A herring in the North Sea, a crab in the Wadden Sea or an anemone fish on a coral reef, ... biologists like to think in terms of individual species that all have their own place within food webs in ecosystems across the world."But that is surely too simplistic thinking," NIOZ researcher Ana Born-Torrijos and colleagues warn in this month's cover story of the scientific journal.
"In the review article, the researchers describe how an animal's stable isotope values may differ depending on whether they are infected with parasites or not."That's because parasites can change the behavior of a host, even without making that host really sick. For example, a coral fish infected by a specific species of isopod, appears to forage much less outside the reef than uninfected individuals of the same species.
