Abstract
Olfactory cues can contain information for discrimination of gender that ca n affect subsequent social interactions. Social rodents are hypothesized to use more olfactory cues than nonsocial rodents to distinguish males from f emales. The generality of this hypothesis was tested using the pine vole (M icrotus pinetorum), a social vole. We examined nine possible sources of odo rs. A slide containing an odor from a male and a female was presented to ea ch test subject for 3 min. We recorded the amount of time each test subject spent investigating each odor. Females spent significantly more time inves tigating male urine and male anogenital odors; however, they did nor use an y other odor sources to discriminate gender. In contrast, males did not use any odor sources to discriminate gender. Our results do not support the hy pothesis that all social rodents use numerous odor sources to discriminate gender. Instead, our results are consistent with the alternative hypothesis that use of odor sources to convey information about gender may differ in rodents that live in different microhabitats.
