Alaskan Tundra Interesting Facts How Do Animals Adapt To Living In The Tundra?
The tundra is home to extraordinary life that is able to withstand the harsh, beneath zero temperatures of the wintery biome. Animals that alive in the tundra accept unique adaptations that help them survive.
Although there are non nearly equally many animal species in the tundra biome as others, there is even so an affluence of life that thrives in the frigid environment. In this commodity, we'll discuss the different animal species that are able to brand do with the tundra conditions.
What is a Tundra?
The tundra is the coldest biome and experiences harsh winter conditions with temperatures that drop beneath zero. During the summertime, tundra biomes turn into boggy wetlands from melted ice and snowfall.
The tundra biome typically receives no more 10 inches (25 cm) of precipitation per year, which means the tundra is likewise considered a desert. Tundra soil is permafrost, which is a layer of frozen ground underneath the land that prevents plant and tree growth.
Permafrost is caused past long-term below freezing temperatures that do non rise long enough for the underlying ground to thaw. Low-lying grasses and plants are able to abound in the tundra due to adaptations that allow them to sprout quickly in the short summertime months and provide a source of nutrient for many animal species.
3 Types of Tundra Biomes
There are 3 types of tundra biomes.
- Arctic tundra
- Alpine tundra
- Antarctic tundra
1. Arctic Tundra
The Arctic tundra is located above the Arctic Circle in the northernmost part of the Earth. There are 8 countries that take land inside the Arctic Circle, including:
- Canada
- U.s.
- Greenland
- Republic of iceland
- Norway
- Sweden
- Finland
- Russia
Temperatures in the Arctic tundra can achieve as low equally -30 degrees Fahrenheit (-34 degrees Celsius). The tundra has a brusque growing season that just lasts around two months. Animals such as the Arctic play a trick on, polar bears, Arctic wolves, lemmings, and Arctic bumblebees alive in the Arctic tundra.
2. Alpine Tundra
The tall tundra is fairly dissimilar from the Arctic tundra equally the alpine tundra biome is located atop mountains at very high altitudes where temperatures drop dramatically. Smaller trees and other vegetation are more than arable in this biome.
Animate being species, such every bit the Himalayan Tahr and Snow Leopard, have adjusted to the below-freezing temperatures and rugged terrain of the mountains in the alpine tundra.
3. Antarctic Tundra
The continent of Antarctica and sub-Antarctic islands located betwixt Antarctica and the coasts of Commonwealth of australia and New Zealand make up the Antarctic tundra. Although it is inhospitable to humans, scientists take ready up research stations to study the area and wildlife.
Despite its uninhabitable characteristics, various species of penguins, seals, birds, whales, and fish alive in the Antarctic biome. Much of Antarctic wild fauna depends on sea life for food every bit there are simply two plant species, Antarctic hair grass and Antarctic pearlwort, that inhabit the biome due to permanent ice and snowfall coverage.

1. Arctic Wolf (Canis lupus arctos)
The majestic Chill Wolf resides in the Arctic region of North America and Greenland. Older Arctic wolves are all-white in colour with younger wolves having a smokey-gray and white coloration.
Chill wolves tend to be smaller than gray wolves, just can weigh up to 175 pounds (79.iv kilograms). They tend to exist solitary animals, but may also alive in packs.
Since Arctic wolves cannot bury dens due to permafrost, they observe caves, rock outcroppings, or depressions in the ground to give nativity. 2 to 3 pups can be born in 1 litter betwixt the months of May and June.
The Arctic wolf hunts and eats mammals that vary widely in size. Much of their diet consists of Arctic hares, seals, lemmings, caribou, and sometimes they may even take downwards a moose.
ii. Polar Bear (Ursus maritimus)
One of the most famous tundra animals is the Polar Bear. They inhabit the Arctic tundra in Alaska, Canada, Russia, and Greenland.
Polar bears accept numerous adaptations that help them stay warm and camouflage in their snow-white environments. Their fur is white and hollow, which helps reflect sunlight, just underneath they take black pare.
Below their peel, they accept a layer of fat that helps maintain their trunk oestrus. Their paws are wide and apartment to help with walking on the snow and their toes have webbing which makes them an effective swimmer.
