A preliminary experiment was conducted to determine whether common ringtail possums ate different amounts of foliage between individual Eucalyptus polyanthemos, as we had observed with E.
Therefore, having shown in the preliminary experiment that there was an eightfold difference in DMI of common ringtail possums between individual E.
The effect of pure sideroxylonal on DMI of common ringtail possums was measured by adding sideroxylonal to a basal diet of fruits and cereal.
In order to assess the relevance of intraspecific variation in foliar chemistry to the choices made by individual animals, we measured the foliar sideroxylonal concentration and the potential DMI of common ringtail possums in a large number of E.
Calibration equations were developed to estimate sideroxylonal concentration and DMI by common ringtail possums using reference values derived from the HPLC assays and animal experiments, respectively.
The preliminary experiment clearly showed substantial variation in dry matter intake (DMI) of common ringtail possums between individual E.
