Tundra Animal Pictures Biography
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. Approximately 20% or of the surface of the Earth falls into this category.
You will find the tundra biome along the coastal regions of the arctic. The combination of polar air and arctic air masses dominate in this particular biome. There is a very long winter and it is cold and harsh. The summer is short and mild, but most experts don’t view it as a true summer season.
The tundra biome consists of wasteland that is extremely cold. There are lots of rocks too but not very much vegetation. There are almost no trees at all found in this particular biome. The area is very cold and often dry. Yet the temperatures don’t warm up enough for the snow that is in place to melt completely. Muddy areas can develop when it does warm up though as some of the ice begins to melt.
Greenland is the number one place that people think of when they consider a tundra biome. They also think about areas of Alaska. However, there are also areas of Northern Canada and Northern Russia that are a tundra biome. The span of the tundra biome is mainly in areas where most people have never been. They would find such living conditions to be too harsh for them to thrive there.
The temperatures are very low in the tundra biome. In the winter time they can be as low as -50 degrees. In the summer it is rarely about 40 degrees. It is usually very dark in the winter months. Even the summer doesn’t offer much sunlight as it is often cloudy during those 6 to 8 weeks. There isn’t much rainfall in such areas, less than 30 inches annually. The majority of the moisture though comes from the ice and the snow pack. Approximately ¾ of the tundra biome is permafrost.
Due to the balance of animals and plants not being equal in the tundra biome, it is one of the few places on Earth known as a carbon dioxide sink. This means more carbon dioxide is taken in than in released back out. It is believed that this has contributed to the growing global warming concerns for the tundra biome.
If such global warming continues, the temperatures will be higher than they have ever been in this biome. As a result, layers of permafrost can completely melt. That would completely transform the overall structure and balance among plants and animals that live in the tundra biome.
You would think that this biome would be one free of people, but it isn’t. In fact, many people continue to move to them in order to get work on oil rigs and in the mines. As a result this has caused some additional stress for both plants and animals that live in this natural environment. The efforts of humans have brought with them additional problems. For example where they place roads can be destroying the natural habitat of living elements.
Another example is that there are huge masses of insects that live in the tundra biome. Humans have used large amounts of pesticides to help reduce problems they have had with them. However, birds that are migrating depend on those insects as a source of food. They have found there is less and less each year when they pass through.
