- Аннотация: VALIDATION OF THE ECOLOGICAL-COENOTICAL GROUPS OF VASCULAR PLANT SPECIES FOR EUROPEAN RUSSIAN FORESTS ON THE BASIS OF ECOLOGICAL INDICATOR VALUES, VEGETATION RELEVES AND STATISTICAL ANALYSIS. The original approach for finding, testing and analysis of ecological-coenotical plant species groups (ECG) is proposed. The approach has been tested on the ECG system for the vascular,plants of European Russian forests developed earlier by O. Smirnova and L. Zaugolnova with contribution of O. Evstigneev. The ECG system is an extension of A. Nitsenko ECG system (1969)and G. Zozulin historical suites (1970, 1973). Seven species groups of the system were obtained on the base of expert knowledge, and thus their verification by formal methods was desirable step. Ecological and coenotical species features for quantitative analysis were presented as variables of two types: (1) EUenberg indicator values and (2) species scores derived from ordination of vegetation plots. The ordination was conducted by non-metric multidimensional scaling (NMS)technique and ordination scores for the species were calculated by weighted averaging of the plots coordinates. Further, discriminant analysis (DA) was used to identify misclassifled species in ECG. DA was run repeatedly on the whole set of variables and on various subsets of them, with monitoring of results by experts on every step of the analysis. The procedure continued until a position of every species in the ECG system fits both DA results and expert judgment. Such joint expert-statistical approach allowed to greatly improve the ECG system, to put about 1000 vascular species into seven groups and to outline core species and intermediate species. It was also shown that the updated groups are homogeneous with respect to all variables under the study. The proposed methodology can be useful for improvement of any a priori species groups defined by either expert knowledges or traditional statistical methods such as cluster analysis.
