I'm a CSU scientist
12 March 2013
Charles Sturt University (CSU) scientist Dr Rebecca Doyle is doing her bit to encourage young people to study and pursue a career in science. Dr Doyle, from the School of Animal and Veterinary Sciences at CSU in Wagga Wagga, will take part in the I'm a Scientist, Get me out of Here! program over the next two weeks. Over 1600 students from Years 5 to 12, will chat to 15 Australian scientists, including Dr Doyle - deciding along the way which ones should be evicted, and which scientist will be left standing to win a $1000 prize. Up until Friday 22 March, the students will use blogs and instant messaging to meet and chat with the scientists. They’ll have an opportunity to ask scientists questions about their careers, their interests and general science topics. The scientists will be evicted one by one. Program co-producer, Dr Kristin Alford, said the competition, originally conceived in the United Kingdom, is now in its fourth year in Australia. Dr Doyle is a researcher and lecturer in animal physiology and welfare.
Study tracks beef measles outbreak
7 March 2013
A livestock feed supplement contaminated with human faeces is being blamed for an outbreak of parasite infection in a cattle feedlot in northwest NSW.
In a study reported for the first-time in the Australian Veterinary Journal, researchers investigated the origins of cystic lesions found in cattle during routine meat inspections at abattoirs in NSW and Queensland in 2010.
DNA tests showed the lesions to be caused by a human parasite, a tapeworm called the beef tapeworm or Taenia saginata. The infection in cattle by the larval stage of this parasite is also commonly known as beef measles.
The researchers, including Graham Centre member Dr David Jenkins from the School of Animal and Veterinary Sciences at CSU in Wagga Wagga, investigated the outbreak at the feedlot. The investigation indicated the use of the feed supplement copra meal imported from Papua New Guinea was the source of the outbreak. Read full story here.

Analysis of bioactive compounds in canola oil
4 March 2013
Bioactive compounds can have significant health benefits when canola oil is used for human consumption. They also influence shelf-life of the oil. The main bioactive compounds in canola oil are tocopherols (vitamin E), carotenoids, and sterols. Trace metals (e.g. iron and copper) are important as they can catalyse chemical reactions, causing oxidation and deterioration of the oil.
A Graham Centre New Initative project is looking to develop novel methods for the analysis of bioactive compounds in canola oil. Honours student, Ms Clare Flakelar, received a Graham Centre Summer Scholarship in 2012 to begin this work for tocopherols and carotenoids, and the initial results were very promising. Clare has now received a Student Scholarship from GRDC to provide additional support for her Honours research.
A survey of new and existing canola genotypes for trace metals and bioactive compounds, using samples from both commercial deliveries (collected in 2011 and 2012) and genetically-diverse pre-breeding germplasm will be undertaken.
The first stage of the project will be to develop a rapid method for measuring sterols by LC-MS. Following this, oils will be screened for trace metals using AA and/or ICP spectroscopy. To conduct the oxidative stability trial, a new, rapid method for determining oil oxidation using fluorimetry will be developed.
The novel analytical techniques targeted in this project will be necessary for the rapid analysis of oil quality on large numbers of samples if the traits are to be attractive for incorporation into breeding programs and hence new canola varieties.
International arthropod taxonomist shares her expertise
26 February 2013
Josie (JO) Lynn Catindig, an arthropod taxonomist from the International Rice Research Institute (IRRI) in the Philippines, visited the molecular biology laboratory at the Wagga Wagga Agricultural Institute for three weeks during February, to learn the rudiments of DNA barcoding analysis from Dr David Gopurenko (Research Scientist, Molecular Systematics), and to participate in a recent devised project using DNA barcoding to identify cryptic species diversity among agriculturally important parasitoid wasps.
This project is funded by the Graham Centre, as part of the Centre's 2013 New Initiative grant scheme.
During her stay, JO and Dr Gopurenko completed the initial stages of the project, cataloguing and extracting DNA from approximately 700 wasp specimens, in preparation for downstream DNA barcoding. The specimens include a wide variety of important parasitoid wasps sampled from diverse areas. These wasps parasitise agriculturally important arthropod pests by laying eggs into them; in effect, the wasps act as naturally available pest-biocontrols, suppressing and regulating outbreaks of pest insects where they co-occur in agricultural zones.
The alpha taxonomy of these wasps are often poorly understood. DNA barcoding provides a reliable means to rapidly identify alpha taxonomic diversity among wasps, and is being used to identify the species diversity among important wasp biocontrols, and help untangle the complex relationships among the wasp species and their targeted pest hosts.
For more information about this project please contact Dr David Gopurenko.

New research tool to investigate calf deaths
15 February 2013
Charles Sturt University (CSU) is developing a new research tool to help thenorthern Australian beef industry understand more about the timing and causes of calf deaths.
A team led by Associate Professor Scott Norman from CSU’s School of Animal and Veterinary Sciences and the Graham Centre is refining technology that will tell researchers when a cow has had a calf in a remote location to allow them to check on the birth.
Professor Norman said the large scale and remote nature of many northern Australia beef operations means there’s little information about the extent of losses during calving. Read more about this latest research.

Boosting knowledge to enable practice change
31 January 2013
Improved stubble management is possible using a range of techniques. The optimal combination of stubble techniques depends on local conditions, landholder knowledge, preferences and equipment.
“The broader practical application of stubble management techniques into farming systems must involve land managers and be profitable. The effectiveness and benefit and costs of techniques will identify the optimal combination on-ground at the regional level,” explained Graham Centre Director Professor Lemerle.

Commercial herbicide resistance testing has evolved over time
23 January 2013
Herbicide resistance in broad-acre cropping is a major issue confronting farmers today. Knowledge of the herbicide resistance status of a paddock allows for strategic farm planning and correct herbicide choice. As resistance increases, more farmers are electing to have their paddocks tested for herbicide resistance using herbicide resistance testing facilities.
Charles Sturt University has operated a commercial herbicide resistance testing service since 1991 and clients can select either specific herbicides for testing, or since 1995, a standard cross resistance test.
Graham Centre member and PhD student John Broster will present a paper on the use of commercial herbicide resistance testing and the findings from the CSU testing service at the Global Herbicide Resistance Challenge International Conference being held in Perth, Western Australia 18-22 February, 2013.
Using stealth to combat weed invasion
23 January 2013
Unmanned aerial vehicles are often associated with the military but new research at Charles Sturt University (CSU) shows their increasing importance in civilian life.
