| complex distribution patterns, ecology and coexistence of ploidy levels of allium oleraceum (alliaceae) in the czech republic. | despite extensive study of polyploidy, its origin, and ecogeographical differences between polyploids and their diploid progenitors, few studies have addressed ploidy-level structure and patterns of ecogeographical differentiation at various spatial scales using detailed sampling procedures. the pattern of coexistence of polyploids in the geophyte allium oleraceum at the landscape and locality scale and their ecology were studied. | 2010 | 20363760 |
