Spider wasps paralyse and eventually kill their hosts, but are considered parasitoids, not predators.. At the most basic level, predators kill and eat other organisms. However, the concept of predation is broad, defined differently in different contexts, and includes a wide variety of feeding methods; moreover, some relationships that result in the prey's death are not necessarily called pre

If predators learn while foraging, but do not reject prey before they accept one, the functional response becomes a function of the density of all prey types. This describes predators that feed on multiple prey and dynamically switch from one prey type to another. This behaviour can lead to either a type II or a type III functional response.
Potential competitors can also kill each other, in so-called 'intraguild predation'. For example, in southern California coyotes often kill and eat gray foxes and bobcats, all three carnivores sharing the same stable prey (small mammals). [26] An example among protozoa involves Paramecium aurelia and Paramecium caudatum.
A bear with a salmon. Interspecific interactions such as predation are a key aspect of community ecology.. In ecology, a community is a group or association of populations of two or more different species occupying the same geographical area at the same time, also known as a biocoenosis, biotic community, biological community, ecological community, or life assemblage.
Predators including Cactoblastis cactorum (mentioned above) can also be used to destroy invasive plant species. As another example, the poison hemlock moth (Agonopterix alstroemeriana) can be used to control poison hemlock (Conium maculatum). During its larval stage, the moth strictly consumes its host plant, poison hemlock, and can exist at ...
Some examples of this include predator–prey interactions, host–pathogen interactions, [2] and brood parasitism. [3] In exploitative interactions, the enemy and the victim may often coevolve with each other. [4] How exactly they coevolve depends on many factors, such as population density.
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]
