Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host ) and parasitoidism (which always does, eventually).
Predation risk has long been recognized as critical in shaping behavioral decisions. For example, this predation risk is of prime importance in determining the time of evening emergence in echolocating bats. Although early access during brighter times permits easier foraging, it also leads to a higher predation risk from bat hawks and bat falcons.
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 ...
Trophic cascades are powerful indirect interactions that can control entire ecosystems, occurring when a trophic level in a food web is suppressed. For example, a top-down cascade will occur if predators are effective enough in predation to reduce the abundance, or alter the behavior of their prey, thereby releasing the next lower trophic level from predation (or herbivory if the intermediate ...
Predator–prey reversal is a biological interaction where an organism that is typically prey in the predation interaction instead acts as the predator. A variety of interactions are considered a role reversal. One type is where the prey confronts its predator and the interaction ends with no feeding.
The kittiwake nests on sheer cliffs that are almost completely inaccessible to predators, meaning its young are not at risk of predation like other gull species. [11] This is an example of divergent evolution. Another hypothesis for mobbing behavior is known as the “attract the mightier hypothesis.”
Suspects discovered by police in Edge at Lowry Apartments. During the torture, the armed individuals went back to the man and woman's apartment and burglarized it, Chamberlain said.
Prey switching is frequency-dependent predation, where the predator preferentially consumes the most common type of prey. The phenomenon has also been described as apostatic selection, however the two terms are generally used to describe different parts of the same phenomenon. Apostatic selection has been used by authors looking at the ...
