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 ...
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 behaviors amongst animals for resources have been studied by many researchers, and specifically the interaction of weapons during these exchanges of behavior. [1] Not only the presence of weaponry, but also specific characteristics of the weaponry itself can have an effect on the outcome of competition in determining the winners and ...
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.
Agonism (from Greek ἀγών agōn 'struggle') is a political and social theory that emphasizes the potentially positive aspects of certain forms of conflict. It accepts a permanent place for such conflict in the political sphere, but seeks to show how individuals might accept and channel this conflict positively.
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).

In urban areas, territories can be as small as 5 hectares (12 acres), if they can obtain enough food from bird tables, food waste or artificial feeding in suburban gardens. [4] Spotted hyenas ( Crocuta crocuta ) have highly variable territory sizes, ranging from less than 4,000 hectares (9,900 acres) in the Ngorongoro Crater to over 100,000 ...
The term agonistic behavior is sometimes used to refer to these forms of behavior. Most ethologists believe that aggression confers biological advantages. Aggression may help an animal secure territory, including resources such as food and water. Aggression between males often occurs to secure mating opportunities, and results in selection of ...
