  • Taiga is the Russian word for forest and is the largest biome in the world.

      This is an interesting fact...
  • The taiga is also known as the boreal forest. Did you know that Boreal was the Greek goddess of the North Wind?

      I have heard of the Aurora Borealis -- I wonder if this is related to the same Greek goddess?
  •  
    A lot of information on Taiga Ajay

    Wow!That is really cool! One question: What does the North Wind mean?

The Boreal Forest Biome: Taiga Biome - 0 views

  • Introduction. The boreal forest (also known as the taiga, a russian word meaning swampy moist forest) is found in a nearly continuous belt across North America and Eurasia. Most of Canada and Russia are covered by coniferous trees that make up this biome. This biome is defined mainly by the trees that compose it. The climax trees are furs, spruces and pines. Subclimax plant communities may have deciduous trees like larch, tamarack and birch. Much of the zone that this biome covers was formerly glaciated. Today large sections have permenent permafrost.

      Good intro. I didn't know Taiga was actually called the boreal forest!

Tiger - Wikipedia, the free encyclopedia - 0 views

  • Highly adaptable, tigers range from the Siberian taiga, to open grasslands, to tropical mangrove swamps. They are territorial and generally solitary animals, often requiring large contiguous areas of habitat that support their prey demands. This, coupled with the fact that they are endemic to some of the more densely populated places on earth, has caused significant conflicts with humans. Of the nine subspecies of modern tiger, three are extinct and the remaining six are classified as endangered, some critically so. The primary direct causes are habitat destruction and fragmentation, and hunting. Their historical range, which once reached from Mesopotamia and the Caucasus through most of South and East Asia, has been radically reduced. While all surviving species are under formal protection, poaching, habitat destruction and inbreeding depression continue to be threats.
  • Tigers are perhaps the most recognisable of all the cats (with the possible exception of the lion). They typically have rusty-reddish to brown-rusty coats, a whitish medial and ventral area, a white "fringe" that surrounds the face, and stripes that vary from brown or gray to pure black.
  • Main article: Golden tabby A rare golden tabby/strawberry tiger at the Buffalo Zoo. In addition, another recessive gene may create a very unusual "golden tabby" colour variation, sometimes known as "strawberry." Golden tabby tigers have light gold fur, pale legs and faint orange stripes. Their fur tends to be much thicker than normal.[50] There are extremely few golden tabby tigers in captivity, around 30 in all. Like white tigers, strawberry tigers are invariably at least part Bengal. Some golden tabby tigers, called heterozygous tigers, carry the white tiger gene, and when two such tigers are mated, can produce some stripeless white offspring. Both white and golden tabby tigers tend to be larger than average Bengal tigers.

Taiga Biome - 0 views

  • The taiga or coniferous forest is probably the world's largest land biome. It is located south of the tundra and stretches across portions of North America. Europe and Asia. During the summers, the soil remains very wet and is suitable for lichens and mosses. Fir and spruce trees grow well in this environment. The trees provide homes for many birds including the crossbill, which is capable of cracking cones to eat the seeds. A variety of animals are found in the taiga. They include moose, weasels. wolves, deer. Lynx, caribou, porcupines, beaver, mink and bears.

  • A biome is an area on the earth's surface that has a certain set of characteristics. There are seven kinds of biomes in the world: tundra, taiga, temperate forest, tropical rainforest, desert, grassland, and ocean. The map above shows where each of these biomes can be found around the world. Although it does not appear in the key, the ocean is represented by the blue area on the map.

Alpine Biome - 0 views

  • Cold, snowy, windy. When you hear those words they make you think of mountains. The Alpine biome is like winter is to people in New England; snow, high winds, ice, all the typical winter things. In Latin the word for 'high mountain' is 'alpes'. That is where today's word alpine comes from. Alpine biomes are found in the mountain regions all around the world. They are usually at an altitude of about 10,000 feet or more. The Alpine biome lies just below the snow line of a mountain. As you go up a mountain, you will travel through many biomes. In the North American Rocky Mountains you begin in a desert biome. As you climb you go through a deciduous forest biome, grassland biome, steppe biome, and taiga biome before you reach the cold Alpine biome. In the summer average temperatures range from 10 to 15° C . In the winter the temperatures are below freezing. The winter season can last from October to May. The summer season may last from June to September. The temperatures in the Alpine biome can also change from warm to freezing in one day. Because the severe climate of the Alpine biome, plants and animals have developed adaptations to those conditions. There are only about 200 species of Alpine plants. At high altitudes there is very little CO2, which plants need to carry on photosynthesis. Because of the cold and wind, most plants are small perennial groundcover plants which grow and reproduce slowly. They protect themselves from the cold and wind by hugging the ground. Taller plants or trees would soon get blown over and freeze. When plants die they don't decompose very quickly because of the cold. This makes for poor soil conditions. Most Alpine plants can grow in sandy and rocky soil. Plants have also adapted to the dry conditions of the Alpine biome. Plant books and catalogs warn you about over watering Alpine plants. Alpine animals have to deal with two types of problems: the cold and too much high UV wavelengths. This is because there is less atmosphere to filter UV rays from the sun. There are only warm blooded animals in the Alpine biome, although there are insects. Alpine animals adapt to the cold by hibernating, migrating to lower, warmer areas, or insulating their bodies with layers of fat. Animals will also tend to have shorter legs, tails, and ears, in order to reduce heat loss. Alpine animals also have larger lungs, more blood cells and hemoglobin because of the increase of pressure and lack of oxygen at higher altitudes. This is also true for people who have lived on mountains for a long time, like the Indians of the Andes Mountains in South America and the Sherpas of the Himalayas in Asia. bibliography: "Himalayas", http://encarta.msn.com/find/, (June 2000).
