In the wild, most rain forest trees grow anything up to 400m (440yds) apart from others of their own kind, so that although any given area may be crowded with hundreds of different species, it usually has only a handful of specimens of any one type. What do scientists speculate is the reason for this?
of preventing one species from using all nutrients in the soil that they need thereby almost sterilizing the soil of those nutrients. Something like farmers alternating crops from year to year.
The trees are kept apart, scientists believe, by the very pests that prey on them. Detailed analysis of tree distribution have shown that most specimens are just far enough away from neighbors of their own kind to be beyond the flying range of the pests or disease-carriers which attack them.
One theory is that there is an inhibitory compound in the leaves of the parent tree that inhibits the germination of seeds of the same species within a specific area. There is a specific name/term for this and for the life of me I can not remember it -old age.
