Abstract

A tree is a stationary living thing. Its crown, trunk and roots are capable of reacting to environmental factors; some parts of the tree receive signals from the surroundings while others react to them. The long-lived Pinus longaeva integrates these ever-changing stimuli over 5000 years, the short-lived Populus alba only 50. This ability to integrate is reflected in many different kinds of tree characteristics, such as geographical distribution, tree crown and tree rings. In the course of evolution plants have developed on every site, being best adapted to the particular conditions obtaining there.
