The First Thanksgiving.

Christopher Jones was the captain of the Mayflower and sailed in 1620. The ship weighed 180 tons! They anchored off the tip of Cape Cod on November 11, 1620. There were 103 people on the Mayflower and nearly half of them died!

Alpine Biome

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.
So, the alpine biome is a very cold and harsh place to live.

Humans Impacts.

Humans have had a major impact on the Taiga. There are no positive impacts on the Taiga...don't pollute it. Negaitive impacts include, acid rains, global warming, and deforestations. I think they should stop. I think this because,there are no positive impacts, and a lot of negitive impacts.

Natural Events

Natural events inculdes weather and climate. The weather and climate of our environment is also varied because the biome is located in many countries. One country in the Taiga is Canada. The weather and climate affects living organisms, because there is floods, heavy rain, and avalanches, the people and animals have to take shelter or migrate.

Geographical Features.

The geographical features of our environment is diverse. On one of the continents in our environment, there are mountains, forests, and lakes, because of the very cold climate, there are not that many farms.

Maps

This latitude and longitude of my environment, Taiga is varied. The reasone it is varied is because it is stretched through Canada, Europe, and Russia. The political details inculdes the groverment. One country in our biome is Canada. Their goverment includes executive, legislative, and judicial branches. The population of our environment is also varied. One country located in our environment is Russia and their population is 142,008,838. Some of the natural resources of Taiga are nickel, aluminum, oil, gas, diamonds, coal, and wood. One event that occurred in the country of Europe was The Reformation.

Taiga Biome

Taiga is the Russian word for forest and is the largest biome in the world. It stretches over Europe, Asia and North America. The Taiga is located near the top of the world, just below the Tundra biome.
The main seasons in the Taiga are winter and summer. The spring and autumn are so short, you hardly know they exist. It is either hot and humid or very cold in the Taiga.
 The winters in the Taiga are very cold with only snowfall. The summers are warm, rainy, and humid. A lot of coniferous trees grow in the taiga.
   Taiga doesn't have many plants or animals, but it has lots of insects in the summertime. Bird migrate here to nest and feed. But mammals that do live here are the mainly seed-eating squirrel, deer, moose, elk, and snowshoe hare. The predators for this area are grizzly bears, wolves, lynxes, yeah pretty scary.
    Overall the Taiga is a very beautiful hot and humid place, but it can also be cold and dangerous. There are not a lot of species of plants in the Taiga because of the harsh conditions. Not many plants can survive the extreme cold of the Taiga winter. There are some liches and mosses, but most plants are coniferous trees like pine, white spruce, hemlock, and douglas fir.
