Elmhagen, B., Ludwig, G., Rushton, S.P., Helle, P. & Linden, H. (2010) Top predators, mesopredators and their prey: interference ecosystems along bioclimatic productivity gradients. Journal of Animal Ecology 79 , 785–794. 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.
