Determination of minimal area
WebAbstract. Current methods for the determination of the minimal area of a phytocoenosis are compared. A new method is described. It is based on the increase in average quantitative similarity between plots in series of nested plots of increasing size in relation to species richness and dominance relations. A simulation model composed of coenotic ...
