Abstract: Diatoms are one of the most diverse and abundant phytoplankton taxa and are highly important as primary producers, accounting for nearly half of the marine primary production and constituting the base in the marine food web. Despite their high dispersal potential they are genetically diverse and display genetically structured populations. The high genetic diversity enables quick adaption to changes in the environment. The ocean is a dynamic habitat, changing rapidly in e.g. temperature, nutrie... more
