Raccoons (Procyon lotor) and skunks (Mephitis mephitis) are mesopredators.Here they share cat food in a suburban backyard.. The mesopredator release hypothesis is an ecological theory used to describe the interrelated population dynamics between apex predators and mesopredators within an ecosystem, such that a collapsing population of the former results in dramatically increased populations of ...
As described by Paine in 1966, some sea stars (e.g., Pisaster ochraceus) may prey on sea urchins, mussels, and other shellfish that have no other natural predators. [19] If the sea star is removed from the ecosystem, the mussel population explodes uncontrollably, driving out most other species. [4] These creatures need not be apex predators.
When populations of an apex predator decrease, populations of mesopredators in the area often increase due to decreased competition and conflict with the apex predator. [2] This is known as the mesopredator release effect , which refers to the release of mesopredators from the trophic cascade . [ 5 ]

An apex predator, also known as a top predator or superpredator, is a predator [a] at the top of a food chain, without natural predators of its own. [ 6 ] [ 7 ] Apex predators are usually defined in terms of trophic dynamics , meaning that they occupy the highest trophic levels .
Riparian willow recovery at Blacktail Creek, Yellowstone National Park, after reintroduction of wolves, the local keystone species and apex predator. [137] Left, in 2002; right, in 2015. The elimination of wolves from Yellowstone National Park had profound impacts on the trophic pyramid. In that area, wolves are both keystone species and apex ...
