However, with the accession to the draft of the Great Arctic Reserve must change fundamentally, scientists say. Forest fires are helping to fight global warming? Scientists from the University of California, came to a surprising discovery. They found that small forest fires have a beneficial effect on the ability of forests to absorb carbon dioxide. Their study, researchers conducted a California’s reserves. It turned out that at present the forest of California annually processed about 50 million tons of carbon dioxide, which is approximately 14% of its total amount absorbed by all U.S.
forests. Since the beginning of last century the rate of processing carbon dioxide decreased by 34%. This was due to the fact that the amount of absorbed carbon dioxide depends on the size of the tree. Recent data suggest that percentage of old, and, respectively, and large trees in forests has decreased significantly. Why? Just under the laws of nature reserves must extinguish all fires, including the smallest one. But the small fire, that can result, for example, lightning strike, carried out in the woods cleanup function. Burnt out new growth, which prevented the growth of large trees.
Putting out fires all the same led to the overflow timber young trees. This adversely affected the larger trees – they have become more vulnerable to drought and pests. Scientists have discovered how insects breathe underwater scientists from MIT to figure out how way many species of insects and spiders that inhabit the large depth, breathe freely under water. It turns out that when immersed in water on the shell of these insects is delayed air, shrouding all the insect’s body a kind of bubble. The properties of this bubble is unique: it is not only the ‘feeds’ the insect with air, but adds to it, absorbing the new number of air bubble from the surrounding water. No small role in respiration of insects under water are hairs on their body: they determine the pressure that can sustain this air bag. Due to the air that lingers in the hairs, the insects can dive to a depth of 30 meters and carry out underwater quite a long time, for example, through the winter. The sensation of the week: China’s pig pig gave birth to a mutant monkey head and a conclusion of our review, we present you the news that the maximum read number of visitors to our portal. And rezonanas in the discussion of the event was massive, not only on ECOportal.ru … On the Chinese pig farm pig gave birth to a mutant with a monkey head. Piglet with monkey’s head appeared on the light about two weeks ago and was the sixth in a litter of pigs, who lives on a farm for nine years. Instead of being born with a pig snout monkey, with two thin lips, small nose and two big eyes. His hind legs twice longer than the front, so the pig can not walk – just jump. And apparently it’s not a pleasant sight and is more suitable as a plot of a horror movie or science fiction. You never know what is in the pig could lead to this type of mutation. Cases of animal mating with a monkey scientists were not recorded. Photos of the mutant pig you can see on ECOportal.ru.
