Important aspects of group living include the frequency and type of social interactions (egoistic, cooperative, altruistic, revengeful) between individuals of a group (social life), the group size, and the organization of group members in the group. [citation needed] Terminology of animal groups also varies among different taxonomic groups.
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.
Theoretical framework is focused on the costs and benefits associated with living in groups in terms of the fitness of each individual compared to living solitarily. Living in groups evolved independently multiple times in various taxa and can only occur if its benefits outweigh the costs within an evolutionary timescale. Thus, animals form ...
In the late 1900s, some early research in animal cooperation focused on the benefits of group-living. While living in a group produces costs in the form of increased frequency of predator attacks and greater mating competition, some animals find that the benefits outweigh the costs. Animals that practice group-living often benefit from ...
Eusocial insects like ants and honey bees are multicellular animals that live in colonies with a highly organized social structure. Colonies of some social insects may be deemed superorganisms. [6] Animals, such as humans and rodents, form breeding or nesting colonies, potentially for more successful mating and to better protect offspring.
Most species are social animals, living together in family units or small groups and behaving cooperatively. Typically, only the dominant pair in a group breeds, and a litter of young is reared annually in an underground den. Canids communicate by scent signals and vocalizations. [3]
In opposition to many animal-decision making strategies which encourage individual fitness, group living (or sociality) prioritises an inclusive group fitness. [4] Socioecological factors are thought to influence primate social organisation. For example, the main benefits of group living are hypothesised to be: Improved predator detection.
A collective web of Agelena consociata in Uganda.. A social spider is a spider species whose individuals form relatively long-lasting aggregations.Whereas most spiders are solitary and even aggressive toward other members of their own species, some hundreds of species in several families show a tendency to live in groups, often referred to as colonies.
