Vegetation Types in the Tundra There are two main types of tundra vegetation:
Arctic tundra and alpine tundra
...
Human-Induced Changes in Tundra Ecosystems Overview The tundra biome is found in the
Arctic and alpine regions of the world, covering approximately 10% of the Earth's surface
...Tundra ecosystems are home to species such as caribou, musk oxen, Arctic
foxes, and a variety of migratory birds
...
Permafrost Changes remains continuously frozen for at least two consecutive years, and can be found in regions with cold climates such as the
Arctic, Antarctic, and high mountain ranges
...
Ecosystems These ecosystems are typically located in the
Arctic and Antarctic regions, as well as at high altitudes in mountain ranges
...Animals such as reindeer, Arctic
foxes, polar bears, and migratory birds are common inhabitants of tundra ecosystems
...
Tundra Soil and Climate Some common adaptations include:
Arctic Moss: A low-growing plant that can survive in nutrient-poor soil by absorbing nutrients directly from the atmosphere
...
Vegetation Patterns Some of the common vegetation zones in tundras include: Zone Description Low
Arctic Tundra Characterized by low-lying shrubs and mosses, this zone is found at lower altitudes
...
Influence of Ice Sheets on Tundras Ice sheets are typically found in polar regions, such as the
Arctic and Antarctic, where temperatures are consistently low enough to sustain their growth
...Adaptation Arctic Willow Low-growing stature to avoid wind damage and conserve heat Arctic
Fox Thick fur coat for insulation and camouflage in snowy environments Caribou Migratory behavior to follow food sources and avoid harsh winter conditions
...
Seasonal Changes in Tundras Tundras are vast, treeless regions found in the
Arctic and alpine regions of the world
...Arctic
fox: A small mammal with thick fur that changes color with the seasons for camouflage
...
Human-Induced Impacts on Tundra Environments Overview of Tundra Environments Tundras are found in high-latitude regions near the
Arctic and Antarctic circles, as well as at high elevations in mountainous areas
...Tundra vegetation typically consists of mosses, lichens, grasses, and low shrubs, while animals such as caribou, Arctic
foxes, and polar bears inhabit these regions
...
Seasonal Vegetation Common species of mosses in the tundra include
Arctic moss, reindeer moss, and feather moss
