Transcript of Tundra Biome
Henry Molina Ecology Specific Example Video Weather Plant Life ARCTIC TUNDRA Tundra Biome \(^.^)/ Image: Citation Page Solar Radiaton http://www.blueplanetbiomes.org/climate.htm Weather,Tundra Climate Air Circulation academic.regis.edu/ckleier/ENVS%20250/Ch_7_biomes.ppt Online Ppt Air Circulation. Latitude 60-75 degrees up North or South
The tundra is located on the top of the world! EARTH!
Its close to the North Pole, and its Cold Winter for months!
In the other hand during the summer the ice melts .
Its coldest can be -10 degrees F and cannot go higher that 45 - 50 degrees.Summer days are long as 24 hrs of sun,and cool (growing season) .The North Pole is tilted towards the Sun and It last for 60 days and the rest are long dark winters,receiving no type of Sunlight http://www.blueplanetbiomes.org/world_biomes.htm Tundra Map,colored region Image not
sunlight South North The air Circulation
changes direction when you see the North and the South.
North circulates Counterclockwise
While south circulates Counter clock wise like so Like the desert for example they both receive a small amount of rain (precipitation )receives less than 25 Cm
each year and most of it is snow.The only difference is their temperatures. Convention cell: Polar Cell Rain...? http://minerva.union.edu/failinge/earths_convection_cells.html Main Convention Cells Tundra comes from the Finnish word tunturi, meaning treeless plain.
Only 1,700 species of vegetation,(plants) not much those are:
shrubs, sedges, mosses, lichens and grasses.
400 kinds of flowers. They must adapt to the cold summers.
As you notice they are very close to the surface,
and they adapted to that because of harsh winds . The Tundra is a VERY windy place Moisture level is one of the most Important Factors in the Tundra. Moisture changes in curtain places:
Meadows-large amount of moisture
and the drier is dominated with small lichens,dwarf shrubs Cotton Grass Shrubs &
flowers.. Animal Life There isn't a lot of Biodiversity in the Tundra but there are 48 different kinds of species.
Hares,Snowshoe rabbits,Wolfs,shrews(they look like mice),foxes,bears,dear ,snowy white owl Harlequin Duck, rodents,insects... (Mosquitoes)
Huge herds : Caribou
Small herds such as Oxen, Polar bears ECT! What do they eat? The Caribou for instance eat
lichens and plants.
The Arctic foxes,polar bears,
they are the predictors of the tundra. http://www.blueplanetbiomes.org/tundra.htm Tundra. Arctic tundra occurs in the far Northern Hemisphere, north of the taiga belt. The word "tundra" usually refers only to the areas where the subsoil is permafrost, or permanently frozen soil. The soil there is frozen from 25–90 cm (10–35 in) down, and it is impossible for trees to grow. Instead, bare and sometimes rocky land can only support low growing plants such as moss Notable animals in the Arctic tundra include caribou (reindeer), musk ox, arctic hare, arctic fox, snowy owl, lemmings, and polar bears (only the extreme north) Some common adaptations of resident animals in the arctic and alpine tundra:
- short and stocky arms and legs.
- thick, insulating cover of feathers or fur.
- color changing feathers or fur: brown in summer, and white in winter.
- thick fat layer gained quickly during spring in order to have continual energy and warmth during winter months.
- many tundra animals have adapted especially to prevent their bodily fluids from freezing solid. Cool interesting facts!!! :D The tundra is known as the second most deadly environment in the world. The tundra biome is believed to be the youngest of all of them in the world. It was believed to have formed approximately 10,000 years ago Global warming is currently harming the Biome,the ice in the summers are melting too fast :/
