Clonality, polyploidy and spatial population structure in Baltic Sea Fucus vesiculosus.

ABSTRACT: Genetic characteristics of populations can have substantial impacts on the adaptive potential of a species. Species are heterogeneous, often defined by variability at a range of scales including at the genetic, individual and population level. Using microsatellite genotyping, we characterize patterns underlying the genetic heterogeneity in marine macroalga Fucus vesiculosus, with a particular focus on two forms: attached and free-living. Here we demonstrate that sympatric populations representing the two forms display marked differences in characteristics of reproduction and genetic diversity. Asexual reproduction was ubiquitous in the free-living form despite being almost entirely absent in the attached form, while signals of polyploidy were common in both forms despite the distinc
