What's on: AMRI Seminar Series
The Australian Museum Research Institute hosts a monthly series of short talks showcasing current research at the Australian Museum.
- Event Type:
- Special event
- 01.00 PM to 02.00 PM
Each seminar consists of two 30-minute snapshots of new results or ongoing projects designed to keep our staff informed, but are also open to members of the public with an interest in scientific research.
Dung, Dorpers & Diets
Dr Andrew Mitchell, Australian Museum Research Institute
About three-quarters of Australia’s area is rangeland. It contains a wealth of biodiversity including more than 1800 plant 600 vertebrate species. This land must be managed for a complex mix of interests, including of course agricultural production and conservation.
One recent example has been the introduction of more a drought-tolerant breed of sheep, the Dorper, to western NSW. As part of a larger project investigating best management practices for Dorpers on rangelands, we compared the diets of Dorpers, Merinos and goats using a “DNA metabarcoding” approach, i.e. using next generation DNA sequencing methods to identify plant species in dung samples.
Shining Light on History: The Role of Vibrational Spectroscopy
Dr Elizabeth Carter, Vibrational Spectroscopy Core Facility, University of Sydney
Vibrational spectroscopy, which includes the infrared (IR) and Raman analytical techniques, is making significant contributions to our understanding of historical events through revealing the molecular composition and structure of a wide range of materials. The new portability of instruments also means that analyses can be made in situ with minimal disruption to the sample: e.g., in the field, museum or even sitting on scaffolding while identifying pigments used in frescos on the ceilings of cathedrals.
Two recent studies testing for mistleberries in an ancient burial in the UK and dyes used in a 17th century bodice from Spain illustrate the potential of these techniques for research on cultural artifacts and natural history specimens at the Australian Museum.
