Predators and prey interact and coevolve: the predator to catch the prey more effectively, the prey to escape. The coevolution of the two mutually imposes selective pressures . These often lead to an evolutionary arms race between prey and predator, resulting in anti-predator adaptations .
Hosts and parasites exert reciprocal selective pressures on each other, which may lead to rapid reciprocal adaptation.For organisms with short generation times, host–parasite coevolution can be observed in comparatively small time periods, making it possible to study evolutionary change in real-time under both field and laboratory conditions.
For example, exploitative interactions between a predator and prey can result in the extinction of the victim (the prey, in this case), as the predator, by definition, kills the prey, and thus reduces its population. [2] Another effect of these interactions is in the coevolutionary "hot" and "cold spots" put forth by geographic mosaic theory ...
The second experiment focused more on zoonotic pathogens being correlated with emerging infectious diseases in humans. The researchers comprised a database with separate infectious species, infectious pathogens that cause disease in patients with abnormal immune systems, and pathogens that have only been found in one case of human disease.

Mobbing is the harassing of a predator by many prey animals. Mobbing is usually done to protect the young in social colonies. For example, red colobus monkeys exhibit mobbing when threatened by chimpanzees, a common predator. The male red colobus monkeys group together and place themselves between predators and the group's females and juveniles.
By way of example, a parasite that reproduces in an intermediate host may require, as part of their life cycle, that the intermediate host be eaten by a predator at a higher trophic level, and some parasites are capable of altering the behavior of the intermediate host to make such predation more likely; [1] [2] a mechanism that has been called ...
None of these animals belong in space. Aside from sort-of looking like their real-life comparisons they have nothing in common. 3). Tom Nook vs Raccoon
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. [1] The entomologist E. O. Wilson characterised parasites as "predators that eat prey in units of less than one". [2]
