[Some problems of the study and representation of Siberian flora biodiversity in connection with its conservation].
The present knowledge of flora of Siberia is quite insufficient, which is a considerable obstacle to the detection of its biodiversity for conserving the gene pool. Planning conservation measures should be focused not only on species, but also on intraspecific taxa and their phylogenetic uniqueness. In the absence of genetic data, available morphological and geographical methods should be used, so that, when it is impossible to establish the actual origin and relationship of taxa, the existing morphological diverstity is at least represented, as far as it is known to be based on genetic diversity. Phenetic maps can be of much use in the study of intraspecific morphological diversity. The estimation of geographic variability and morphological diversity, as well as the evaluation of territories, can be based on such maps. To represent adequately the biodiversity existing within poorly studied, presumably hybrid plant groups, until actual origin and relationship are known, they should probably be forcedly and provisionally considered as a special type of hybrid complexes, representing the unclear present day taxonomic situation. Such complexes could include populations and individuals with morphological characters of two or more different species, until the systematic position of such populations and individuals is further explored. Until the actual taxonomic status and relationship of the components are established, they could be regarded as subspecies permitted by the Code, or as certain recorded morphological deviations from the type, without assigning any taxonomic status to them--depending on the available data on variability and distribution. In the future, the resulting provisional information on morphological diversity would help to concentrate the efforts of biologists, in possession of the newest methods, on the most important objects, and serve as the scientific base for effective measures aimed at the conservation and management of the vast gene pool of the Siberian flora.
