Stability of Social Status in Wild Rats: Age and the Role of Settled Dominance

Abstract

One way of understanding the evolution of social dominance is to establish which factors determine an animal's ability to dominate conspecifics. The dynamics of dominance between 20 adult male wild rats were investigated in a multi-generational, free-breeding colony in a large outdoor enclosure. Dominance relations between the adult males were stable and organised in a near-linear hierarchy. Dyadic interactions not fitting the social hierarchy, as well as challenges by subordinates and overt aggression by dominants were rare (< 5%) and principally occurred between animals of similar social rank. The correlates of social status within the colony show, for the first time in adult small mammals, that despite the significant role of body weight on the probability of winning contests, age was the most reliable indicator of adult dominance, with the higher ranking males being older but not necessarily heavier. Age also explained the outcome of 85% of agonistic encounters between dyads, compared with 65% for weights. The proximate mechanisms of age-related dominance fit better the 'previous outcome' hypothesis than the alternative 'fighting skill' or 'site dominance' hypotheses. The stability of dominance relations and the role of age, which in stable groups is equivalent with time spent in the colony, suggest that rats remain dominant over individuals that they have beaten in the past, long after initial body weight asymmetries have disappeared. The functional significance of the acceptance of subordinate social status is consistent with the fact that dominant individuals generally could not monopolize food resources or mates.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
