predator satiationとは 意味・読み方・使い方

Predator satiation (less commonly called predator saturation) is an antipredator adaptation in which prey occur at high population densities, reducing the probability of an individual organism being eaten. When predators are flooded with potential prey, they can consume only a certain amount, so by occurring at high densities prey benefit from a safety in numbers effect. This strategy has evolved in a diverse range of prey, from trees to insects. Predator satiation can be considered a type of refuge from predators.
