The loss of primary, or "apex" predators is causing an explosion in secondary, or "mesopredators" around the world, a new study concludes. For example, the extermination of wolves may allow coyote populations to surge, which in turn can suppress feral cat populations, leading to more rodents, etc. These cascading effects are poorly understood but are causing ecosystem disruptions around the world, scientists say.