Polar bears hunt for seals that are nigh the surface of waters and wait for seal dens to find seal pups for food. Unlike other bears, polar bears do not hibernate and females will only use dens when giving nativity to proceed the cubs warm.
Co-ordinate to the International Union for Conservation of Nature (IUCN) Their conservation status is vulnerable as of 2015. Their habitat is threatened past melting ocean ice due to climate change on top of human activity such as oil and gas drilling.
iii. Chill Ground Squirrel (Spermophilus parryii)
Unlike their other squirrel family members constitute frolicking amongst forests, the Arctic Ground Squirrel inhabits the tall and Chill tundra biomes and resides in burrows. They are found in Alaska, Canada, Siberia, and northern British Columbia.
Arctic footing squirrels dig burrows a few feet cloak-and-dagger where they hide out in the winter months with their stored food from summer foraging. A colony tin consist of hundreds of these critters.
They are herbivores and mainly feed on grasses, mushrooms, willow leaves, seeds, and berries constitute past meadows, lakeshores, and river and sandbank.
4. Leopard Seal (Hydrurga leptonyx)
The Leopard Seal lives in the Antarctic tundra. These seal species inhabit the pack-ice that is formed past freezing seawater and may also be found on sub-Antarctic islands. Their layer of fat, called blab, helps them withstand the ice-common cold Antarctic body of water temperatures.
Leopard seals have slender bodies and long, sharp teeth that assist them consume fish, penguins, squid, and crustaceans. They chase by diving into the water to catch their prey. They are an apex predator of the Antarctic.
Female person leopard seals become through a ix-calendar month gestation menstruum and more often than not requite birth in Nov. Their conservation status is of least business organization and their only known predator is the killer whale.
5. Himalayan Tahr (Hemitragus jemlahicus)
Every bit their name states, the Himalayan Tahr is native to the high mountain tops of the Himalayas in Northern Republic of india to Bhutan. This makes the Himalayan Tahr a animal of the tall tundra biome.
Their winter coat consists of darker brown to red-brownish colors with a lighter underside and when temperatures rising in the summertime they form a shorter glaze that is light brown.
Infant Himalayan tahrs, chosen kids, are born between mid-April and mid-July following the breeding season, which occurs betwixt October and January. Kids are able to walk in but 3 hours from nativity.
Himalayan tahrs are herbivores and feed on various herbs and shrubs of the alpine country. They can alive up to 14 years in the wild. Their main predator is the snowfall leopard. Himalayan tahrs are about threatened on the International Union for Conservation of Nature (IUCN) Red List due to urbanization, tourism, and hunting.
6. Canada Lynx (Lynx canadensis)
The Canada Lynx is a threatened species that live in the Chill tundra. They tin can be spotted in Alaska, Canada, and northern U.S. states.
The fur that surrounds their ears helps go on them warm in cold, chill temperatures and fur located nether their paws allows them to walk in the snow without freezing.
Canada lynx have excellent night vision and are able to spot and hunt prey in the dark. Their diet consists mainly of the Snowshoe Hare, merely if availability is scarce they plow to eating smaller mammals and grouse.
Their conservation status is currently of least business concern co-ordinate to the IUCN Crimson List, but their population is threatened by urbanization, hunting and trapping, and logging.
7. Snow Leopard (Panthera uncia)
Snowfall leopards inhabit the loftier altitude terrain of the Himalayas, Siberian Mountains, and the Tibetan Plateau. They accept a beautiful dark-spotted coat that is light tan to cream in color with long bushy tails that help keep them warm.
Their diet largely consists of other mammals, such equally sheep, pikas, hares, and birds. Due to the rising temperatures from climate change, other predators that feed on the same casualty are increasing contest amongst nutrient sources.
The snow leopard is listed as a vulnerable species every bit of 2016 and their population is decreasing due to mining, tourism, urbanization, poaching, and climate change.
viii. Beluga Whale (Delphinapterus leucas)
Ane of the sea creatures that travels throughout the Arctic is the Beluga Whale. They take a distinct expect with their bulbous forehead and round white bodies. They are known as the "canary of the sea" every bit they make diverse sounds by clicking, chirping, and whistling.
