That's what happens when you run the wolves in the forest, where there are too many deer ... sometimes nature is cruel!

Scientists are confronted daily with some openings, but one of the greatest scientific discoveries of the past 50 years is a trophic cascade.
Trophic cascade effect - it is the energy law prevailing in the ecosystem where the living organisms that are "above" eat those who are "below". Herbivores eat plants, they, in turn, eaten by predators, and those predators eat stronger predators.
Any wolf, for example, will not give up fresh venison. How strange it sounds, but the wolves eating deer meat, helps to save the lives of many members of the animal kingdom.
70 years ago people killed all the wolves in Yellowstone National Park. In this way, they wanted to increase the number of reindeer. But people are not able to control the process of the deer population - and this has led to the uncontrolled proliferation of these mammals, which caused great damage to the flora of the park.
But in 1995, the year in Yellowstone Park wolves launched. Incredibly, this has helped to upgrade the entire ecosystem of the park. This is a major influence on the behavior of horned. The deer began to avoid places where they could supposedly get to the wolf in the trap.
Wonderful way these territories began to revive. The number of trees has increased 5 times. Barren land turned into dense forests where new species have settled.
In the diet of wolves and coyotes included meat. This has helped increase the number of mice and rabbits, which in turn led to the park foxes, weasels, owls and eagles. The local forests are also back the bears, which again could enjoy the taste of fresh, berries growing on the trees.
What's the strangest thing - the emergence of wolves has affected even the course of rivers. Reduced bank erosion, stream meandering rivers straightened and stabilized.
Wolves is not just changed the ecosystem and cool We changed the entire local topography. Perhaps you did not think, but that's because we affect the environment around us, part of which we are. Be more responsible - tell us about this natural paradox your friends!
