Tundra

By:Luke Lashley

Location

Tundras can be found near the north pole, Some examples are North Canada, Alaska, Russia, and some south Greenland.


Abiotic factors, Climate, and Rainfall

Some abiotic factors are strong winds,short summer days, only 6-10 inches of rainfall a year(including melted snow), short summers which are about 6-10 weeks long, and winters that last very long and go down to around -20 °F -30 °F and only up to 20 °F.


Plant Life

The tundra has a variety of different plant life. In order for these plants to survive they have to stay low and close to the ground to avoid strong winds. Most plants also have hairy stems to stay warm in the summer.

Animals

Animals in the tundra have to make a lot of changes to survive. They may add more body weight, change how they fly, or use their fur to their advantage.


An example of cooperation is when polar bears catch the food and arctic foxes follow behind and eat the polar bear's left overs.

An example of competition is when musk Ox's and caribou fight for sedge.

A few predator prey relationships are

  • Polar bears eating arctic foxes
  • Brown bears eating arctic hares
  • Arctic wolves eating musk ox
  • Arctic foxes eating lennings

Ecological concerns

While the tundra used to be untouched it is now in grave danger. Many animals in the tundra are now protected such as the snowy owl polar bears. Why? You may be asking. Humans are the cause of the majority of concerns in the tundra. Humans would hunt snowy owl and polar bears to the limit where they have become endangered. Because of machinery and global warming the tundra is being destroyed. We need the tundra to help control the temperature of Earth. Not only does it help with the temperature, but without the biome many species would become extinct including birds that migrate to the tundra, causing disorder in the entire food chain.
