Taiga Fun Facts. Tundra Characteristics. Rising global temperatures are forcing bears to spend more time on land and to go longer between meals. If no food is found some resort to cannibalism. The WWF is a non-governmental organization that is trying to save the Arctic and the organisms that live and thrive in it's ecosystems. They have been active in the Arctic for decades. Back in Controls were so successful that 10 years later the number of bears in Norway had doubled. At the same time they are protecting unique habitats and wildlife.

More than , sq km of the Arctic is now protected from threats such as mining and oil drilling. Today, climate change is the biggest threat facing the Arctic and its wildlife. They are researching how climate change is affecting Arctic ecosystems, and how they can help them adapt and survive. There was a problem submitting your report. Please contact Adobe Support.

The History In the Arctic and Arctic Tundra scientists have been studying the increase of polar bear deaths.

R-selected Species R-selected species : a species that produce many offspring i. K-selected Species K-selected species : a species that produces one to two offspring in their lifetime and live for many many years. Specialist Species Specialist Species: a species that require very specific diet or need a certain habitat to survive. Generalist Species Generalist Species: a species able to live in a wide variety of environments and can use a wide variety of different resources.

Arctic Fox Interspecific Competition They compete with other foxes for a mate Parasitism Hunts and eats lemming, benefiting the fox but not the lemming. Is eaten by polar bears and other large organisms victim of parasitism. Commensalism Follows polar bear and feeds on the remains of its kills but polar bear receives no benefit. Follows caribou because caribou loosen the soil which makes the hunting process easier for the arctic fox. Arctic Wolf Predation Arctic wolves hunt and feed on caribou; benefiting them while not benefiting the caribou. Mutualism After the pack is full the carcass left behind can be food for Arctic foxes; this is benefiting both species.

Resource Partitioning Wolf packs have separate territories which makes food for the packs divided; benefiting both packs by not fighting for resources. Population Human population The human population is said to be 4 million but do to harsh weather conditions it may be decreasing year by year. Geology In the center of the Arctic is a large basin covered by the Arctic Ocean. Primary Succession As Earth began to warm, glaciers began to melt and the land was lifeless and rocky.

Secondary Succession After Hurricanes and fires, soil remained and succession was possible. Saltwater System Do to large amounts of sea ice melting it is causing the sea level to rise and new currents to form. Ice Caps Moving The ice caps shrinking and shrinking every year. Freshwater Systems Due to sea ice caps melting, weather patterns have been changing and it's beginning to rain more.

That is turning the tundra into a source of greenhouse-gas emissions, as soil microbes convert carbon into carbon dioxide and methane. The tundra is also slow to repair itself from physical disturbances, such as tire tracks from heavy vehicles. Climate Change A warmer climate could radically change tundra landscapes and what species are able to live in them. Warming creates potential feedback loops that encourage further destabilization of tundra ecosystems.

The release of methane from deteriorating permafrost, for example, feeds the thawing cycle, while higher temperatures drive the growth of shrubs, which can change soil temperature and prevent snow from reflecting out heat. Thriving shrubs also crowd out lichen, an important food source for caribou and other animals. Warmer tundras could also see increased risk of wildfires and drought—scientists have documented a significant disappearance of lakes in western Greenland between and Air Pollution Air pollution affects tundra environments in different ways.

A recent study found that Arctic clouds are particularly sensitive to air pollution, which spurs cloud formation and has a blanketing effect. Black carbon from diesel engines, fires, and other combustion can settle on snow, decreasing its ability to reflect sunlight and causing faster melting. Chemicals used in coolants and aerosol sprays have driven ozone depletion at the North and South Poles, which can let in stronger ultraviolet light rays.

And toxic mercury, sent into the atmosphere by coal-burning and industrial activity, is accumulating in the Arctic tundra, threatening both humans and animals who live in the region. Air pollution can also harm or kill the important food source of lichen. Industrial Activity The oil, gas, and mining industries can disrupt fragile tundra habitats. Drilling wells can thaw permafrost, while heavy vehicles and pipeline construction can damage soil and prevent vegetation from returning. This activity also increases the risk of toxic spills. Seismic testing for oil and gas operations in the s left tracks on the tundra that are still visible decades later. Invasive and Migrating Species Climate change is driving down populations of some Arctic tundra natives, such as caribou also known as reindeer , by fostering an increase in parasites and disease while damaging food sources.

But other species, such as shrubs and the wolf spider Lycosidae spp. The red fox Vulpes vulpes , which is typically found farther south, is moving north onto the tundra and competing with the Arctic fox for food and territory. Though few invasive species have yet to take root in the Arctic, climate change increases the risk this could happen. And human activity, both near and far, can change the balance: As snow geese have learned to feed on farmlands rather than in the wild on their migration routes, their exploding numbers have threatened to degrade their tundra nesting sites. Solutions Cutting harmful, planet-warming pollution by switching away from fossil fuels is key to safeguarding Earth's tundra habitats.
