UV-Green Iridescence Predicts Male Quality during Jumping Spider Contests
Animal colour signals used in intraspecies communications can generally be attributed to a composite effect of structural and pigmentary colours. Notably, the functional role of iridescent coloration that is 'purely' structural (i.e., absence of pigments) is poorly understood. Recent studies reveal that iridescent colorations can reliably indicate individual quality, but evidence of iridescence...
متن کاملDelayed song maturation and territorial aggression in a songbird.
Asymmetries in competitive ability can determine the outcome of social interactions in animals and are often expressed through differences in sexual traits. Competitive ability (resource holding potential, RHP), trait expression and ultimately reproductive success may vary with an individual's age or experience. In some species, reproductively mature males delay acquisition of some adult traits...
متن کاملThe importance of being gravid: egg load and contest outcome in a parasitoid wasp.
Owners have often been found to have an advantage in animal contests. One explanation of this is that the resource under dispute is of greater value to the owner than to the intruder (nonowner). Such 'resource value asymmetries' may be caused by intrinsic factors, such as the physiological state of the contestants. Females of the bethylid wasp Goniozus nephantidis fight for possession of paraly...
متن کاملFight tactics in wood ants: individuals in smaller groups fight harder but die faster.
When social animals engage in inter-group contests, the outcome is determined by group sizes and individual masses, which together determine group resource-holding potential ('group RHP'). Individuals that perceive themselves as being in a group with high RHP may receive a motivational increase and increase their aggression levels. Alternatively, individuals in lower RHP groups may increase the...
متن کاملAssessment strategies and fighting patterns in animal contests: a role for serotonin?
Accurate assessment of the probability of success in an aggressive confrontation with a conspecific is critical to the survival and fitness of the individuals. Various game theory models have examined these assessment strategies under the assumption that contests should favor the animal with the greater resource-holding potential (RHP), body size typically being the proxy. Mutual assessment ass...
