    Abstract:
    Since it is thought that flank marking communicates dominance status, experiments were designed to look at changes in aggression and flank marking behaviors in pairs of male hamsters with intact flank glands (Experiment One) or when one (Experiment Two) or both (Experiment Three) members of a pair had their flank glands surgically removed. In Experiment One the dominant members of twelve pairs of hamsters had a mean daily frequency of flank marks that was over two-fold greater than their subordinate partners, F(1,11) = 17.59, p less than 0.001. Over the course of five consecutive daily tests there was a significant decrease in the aggression index of both the dominant, t(44) = 4.49, p less than 0.01, and subordinate, t(44) = 3.33, p less than 0.01, hamsters. Accompanying the decrease in aggression was a significant increase in the flank marking of both dominant, t(44) = 7.8, p less than 0.01, and subordinate, t(44) = 3.59, p less than 0.01, hamsters. In Experiment Two, six out of eleven flank glandectomized hamsters were dominant over their sham operated partners while the remaining five were subordinate. Unlike Experiment One there was no significant difference in the flank marking between dominant and subordinate hamsters, in fact, in seven pairs the subordinate hamsters flank marked more than their dominant partners. In Experiment Three both hamsters had their flank glands removed, and as in Experiment Two, there was no significant difference in flank marking between dominant and subordinate hamsters, neither was there any significant change in their aggression and flank marking behaviors over the course of the five test periods.(ABSTRACT TRUNCATED AT 250 WORDS)
