Betwixt the biotic and abiotic factors of the tundra A temperature ranging from 12 to -27 ° C and plants that are characterized past shallow roots stand out. The term tundra is used to ascertain a set of biotic areas characterized by the lack of trees, very low temperatures, a lot of air current and niggling rainfall.

The proper name seems to derive from several languages, such as Russian тундра and from the Finnish vox tunturia, which hateful "evidently without trees"; and the termtūndâr, from the Kildin Sami language of the Kola peninsula (Russia), which means "infertile state".

This biome is found in diverse regions of the planet, especially in the polar areas; these areas occupy near 20% of the planet's surface. In the northern hemisphere it is constitute in America in countries such as Canada (north), Denmark (Greenland) and the Us (Alaska).

In Europe information technology is along the entire Arctic declension, which includes Republic of finland, Republic of iceland, Norway and Sweden. In Asia information technology is located in the region of Siberia (eastern Russia) and in the southern hemisphere of America it extends into countries such as Argentina and Republic of chile.

Other locations in the tundra are the islands that surround the Antarctic Circle, such as Southward Georgia and Kerguelen.

Full general characteristics

The tundra has a large number of biotic and abiotic factors that narrate information technology. In addition to these, there are also some peculiarities that define this biome in a general way. Some of these characteristics are the following:

- They are areas with extremely low temperature climates.

- Biological diversity is relatively low.

- Soils take limited drainage.

- The morphology and architecture of the found community is simple.

- The reproductive seasons of the flora and creature are brief.

- Nutrients and free energy are available mainly in the course of decomposing or dead organic thing.

- There are winds in a higher place 20 km / h almost of the year, and can exceed 60 km / h.

Types of tundra

Arctic

Equally its name implies, it is located in the polar zone of the Arctic, in the northern hemisphere. It circles the due north pole and extends into the taiga.

The defining feature of this tundra is the underground layer of ice or frozen soil (permafrost) inches from the surface.

Antarctica

It is found in the southern hemisphere in Antarctica and on the subantarctic islands. This tundra is characterized past being an surface area generally covered with water ice, similar near of the Antarctic continent.

However, there are some areas that are non covered with ice merely with rocky soil, and it is in these that the tundra exists as such. Permafrost also occurs on this type of tundra on the subantarctic islands of S Georgia and the South Sandwich.

Alpine

Information technology occurs in mountainous areas around the world, specifically in mountains that exceed 3500 one thousand in height. This tundra is too devoid of shrubs and copse, and has ameliorate drainage than other tundras because in that location is no permafrost.

Abiotic factors

The term abiotic means that it has no life; therefore, abiotic factors are those without life. Inside this group are temperature, luminosity, salinity and nutrients, among many others. The abiotic factors that define the tundra are the following:

Altitude

The tundra tin be institute both a few meters above sea level and in some arctic, Antarctic and subantarctic islands.

For example, in the specific case of the alpine tundra, it is plant in mountain areas that exceed approximately 3,500 m in altitude.

Temperature

This biotic area is known for its low temperatures, although these can still rise or fall depending on the fourth dimension of yr.

Depression temperatures range from -34 to -27 ° C in the wintertime flavor and from iii to x ° C in summer. Even some arctic tundras written report 12 ° C in summertime.

Permafrost

It is the layer of the subsoil that is permanently frozen. The depth varies from place to identify, but ranges from approximately 25 to ninety cm in depth.

This layer is characteristic of the tundra and is present in about all the regions divers as tundra, except those of the alpine zones.

Calorie-free

In the tundras the availability of sunlight is quite limited throughout the year. Even in the summer (six to 8 weeks) the availability of low-cal is similar to a cloudy mean solar day.

This time of greatest amount of available light coincides with the reproductive flavour, which lasts between 50 and 60 days.

Rainfall

When information technology comes to rainfall, these areas are practically desert places. Atmospheric precipitation is very low and usually occurs in the grade of snow.

For example, in Arctic tundra rainfall tin be as high as 25 to 35 cm (including snowmelt).

Biotic factors

In contrast to abiotic factors, biotics are represented past the set of living beings in an area. Examples of biotic elements are bacteria, fungi, plants and animals.

In the tundra the biodiversity is lower compared to other biomes. Even some tundras are more various than others and this is due in part to abiotic factors that govern the different areas where they are constitute. Below we will detail the establish and animal biotic diversity co-ordinate to the blazon of tundra:

-Artic

Vegetable

The presence of permafrost limits the evolution of deep roots and, in turn, restricts the shape and structure of the plants that tin can thrive in this and all types of tundra that possess it.

At least 1,700 species of plants accept been described for the Chill tundra, among which at to the lowest degree 400 varieties of flowering plants, grasses, shrubs, some liverworts, mosses and even lichens stand out.

Brute

With regard to fauna, the Arctic tundra is depression in fauna biodiversity but with relatively large populations of each species.

Near 48 species of mammals take been reported, such as reindeer, oxen, wolves, polar bears, free arctic and arctic foxes, amongst others.

-Antarctica

Vegetable

A study carried out in 2004 indicated that the Antarctic flora is represented past more than than 1200 species of plant organisms, amidst which are more than 300 types of lichens, a hundred mosses and 700 species of rock, aquatic and soil algae. There are very few species of flowering plants and grasses.

Animal

In this region, whose surface is mainly covered with water ice, several species of mammals and birds have been described that alternating their life in the h2o and on the declension, such as the Weddel seal, the leopard seal and several species of penguins, such as the emperor. There are too small mammals introduced past homo, such every bit rabbits and cats.

-Tall

Vegetable

The alpine tundra presents a vegetation very like to that of the other types of tundras (chill and Antarctic). More than 300 species of plants are known to exist, including grasses, shrubs, hedges, and some species of mosses and lichens.

Animal

In this type of tundra, a diverse grouping of insect species from the Orthoptera (grasshoppers) and Coleoptera (beetles) groups, among others, has been described.

Mammal species such every bit marmots, goats, elk, and sheep accept also been documented. As for birds, the most diverse group belongs to the Tetraonidae family.
