Ученые заявили, что березы "ложатся спать"It is established that birch at night change their position.

Birch go to bed and night is inclined at 10 cm — to such conclusion of botany, published an article in Frontiers in Plant Science.

They first only described changing the position of the branches of the tree during the night, but also showed the possibility of a ground 3D laser scanning.

Researchers from Finland and Austria explored the nocturnal movements of the branches of the silver birch.

The peculiarity of this experiment was that the scientists simultaneously conducted their measurements separately in each of these countries at the same time of the year. They compared the indicators to understand whether these features of regional or place with trees all over the world.

It turned out that trees also have circadian rhythms and at night, change their position, drooping branches. Data with a precision of millimeters were obtained through terrestrial laser scanning.

The researchers attribute this to the lack of sunlight, which daylight hours are stretching branches of trees.
