Conditions under which Male-to-Male Aggression Compromises Cooperation in a Game without Learning
Aggression and cooperation have been the source of many ethology and sociobiology related discussions which have in turn lead to the development of several important models, such as the hawk-dove, cooperator's dilemma and snow-drift games. As these models rarely act in conjunction however, they are considered “separate” means of explaining each phenomenon. Moreover, many of the parameters used ...
متن کاملMale-male aggression renders bottlenose dolphin (Tursiops truncatus) unconscious
Intraspeci c aggression constitutes a signi cant proportion of conspeci c behaviours among many mammal species. Agonistic interactions among male bottlenose dolphins (Tursiops truncatus) have been documented in several diVerent regions, including escalated aggression involving coalitions comprised of several males. However, despite many hours of direct observation most of these encounters ar...
متن کاملOestradiol and human male alcohol-related aggression.
AIMS In comparison to androgens, almost nothing is known about the role of endogenous oestrogens in human aggressive behaviour. This new aspect was studied in the present investigation involving men with a history of alcohol-related aggression (AGG+) and in an age-matched male control population (AGG-). METHODS Male AGG+ volunteers were recruited through advertisements and the controls were d...
متن کاملOctopamine in Male Aggression of Drosophila
BACKGROUND In mammals and humans, noradrenaline is a key modulator of aggression. Octopamine, a closely related biogenic amine, has been proposed to have a similar function in arthropods. However, the effect of octopamine on aggressive behavior is little understood. RESULTS An automated video analysis of aggression in male Drosophila has been developed, rendering aggression accessible to high...
متن کاملProgesterone receptors mediate male aggression toward infants.
Neuroendocrine mechanisms that mediate male aggression toward infants are poorly understood. Although testosterone is known to enhance aggression in other social contexts, evidence that it modulates aggression toward infants is equivocal. We have found that male progesterone receptor knockout (PRKO) mice exhibit no infanticidal behavior and little aggression toward young. Male PRKO mice also di...
