Urine marking varies with dominance status; socially dominant male house mice urine mark more than those that are socially subordinate.
We found that dominant females were more likely to breed than subordinates, but that dominance status was not predicted by circulating T. In the second experiment, we allowed a resident male and female to establish ownership of a breeding aviary (territory) then introduced a second, intruder female.
Surprisingly, the initiator's dominance status shows little correlation with successful initiation of departure; more-dominant individuals are no more likely to lead a successful departure than subordinate individuals.
Neither dominance status nor sex influenced public information use.
Does dominance status influence readiness to breed in female juncos?
However, queens have greater relative MB volumes than their workers, and MB development is positively associated with social dominance status in some species.
The use and learning of visual landmarks seem to be strongly influenced by ecological demands and vary according to habitat, sex and, presumably, dominance status.
In many species, males challenged with simulated or real territorial intrusions increase T and levels of aggression, outcomes linked to higher dominance status and greater reproductive success.
Here, we conducted two experiments designed to answer three questions: Are endogenous concentrations of T associated with dominance status in captive female juncos?
The first experiment was designed to show that red knots are capable of using public information, and whether dominance status or sex affected its use.
The number of interior squares with urine marks, and, to a lesser extent, the number of perimeter squares with urine marks, were both significant predictors of aggression scores and social dominance status.