Beluga whales feed on various bounding main life including salmon, shrimp, and mollusks. These whale species inhabit the Arctic sea until winter approaches and ice begins to form, causing them to migrate south in large groups called pods.
9. Caribou (Rangifer tarandus)
Known equally Caribou in Northward America and reindeer in Asia and northern Europe, these creatures live in the tundra and taiga biome. They are nomadic and travel long distances in herds.
They have footpads that change with the seasons to accommodate for the soft, boggy grounds of tundra summers. The pads harden to help them trek through the snow and water ice during wintertime.
Caribou are herbivores and feed mainly on grasses, willows, mushrooms, sedges, and lichens.
10. Lemming (Lemmus lemmus)
Lemmings are tiny rodents of the Arctic tundra. Various subspecies inhabit other biomes such equally temperate forests, merely the Kingdom of norway Lemming, Lemmus lemmus, resides in the tundra and tall region of Fennoscandia. This region includes Finland, the Scandinavian Peninsula, and a portion of Russian federation.
Although modest in nature, they accept a mighty impact on their ecosystem. Lemmings are at the lower terminate of the food chain and give predators, such as Arctic foxes, snowy owls, and Chill wolves, a source of nutrient year-round since Lemmings practice not hibernate.
Their fur colour changes with the seasons to assistance them hibernate from predators. In the summer, their fur is brown and in the winter it turns white. Lemmings live off of various seeds, plants, and berries throughout the year and tend to hide out in tunnels to go on warm once the common cold season arrives.
xi. Arctic Hare (Lepus arcticus)
Chill hares live in the Arctic tundra of northern Canada and can also be institute on islands about the declension of Greenland. These speedy hares use their potent dorsum legs to propel them up to 30 mph (48.2 kph) which helps them make great escapes from predators.
They accept several adaptations to defend themselves from predators and conquer tundra conditions. Their front teeth differ from other hares as they are longer and not as curved then they can uproot plants in tight rock crevices.
Their wintertime coat is white with black coloration on the tips of their ears and during the summer their glaze turns grayish-brown. Chill hares also have long claws that help them dig in snow.
The Chill Hare diet consists of berries, sedges, willow roots and twigs, and mosses.
12. Walrus (Odobenus rosmarus)
The Walrus has two subspecies, the Atlantic Walrus (Odobenus rosmarus rosmarus) and the Pacific Walrus (Odobenus rosmarus divergens). Both subspecies inhabit the Arctic and sub-Arctic tundra across the Northern Hemisphere. They lounge on sea ice and stick close to the coast.
They apply their long tusks for many things including helping themselves upwardly onto bounding main ice and opening breathing holes in the ice. Walruses take a lot of blubber to continue them warm when diving into frigid ice waters.
Their conservation status is vulnerable. Warming temperatures due to climatic change is threatening their sea ice habitats.
xiii. Arctic Play a trick on (Vulpes lagopus)
Terminal on the list for mammals in the tundra is the stealthy Chill Fox. They live in the Chill tundra all across the Northern Hemisphere stretching from Alaska and Canada to the coasts of Greenland and Russia.
Chill foxes mainly inhabit the grasslands of the Arctic tundra and feed on rodents, fish, birds, and sometimes vegetation if preferred nutrient is deficient. They are also scavengers and will eat leftover meals from other predators.
They have a white fur coat with gray coloration to blend in with their icy environs. They go through a molting procedure and shed their thick wintertime coat for the summer. Infant Arctic foxes are born with dark brown fur that lightens every bit they become older.

Birds in the Tundra
14. Emperor Penguin (Aptenodytes forsteri)
The elegant Emperor Penguin inhabits the Antarctic tundra. They are near threatened and their and their population is declining due to climate modify melting the ocean ice they travel on.
Emperor penguins are the tallest living penguin species and tin can stand at almost iv ft (1.2 m) tall. They have big white breasts, golden yellowish coloration on the sides of their caput, and a blackness face, flippers, and back.
