Article
Full-text available
Emerging evidence indicates that dragons can no longer be dismissed as creatures of legend and fantasy, and that anthropogenic effects on the world’s climate may inadvertently be paving the way for the resurgence of these beasts.
Article
Full-text available
Humans create vast quantities of wastewater through inefficiencies and poor management of water systems. The wasting of water poses sustainability challenges, depletes energy reserves, and undermines human water security and ecosystem health. Here we review emerging approaches for reusing wastewater and minimizing its generation. These complementar...
Article
Full-text available
There is a bewildering range of estimates for the number of arthropods on Earth. Several measures are based on extrapolation from species specialized to tropical rain forest, each using specific assumptions and justifications. These approaches have not provided any sound measure of uncertainty associated with richness estimates. We present two mode...
Article
Full-text available
Background While agriculture has taken much environmental water in Australia’s Murray-Darling Basin, agricultural expansion has resulted in a vast number of farm dams, almost three-quarters of a million in the Murray-Darling Basin alone. Methods Over a summer we studied (1) waterbird abundance and species richness and (2) the influence of biophysic...
Article
Full-text available
Physical and financial access impacts food choice and consumption, while educational attainment, employment, income, gender, and socioeconomic status are also influential. Within this context, the aim of the paper is to examine the association between various foods consumed and eating patterns of children between low and higher income households. A...
Article
The Intergovernmental Panel on Climate Change (IPCC) reported that all carbon dioxide (CO2) emissions generated by water resource recovery facilities (WRRFs) during treatment are modern, based on available literature. Therefore, such emissions were omitted from IPCC's greenhouse gas (GHG) accounting procedures. However, a fraction of wastewater's c...
Article
History can complement the scientific disciplines in teaching us about the nature of suicide. The death of Socrates, especially as described by Xenophon, suggests fear of the frailties of old age as a motive for suicide. A Platonic view implies heroism and martyrdom. Cleopatra's death and Kurt Cobain's signify the importance of losing when the stak...
Article
The word however is an adverb and an adverb alone. The current online Oxford (Oxford English Dictionary Online, n.d.) and Cambridge (Cambridge English Dictionary Online, n.d. a) English dictionaries both have it listed solely as an adverb for British English. At the risk of awakening yet another descriptivist versus prescriptivist war, it must howe...
Article
Full-text available
A methodology is investigated for assessment of feeding preferences of grazing sheep where satellite tracking is carried out using GPS collar units. Sheep grazing preferences were analysed by a statistically based approach under constraints of spatial error in the GPS tracking data. The statistical significance of grazing locations was determined b...
Article
Waterborne parasites that infect both humans and animals are common causes of diarrhoeal illness, but the relative importance of transmission between humans and animals and vice versa remains poorly understood. Transmission of infection from animals to humans via environmental reservoirs, such as water sources, has attracted attention as a potentia...
Article
Full-text available
For stormwater harvesting to achieve its full potential in mitigating water scarcity problems and restoring stream health, it is necessary to evaluate the human and environmental health risks and benefits associated with it. Stormwater harbors large amounts of pollutants and has traditionally been viewed as a leading cause of water-quality degradat...
Article
Full-text available
Significance Many suggest we are approaching a sixth mass extinction event, and yet estimates of how many species exist, and thus how many might become extinct, vary by as much as an order of magnitude. There are few statistically robust methods to estimate global species richness, and here we introduce several new methods, including one that build...
Article
Full-text available
Water shortages brought on by the Millennium Drought in Southeast Australia forced greater Melbourne, a city of 4.3 million people, to find innovative ways of increasing water supply and decreasing water demand. This article explores how water managers in Melbourne reacted to the crisis and evaluates the short-and long-term impacts of their decisio...
Article
Full-text available
In Australia, interest in wastewater reuse has grown. While wastewater can potentially offer a nutrient advantage over conventional irrigation, crop yield increases may be offset by effects of high salinity. Effects of wastewater irrigation on crop production and soil health were investigated in two ways: a field experiment addressing short-term ef...
Article
The cocoa pod borer, Conopomorpha cramerella (Snellen) (Gracillariidae: Gracillariinae), is an important pest of cocoa in Southeast Asia and Oceania, with devastating effects on yields. Using data on cocoa pod borer (CPB) infestation and cocoa yield from mixed-variety plantations in South Sulawesi, Indonesia, we developed models for estimating yiel...
