The largest and the smallest animals are more at risk of disappearing, it is told in the results of the latest study done in the United States of America. 

If the problem relates to the extinction of vertebrates, the volume has significance. 

But zoological typical values, who got into the so-called "area of life", have nothing to worry about - they are not threatened by loss in any way. In this case, the period, as well as large animals, are near the danger of c-due to their fishing, small varieties suffer from the clogging of the boron felling around the sphere as well. 

"For the purpose of the largest vertebrates, the maximum danger is assumed by homicides produced by humans," said members of the team of scientists near the office of environmental scientist Bill Ripple from the Oregon Institute in the United States of America. "In this case, after all, the period, tiny animals often have a narrow sphere of distribution, what is considered one with significant characteristics of the notch disappearing, also have every chance of being subjected to extinction with-due to degradation of the habitat." 

According to scientists, animals die in this large number, that similar characteristics have every chance to serve as a reason for the prediction of complete bio varieties. 

This sent experts to study the basic conditions that have an impact on the disappearance of animals. 

The source for the guess is the volume of the vertebrate trunk. Studies of birds and mammals have revealed that large animals are more susceptible to degeneration. Large animals, drawings of which are used by functionaries of nature conservation movement for the purpose of campaigns according to the protection of nature - such as elephants, rhinos and lions, have long been under the supervision of protection organizations located around the sphere. 

But zoological, birds, reptiles are also the largest toads, similar as well as the whale whale, the Somali bird is also a strange big newt, they do not give any special significance. Without having previously expressed themselves in any way about such small types, as well as croakers are also shrews, in which they practically do not concentrate interest in any way. 

"In my opinion, first of all, in general, it is necessary to focus interest in small animals, due to the fact that large cranial ones use huge fame, in this case, the period as well as small types of this is not enough in any way," the scientist Ripple added.
