Self-organized criticality is an abrupt disturbance in a system resulting from a buildup of events without external stimuli. [4] Examples of pattern types: Abrupt changes in feeding activity. Mechanical grasping of legs forming ant droplets.
Collective animal behavior is the study of how the interactions between individuals of a group give rise to group level patterns and how these patterns have evolved. [5] Examples include the marching of locusts and flocks of migrating birds. Group living however focuses on the long-term social interactions between individuals of a group and how ...
Collective animal behaviour is a form of social behavior involving the coordinated behavior of large groups of similar animals as well as emergent properties of these groups. This can include the costs and benefits of group membership, the transfer of information, decision-making process, locomotion and synchronization of the group.
Lovebirds are well known for mirroring the behaviour of their cage-mates, a form of social facilitation. Social facilitation in animals is when the performance of a behaviour by an animal increases the probability of other animals also engaging in that behaviour or increasing the intensity of the behaviour.
Sociality is the degree to which individuals in an animal population tend to associate in social groups (gregariousness) and form cooperative societies. Sociality is a survival response to evolutionary pressures. [1] For example, when a mother wasp stays near her larvae in the nest, parasites are less likely to eat the larvae. [2]
Individuals may have behavior and morphology modified for group defense, including self-sacrificing behavior. For example, members of the sterile caste of the honeypot ants such as Myrmecocystus fill their abdomens with liquid food until they become immobile and hang from the ceilings of the underground nests, acting as food storage for the ...
Shimmering behaviour of Apis dorsata (giant honeybees). A group of animals fleeing from a predator shows the nature of herd behavior, for example in 1971, in the oft-cited article "Geometry for the Selfish Herd", evolutionary biologist W. D. Hamilton asserted that each individual group member reduces the danger to itself by moving as close as possible to the center of the fleeing group.
Social grooming behavior has been shown to elicit an array of health benefits in a variety of species. For example, group member connection has the potential to mitigate the potentially harmful effects of stressors. In macaques, social grooming has been proven to reduce heart rate. [4]
