Annotation: The project aims at study of determinants of species rarity in thethree model groups from the family Asteraceae (Tephroseris longifolia agg., Cyanus napulifer group and Pilosella alpicola group) by comparing various biological traits and genetic diversity of the rare (often endemic) and widespread congeners. A combined approach including geneticanaly sesemploy in ghighly variable molecular markers (AFLP, SSRs) as well as analyses of fitness, ecological niche and spreading potential (by common garden experiments, GIS digitallayers, soil analyses) will be applied. Results of the project will bring valuable information on specific factors determining range size in selected plant groups from Asteraceae family, but also help to find common features and more general regularities in unravelled patterns and processes. Moreover, outputs of this project will serve as a baseline for conservation recommendations as each of systematic groups investigated harbours also taxa endangered by recent human activities.