Article
Full-text available
The significance of waste-stabilisation ponds (WSPs) to waterbirds has been well documented, but WSP differ depending on their place and purpose in the sewage-treatment system, and there is little information on how birds use these different types of pond. In mid-winter (July) 2012, waterbirds were counted on WSP at 18 sewage-treatment plants in th...
Article
Many farmers in water-scarce regions of developing countries use wastewater to irrigate vegetables and other agricultural crops, a practice that may expand with climate change. There are a number of health risks associated with wastewater irrigation for human food crops, particularly with surface irrigation techniques common in the developing world...
Article
Full-text available
Iwao’s mean crowding-mean density relation can be treated both as a linear function describing the biological characteristics of a species at a population level, or a regression model fitted to empirical data (Iwao’s patchiness regression). In this latter form its parameters are commonly used to construct sampling plans for insect pests, which are...
Article
Full-text available
Wastewater can be an important resource for water-scarce regions of the world, but a major barrier to its use is the associated health risk. Quantitative microbial risk assessment (QMRA) is a probabilistic modeling technique used to determine the health risks from wastewater reuse, but only a handful of QMRA studies have examined the norovirus heal...
Conference Paper
Full-text available
___________________________________________________________________________________________________________ Previous research has investigated the effects of different production, processing and cooking factors on eating quality of Australian pork (Channon and Warner, 2011). However, few studies have reported these effects on different muscles, pre...
Conference Paper
Full-text available
___________________________________________________________________________________________________________ It is well known that the administration of the boar taint vaccine can effectively reduce androstenone and skatole concentrations to minimise risks associated with boar taint and increase intramuscular fat levels (D'Souza et al., 2000), as we...
Conference Paper
Full-text available
___________________________________________________________________________________________________________ Improving the positioning of Australian pork through differentiation on an eating quality basis is required to both maintain and develop our markets. It is not known whether dietary composition and slaughter age typical of pigs in North Ameri...
Article
Full-text available
Site occupancy, as estimated by the probability of presence, is used for monitoring species populations. However, the detection of species at individual sites is often subject to errors. In order to accurately estimate occupancy we must simultaneously account for imperfect detectability by estimating the probability of detection. The problem with e...
Conference Paper
Full-text available
This study involved 60 pigs of three sexes (entire male, female, surgical castrates; n=20 per sex). Three primal cuts were evaluated (loin, silverside and shoulder) and three cooking methods (roast, stir fry (all primals) and grilling as steaks (loin only)). Each cut was either aged for 2 or 7 days (d) post-slaughter and cooked to either a 70 or 75...
Chapter
Full-text available
In the early 1980s, new discoveries suggested the tropical rainforest canopy was the ‘last biotic frontier’ and was believed to be home for many millions of undescribed species. It was thought that 30 million species or more tropical forest arthropods, mostly residing in the canopy, might exist. New estimates for all species on Earth, including ins...
Article
Full-text available
With the loss of natural wetlands, artificial wetlands are becoming increasingly important as habitat for waterbirds. We investigated the relationships between waterbirds and various biophysical parameters on artificial wetlands in an Australian urban valley. The densities (birds per hectare) of several species were correlated (mostly positively) w...
Article
Australia's Millennium Drought transformed how Melbourne, a city of 4 million people, secures and uses its water resources. By thriving in the face of drought, Melbourne's example provides valuable lessons for other major metropolitan areas around the world-in particular, those located in the southwest region of the U.S.-that face long-term reducti...
Article
Full-text available
Urban agriculture is receiving increasing attention throughout the developing world, but debate rages as to whether it is a blessing or a curse. Some see it as savior for the poor, providing food and livelihoods, yet to others it is responsible for harboring and vectoring pathogenic diseases and is an archaic practice that has no place along the pa...
Article
Full-text available
Food production in cities has long been a tradition in many countries around the world and a mainstream activity for many developed countries. While urban agriculture plays an important role in increasing food security and social well-being, it comes with significant costs and constraints. Here, we review the growth of urban agriculture throughout...
Article
Full-text available
Surveillance data suggest that human papillomavirus (HPV) vaccination in Australia is reducing the incidence of genital warts. However, existing surveillance measures do not assess the proportion of the remaining cases of warts that are caused by HPV types other than 6 or 11, against which the vaccine has no demonstrated effectiveness. Using comput...
