Abstract:
Abstract 10.1002/zoo.1430120205.abs Social interactions of adult female sable antelope, Hippotragus niger, were observed at the National Zoological Park’s Conservation and Research Center. Aggressive behavior was quantified for two herds containing 8 and 11 females. Aggression was lowest at calving, and highest near the time of conception. Dominance hierarchies were strictly linear and stable over time. Dominance rank was highly correlated with age, with the oldest females achieving highest rank. High-ranking females initiated more aggression and were more likely to behave aggressively towards a newly introduced adult female. The newly introduced individual was the victim of prolonged, intense group chases and was permanently excluded from the herd. Low-ranking females directed more aggression at yearling herd members than did high-ranking females. Temporary absences by herd members resulted in long-lasting, substantial increases in received aggression upon their return. Because of their aggressive nature, sable antelope present a challenge to captive management. © 1993 Wiley-Liss, Inc.
