    • نبذة مختصرة :
      The article reports that microscopic phytoplankton emit dimethyl sulfide when they are eaten by typical predators such as larger zooplankton. It mentions that anchovies eat the zooplankton, so penguins follow the dimethyl sulfide cue to find their fish food. It states that Juvenile penguins follow phytoplankton signal up the coast, but life-sustaining anchovies are no longer there, replaced by less nutritious goby.
