Ecological analysis of the medicagini-festucetum valesiace wagner 41 association present on the romanian territory

Abstract

The analysis of the ecological requirements of the Medicagini-Festucetum valesiacae phytocenoses present in the Romanian territory, has a great importance since it provides information concerning the evolution of the ecological relationships from a region, across historic time, but also about the species migration from certain origin areas and subsequent integration in groups similar to those identified. The spectral analysis, using the ecological species indices, has shown certain particular characteristics of the phytocenoses, with regard to the geographical area which they underlie.
