Features of the Tundra
|
Description
The Tundra is located in the polar regions of the arctic (60 degrees North and higher). Only animals and vegetation that have adapted to the extreme climates of the Tundra can survive in these regions. For example, since the polar bear has a fur coat and insulation, it is able to survive in these temperatures. There are not many species of animals or vegetation that can flourish in the Tundra because they will never be able to adapt, develop, and survive. Most biomes are not located near the Tundra because surrounding areas have similar climates and features. Primary succession: when a new habitat is created from an environment that was devoid of soil. Example: melting glaciers becoming a habitat without having soil Secondary succession: when a new habitat is created from an environment that previously had soil and vegetation Examples: fires, natural disasters, eruption, erosion Competition Exclusion Principle: two species that are competing for the same resources cannot coexist. Examples: Nutrients and sunlight are always at a low level, increasing competition and killing off species, e.g. seals Resource partitioning: sharing resources between species that coexist, leading to competition. Examples: Arctic geese and brown bears Effects on Tundra: Latitude, Time, Habitat, Size, Distance |
