underneath, in pockets between the snow and the ground, life goes on. This is the subnivium, a tiny ecosystem all its own.
Here under the white stuff, roots, small mammals, microbes, insects and even birds thrive. They use the subnivium to make the most of the winter months — hunting, breeding, breaking down leaves and more. All those cold-weather activities help determine which plants and animals will thrive during the snow-free seasons.
