Characterization Of Salmonella Serovars By Pcr–Single-Strand Conformation Polymorphism Analysis, S. Nair, Kwai Lin Thong, T. Pang, M. Altwegg Jul 2002

Characterization Of Salmonella Serovars By Pcr–Single-Strand Conformation Polymorphism Analysis, S. Nair, Kwai Lin Thong, T. Pang, M. Altwegg

Research Publications (2000 to 2005)

PCR-restriction fragment length polymorphism (PCR-RFLP) and PCR–single-strand conformation polymorphism (PCR-SSCP) analyses were carried out on the 1.6-kb groEL gene from 41 strains of 10 different Salmonella serovars. Three HaeIII RFLP profiles were recognized, but no discrimination between the serovars could be achieved by this technique. However, PCR-SSCP analysis of the groEL genes of various Salmonella serovars produced 14 SSCP profiles, indicating the potential of this technique to differentiate different Salmonella serovars (interserovar differentiation). Moreover, PCR-SSCP could differentiate strains within a subset of serovars (intraserovar discrimination), as three SSCP profiles were produced for the 11 Salmonella enterica serovar Enteritidis strains, and …

Animal Diet Modification To Decrease The Potential For Nitrogen And Phosphorus Pollution, Terry J. Klopfenstein, Rosalina Angel, Gary Cromwell, Galen E. Erickson, Danny G. Fox, Carl Parsons, Larry D. Satter, Alan L. Sutton, David H. Baker, Austin Lewis, Deanne Meyer

Department of Animal Science: Faculty Publications

In 1996, the Council for Agricultural Science and Technology (CAST) published a report entitled Integrated Animal Waste Management. One of the recommendations in that report was to “change animal diets to decrease nutrient outputs” (CAST 1996, 1). Since that time, concentration of animal production units has continued, public concern about the environmental effects of animal manure has increased, and the Environmental Protection Agency (EPA) has proposed more restrictive requirements for concentrated animal feeding operations (CAFO regulations).

Progress has been made since 1996 to decrease nutrient outputs by animals through diet modification and nutrition. The current study describes the existing …

A Decision Support Gis For The Clean Water Act Permit Review Analysis, Wei (Wayne) Ji, Rima A. Wahab, Jia (Jane) Ma Jul 2002

A Decision Support Gis For The Clean Water Act Permit Review Analysis, Wei (Wayne) Ji, Rima A. Wahab, Jia (Jane) Ma

International Congress on Environmental Modelling and Software

Section 404 of the Clean Water Act is the primary federal statute of the United States that regulates the discharge of dredged or fill materials into lakes, rivers, and wetlands. The Section 404 permit review process involves comprehensive assessments of physical, biological, ecological, and socioeconomic impacts of potential human alterations on aquatic ecosystems across spatial scales. Such assessments require the integration of management decision-making with innovative data handling techniques and assessment methodology. The Section 404-permit process is often hindered by the lack of well-developed scientific information and the technical tools for efficient data analysis. The individual permit review frequently becomes …

A Comparison Of Model Structures For The Simulation Of Amphipod (Talitrus Saltator) Population Dynamics., P. M. Anastácio, S. C. Gonçalves, M. A. Pardal, J. C. Marques

International Congress on Environmental Modelling and Software

A dynamic model is proposed in order to simulate sandhopper (Talitrus saltator) populationdynamics under various scenarios. It was built under the Stella simulation software and so far it has attainedthe calibration and verification stages. The basic structure of the model depends on the simulation of thenumber of animals in each age class (45 days). A von Bertalanffy growth curve has been adjusted to thetreated field data. From this equation another one expressing the instantaneous growth rate was extracted andused to calculate the growth. The number of individuals in each age class increases due to the ageing processi.e. new individuals coming …

A Regional Water Quality Model Designed For A Range Of Users And For Retrofit And Re-Use, R. A. Vertessy, J. M. Rahman, F. G. R. Watson, R. M. Argent, S. M. Cuddy, S. P. Seaton Jul 2002

A Regional Water Quality Model Designed For A Range Of Users And For Retrofit And Re-Use, R. A. Vertessy, J. M. Rahman, F. G. R. Watson, R. M. Argent, S. M. Cuddy, S. P. Seaton

International Congress on Environmental Modelling and Software

We discuss the motivations for, and software design concepts underpinning, the development of a regional water quality model. The Environmental Management Support System (EMSS) was developed to predict daily fluxes of runoff, total suspended sediment, total nitrogen and total phosphorous through a large-scale river network. It was built using a custom environmental modelling framework called Tarsier, founded on the Borland C++ Builder rapid application development environment. Three autonomous models are integrated within the EMSS, but are loosely coupled so that alternative models could be retrofitted into the system if desired. The three models share common data handling and visualisation routines …

Improving The Model Development Cycle By Automatic Configuration Of Modelling Tools, K. De Jong, C. G. Wesseling, D. Karssenberg Jul 2002

Improving The Model Development Cycle By Automatic Configuration Of Modelling Tools, K. De Jong, C. G. Wesseling, D. Karssenberg

International Congress on Environmental Modelling and Software

Model development is a difficult and timely process involving various steps to create, check and improve the model. Typically all kinds of software tools are used to facilitate this process. Central to model development is the model definition and we show that, apart from calculating model results, it can be used to tailor some of the tools used to the model at hand. This speeds up model development and might lead to better models.

