The main predators of the tundra are the polar bear, the Arctic wolf, and the Arctic fox. They all have thick white coats that help them blend into their environment and stalk prey. [ 5 ] The polar bear spends the majority of its time out on the ice hunting seals and sometimes when small rodents are scarce on land the Arctic fox will follow the ...
In physical geography, tundra (/ ˈ t ʌ n d r ə, ˈ t ʊ n-/) is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: Arctic tundra, [2] alpine tundra, [2] and Antarctic tundra. [3] Tundra vegetation is composed of dwarf shrubs, sedges, grasses ...

The Arctic is rapidly changing from the climate crisis, with no "new normal," scientists warn.. Wildfires and permafrost thaw are making the tundra emit more carbon than it absorbs. From beaver ...
With wildfires and increased warming, scientists say the Arctic’s tundra is now a carbon source. The region had been a carbon sink for thousands of years (NOAA Climate.gov; Arctic Report)
The Canadian Arctic tundra is a biogeographic designation for Northern Canada's terrain generally lying north of the tree line or boreal forest, [2] [3] [4] that corresponds with the Scandinavian Alpine tundra to the east and the Siberian Arctic tundra to the west inside the circumpolar tundra belt of the Northern Hemisphere.
This was the Arctic’s second-hottest year on record, according to a new NOAA report. The tundra has become a source of emissions, rather than a carbon sink, the authors said. The Arctic is ...
The ecoregion has very little human habitation, and most of the non-ice terrain is moss and lichen cover. The region supports viable populations of arctic mammals such as muskox, arctic wolves, arctic foxes, arctic hares, polar bears, and caribou. [2] [4] [5] [6]
