The model was particularly inspired by the work of Italian physicist Vito Volterra, who had developed his predator-prey equations based on observations of fish populations in the Adriatic Sea during World War I. Volterra's work showed that during the war, when fishing was reduced due to military activities, the proportion of predator fish ...
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.
The selfish herd theory states that individuals within a population attempt to reduce their predation risk by putting other conspecifics between themselves and predators. [1] A key element in the theory is the domain of danger , the area of ground in which every point is nearer to a particular individual than to any other individual.
Predators of primates include various species of carnivorans, birds of prey, reptiles, and other primates. Even gorillas have been recorded as prey. Predators of primates have diverse hunting strategies and as such, primates have evolved several different antipredator adaptations including crypsis, alarm calls and mobbing. Several species have ...
Chemical signals in wolf urine are avoided by their prey [12]. Much of the communication between predators and prey can be defined as signaling. In some animals, the best way to avoid being preyed upon is an advertisement of danger or unpalatability, or aposematism.
Social learning refers to learning that is facilitated by observation of, or interaction with, another animal or its products. [1] Social learning has been observed in a variety of animal taxa, [2] [3] such as insects, [4] fish, [5] birds, [6] reptiles, amphibians [7] and mammals (including primates [8]).
Prey’s hero is Naru (Midthunder), a young Comanche woman in 1719 who yearns to leave the gathering behind and become a hunter — and is the first person in her tribe to suspect they’re being ...
In size-selective predation, predators select prey of a certain size. [81] Large prey may prove troublesome for a predator, while small prey might prove hard to find and in any case provide less of a reward. This has led to a correlation between the size of predators and their prey. Size may also act as a refuge for large prey. For example ...
