title: Sexual behavior of the female porcupine Hystrix africaeaustralis.
abstract: Porcupines are sexually active throughout the estrous cycle, and sexual behavior is not affected by the reproductive status and hormonal milieu of females. Increased female-male interactions during estrus are the only indications of behavioral changes during estrus. The lack of aggression shown by females to known males as opposed to aggression shown to strange males, the greater interest shown by males toward certain females, and the superior breeding success of these females suggest a pair-bonding mating system. Limited changes in female receptivity throughout the cycle might be of importance in maintaining the pair-bond.
