Protecting the Australian Capsicum industry from incursions of Colletotrichum pathogens
Anthracnose of chili (Capsicum annuum) causes serious production loss globally wherever chili plants are grown especially in the subtropical and tropical regions of Asia and Australia. Anthracnose is caused by a complex ...
Soft drinks, obesity and corporate power: the Australian soft drink industry’s political strategy to position itself as “part of the solution” to obesity
Background Soft drink corporations face scrutiny from governments and public health experts for the contribution of their products to obesity and non-communicable diseases. Historically, the soft drink industry sought to ...
Evaluation of fat, nitrate and 3-nitrooxypropanol for reducing enteric methane emissions from ruminants
Enteric methane produced by ruminants is a dietary inefficiency that contributes to global warming. Feeding diets containing starch to ruminants has been reported to decrease enteric methane emissions. The feeding of methane ...
Identification and characterisation of potential sources of resistance to Ascochyta blight within the exotic germplasm of lentil
Lentil (Lens culinaris Medikus. ssp. culinaris) is high value cool season legume staple food and cash crop, cultivated globally including in Australia. However, the crop is often challenged by biotic and abiotic stresses ...
Microbially mediated nitrogen conservation and loss in low and high nitrogen input rice paddies
High rates of fertilizer nitrogen (N) application in rice paddies is a common practice in the majority of the rice-producing countries. However, more than 60% of the applied fertilizer-N is lost to the atmosphere and other ...
Understanding and mitigating the impacts of major dietary changes on dairy cows
Four experiments were conducted to investigate the effects of major dietary changes on ruminal pH, ruminal fluid composition, eating behaviour, feed intake and milk production of dairy cows. The impacts of both diet ...
Functional aspects of root and leaf development in dryland crop water use under elevated CO2
Atmospheric CO2 concentration ([CO2]) is rising due to anthropogenic activities and is expected to reach ~550 μmol mol-1 by 2050 and exceed ~700 μmol mol-1 by the end of this century. As the main substrate of photosynthesis, ...
Towards sustainable reactive nitrogen management: a multi-dimensional assessment
A multi-dimensional assessment on sustainable reactive nitrogen (Nr) management was conducted. Findings include: (i) the first national assessment of the anthropogenic Nr loss by Australians (47 kg N/capita/year); (ii) the ...
The physiology and functional genomics of the heat stress response in dairy cattle
Thermal stress experienced by dairy cattle, can be one of the greatest limitations on production efficiency and animal health. In the Australian climate the effects of heat stress causes millions of dollars in lost production ...
Genetic variability of zinc utilization in rice (Oryza sativa L.)
Dietary zinc (Zn) deficiency is acute among rice consumers due to low grain Zn concentration ([Zn]) and poor bioavailability. Low grain [Zn] is caused by deficiencies in the soil and plant genetic makeup. Rising atmospheric ...
