  3. 2. Phytoplankton defense mechanisms against grazing : the role of grazing infochemicals

    Författare :Veronica Lundgren; Edna Granéli; Takeshi Yasumoto; Aaron Barkoh; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Akvatisk ekologi; Aquatic Ecology;

    Sammanfattning : Many phytoplankton species have evolved a variety of different defenses to decrease losses from grazing; morphological features, changes in life-history/behavior, and production of toxins. These defenses may be associated with costs. Therefore, some phytoplankton only express the defense when needed, i.e. LÄS MER
