Applied Conservation Management Of A Threatened Forest Dependant Frog, Heleioporus Australiacus, Trent D. Penman, F Lemckert, M J Mahony
Applied Conservation Management Of A Threatened Forest Dependant Frog, Heleioporus Australiacus, Trent D. Penman, F Lemckert, M J Mahony
Faculty of Science - Papers (Archive)
Threatened species management should be based on reliable scientific research. The giant burrowing frog Heleioporus australiacus is a threatened species in south-eastern Australia, and is often recorded on land managed for commercial forestry. As a result, management prescriptions have been developed in the absence of significant research data. Here, we review the available research data and assess the potential for forest management practices to impact upon this species. The species is restricted to naturally vegetated areas, but avoids steep areas, large rivers and forests with high levels of vegetative ground cover. Individuals spend the majority of the year in the …
Trans Fatty Acids Provide Evidence Of Anthropogenic Feeding By Black Bears, Gregory W. Thiemann, Randal S. Stahl, Sharon Baruch-Mordo, Stewart W. Breck
Trans Fatty Acids Provide Evidence Of Anthropogenic Feeding By Black Bears, Gregory W. Thiemann, Randal S. Stahl, Sharon Baruch-Mordo, Stewart W. Breck
Human–Wildlife Interactions
Bears (Ursus spp.) that become conditioned to anthropogenic food sources pose a risk to human safety and generally need to be relocated, rehabilitated, or destroyed. Identifying food-conditioned bears may be difficult if the animal is not captured or killed while immediately engaged in the nuisance behavior. Fatty acid signature analysis has been used to examine the dietary habits of bears and other carnivores and is based on the predictable incorporation of ingested fatty acids into the consumer’s fat stores. Unusual fatty acids that are available in only a few food types may be particularly useful dietary markers. In this …

Applying Seed Germination Studies In Fire Management For Biodiversity Conservation In South-Eastern Australia., Tony D. Auld, Mark K.J Ooi
Faculty of Science - Papers (Archive)
We examine the patterns of germination response to fire in the fire-prone flora of the Sydney basin, south-eastern Australia, using examples from several decades of research. The flora shows a strong response to fire-related germination cues. Most species show an interaction between heat and smoke, a number respond only to heat, whilst a few are likely to respond only to smoke. Many recruit in the first 12 months after fire and show no obvious seasonal patterns of recruitment, whilst several species have a strong seasonal germination requirement, even in this essentially aseasonal rainfall region. Key challenges remaining include designing future …
Management Implications Of Recent Research Into The Effect Of Bitou Bush Invasion, Kristine O. French, Emilie-Jane Ens, Carl Gosper, Elizabeth Lindsay, Tanya J. Mason, Ben Owers, Natalie A. Sullivan
Management Implications Of Recent Research Into The Effect Of Bitou Bush Invasion, Kristine O. French, Emilie-Jane Ens, Carl Gosper, Elizabeth Lindsay, Tanya J. Mason, Ben Owers, Natalie A. Sullivan
Faculty of Science - Papers (Archive)
We review recent research into the impact of bitou bush (Chrysanthemoides monilifera spp. rotundata (DC.) Norl.) on coastal ecosystems which suggest this weed is having widespread impacts on ecosystem services, flora and fauna. Increased decomposition rates and altered nutrient cycling accompany changes in plant community structure and composition. Changes in invaded habitats influence invertebrate and bird assemblages. We summarise research that shows that the establishment phase of seedlings is the key phase where bitou bush outcompetes native species through both resource and interference competition mechanisms.

Gis Data: New Kent County, Virginia Shoreline Inventory Report, Marcia Berman, Harry Berquist, Sharon Killeen, Karinna Nunez, Tamia Rudnicky, Daniel E. Schatt, David Weiss, Karen Reay
Data
The data inventory developed for the Shoreline Inventory is based on a three‑tiered shoreline assessment approach. In most cases this assessment characterizes conditions that can be observed from a small boat navigating along the shoreline. The three tiered shoreline assessment approach divides the shorezone into three regions: 1) the immediate riparian zone, evaluated for land use; 2) the bank, evaluated for height, stability, cover and natural protection; and 3) the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes. Hand-held GPS units are used to log features observed in the field.

Managing Analysis, David Shaw
Australian Information Warfare and Security Conference
The Intelligence profession requires effective management to function properly and professional discourse highlights the changing nature of intelligence work. Highlighted “failures” are linked to organizational structures and ethos, and proposals to address the problems include discussion of human and organizational factors with recommendations that address the issues. However, optimising the intelligence process may not be a simple case of applying management techniques as the work relies substantially on individual endeavour. Innovative management techniques are needed and these should be grounded in recognising the peculiar nature of analysis and the skill set required.

