"This\u00A0grant proposal is aimed at increasing of our knowledge on the microevolutionary processes that shape the population structure in diploid - polyploid angiosperm alliances, taking Aster amellus, Campanula gentilis and Pimpinella saxifraga as model groups. Multidisciplinary approach using a wide array of current biosystematics and ecological methods (flow cytometry, molecular techniques, demographic analyses, experimental cultivation, etc.) will be adopted. Hitherto neglected issues of polyploid formation, establishment, and population dynamics will be in the project spotlight (population-level investigation of unreduced pollen grains production\u00A0and its microevolutionary role, assessment of differences in life history and demographic traits between ploidy levels, exploration of cytotype-specific responses to mycorrhizal symbiosis and phytophagous insect attack, etc.). Long-term observation of cytotype ratio fluctuation in sympatric populations will also be initiated. In addition, novel"@en . "2006-01-01+01:00"^^ . "0"^^ . " sympatry" . . . . "1"^^ . .
