Polar bears, foxes, and owls use insulated fur and feathers to protect from the cold conditions. [2] These complex interactions between plants, animals and abiotic factors in the tundra are held together by the permafrost layer, located 450 metres (1,480 ft) under the soil. [3]
Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66° 33’N). [1] This region is characterized by two biomes: taiga (or boreal forest) and tundra. [2]

In locations where dead vegetation and peat have accumulated, there is a risk of wildfire, such as the 1,039 km 2 (401 sq mi) of tundra which burned in 2007 on the north slope of the Brooks Range in Alaska. [14] Such events may both result from and contribute to global warming. [15]
Abiotic and biotic factors may work together in determining the range of a species. An example might be some obligate seeder plants where the distribution is limited by the presence of wildfires, which are needed to allow their seed bank to germinate, and also use dispersal of their seeds mediated by ants.
"At this time, it looks like there will be at least three major blasts of Arctic air that will affect the Southern states," AccuWeather Meteorologist Alex DaSilva said.
Humans can make or change abiotic factors in a species' environment. For instance, fertilizers can affect a snail's habitat, or the greenhouse gases which humans utilize can change marine pH levels. Abiotic components include physical conditions and non-living resources that affect living organisms in terms of growth, maintenance, and ...
An old castaway hut on the Antipodes Islands.. The islands constituting this ecoregion share a long history of isolation, both from other landmasses and each other. The isolation, combined with harsh climates characterised by low temperatures, strong westerly winds and few hours of sunlight in winter, have resulted in the evolution of many endemic plants and animals, though species richness is ...
