Phytozoenosis

from Wikipedia, the free encyclopedia

In a Phytozoenose ( give a wiki. Φυτόν Phyton "plant" and κοινός Koinos "together"), Phytocoenose , Phytozönose or plant community is there is a certain spatial detail of the vegetation or a derived type that has been abstracted from numerous such excerpts . Sometimes it is suggested to reserve the printout only for the specific characteristics and stocks, but this has not been generally accepted. In any case, phytozoenoses are manifestations of spontaneous vegetation, while stands assembled and planted by humans are not so designated.

The study of phytozoenoses is partly traditionally described as "phytozoenology", this expression is particularly common in the Russian research tradition ( Sukatschow ). In Germany one speaks of geobotany more often in the same sense .

In Central Europe, research into phytozoenoses is dominated by the methodology of plant sociology (founded by Josias Braun-Blanquet ), so that other research approaches are rarely used. The basic unit of vegetation here is the plant community . A single phytozoenosis (as a single stand) is represented by a vegetation photograph, i.e. H. the description of a sample area within a uniform stand that is recognizably different from neighboring stands. The plant community as a type can be derived from numerous such images by grouping and comparing them. In other countries and regions, other research approaches are sometimes predominant, e.g. B. the United States National Vegetation Classification (USNVC) in the USA. The controversy between the various scientific approaches is partly ignited by the contrast between more holistic approaches that view the types as recognizable, individual units, and those that emphasize the independence of the individual species in their ecology and distribution and therefore rather assume a continuum within the vegetation. Both research directions are approaching each other in more recent research. The main problem is that plant sociology works with non-randomly selected sample areas and therefore only allows the use of statistical methods to a limited extent.
