Identifying a cane toad

Adult cane toads are usually very large – around 9-15 cm (or 3.5 to 5 inches) long. If you find one over 4 cm long, you should be able to identify it from the picture below. However, smaller toads can easily be confused with native frogs. To make sure you don’t kill a native frog […]

Animal welfare issues associated with marking wild animals for identification

Identification of wildlife aids biological study and conservation management and usually involves the application of an artificial mark. Marking can affect the animals involved through the act of marking itself, the wearing of the mark and the procedures required for observing the mark. Effects on subject animals include alteration of: appearance; behaviour; interactions with their […]

Threatened Species Protection Act

Provides for the protection and management of threatened native flora and fauna. Threatened species are to be listed according to the process set out in the Act. Critical habitats are also to be identified. A strategy for the conservation of threatened species is to be developed which must include proposals for ensuring the survival of […]

Identification of 5 beta -pregnane and 5 beta -androstane derivatives in adrenal venous and peripheral blood plasma of the female possum (Trichosurus vulpecula)

In the possum a marked sex difference has been found in the steroids in adrenal venous plasma. Four 5 beta -pregnane and four 5 alpha ( beta ) androstane derivatives together with ten 4-ene-3-keto steroids were isolated from the adrenal venous plasma of the female and definitively identified by gas chromatography-mass spectrometry. The results confirm […]

Comparison of two methods of faecal analysis of herbivore diet

Two techniques for determining the proportions of different plant species eaten by the brush-tailed opossum (Trichosurus vulpecula) were compared. Both techniques – bacterial degradation and chemical maceration of faeces – produced similar results, and confirmed that a correction factor is needed to allow for the differential loss of cuticle of some plant foods during digestion […]
