Kangaroo, grey

The western grey kangaroo (Macropusfuliginosus), the major indigenous herbivore in southwestern Australia, avoids plants of the family Myrtaceae (which include Eucalyptus spp. cloves, and guava), which includes 3500 species on that continent. Essential oils characterize the Myrtaceae many species contain two to nine of these. In one experiment, seven Myrtaceae species were not browsed, while comparable species of other families were. All seven species contained the monoterpene 2,5-dimethyl-3-methylene 1,5-heptadine. The kangaroos also browsed one non-Myrtaceae species (Sollya heterophylla, Pittosporaceae) very little. This species contained the same monoterpene (Jones etal, 2003). 

It is essential that further work be done on the isoladon and charac-terizadon of echidna and platypus (monotreme) proteins as well as those of the grey and red kangaroos (marsupials), in order to resolve the issues discussed in Section X. The above remarks on purification are particularly pertinent to such studies. 

OLFACTORY COMMUNICATION IN AUSTRALIAN MARSUPIALS WITH PARTICULAR REFERENCE TO BRUSHTAIL POSSUM, KOALA, AND EASTERN GREY KANGAROO... 

The population that we sampled in our study was somewhat special as all animals lived on the secure grounds around Government House in Canberra under controlled conditions. In 1983, 12 eastern grey kangaroos were introduced to this area and because the...

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.
