Ecological Hustlers: 7 Plants And Animals Who Were Phenomenal Aggressors

For millions of years of evolution animal, plants and birds in different corners of light haven't bad adapted to each other. And let someone was and there is the hunter, and someone — production, in general the ecosystem is in balance. But sometimes on the horizon there are aggressors who breed and extend many times quicker and more effectively, at the same time feeling just perfectly in any conditions. And most often there is it because of the person …

Heracleum looks horribly — not a grass, not that tree: gear leaves, huge inflorescences, in height to three meters. It is considered that he under the personal decree of Stalin was brought to a midland of Russia from Georgia in post-war years when there was sharply not enough forage for the cattle. Then the cow-parsnip was planted on experimental fields. Cows who consumed a silo from a cow-parsnip milked more, however, his tastes suffered and it was fermented worse. Therefore the invention with a plant was thrown. The cow-parsnip, however, not only hasn't withered, but also has begun to live the productive life, having captivated fields, waste grounds and roadsides of roads. The plant was not only trudnopobedimy (for example, to mow it it is useless), but also poisonous: his juice which has got on skin to sunny day can cause severe burns. At the same time there is a mass of local ways of lime a cow-parsnip. For example, to cover the field for a year with lightproof material. Perfectly also herds of sheep fight against the growing-up cow-parsnip. But it is impossible to destroy a plant at once in extensive territories so far.

This amphibious which largest copies reach in the weight of 2 kg and can quite eat carcass of a kangaroo for couple of days, it has been delivered to Australia from South America in 1935. Local farmers hoped that the toad will help them with fight against insects wreckers. They have miscalculated: I have aha become interested absolutely in other "products". At the same time the toad is extremely poisonous, and this poison is deadly even to large animals, for example to dogs. Generally, many local animals have begun to perish in large quantities because of this amphibian. Meanwhile hordes of killing toads have moved deep into the continent. They have quickly adapted to new conditions, extremities have grown themselves more long and have fixed this new sign in the posterity. Per day aha can overcome up to 2 km. So far the Australian authorities puzzle over what to do, huge populations of toads occupy all new and new territories where they almost have no competition.

Lovely big-eared creatures which meat at us is considered a delicacy cause to the environment considerable damage too. First of all in Australia where in the 19th century one farmer has set free 24 gray rabbits. Those have begun to breed and destroy actively vegetation, and in the 1930th years the situation has got out of hand so that the authorities had to use biological weapon — a virus of myxomatosis with which infected water. 10% of individuals have developed immunity and have transferred it to krolchata, but now population of wild rabbits somehow manages to be controlled. By the way, for the same purpose also the huge mesh fence — the biggest in the world has been built. All this action had also a negative side — so, local eagles and wild cats have managed to get used to rabbit flesh in the menu, and having lost a rich dish, have begun either to perish, or to switch to birds, sometimes very rare. The angry authorities have tried to hunt cats, but the number of rats has immediately grown.

In the middle of the last century the plant was delivered in the USA and began to be advertized actively as means of fight against an erosion of soils. Whether the American farmers haven't understood how it is correct to look after for a kudza, whether in new conditions the plant has just got out of hand, but for only a few years the newcomer has so extended across the territory of several Eastern States that many in all seriousness considered it revenge of Japanese for nuclear bombings. Literally in a year the two-storeyed house can turn a kudza into the green hill without hint on windows, doors or a roof.

Zmeegolov has been found in the Far East, his meat seemed to people so tasty that unattractive, with a terrible grin, creation has been decided to part this in reservoirs of other countries. It has become clear that the equipped reservoirs weren't so necessary: zmeegol it is so hardy that will perfectly feel even in a muddy pool. Manufacturers and the fact that this strange fish can easily be on the land up to five days haven't considered and creep from one reservoir in another. In length fish reaches meter, can long be in an ambush, easily kills snakes, and even large predatory fishes.

Gray squirrels have got to England from the USA and at once haven't bad accustomed in the neighbourhood with primordial inhabitants of the Foggy Albion — red squirrels. But gray were much larger and more gluttonous and also is more inventive in search of a forage and it is much more courageous. Besides, the American guests have a special squirrel virus to which at red there was no immunity. As a result population of red squirrels began to be reduced promptly. The British authorities had to equate gray having a tail to wreckers and to open on them the most real hunting. Moreover, protein began to be eaten, and even to serve their low-fat meat dishes at some restaurants!

This Asian small fish of family of Karpov was delivered in the USA for cleaning of ponds. The matter is that by means of the tsedilny oral device the silver carp filters the blossomed, green and muddy water. After one of floods the silver carp has got to the basin of Mississippi, and here it became clear that from a gluttonous carp there is more harm, than advantage. First, fish eats all forage without remainder, leaving competitors on short rations. Secondly, the silver carp reaching meter and more in length was awfully timid. Having caught the boat motor, fish jumps out highly of water and can even overturn the watercraft therefore the American fishermen have begun to shoot these fishes from arbalests, but meat them at the same time don't eat.
