Thaw 
This, in turn, provides food and habitat for a variety of
animals, from small rodents to large predators like wolves and bears
...Animals like the
Arctic fox change their diet during the thaw season, shifting from hunting on the snow to foraging for insects and berries in the newly exposed vegetation
...
Effects of Permafrost It is primarily found in polar regions, including the
Arctic and Antarctic, as well as in high-altitude mountainous areas
...Many species of
animals, such as Arctic foxes, caribou, and lemmings, rely on the frozen ground for shelter and protection from predators
...
Ecosystem Functions and Tundra Biodiversity Overview of Tundra Biome The tundra biome is found in the
Arctic, Antarctic, and high mountain regions around the world
...Some of the iconic
animals found in tundras include caribou, musk oxen, Arctic foxes, and polar bears
...
Effect of Seasonal Changes on Tundras Tundras are vast, treeless landscapes found in the
Arctic and alpine regions of the world
...The landscape is covered in snow and ice, creating a challenging environment for plants and
animals ...
Seasonal Variability Tundra Species such as caribou,
Arctic foxes, and polar bears are able to withstand the cold temperatures and scarcity of food in the tundra
...Many of these
animals have thick fur or blubber to help them retain heat
...
Cold Desert Adaptation Examples Despite the harsh conditions, many plants and
animals have evolved remarkable adaptations to survive in these challenging environments
...Some notable examples include:
Arctic Fox: These small mammals have thick fur coats that provide insulation against the cold
...
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
...These adaptations allow plants and
animals to thrive in the extreme cold and limited growing season of tundras
...
Seasonal Vegetation Common species of mosses in the tundra include
Arctic moss, reindeer moss, and feather moss
...These plants provide food and shelter for a variety of
animals, including herbivores such as caribou and musk oxen
...
Human Impact on Tundras Tundras are vast, treeless landscapes found in the
Arctic and high mountain regions characterized by low temperatures and a short growing season
...Overgrazing: Grazing by domestic
animals can damage tundra vegetation, leading to soil erosion and loss of biodiversity
...
Role of Snow Cover in Tundra Insulation and Protection For many tundra plants and
animals, snow cover provides a protective layer against the harsh winter conditions
...Table: Snow Cover in Different Tundra Regions Tundra Region Snow Cover Duration Snow Depth
Arctic Tundra 8-10 months 30-60 cm Alpine Tundra 6-8 months 20-40 cm Antarctic Tundra 12-14 months 50-100 cm
