Abstract

Testosterone is a steroid hormone with diverse effects on male reproductive function and behavior. The relationship between testosterone and social behavior such as mating and aggression has been investigated in a variety of primate species, but few such studies have been conducted on chimpanzees, and even fewer on primates during the juvenile and adolescent periods. This study explores the relationship between baseline urinary testosterone and behavioral variables including dominance rank, rates of aggression toward peers, and behavioral style in 16 juvenile and adolescent male chimpanzees (Pan troglodytes) living at the New Iberia Research Center in Louisiana. Behavioral observations and urine collection occurred during four research periods, each a year apart. After correcting for the positive association between testosterone and age, testosterone was positively associated with both dominance rank and rates of aggression directed at others. It was negatively associated with rates of aggression received. Individuals scoring highest in the "mellow" behavioral style component showed higher levels of testosterone than individuals scoring lowest in this component, an effect that may be partially due to the confounding effect of rank. The results of this study suggest that hormonal changes during the period preceding adulthood are not simply programmed physiological processes tied primarily to age-related change, but that important age-independent relationships with behavior also exist.

  • Testosterone levels are lower in individuals that are frequent recipients of aggressive behavior, and higher in individuals that are frequent initiators (chimpanzees).

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.
