title: Red in tooth and claw: how top predators shape terrestrial ecosystems.
abstract: Top predators are increasingly recognized as important regulators of ecosystem structure. Elmhagen et al. in this issue show how a recolonizing population of lynx in Finland is in the process of imposing control of the abundance of a mesopredator, the red fox, and relaxing predation pressure on a prey species. Their study shows how ecological restoration programs could use the power of top predators to limit mesopredator populations and control total predation pressure on prey species.