Management Of Invasive Vertebrates In The United States: An Overview, Gary W. Witmer, Patrick W. Burke, Will C. Pitt, Michael L. Avery
Managing Vertebrate Invasive Species
At least 161 introduced/invasive vertebrates have become established in the United States and its territories, including at least 81 mammalian, 94 avian, and 86 reptilian/amphibian species. Particularly problematic species include feral cats and dogs; feral pigs; commensal rats and mice; starlings, pigeons, and house sparrows; and bullfrogs, brown treesnakes, and coqui frogs. We briefly review these introductions and the types of damage they cause. We review the basic types of methods used for control or eradication of each taxonomic group, including physical, chemical, biological, and cultural methods. We also discuss some of the challenges in managing these species, including issues …

The Brown Treesnake Rapid Response Team, James W. Stanford, Gordon H. Rodda
Managing Vertebrate Invasive Species
In the 1940s the brown treesnake (Boiga irregularis) was accidentally transported to Guam and became established. Brown treesnakes have caused and continue to cause major problems for the ecology, economy, and quality of life on Guam. As Guam’s snake densities increased in the late 1970s, extralimital encounters began to be reported on islands with transportation links to Guam. In 1993, a major effort was initiated to reduce the potential for brown treesnakes to accidentally enter Guam’s transportation system. In 2002, a multi-agency Rapid Response Team (RRT) was established to assist in detection and capture of brown treesnakes on …

Developing A Decision Support System For Improving Possum Control Planning, Bruce Warburton, Jim Coleman, Mark Fuglestad, James Dietrich
Managing Vertebrate Invasive Species
Brushtail possums are a major invasive pest in New Zealand. A decision support system (DSS) has been developed to enable those involved in operational planning or delivery of possum control to access available relevant knowledge when making operational decisions. The DSS comprises checklists that ensure users consider relevant constraints and issues, a database of best-practice information on possum control, and an “expert” system that recommends actions based on information provided by the user.

Invasive Species: A National Perspective And The Need For A Coordinated Response, Lori Williams
Managing Vertebrate Invasive Species
The multiple economic, environmental, and animal and human health impacts of invasive species pose complex challenges in policy formation and governmental coordination. The National Invasive Species Council (NISC) was established by an Executive Order in 1999 to provide coordination, planning and facilitate cooperation among the diverse federal agencies and to take a more comprehensive approach to invasive species. NISC, assisted by the nonfederal Invasive Species Advisory Committee (ISAC) has developed several tools and enhanced capacities to address invasive species. Additionally, NISC has helped place greater emphasis on essential prevention, early detection and rapid response, research, public outreach, and international cooperation …

Population Viability Analysis Of Monk Parakeets In The United States And Examination Of Alternative Management Strategies, Stephen Pruett-Jones, James R. Newman, Christian M. Newman, Michael L. Avery, James R. Lindsay
United States Department of Agriculture Wildlife Services: Staff Publications
In the United States, monk parakeets (Myiopsitta monachus) are expanding their geographical distribution, and their overall population size is growing exponentially. Monk parakeets are causing widespread economic damage in the United States by nesting on utility structures, which leads to electrical fires and power outages. Although few life history data are available for the species from North America, extensive data are available from the species’ native range in South America. Incorporating data from South America into the population viability analysis program VORTEX, we simulated population growth in United States monk parakeets to determine whether it is likely that …

Invasive Predators: A Synthesis Of The Past, Present, And Future, William C. Pitt, Gary W. Witmer
United States Department of Agriculture Wildlife Services: Staff Publications
Invasive predators have had devastating effects on species around the world and their effects are increasing. Successful invasive predators typically have a high reproductive rate, short generation times, a generalized diet, and are small or secretive. However, the probability of a successful invasion is also dependent on the qualities of the ecosystem invaded. Ecosystems with a limited assemblage of native species are the most susceptible to invasion provided that habitat and climate are favorable. In addition, the number of invasion opportunities for a species increases the likelihood that the species will successfully establish. The list of routes of entry or …

