"The ecological and biosystematic studies devoted to the closely related species and hybrid complexes allow us to understand better the mechanisms of their evolution and success in the selective processes. The detailed examination of selected cases is also important with respect to recent emphasis on biodiversity protection. The members of polyploid complex of Hieracium subg. Pilosella may serve as a unique case where recent hybridization is connected with the formation of apomictic stabilized types which characters may be related to habitat factors. Plant community may function as habitat factor, its structure we consider as selective factor influencing the size of plants and the type of clonal growth. The research will be focused on conditions allowing the hybridization and hybrid establishment, study of their reproductive systems, and detailed domparison of apomictic and sexual cytotypes."@en . . .
