- Apex predators can alter food webs through direct mortality on prey and via risk effects that can induce plastic and/or genetic alterations in prey traits, including changes in prey behaviour [2, 3], morphology, life history and physiology. Such risk effects can also initiate trophic cascades.

Aug 3, 2024 · The presence of apex predators also encourages niche differentiation among prey species. When predators hunt specific prey, they can influence the prey’s feeding habits, reproductive strategies, and habitat use.
Aug 8, 2022 · Apex predators occupy the highest trophic positions in food webs and serve profoundly important roles in ecological and evolutionary processes, shaping and re-shaping the traits of prey and how they interact with one another and the ecosystem.

Jan 26, 2022 · Predators can impact prey via predation or risk effects, which can initiate trophic cascades. Given widespread population declines of apex predators, understanding and predicting the associated ecological consequences is a priority.
Nov 5, 2018 · Removal of apex predators can drive ecological regime shifts owing to compensatory positive and negative population level responses by organisms at lower trophic levels. Despite evidence that apex predators can influence ecosystems though multiple ecological pathways, most studies investigating apex predators’ effects on ecosystems have ...

Mar 13, 2023 · Prey availability is especially relevant in a scenario of apex predator restoration where responses to competition by subordinate predators could be more complex than just fear or death...
Apex predators affect prey species' population dynamics and populations of other predators, both in aquatic and terrestrial ecosystems. Non-native predatory fish, for instance, have sometimes devastated formerly dominant predators.
Aug 13, 2009 · Removal of apex predators can result in changes to intraguild interactions and outbreaks of mesopredators (‘mesopredator release’), leading in turn to increased predation on smaller prey. Here we provide a review and synthesis of studies of predator interactions, mesopredator release and their impacts on biodiversity.
