Scent glands marsupials

In summary we propose that the composition of the scent glands of marsupials may be influenced by their social status, their diet and their individual genetic relationship. For the eastern grey kangaroo we found indications for the influence of social status on the odor profile while in contrast the scent composition in the solitary brushtail possum seemed to be in part determined by dietary effects. The analysis of the scent secretion in the koala indicates that the genetic relationship between individuals determines in part the odor profile produced. 

Furthermore, we predicted from the presence of large external scent glands in two marsupial species that olfactory signals might play a vital role in other marsupials whose olfactory capabilities have not been further investigated. 

Scent Glands and Scent-Marking Behavior in Monotrernes and Marsupials... 

Scent-marking in marsupials. In addition to using specific anal-cloacal, and sternal glands, marsupials use saliva, urine and feces in chemical communication (Eisenberg and Golani, 1977). Other specific glands, such as frontal glands and parts of the body (such as the flank), are also used (Schultze-Westrum, 1965, 1969 Fadem and Cole, 1985).
