New paper: Native predator chemical cues induce anti-predation behaviors in an invasive marine bivalve
A new paper, coauthored with Kevin Hovel (San Diego State University), has been published in the journal Biological Invasions. We undertook an experiment to test how an invasive mussel responds to chemical cues from several novel native predators. We found that despite limited evolutionary history with native predators, invasive mussels respond with selective anti-predation behaviors and thus are not naïve to the threat of predation from native predators. These results provide new insight to the ‘naïve prey’ hypothesis and help explain the global success of a notorious marine invader. A PDF is available here.
