Search asks: Why roaring lion and Amu cat?
German results were considered new and unexpected for scientists and specialists
Seems that the lion's roar or the household cat meow
Has to do with the place of living for these animals more than his relationship size
According to modern scientific research.

The new research analyzed the voices of 27 species of the genus cats
Large and small
In order to find out why vary vary depending on the environments in which they live
Of open desert spaces
To plant forests dense.

The scientists found that cats that live in the open
Launches deeper voices of those living in crowded places.

The previous scientific research has indicated
That the size of cats is determined by class voice
The goal is to identify the female or male
For the purposes of the defense of the influence.

The research analyzed
Conducted by Dr. Gustav Peters and Dr Marcell Peters
Research Center in animals garden in Bonn, Germany
Overall average for long acoustic waves launched by 27 different kinds of cats.

Audio analysis
The analysis included voice sounds big cats
Such as lions, cheetahs and leopards
It cats capable Roar because of its configuration in the voice praises.

Then the researchers then trying to find a link between those voices and the size of those cats
The presence and living areas in their environment.




Votes cats have nothing to do with size, but to the environment
And show them that the cats that live in the open areas of the environment
Such as lions and forth from similar animals, launches deeper voices.
The cats that live in dense plant environments
Such as wild cats, tigers, etc.
Communicate with each other through the voices of high-class voice by peace or peace here.

These results are considered
Published in the journal Biology specializing unexpected for specialists.
The researchers said that most studies have examined
The question of the transmission of audio signals for animals in dense habitat
Showed that low voice classes is the strongest and the most prominent.

An example of this is uncovered by a previous study
That sounds high layers break down and get lost in the intensive plant environments.

The same effect occurs for low acoustic layers in open-space environments
But that does not explain why roaring lions deep voice.

One explanation says that the big cats like lions, for example,
Are inherently issued voices deep and low voice layers
This explains the difference between the lions roar and cats meow small home.

But researchers Germans due to genetic inheritance each never Dersah in the search
They found that the size and weight has nothing to do with them to determine the quality of votes
Or depth or degree of height or decline.
