In the small dasyurid marsupial, Antechinus stuartii, males exhibit scent-marking in the form of cloacal marking of nesting areas during the breeding season. Females of this species show no such behavior. To characterize the potential male pheromonal scent signal, urine-derived volatiles from sexually active males were analyzed by GC-MS and compared to that of females and a castrated male. More than 10 urinary compounds were identified.
A series of homologous methylketones was observed in both males and females, whereas aldehydes were present only in female urine. Urine from the castrate was virtually compound-free except for minute concentrations of a compound tentatively identified as 2,4-dithiapentane. This compound was also found in one of the sexually active males. The GC profiles of the sexually active males contained high concentrations of two pyrazine derivatives and four methylketones that were not detected in the profiles of either females or the castrate. These compounds may influence social communication in the brown antechinus, Antechinus stuartii.
