Fig 1. Proportions of unique and clonal ramets in Baltic Sea Fucus vesiculosus and F. radicans populations.

Unique genotypes are sexually recruited or rare clones. Clonal ramets are all asexually recruited. Salinities are indicated in Practical Salinity Units. F. vesiculosus populations are marked in red and italic letters, F. radicans in green and regular letters, and four unassigned populations (see text) are marked in blue and underlined letters. Populations of the two species having the same letters are sympatric.
