Abstract:		"The hormonal control of scent marking and related behavior and morphology was examined in female gray short-tailed opossums. Females rarely scent marked when intact or following ovariectomy. Testosterone (T) but not estradiol (E) treatment stimulated chest marking while either hormone stimulated head marking in ovariectomized females tested alone. When the same females were tested with males, T-treated females showed little scent marking of any type; E-treated females showed hip marking in significantly more tests than females in the other treatment groups. Suprasternal scent glands (absent in intact females) and phalluses of females that received T were significantly larger than those of animals that received E or control animals. These findings are discussed with respect to similarities and differences between marsupial and eutherian females and between male and female gray opossums in the hormonal control of sexually dimorphic behavior and morphology"
