Top Predators Limit Their Own Numbers | IFLScience

Unlike small mammals who multiply like bunnies or some predators who’s boom or bust depends on said bunnies, large carnivores like lions and wolves keep their own numbers in check. According to a new work published in Oikos last week, population control is what distinguishes “apex predators” from the rest. Researchers have traditionally assumed that the densities of the largest of predators are determined by the availability of their prey supply, but recent studies seem to contradict a bottom-up control. And now, an international team led by Arian Wallach from Charles Darwin University proposes an alternate view: Apex predators naturally have the capacity to limit their own population densities—or self-regulate—helping to keep their ecosystems in balance.
