Apex predators reduce mesopredator populations and change mesopredator behaviors and habitat choices by preying on and intimidating mesopredators. [6] When apex predator populations decline, mesopredators can access hunting and den areas once controlled by the apex predators, essentially assuming the role of an apex predator. [ 2 ]
For instance, removing a predator may allow other animals to increase to the point where they wipe out other species; removing a prey species may cause predator populations to crash, or may allow predators to drive other prey species to extinction; and removing a plant species may result in the loss of animals that depend on it, like ...

“They are the only group of birds that achieved the role of terrestrial apex predators, evolving species that basically conquered South America during the Miocene (about 23.03 million to 5.33 ...
Living in open areas, pronghorns in general must rely on their eyesight to avoid predators, and with population numbers so low, the Sonoran pronghorn must avoid mortality at all costs. Sources of mortality come from predators, drought, and lack of feed; these sources usually affect fawns most often, and adult mortality also occurs in drought ...
