Why tundra soil is poor in nutrients

Tundra Soils. Breadcrumb Home. Climate of the Tundra In order to be a Gelisol, permafrost needs to be within cm of the soil surface. Organisms Did you know that the largest portion of soil organic matter in the world is located in the tundra? Relief and Parent Material Most of the soils in the tundra were formed with mixed rock fragments and sediments left behind by the glaciers when they receded.

Time Most of these soils are very young, and were covered by glaciers until 10, years ago. Special Issues in the Tundra Because the soils of the tundra freeze, thaw, and stir, there are many unique building problems that can occur.

Tundra wildlife includes small mammals—such as Norway lemmings Lemmus lemmus , arctic hares Lepis arcticus , and arctic ground squirrels Spermophilus parryii —and large mammals, such as caribou Rangifer tarandus.

These animals build up stores of fat to sustain and insulate them through the winter. They also have thick coats of fur for further insulation. Some save energy by hibernating during the long winter months. Others migrate to warmer climes during winter.

Many birds also migrate into the tundra during the growing season to feed, mate, and nest. Atop the food chain are tundra carnivores, such as arctic foxes Vulpes lagopus , arctic wolves Canis lupus , snowy owls Bubo scandiaca , and polar bears Ursus maritimus , which move into the tundra during the summer when prey is plentiful and their usual hunting grounds on sea ice diminish.

Many animals, both predator and prey, develop white fur or feathers in the winter months for camouflage in ice and snow. Tundra insects have also developed adaptations for the cold; mosquitoes Aedes nigripes , for example, have a chemical compound that acts as antifreeze, lowering the freezing temperature in their bodily fluids. Though the tundra is remote, it is increasingly threatened as people encroach on it to build or drill for oil, for example.

Perhaps the greatest danger, however, comes from climate change. Warming temperatures could disrupt the cold tundra biome and the life in it, as well as thaw its underlying permafrost, releasing greenhouse gases that would further accelerate global warming.
