The Arctic fox is a small mammal (not much bigger than a house cat!) that lives in Arctic regions of the Northern Hemisphere, including Canada. Arctic foxes are hunters and scavengers that eat lemmings, voles, fish, bird eggs, and even berries and seaweed. The Arctic fox is not endangered, but it (along with other northern animals) is currently facing a major problem: habitat shifts due to climate change.
Years ago, the Arctic fox was the only fox around for miles, so it could live and eat without much competition. Unlike humans, animals can’t just put on or take off a jacket when the weather changes, and they certainly can’t move their family across the country to avoid nasty neighbours. Habitat conservation is especially important for species that live in environments that are changing. We know that Arctic foxes need to live in the cold, away from strong competitors, and have access to multiple food sources. Earth Rangers is a non-profit organization that works to inspire and educate children about the environment.
Earth Rangers is a registered Canadian charity (#892200528RR0001) whose mission is to educate kids about the importance of biodiversity and empower them to protect animals and their habitat.

Two men lean into a blizzard to chop ice for drinking water, an essential daily chore during a three-year Australian-sponsored scientific expedition to Antarctica from 1911 to 1914. Bred for strength and endurance, with thick fur to prevent frostbite, Greenland huskies pull a sledge on the ice early in the Australasian Antarctic Expedition.
In 1961, to commemorate the 50th anniversary of the expedition, a 5d stamp was issued showing Mawson in his balaclava.
His face nearly covered by frost, Cecil Thomas Madigan, the expedition’s meteorologist, seeks shelter indoors.
Born during the expedition, the beloved Blizzard, like all but two of the dogs, eventually had to be killed when they were no longer strong enough to pull sleds. Archibald Hoadley, Sydney Jones, and George Dovers were one of eight three-man teams sent out in different directions to map terra incognita. An icy tunnel was the only way into the Grottoes, a hut that was snowed over within days of being built. At Main Base some 1,500 miles away, 18 men made maps, ran experiments, and cooked in a 24-by-24-foot living area. In summer, a crew pitches a tent during a gale—a task that could take more than an hour in the incessant winds. A team member explores a massive ice cave less than a mile from Main Base hut, on the easternmost edge of Cape Denison.

Anchored off Cape Denison, the supply ship Aurora was the expedition’s only lifeline home. A few years after his scientific expedition and ill-fated journey, Sir Douglas Mawson revisits artifacts on display in Adelaide.
Although their gear was state-of-the-art, some team members modified clothing like this balaclava to make it warmer.
Mawson tossed his crampons to save weight, then had to improvise a makeshift pair when faced with steep, solid ice. Go behind-the-scenes with our storytellers and join conversations about photography, art, and journalism. Arctic foxes in Svalbard can find lots of food after an icy winter, but their populations drop a year after extreme weather events, researchers report in Science magazine.
These findings may be a bellwether of the radical changes in ecosystem stability that could result from anticipated future increases in extreme events due, the scientists warn.
The big ups-and-downs in the community’s population numbers were mainly controlled by rain-on-snow events, the researchers found. Hansen BB and Aanes R (2012) Kelp and seaweed feeding by high-arctic wild reindeer under extreme winter conditions. NTNU is the second largest of the eight universities in Norway, and has the main national responsibility for higher education in engineering and technology. Welcome to Science and Cocktails, a project that seeks to combine science with entertainment, after-work drinks, and music. These tents can survive very strong winds, one having survived at Ardery Island over the entire 1998 winter season. In certain regions, Arctic foxes will follow Polar bears out on the sea ice during the winter to scavenge on their leftover meals. However, because the temperatures in the north are changing, species that prefer warmer places are now moving north into the Arctic fox’s habitat.
Red foxes will outhunt them and take over their dens, leaving the Arctic fox without food or a home.
That’s why scientists are trying to figure out which habitats are important for these animals so we can all help protect them.
They look into why animals pick certain spots as the best place in their environment to live, such as places with lots of food to eat or shelter from harsh weather.
Animals can have a tough time adapting to changes that happen very fast, and right now the Arctic is changing rapidly!
One group of scientists that looked at European Arctic foxes predicted that their habitat could decrease by up to 56% by the year 2080 because of increasing temperatures, increases in the number of predators (Red fox!) and reduced food. Such ice masks could form in as little as an hour out in the extreme conditions of Antarctica, where winds could reach 200 miles an hour and winter temperatures were typically -20°F or colder.
Douglas Mawson’s team traversed many crevasses before one swallowed colleague Belgrave Ninnis, six dogs, and vital gear, including their tent and most of their food. Only two men on the expedition had been to Antarctica before, and some had never before seen snow. To unwind, they played records, gambled for chocolate, and listened to Mawson read aloud his favorite books.

Besides the bitter cold and strict food allotments, there was the ever present fear of getting lost. Trekking on the coastal ice shelf or polar plateau could be painfully slow, given the crevasses, ice blocks, and sastrugi—ridges of hard, windblown snow. They also provided dubious amusement: The crew would sneak up on penguins standing near cliffs and knock them into the ocean. As Mawson raced to meet it at the tail end of his punishing solo slog to the Main Base, he spied the ship departing for Australia. Scientists found that extreme icing caused widespread die-offs in one arctic animal community.
Rain-on-snow is an extreme situation that locks the deep-frozen arctic tundra under a sheet of ice.The ice keeps reindeer from grazing on their winter pastures and also deeply reduces the ability of the rock ptarmigan and sibling vole to find food.

Hypothermia (meaning lowering of body temperature below the normal) is the most dangerous risk.
We’re lucky to have her stop by the Wild Wire to introduce us to one of these adorable Arctic animals.Alysa McCallWhat animal lives in the Arctic, has four legs, thick white fur, travels across the sea ice to find food, and is being affected by climate change?
Its muzzle, legs and ears are short to prevent heat loss, and it has a thick layer of body fat and very thick fur to keep warm.
Conserving a habitat that has all the important things that an animal needs will make it easier for them to find food, be safe, mate and be healthier overall.
We need to save habitats that Arctic animals depend on most before the environment changes too much, which is why studying the habitat needs of northern animals is so important. If we want Arctic fox populations to exist forever, we will have to make sure we conserve suitable habitats for both Arctic and Red foxes.
This is why it is so important to keep warm and dry—taking the correct clothes and equipment with you is essential. You’d be right if you guessed Polar bear, but the animal I’m thinking about is the Arctic fox! Also, their fur is brown in the summer but turns white in the winter to help them blend in with their environment! Even though the simultaneous die-offs decreased the number of live prey available for foxes to eat, the high number of reindeer carcasses meant there was lots of food for foxes during the icy winter and the subsequent spring and summer. Maybe a big backyard, a soccer field at your school, food in your fridge, a warm place to sleep at night, or even nature trails to go hiking? The result is a deep reduction in the arctic fox numbers one year after the grazers die off.A Svalbard reindeer and ptarmigan an sharing ice-free spot, their only option for finding food.