Article
Full-text available
Understanding the roles of different types of natural and artificial wetlands in providing habitat for waterbirds is crucial to active interventions to conserve wetland biodiversity. This study made use of a large database compiled over 22 years from the ‘Summer Waterfowl Count’ to determine the relative use of five wetland types by 18 species of w...
Article
Full-text available
In 2008, vegetable growers observed stunted lettuce plants showing signs of chlorosis and wilting. It was suspected that monochloramine in the recycled water used for irrigation, in combination with extreme environmental conditions (high irrigation water salinity and extreme heat), was responsible for these crop failures. A series of glasshouse stu...
Article
The reuse of domestic greywater has become common in Australia, especially during periods of extreme drought. Greywater is typically used in a raw, untreated form, primarily for landscape irrigation, but more than a quarter of greywater users irrigate vegetable gardens with the water, despite government advice against this practice. Greywater can b...

Conference Paper
Full-text available
Introduction A model for predicting pork eating quality, using a pathways approach, is being developed using meta- regression statistical techniques and data from previously published studies. For this system to be cuts-based, additional data are required to understand the effects of, and interactions between, different cut types, cooking methods,...
Article
Full-text available
A key challenge in the estimation of tropical arthropod species richness is the appropriate management of the large uncertainties associated with any model. Such uncertainties had largely been ignored until recently, when we attempted to account for uncertainty associated with model variables, using Monte Carlo analysis. This model is restricted by...
Article
Full-text available
Background Surveillance designed to detect changes in the type-specific distribution of HPV in cervical intraepithelial neoplasia grade 3 (CIN-3) is necessary to evaluate the effectiveness of the Australian vaccination programme on cancer causing HPV types. This paper develops a protocol that eliminates the need to calculate required sample size; s...
Article
A monitoring program was undertaken to assess the microbial quality of greywater collected from 93 typical households in Melbourne, Australia. A total of 185 samples, comprising 75 washing machine wash, 74 washing machine rinse and 36 bathroom samples were analysed for the faecal indicator Escherichia coli. Of these, 104 were also analysed for gene...
Article
Deuterium δD isotopic analysis is increasingly being used to trace wildlife movement, and undoubtedly has much to offer in this respect, but questions still remain as to the feasibility and practicality of the method in ecology. Here we report our attempt to determine the geographic origin of an auxiliary hoverfly, Episyrphus balteatus, in south-we...

Conference Paper
Full-text available
Tenderness, juiciness and flavour are the key eating quality attributes that influence consumer appreciation of pork, but there is no simple 'on-line', low cost tool available to industry to grade carcases for these traits. Previous research has determined and documented the importance of a number of pre-and post-slaughter management factors on the...

Article
Full-text available
Reclamation of wastewater for irrigation has had an important role to play in Melbourne’s struggle to manage water resources as effectively as possible. Rapid growth within the first few years of the founding of the city led to a sanitary crisis, which provided the impetus for the construction of a large sewerage system. Interest in using the efflu...
Conference Paper
Full-text available
Conopomorpha cramerella is native to southeast Asia. From the historical record, it appears that one or more populations of this species expanded or altered their host range to include cocoa in north Sulawesi in the 1840s, when it apparently evolved into the cocoa pod borer. There is evidence that only one of three forms of the insect, based on win...
Article
For risk analysis of reclaimed water, current animal and toxicity testing may not detect subtle effects such as interactions that could contribute to complex diseases such as cancers that develop over a long period of time. There is a need for assays that can be validated against known human physiological processes. We have previously validated sen...
Article
Full-text available
1. With the global loss of natural wetlands, waterbirds have become increasingly dependent on alternative and artificial habitats, but the use of such wetlands by waterbirds is typically opportunistic and little consideration has been given to the potential implications for water treatment or waterbird conservation objectives. 2. Wastewater treatme...
Article
Full-text available
Water scarcity in Australia has become a significant challenge for all water users and water reuse is now a critical component of Melbourne’s response to this water crisis, particularly for food production. While most vegetable production occurs in a large-scale commercial environment, there is a significant proportion produced in backyards. With t...
Article
Four estimators of annual infection probability were compared pertinent to Quantitative Microbial Risk Analysis (QMRA). A stochastic model, the Gold Standard, was used as the benchmark. It is a product of independent daily infection probabilities which in turn are based on daily doses. An alternative and commonly-used estimator, here referred to as...
