Examples of arctic tundra in the following topics:

  • Boreal Forests and Arctic Tundra

    • The Arctic tundra, lying north of the subarctic boreal forest, is located throughout the Arctic regions of the northern hemisphere .
    • Plants in the arctic tundra have a very short growing season of approximately 10–12 weeks.
    • Plants in the Arctic tundra are generally low to the ground .
    • The soils of the Arctic tundra may remain in a perennially frozen state referred to as permafrost.
    • Notable animals in the Arctic tundra include caribou (reindeer ), musk ox, arctic hare, arctic fox, snowy owl, lemmings, and polar bears.

  • Biogeography

    • These deciduous forests give way to the boreal forests found in the subarctic, the area south of the Arctic Circle.
    • Finally, you would reach the Arctic tundra, which is found at the most northern latitudes.

  • Characteristics of the Animal Body

    • The arctic fox is an example of a complex animal that has adapted to its environment and illustrates the relationships between an animal's form and function .
    • An arctic fox is a complex animal, well adapted to its environment.

  • Mosses

    • Their habitats vary from the tundra, where they are the main vegetation, to the understory of tropical forests.
    • In the tundra, the mosses' shallow rhizoids allow them to fasten to a substrate without penetrating the frozen soil.

  • Agricultural Diversity

    • The seed vault is located deep into the rock of an arctic island.
    • Conditions within the vault are maintained at ideal temperature and humidity for seed survival, but the deep underground location of the vault in the arctic means that failure of the vault's systems will not compromise the climatic conditions inside the vault.
    • The Svalbard Global Seed Vault is a protected storage facility in the arctic for seeds of earth's diverse crops.

  • Bryophytes

    • They constitute the major flora of inhospitable environments like the tundra where their small size and tolerance to desiccation offer distinct advantages.

  • What constitutes a biome?

    • The major types of biomes include: aquatic, desert, forest, grassland, savannas, and tundra.

  • Temperature and Water

    • In migration, for instance, the arctic tern (Sterna paradisaea) makes a 40,000 km (24,000 mi) round trip flight each year between its feeding grounds in the southern hemisphere and its breeding grounds in the Arctic Ocean .
    • The arctic tern is an example of a species that must migrate yearly to deal with temperature fluctuations that exist in the regions where it is found.

  • The Importance of Seedless Vascular Plants

    • In a hostile environment, such as the tundra where the soil is frozen, bryophytes grow well because they do not have roots and can dry and rehydrate rapidly once water is again available.
    • Mosses are at the base of the food chain in the tundra biome.
