Life-span studies of dominance and aggression in established colonies of laboratory rats
Abstract
Six mixed-sex colonies of Long-Evans rats were observed at 100-day intervals from colony formation at 100 days of age until all colony members died. Long-term stable dominance relations were observed among males in four colonies while two colonies which had low initial levels of aggression continued to show low intracolony conflict at all ages and no clear dominance relationships. Agonistic interactions among females and between males and females were relatively infrequent and no dominance hierarchy among females was apparent. The aggression of resident males toward intruders increased from 201-601 days of age, but declined overall at age 701. Nevertheless, older males which fought intruders did so as readily as they had when they were young and the few animals that reached 800 days of age continued to attack intruders. Although no systematic decline in total duration or intensity of offense was found across age, there was some evidence of impaired motor performance by older males.

“This can be simulated in the laboratory using a visible burrow system, a semi-naturalistic enclosure that replicates many of the challenges and opportunities of group-living in nature; in this setting, rats rapidly form stable dominance hierarchies (Fig. 3) (Blanchard et al., 1995, Blanchard et al., 1988, Opendak et al., 2016).”

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.
