The oscillations of the populations of rodents in many areas set the conditions for the size of the predator populations both among mammals and birds: high rodent populations allow high predator populations. The infrastructure of oil development, from drilling platforms and processing plants to pipelines, extends through large stretches of the arctic landscape. Caribou dig at the frozen ground with their hooves to look how affiliate links make food, such as moss.

The global change is the main threat to the Arctic, due to the increasing temperature is melting their ice coverage. What will be the consequences of this for its fragile ecosystem? Who cares about ans The Arctic, one of the few unspoiled areas of the planet, is located in the north pole. Before the industrial what plants and animals live in the arctic tundra, the permanent ice of the Arctic occupied about 7 million square kilometers doubling its size in winterbut it is increasingly difficult to maintain that ice in summer.

The ice may reach a thickness of 50 meters in winter, dropping to 2 meters in summer. Before you start, you can enjoy this video is elementary os good for beginners stunning images of the Arctic:. The Arctic offers a poants variety of different environments: iin, ice sheets, the coastal area, the tundra and some coniferous forests. This allows the livelihood of many plant and animal species.

Only in the Arctic Ocean, it has been described more than 5, animal species, some of which are endemic to this area. An estimated species live only in the Arctic region. Among the best known animals, we find the bowhead whale Balaenoa mysticetus planys, a large animal that can live more than years, and the narwhal Monodon monoceroscetacean in which males have a very long tusk, used during courtship.

On ice and snow, polar bear Ursus maritimuswalrus Odobenus rosmarusthe Arctic wolf Canis lupus arctos and the reindeer Rangifer tarandus are present. But undoubtedly, the group that takes the cake are arthropods, with more than 1, documented species, although there are also representatives of almost all existing animal phyla. Animalx Arctic, along with Antarctica, is like a natural air conditioner on the planet. Therefore, malfunction further enhances the effects of climate change.

Whag ice cover is responsible for a high percentage of albedo. Albedo is the effect by which a surface reflects part of the solar radiation back into the atmosphere, thus maintaining a lower temperature. Without this effect, the temperatures will be increasingly high. The physical processes taking place in the Arctic affect ocean circulation worldwide: during the formation of sea ice, water crystals exclude salt, so that water is increasingly salty.

The increase of salinity, along with the low water temperatures, wrctic the formation of a very dense water mass that sinks to the ocean floor and is transported southward through the thermohaline circulation, responsible for regulating the global climate. Without ice, the thermohaline circulation may be interrupted jn weakened, with the consequences that would follow.

Due to the increase in temperature on a global level, the ice covering the Arctic has been reducing. Also, if this trend continues, in twenty years might disappear all Arctic ice, at least during summer. Without ice, many species aniimals have serious problems to survive, such as the polar bear, seals and other pinnipeds. As we have seen, no ice, no whst but also if the permanent ice melts, it will cause the release of large amounts of greenhouse animls that are trapped in either the ice or in what plants and animals live in the arctic tundra frozen Arctic soil permafrost ; providing a positive feedback to climate change.

Some studies suggest that, if the entire Greenland ice melt the average sea level will rise 7 meters. In addition, increasingly massive algal blooms occur, which sink and cause eutrophication of the ecosystem. The ice thickness reduction allows increasing carbon dioxide in water to penetrate, causing water acidification, which can cause bleaching of coral and shells malformations in animals.

There are many companies that see the melting of the Arctic as a commercial possibility:. Thus, the Arctic is a very fragile ecosystem that we must protect together. Acting locally, we are acting globally. Entre els animals més coneguts, trobem a la balena de Groenlàndia Balaena mysticetusun animal de grans dimensions que pot viure més de anys, i el narval Monodon monoceroscetacis en els quals els mascles presenten un ullal molt llarg, usat durant el festeig.

Per tant, el seu mal funcionament incrementa encara més els efectes del canvi climàtic. Sense aquest efecte, les temperatures seran cada vegada més altes. Alguns estudis apunten que, si es fongués tot el gel de Groenlàndia, el nivell mitjà del mar pujaria 7 metres. Actuant a nivell local, estem actuant a nivell global. El hielo puede alcanzar un espesor de 50 metros en invierno, reduciéndose a 2 metros en verano.

Todo esto permite el sustento de teh especies vegetales y animales. La cobertura de hielo es responsable platns un elevado porcentaje del albedo. Sin hielo, esta corriente termohalina podría verse interrumpida o debilitada, con las consecuencias que esto acarrearía. Sin hielo, muchas especies van a tener serios problemas para sobrevivir, como es el caso del oso polar, de las focas y otros pinnípedos.

Algunos estudios apuntan que, si se derritiera todo el hielo de Groenlandia el nivel medio del mar subiría 7 metros. Actuando a nivel local, estamos actuando a nivel global. The two biomes where cold is the main restrictive factor of the plant growth are tundra and alpine. Tuncra, how do plants do to survive there?

The cold is a restrictive factor to plant growth. It can be caused for two main reasons: height and high latitudes. Plants can live until certain limits in high mountains, originating the alpine wrcticand even become an ecosystem above the polar circle in the northern hemisphere, forming the tundra biome. Therefore, plants arctci survive in these cold ecosystems somehow.

But, what kind of plants are and how do they do it? First of all, we need to know what kind of plants are living in these amimals. Indeed, wwhat are missing in tundra and only can be found in subalpine zone in the high mountains, between 1. Once there are no lice, so ankmals is no forest, we talk about alpine zone in high mountains. On the other hand, shrubs are uncommon in both biomes, being the most of them smaller and creeping. That way, they can protect themselves against heavy frosts and cold winds, because they get covered of snow during the unfavourable period.

Cranberry bush Vaccinium vitis-idaea is a good example of this kind of shrubs. The herbs, bryophytes e. Due to cold weather and other restrictive factors of these biomes, plants have had to adapt in different ways. In these two biomes, the summer is the favourable season and is when plants can develop themselves. But in winter, unfavourable tbe, they can only remain dormant in the form of seeds or reducing their activity is blockchain a database a minimum, thus avoiding own energy consumption.

For all these, these plants produce storage organs below ground, where they are protected from cold temperatures. Examples are rhizomes underground stems, usually elongated and with horizontal growth, root-like and bulbs short and thick stem, covered with more or less developed fleshy leaves. These bodies ensure sufficient energy reserves during the unfavourable period.

Furthermore, their roots are thick and can also accumulate reserves. On the other tue, their capacity to reach new zones to live, new habitats, depends more of the vegetative reproduction what plants and animals live in the arctic tundra asexual reproduction, that is, the emission of buds, underground organs, etc. And, in particularly, it is favoured by a high number of buds plant organ that, when is developed, forms a stem, branch or flower.

A very curious adaptation, ehat can also protects against the wind, is that some plants are cushion-shaped. This morphology allows moisture and temperature to increase within the plant, and therefore stimulates the development and facilitates photosynthesis. So, it makes very difficult to freeze the perennial parts those living all year. Moreover, their what plants and animals live in the arctic tundra cycle is also affected.

The favourable period is so brief that it is often impossible to grow, forming flowers and fruits in the same year. Therefore, the plants usually live longer than a year and tend to perform only one of these three functions during the favourable season. Then remain dormant during unfavourable weather. Thanks to all these adaptations, plants have managed to live in such extraordinary places like these acrtic, as incredible survivors.
