Warmer winters and great snow cover in the Arctic north kills plants

Occurring on our planet climate change is leading to warmer winters in the Arctic region. A warmer winters help to increase the amount of precipitation and snow cover in this part of the world. It would seem — all pretty bad, because the snow cover protects plants from cold in winter, maintaining a suitable temperature, and promoting early plant growth. However, all is not good for arctic plants

How do I find European scientists snowfall promote intensive growth of pathogenic fungus that infects plants hiding under the snow. For many years, scientists have been studying the ecological processes that occur beneath the Arctic snow. With snowfence each year for seven years, scientists have increased the layer of snow on the experimental site, and almost all the observations reported increased plant biomass under the snow cover, which confirms the usefulness and necessity of the snow blanket for plants of the Far North.

What was surprising scientists when already in the sixth year of the experiment guinea plant crowberry, or crow berry (Empetrum hermaphroditum) was destroyed by a fungal disease. The culprit was a mushroom Arwidssonia empetri ksilyarievyh group of fungi. Scientists explain that the increased thickness of the snow cover makes for fungi ideal microclimate conditions that would eventually become the cause of the epidemic in the snow for northern plants Kompyulenta notes.

Biologists believe that this extinction of vegetation in the Arctic can not only lead to increased greenhouse gas emissions due to the decomposition of dead plants, but also a major change in the food chain of the Arctic tundra ecosystem, according to RIA Novosti.

Specialists note that the results of their research to help you better understand the relationships between plants and other organisms, and to evaluate the effects of climate change and extreme weather to extreme ecological communities.
