Agonistic behaviour is a result of evolution, [5] and this can be studied in a number of species facing different environmental pressures. Though agonistic behaviours can be directly observed and studied in a laboratory setting, it is also important to understand these behaviours in a natural setting to fully comprehend how they have evolved and therefore differ under different selective ...
Agonistic competition spans back as far as 300 million years, and thus is deeply ingrained into the genome. [1] Extensive observational evidence of reptiles and birds reveal that when they compete for breeding territory, individuals engage in a specific manner of interactional display, known as ritualistic agonistic behavior (RAB). [ 10 ]
Aggression refers to agonistic behaviors characterized by threats and physical force. Methods of aggression in fish vary widely by species, but some common examples are chasing, charging, biting, fin display, color changes, and flared gills. [1]
Agonistic displays are ritualized sequences of actions, produced by animals belonging to almost all biological taxa, in response to conflict with other organisms. [ 6 ] [ 2 ] [ 1 ] If challenged or threatened, animals may employ a suite of adaptive behaviours, which are used to reinforce the chances of their own survival.
The agonistic tradition to democracy is often referred to as agonistic pluralism. A related political concept is that of countervailing power . Beyond the realm of the political, agonistic frameworks have similarly been utilized in broader cultural critiques of hegemony and domination, as well as in literary and science fiction.
Intraspecific agonistic behavior that results in the death of a combatant is rare because of the associated risk of death or injury. However, agonistic behavior that turns dangerous does occur. In some species, physical traits that are sexually selected for in male courtship displays may also be used in agonistic behavior between two males for ...
In ethology, territory is the sociographical area that an animal consistently defends against conspecific competition (or, occasionally, against animals of other species) using agonistic behaviors or (less commonly) real physical aggression.
Oscar cichlids (Astronotus ocellatus) are able to rapidly alter their colouration, a trait which facilitates ritualised territorial and combat behaviours amongst conspecifics. [4] Individuals of another cichlid species, the blunthead cichlid ( Tropheus moorii ), defend their feeding territory with a display, quivering the tail and fins to ...
