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.
Another example is plant self-incompatibility alleles. When two plants share the same incompatibility allele, they are unable to mate. Thus, a plant with a new (and therefore, rare) allele has more success at mating, and its allele spreads quickly through the population. [9] A similar example is the csd alleles of the honey bee. A larva that is ...
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 ...
Disease ecology is a sub-discipline of ecology concerned with the mechanisms, patterns, and effects of host-pathogen interactions, particularly those of infectious diseases. [1] For example, it examines how parasites spread through and influence wildlife populations and communities.
This is an example of divergent evolution. Another hypothesis for mobbing behavior is known as the “attract the mightier hypothesis.” Within this hypothesis, prey species produce a mobbing call in order to attract stronger secondary predator to address the threat of the present primary predator.
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 ...
The 1987 film Predator is an example of prey-reversal where the victim becomes the predator. Armed with a stealth suit and ultimate high-tech gear, the predator methodically dispatches the humans that find themselves in the jungle. The last of his squad, "Dutch" (Arnold Schwarzenegger) must turn from the hunted, into the hunter. [15]
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.
