Contribution of clonality to D. lineata populations at 8 sites across the North American Atlantic Coast. Clonal dominance (D_rare) normalized to rarified genotypic richness, reflects the relative diversity of MLGs at a site. Low values occur at sites dominated by a few large clones. High values occur where all MLGs are represented evenly. Where D = 1, every MLG is represented by a single individual. Solid upper and lower lines indicate maximum and minimum D_rare possible for a given MLG richness. Dotted line is the median D_rare expected if the number of ramets per genet is random within each level of genotypic richness. Point color indicates site. State code in parentheses indicates the region of origin.
