  7. 25. Eutrophication effects on a coastal macrophyte community in the Bothnian Sea

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Emilia Linder Wiktorsson; [2021]
    Nyckelord :eutrophication; macrophytes; opportunistic algae; Baltic Sea; Bothnian Sea;

    Sammanfattning : Eutrophication is a major concern in the Baltic Sea and it is affecting macrophyte communities by promoting the growth of opportunistic algae and decreasing the cover of perennial macrophyte species via shading. It is however uncertain how common eutrophication and its symptoms are in the northern parts of the Baltic Sea, the Botnian Sea. LÄS MER