Evaluating P And K Fertilizer Prescriptions From Site-Specific Technologies, John H. Grove, E. M. Pena-Yewtukhiw
Soil Science News and Views
Developing a field's fertilizer prescription as a part of a site-specific nutrient management plan can be one of the more costly tasks undertaken. Those costs are traditionally associated with gathering of a number of plant and/or soil samples, their testing, as well as acquiring and applying amendments. Soil sample analysis is particularly important for traditional phosphorus (P), potassium (K) and soil acidity (pH) management. Soil sampling requires skill and time, time that may be in short supply when crop harvest is to be soon followed by establishment of a succeeding crop. Soil test results are not always timely, further delaying …
System Architecture And Mobility Management For Mobile Immersive Communications, Mehran Dowlatshahi, Farzad Safaei
System Architecture And Mobility Management For Mobile Immersive Communications, Mehran Dowlatshahi, Farzad Safaei
Faculty of Informatics - Papers (Archive)
We propose a system design for delivery of immersive communications to mobile wireless devices based on a distributed proxy model. It is demonstrated that this architecture addresses key technical challenges for the delivery of these services, that is, constraints on link capacity and power consumption in mobile devices. However, additional complexity is introduced with respect to application layer mobility management. The paper proposes three possible methods for updating proxy assignments in response to mobility management and compares the performance of these methods.

Most environmental lawyers, like ecologists, wish to see broad scale landscape change, better management of land and improved protection of remnant vegetation and threatened species. Incorporating scientific knowledge into effective strategic planning is one step. Implementing strategic planning is another, necessitating the flow of priorities into statutory planning and regulation. The translation of broad landscape scale conservation objectives on to the ground requires not only improved understanding but also active use of the legal system. The law relating to the regulation of land use and vegetation clearing, threatened species conservation and catchment management is complex, inter-dependent and dynamic. While planning …

An Alternative Approach To Coal Mine Site Water Management: A Case Study On West Cliff Colliery, Antony Volcich, Stephen A. Short, Adrian C. Hutton, Robert John Morrison
Faculty of Science - Papers (Archive)
The provision of water supply, its usage and discharge, are major concerns for all mines, often accounting for a significant portion of the daily running costs. To reduce these costs, mines will collect as much site runoff as possible, and recycle the water whenever economically feasible. The constant recycling of on-site waters can mean that, over time, the levels of salinity, acidity or alkalinity, or other contaminants may build up within the internal water management system to a point which may lead to problems with licensed discharge requirements. This project investigated the water quality at West Cliff Colliery, in order …

Water Quality Assessment - Issues From A Laboratory Management Perspective, Robert John Morrison, Mark R. O'Donnell, D. Springer
Faculty of Science - Papers (Archive)
This paper considers issues relating to the measurement of water quality parameters in the laboratory, especially an external (usually commercial) laboratory. Many organisations now use testing laboratories for water quality measurements, a process that has advantages and some limitations. The interaction between the testing laboratory and the organization requiring the data is crucial, and this paper looks at some aspects where a full appreciation of the role of each partner is important. These include limits of detection and reporting, measurement uncertainty, sample storage and preservation times, and various quality control procedures.
Reconciling Self: Gay Men And Lesbians Using Domestic Materiality For Identity Management, Andrew W. Gorman-Murray
Reconciling Self: Gay Men And Lesbians Using Domestic Materiality For Identity Management, Andrew W. Gorman-Murray
Faculty of Science - Papers (Archive)
This paper contributes to research on gay/lesbian experiences, meanings and uses of domestic environments by considering the role of domestic materiality in gay/lesbian identity management. Prior work shows that accumulating and arranging meaningful possessions in domestic space underwrites identity work. Drawing on in-depth interviews with gay/lesbian Australians, I apply this contention to gay/lesbian homemaking practices. In particular, conceptualising identity as fractured, I argue that maintaining domestic materiality reconciles diverse dimensions of multi-faceted selves. Different possessions embody different facets of self – sexuality, familial connections, cultural heritage, spiritual beliefs, inter alia. Juxtaposing these objects at home brings together the diverse fragments …

Embracing Knowledge And Behaviour Management To Improve Performance Of Software Intensive Projects, Ricardo Peculis, Derek Rogers, Peter Campbell
SMART Infrastructure Facility - Papers
Many reasons have been offered to explain why software projects fail. Still, software intensive projects often present schedule delays, cost overruns and delivering products with reduced functionality. This paper argues that lack of knowledge is yet another factor that causes projects to under perform, which in turn drives undesirable social behaviour that worsens the situation. Software intensive projects develop solutions highly dependent on software that should satisfy a need. The engineering process to develop such complex solutions comprises of a series of transformations that transform products from one domain into products in another domain, requiring knowledge pertinent to both input …
