Through extensive research on great apes (chimpanzees,                          orangutans, and gorillas), Dr. Nadler has found that several                    aspects of their reproductive behavior, anatomy, and physiology                 are predictable from the amount of competition among males for                  mates.  He hypothesizes that the origins of these differences are               causally related to the difference in their mating systems.                                                                                                     Relatively few species of nonhuman primates live in parental or                 family groups.  Gibbons do so, and the social organization of                   these lesser apes thus differs from that of the great apes.  The                major aim of the present research project is to use the                         monogamous gibbon to test the hypothesis derived from Dr.                       Nadler's research with the polygynous great apes.  Gibbons show                 little or no competition among males for mates, resembling                      gorillas in this way.                                                                                                                                           Pairs of gibbons, the natural social unit, will be studied in                   large enclosures.  The gibbons' behavior will be observed in                    conjunction with anatomical measurements and biochemical assays                 of sex hormones.  Subtle behavioral changes in the female and the               male will be made more detectable by use of different types of                  tests, in which either the male or the female controls physical                 access to the other.                                                                                                                                            Research with gibbons provides a special opportunity to assess                  comparatively the relevance of a monogamous mating system to the                regulation of reproductive behavior in the closest nonhuman                     relatives of human beings.
