Doroshenko K. The ecological parameters of the spring ephemeroides cenopopulations in the beech biogeocoenosis and their indication meaning (on the north-western Podillja exampel).

The objects are the spring ephemeroides cenopopulations as a population indicators of the state of beech forest biogeocoenosis and derivative associations in them place. Tha aims are to study of structurally-functional parameters of the spring ephemeroides cenopopulations in the beech biogeocoenosis and their under antropogenous impact and to founding their indication meaning. The methods are the generally accepted methods of cenopopulation researches, packages of softwares of Stat Soft, Statistica version 6. As a result of investigations the possibility of using of some structural parameters of the spring ephemeroides cenopopulations (Galanthus nivalis and Corydalis solida) for indication of the state of beech forest biogeocoenosis (in the different conditions) was proved. Some parameters of G. nivalis cenopopulations are informative indicators of the state of beech forest biogeocoenosis under antropogenous impact (protected area, farm and forestry, felling), some parameters of C. solida cenopopulations - under the uncontroled recreation impact, because they can stay in the communities even on the last stages of degression. Application spheres are phitomonitoring and training courses.
