Fucus vesiculosus

Species biology: Fucus vesiculosus (Bladder wrack) is a foundation species in the North Atlantic and being essentially the only perennial species of macroalga present in the Baltic Sea. It provides important habitat for associated flora and fauna, contributing to maintain biodiversity in shallow rocky areas. Reproduces mainly sexually but occasionally is able to reproduce asexually by fragmentation.

Rationale for developing this model: The species shows extensive morphological and ecological variation among populations in which several cases show large genetic and chemical differences. It also characterizes by its high tolerance to large salinity gradients and desiccation and by its occasional clonal reproduction at low salinity.
