In a world becomes warmer every year, the Arctic Tunz is increasingly reminiscent of the forest. This process, called the saving method, is especially pronounced in Eurasia and in the Arctic mountains.
His speed was assessed by a new large -scale study, based on data from 1,100 options across the Arctic Bioma, its results were published in ecological letters.
Consequence
This trend is preserved, this can lead to some consequences – for example, accelerating murmur melting or changing the seasonal migration of the northern deer. It can also affect the traditional way of the indigenous people of their lives.
When the shrubs and other species like other plants expand, they delay more snow in the winter and cover the earth in the summer. This changes the soil temperature and may increase the melting speed of the permanent ice. Therefore, a large amount of carbon can be released, has been frozen for thousands of years, contributing to global heating.
However, research shows that the consequences of climate change are complicated and unpredictable.
We find that the enthusiasm is the strongest near the boundary of the forest, in warm and wet places, as well as in areas with limited climate change. This shows that the enthusiasm does not necessarily occur when the heating is the largest, and the most favorable conditions for the roots, Mr. Anna Bjorkman said.
Most notably in Dalarne
In Sweden, the trend is more noticeable in the Dalarna mountain range in the south of Abiska's northern mountains, which plays a typical example of the ability to accelerate the drilling. In addition, the continuous spread of forests to mountainous areas may have some consequences.
Lichens can disappear in the shade of bushes, reducing the food facility for the northern deer on the mountain. This, in turn, can affect the lifestyle of cattle, changes deer migration routes and reduce access to traditional factories.
Some animals, such as deer horns, red foxes, sea lilies and forest fields, can settle in a new living environment and thus affect the ecosystem.
The spread of Lingonberries
The study also analyzed features that allow a number of factories to spread more successfully than other features. It shows that lower Boreal species grow easier to grasp the higher rules. In addition, herbs and shrubs invade more territorial areas than flowers, partly due to the more effective absorption of nutrients from the soil. Some examples of the Northern species manage to reside in a large number of territories are a container of Bigelou and Lingonberries.
This shows that in order to spread plants on alien lands, it is not enough warmth alone, a certain level of adaptation to the environment is necessary.
