title: A role for the hamster's flank gland in heterosexual communication.
abstract: It is commonly assumed that the male hamsters' flank glands subserve an agonistic role with other males as the intended recipients of the olfactory message. Because of little evidence to support such a relationship, two studies investigated whether females might selectively respond to male flank odors. In a free choice situation females spent more time in proximity with glandular rubbings obtained from intact males than those obtained from castrates or a clean control. Moreover, these sexually receptive females remained longer near odors from familiar as opposed to novel males. The second experiment demonstrated that receptive females spent more time in proximity with flank odors of dominant males as opposed to their subordinate partners or to a clean control. Females can use flank gland odors to discriminate among males as a function of their hormonal state, familiarity and dominance. If this occurs in the wild, such odors could provide cues which would facilitate intersexual selection.
