In this research we study the ecosystem where the brown algae Lessonia traberculata, known as "palo" in our coastline, develops. The brown algae (= phaeophytes) are almost exclusively found in marine waters. They are very abundant on rocky coasts where they grow in the littoral zone (the zone from high tide to low tide) and sublittoral zone, especially in cold, agitated and well aerated waters. Brown algae are important primary producers in these...
