One example is the presence of multiple predators, particularly generalists that are attracted to a given prey species if it is abundant and look elsewhere if it is not. [149] As a result, population cycles tend to be found in northern temperate and subarctic ecosystems because the food webs are simpler. [ 150 ]
Hyperpredation has been recorded in an ecosystem involving a bird (native prey), a cat (alien predator), and a rabbit (alien prey). Hyperpredation, also known as hypopredation, is when a generalist predator increases its predation pressure as a result of the introduction of a substitute prey. [1]
A cheetah exhibiting pursuit predation. Pursuit predation is a form of predation in which predators actively give chase to their prey, either solitarily or as a group.It is an alternate predation strategy to ambush predation — pursuit predators rely on superior speed, endurance and/or teamwork to seize the prey, while ambush predators use concealment, luring, exploiting of surroundings and ...

For example, the hemipteran Arachnocoris berytoides resembles Faiditus caudatus, a spider commensal of ants. [34] In cryptic aggressive mimicry, the predator mimics an organism that its prey is indifferent to. This allows the predator to avoid detection until the prey are close enough for the predator to strike, effectively a form of camouflage.
Steve Sapontzis, in his 1984 paper "Predation" argues against the idea that the problem of predation is a reductio ad absurdum for animal rights, instead, he claims that if we accept the view that we have an obligation to reduce avoidable animal suffering, then predation is something that we should work towards preventing if we can do so ...
A strawberry aggregate accessory fruit damaged by a mouse eating the seeds ().. Seed predation, often referred to as granivory, is a type of plant-animal interaction in which granivores (seed predators) feed on the seeds of plants as a main or exclusive food source, [1] in many cases leaving the seeds damaged and not viable.
An example, which has caused much trouble in Maryland and Florida, is the snakehead fish. [ 5 ] Predatory fish such as sharks , billfish , dolphinfish and tuna form a part of the human diet and are targeted by fisheries , but they tend to concentrate significant quantities of mercury in their bodies because they are high in the food chain ...
