  1. 16. Physical and biological dispersal barriers in invasive, bloom-forming microalgae

    Författare :Ingrid Sassenhagen; Enhet akvatisk ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dispersal barriers; microalgae; phenotypic differentiation; population genetics; priority effects;
