Long‐term responses of zooplankton to invasion by a planktivorous fish in a subarctic watercourse
Summary 1. Introduced or invading predators may have strong impacts on prey populations of the recipient community mediated by direct and indirect interactions. The long‐term progression of predation effects, covering the invasion and establishment phase of alien predators, however, has rarely been...

Increased predation pressure following the vendace invasion induced many effects on the crustacean zooplankton, and we document comprehensive and strong direct and indirect long‐term impacts of an introduced non‐native predator on the native prey community.
