Author Chaudhuri, M.; Ginsberg, J.R. doi  openurl
  Title Urinary androgen concentrations and social status in two species of free ranging zebra (Equus burchelli and E. grevyi). Type Journal Article
  Year 1990 Publication Journal of Reproduction and Fertility Abbreviated Journal J Reprod Fert  
  Volume 88 Issue (up) Pages 127-133  
  Keywords zebra; testosterone; androgens; territoriality; social behaviour; dominance  
  Abstract In both species of zebra, breeding males had higher urinary androgen concentrations (ng androgens/mg Cr) than did non-breeding bachelor males (30.0 +/- 5.0 (N = 9) versus 11.4 +/- 2.8, (N = 7) in the plains zebra; 19.0 +/- 2.2 (N = 17) versus 10.7 +/- 1.2 (N = 14) in the Grevy's zebra). In the more stable family structure of the plains zebra (single male non-territorial groups) variations in androgen concentrations could not be ascribed to any measured variable. In the Grevy's zebra, androgen values were significantly lower in samples taken from territorial (breeding) males which had temporarily abandoned their territories (N = 4) and the urinary androgen concentration for a male on his territory was negatively correlated with the time since females last visited the territory.
