Predator-induced defenses differ between sympatric Mytilus edulis and M . trossulus

  title={Predator-induced defenses differ between sympatric Mytilus edulis and M . trossulus},
  author={Jeremy Lowen and David J. Innes and Raymond J. Thompson},
This is the first study to compare defenses to predation in closely related species of Mytilus and draws attention to the role of predation in determining their distribution, abundance and co-existence. We experimentally determined whether 2 blue mussel species, Mytilus edulis and M. trossulus, that co-exist within a hybrid zone in Newfoundland, Canada, differ in their predator-induced responses. Both species recognized cues from predators, although the magnitude of the responses to these cues… CONTINUE READING
