Tundra Tundra is the world's youngest biome. It was formed 10 000 years ago. Located at latitudes 55° to 70° North. Almost all tundras are located in the Northern Hemisphere, encircling arctic desert and extending south to the coniferous forests of the taiga. The ecotone (ecological boundary region) between the tundra and the forest is known as the tree line or timberline. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-moulded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created by precipitation. The most distinctive characteristic of tundra soil is its permafrost, a permanently frozen layer of ground. The average winter temperature is -28°C, but the average summe...
1. Key features for all studied biomes. Tundra The main seasons are winter and summer. The tundra is the world's coldest and driest biomes. The average annual temperature is -28° C. Nights can last for weeks when the sun barely rises during some months in the winter, and the temperature can drop to -70° C. During the summer the sun shines almost 24 hours a day. Summer are usually warm. Average summer temperatures range from 3° to 16°C. TaigaTaiga is the Russian word for forest and is the largest biome in the world. It stretches over Eurasia and North America. The taiga is located near the top of the world, just below the tundra biome. The winters in the taiga are very cold with only snowfall. The summers are warm, rainy, and humid. Some of the animals in the taiga hibernate in the winter, some fly south if they can, while some just cooperate with the environment. GrasslandsGrassland biomes can be found in the middle latitudes. They can...

Tundra animals Reindeer Reindeer were first domesticated in Norway and northern Asia. When it was seen how valuable they were, they were brought to Alaska in 1887 and later to parts of Canada. These North American reindeer became known as caribou. Although they are called by different names, they are both considered to be a single species. Unlike deer, both the male and female have antlers. The antlers of the male are long, branched and massive, and they are a little flattened at the ends. The antlers of the female are much shorter, simpler and more slender and irregular. Their large, spreading hooves support the animal in snow in the winter and marshy tundra in the summer. Reindeer are also great swimmers and use their feet as paddles. They can also lower their metabolic rate and go into a semi-hibernation when conditions get very harsh. When it looks like there is nothing to eat on the win...

Early History The first inhabitants of Canada were native Indian people who were called as Inuits. They are believed to be in Canada since about 10000 BC. The Inuits came to Canada from Asia crossing the Bering land bridge. The earliest discoveries in Canada were made by the Vikings. In AD 985 Vikings sailing from Iceland to Greenland were blown westward off their course and the Vikings sighted the coast of Labrador peninsula. The report of forested areas encouraged further exploration because the colonies in Greenland which belonged to the Vikings lacked lumber. In AD 1000 Leif Ericson became the first European to land in North America. The first colony was established what was described as Vinland by the Vikings. It was located on the northernmost tip of todays Newfoundland. There has also been a theory that the Vikings penetrated Hudson Bay and reached the Great Lakes region but recent investigations have...
