Predator‐prey interactions cause apparent competition between marine zooplankton groups
Abstract Predator‐mediated apparent competition is an indirect negative interaction between two prey species mediated by a shared predator. Quantifying such indirect ecosystem effects is methodologically challenging but important for understanding ecosystem functioning. Still, there are few examples...
