What are the trees in the rainforest shy about. Tree crown shyness is an unusual natural phenomenon What are trees in a rainforest shy about
Crown shyness is a phenomenon observed in some tree species where the crowns of fully developed trees do not touch, forming a canopy with gaps in the forest. Other names are canopy openness, canopy shyness, or canopy space. It is observed in trees of the same species, but cases have been recorded between trees of different species.
Scientists have not come to a consensus on the exact causes of "shyness", although this phenomenon has been discussed in the scientific literature since the 1920s.
According to one version, tall thin trees are damaged during strong winds, and in order to avoid colliding with each other, they react with “crown shyness”. Experiments have shown that trees gradually fill the gaps between the crowns if they are artificially limited from collision due to the action of the wind.
However, the Malaysian scientist Francis Ng, who studied Dryobalanops aromatica in 1977, found no evidence of friction damage on this tree and suggested that the apical growth zones are sensitive to light levels and stop growing when approaching other plants.
Another explanation is that "crown shyness" prevents the spread of leaf miners.

In the Malaysian forest research institute, tourists are told that the leaves emit ethanol, a gas that "drives away" the branches of neighboring trees from each other.
There are also parascientific versions related to bioenergetics. In 1939, the Krasnodar physiotherapist Semyon Davidovich Kirlian invented an original method of photographing objects in a high-frequency electric discharge. Particularly impressive were the photos of plants that created a special halo around them. They seemed to be surrounded by an aura. Surprisingly, it changed: a lone leaf "shone" in a completely different way than that surrounded by neighbors on a branch.
In the mid-1960s, Soviet researcher Viktor Adamenko, who was experimenting with the "Kirlian effect", discovered that a cropped sheet looks intact in a Kirlian photograph. Later, University of California professor Thelma Moss repeated this experiment and became convinced of the reality of a strange phenomenon. And the Brazilian researcher Ernani Andrade modified the experience somewhat. He did not cut off, but killed part of the sheet and got the same result.
What are "glowing phantoms"? Don't they indicate that a living plant is permeated with some kind of energy "framework", which disappears only after its death as a whole? And can "crown shyness" be caused by this phenomenon? The question remains open.