Unlike other birds, emperor penguins accept special feathers that provide insulation. They also limit their activity in the winter and store body fat to keep them warm. These penguins stick together in colonies and huddle together to keep warm, specially males when incubating eggs during the winter.
15. Snowfall Petrel (Pagodroma nivea)
Snow petrels live in Antarctica and travel amidst the sub-Antarctic islands. They mainly reside close to the bounding main along cliffs where they build pebble-lined nests. Females lay simply ane egg at a fourth dimension and tend to the baby chick for most ii months until it leaves the nest.
Much of their diet consists of sea life such every bit fish, pocket-sized squid, mollusks, euphausiids, and sometimes leftover carcasses of seals and penguins.
xvi. Snowy Owl (Bubo scandiaca)
Next on the list is the Snowy Owl of the Arctic tundra. Although they plough all white with age, snowy owls are born dark grayish-brown and form a speckled-gray or brown and white coloration later on.
Snowy owls used to be of least concern, but due to their declining population threatened by human action, they are now vulnerable as of 2021.
Similar other owl species, these birds have peachy eyesight and look until they spot their prey earlier they snatch it with their talons. Snowy owls' favorite snack is the Lemming, but they too eat rabbits, fish, and other birds and rodents.
Snowy owls can brave the tundra year-round, but may migrate to marshes and fields in other regions.
17. Skua (Stercorarius parasiticus)
Skuas, also called Arctic Jaegers, are highly ambitious and predatory seabirds that live in the Arctic tundra of the Northern Hemisphere. They tin also exist found in the Southern Hemisphere where they drift for the winter.
Other birds autumn victim to skuas as they are kleptoparasitic, meaning they like to steal food out of the beaks and talons of birds conveying food back to their nests. They do so past attacking birds in flight until the nutrient is dropped.
Arctic jaegers hardly ever visit country except for breeding and spend virtually of their life out at sea.

Insects in the Tundra
18. Arctic Bumblebee (Bombus polaris)
Bumblebees are found all beyond the globe, even in the tundra. The Arctic Bumblebee, or Polar Bumblebee, inhabits the Arctic tundra of North America.
Arctic bumblebees are able to keep warm by shivering to generate heat. They also manage to brave the cold past having thick fur and use flowers to bask in the sunlight on warmer days.
As soon as spring comes in May, the queen bees begin buzzing around for nectar from freshly bloomed flowers. Worker bees don't announced until a month later. Chill bumblebees rely on various berries, flowers, and shrubs for food including bog blueberries, Arctic willows, Arctic poppies, and alpine bearberries.
19. Arctic Woollybear Moth (Gynaephora groenlandica)
A relative to the Woollybear caterpillar usually spotted in the United States, the Arctic Woollybear Moth lives within the Arctic Circle in Canada and Greenland.
These types of bees love to snack on the Arctic Willow, but spend much of their lives in a frozen state during the long winter season. Much similar some frogs that live in cold northern regions, they produce an antifreeze from sugars that allow them to freeze and thaw once temperatures rising.
One time they live out their life equally a caterpillar, they wrap themselves in a cocoon and form into a gray moth past springtime. A large portion of their life is spent as a caterpillar because in one case they transform into a moth, they lack a oral cavity and their sole purpose is to reproduce before they dice.
twenty. Arctic Musquito (Aedes nigripes)
Even pesky mosquitoes tin be constitute in the tundra. Although they may be irritating to humans, mosquitos play an important role in the food concatenation for tundra birds.
Every bit the tundra warms up in the summer months, wetlands form and attract Arctic mosquitos. They feed on the arable organic affair that forms in the bog-like atmospheric condition.
These insects are a great source of food for birds and other larger insects.

How Climatic change is Affecting the Tundra
The habitats of many tundra species are negatively affected past climate change. Some species may struggle to find food sources due to increased competition. Sea ice has been melting apace at 13% per decade. Species that depend on sea ice as their habitat are significantly afflicted by this.
Another hefty event of climate change is that ascent temperatures melt the superlative layers of permafrost. Melting permafrost allows for plant matter to decompose and as a result, releases greenhouse gasses into the atmosphere. Beforehand, permafrost helped to trap greenhouse gasses since plant material could not decompose in the frozen soil.