Feeding Elk In Greater Yellowstone: A Case Study In Ex-Ante Group Decision Support, Lynne Caughlan, D.L. Hoag Jul 2002

Feeding Elk In Greater Yellowstone: A Case Study In Ex-Ante Group Decision Support, Lynne Caughlan, D.L. Hoag

International Congress on Environmental Modelling and Software

Natural resource management decisions are complicated by multiple property rights, management objectives, and stakeholders with varying degrees of influence over the decision making process. Managers must consider all opinions when they develop management policies. Often this type of information is not understood until after a decision has been made, which can result in wasted time and effort. We developed an institutional framework to predict stakeholders’ influence in the resource management decision-making process before the stakeholder meetings actually occur. Then we applied the framework to an actual case study concerning whether to feed elk over the winter in the Greater Yellowstone …

Parameterizing Gpfarm: An Agricultural Decision Support System For Integrating Science, Economics, Resource Use, And Environmental Impacts, G. S. Mcmaster Jul 2002

Parameterizing Gpfarm: An Agricultural Decision Support System For Integrating Science, Economics, Resource Use, And Environmental Impacts, G. S. Mcmaster

International Congress on Environmental Modelling and Software

Few farmers and ranchers adopt agricultural software such as decision support systems (DSS). While numerous decision aids are available, most are too difficult for producers to use, exclude components (e.g., economic budgeting, weeds, multicriteria decision analysis) necessary for meaningful use on farms and ranches, and usually suffer from poor understanding by scientists of producer needs and how they process information. The USDA-ARS Great Plains Framework for Agricultural Resource Management (GPFARM) decision support system has been developed that integrates a graphical user interface, data from farms and ranches, soil-plant-weed-water-N-erosion simulation modules, an economic analysis package, and a multicriteria decision making (MCDM) …

An Adaptive Framework For Ecological Assessment And Management, David A. Mauriello, Richard A. Park Jul 2002

An Adaptive Framework For Ecological Assessment And Management, David A. Mauriello, Richard A. Park

International Congress on Environmental Modelling and Software

In this paper, we present a conceptual framework for integrating ecological models into a process for management of complex ecological systems. This conceptual framework, that we call Adaptive Ecological Risk Analysis, is an iterative process based upon ecological modeling, the development and implementation of management alternatives, and the evaluation of their effectiveness. Adaptive Ecological Risk Analysis depends heavily on the use of ecological models to perform both prospective and retrospective risk assessments and to analyze the outcomes of alternative management strategies. In order to illustrate the use of Adaptive Ecological Risk Analysis, we use the AQUATOX simulation model to examine …

Environmental Foresight And Structural Change, M. B. Beck Jul 2002

Environmental Foresight And Structural Change, M. B. Beck

International Congress on Environmental Modelling and Software

Policy-makers and the public, it has famously been said [Brooks, 1986], are more interested in the possibility of non-linear dislocations and surprises in the behavior of the environment than in smooth extrapolations of current trends. How indeed should we design our models to generate environmental foresight, to detect, in particular, threats to our environment lying “just beyond the horizon”? In facing this prospect of potentially profound dislocations in behavior, the problem is that the number of state variables in the model, whether they interact, how they interact, and the form of their interactions, may be evolving over time. What may …

Contaminated Industrial Sites, Real-Time Monitoring, Knowledge-Based Systems, Modelling, Knowledge Acquisition, Alexander Komarov, Oleg Chertov, G. Andrienko, N. Andrienko, Alexey Mikhailov, P. Gatalsky

International Congress on Environmental Modelling and Software

Decision support in sustainable forest management (SFM) has some specific features: a) it can perform quantitative prediction of forest ecosystem dynamics under different scenarios of SFM; b) it can spatially combine the predictions of different scenarios on the territory of a forest unit to support decisionmaking. We represent the integration of simulation modelling with the exploratory spatial data analysis (ESDA). The EFIMOD 2 is a spatially explicit individual-based ecosystem model, which was run for simulation of forest ecosystem dynamics at stand level on the territory of a state forest in Central European Russia. The DESCARTES software system designed to support …

Immersive, Interactive Exploration Of Changing Landscapes, Christian Stock, I. D. Bishop

International Congress on Environmental Modelling and Software

It is expected that the structure of rural communities and the visual landscape of the Cudgewa Valley in northeastern Victoria, Australia, will change markedly within the next 20 years. We are creating a portable environment for landscape simulation, using geographic information systems and virtual reality technology. This will allow the community and stakeholders of this valley to propose alternative land cover configurations, move through realistic renderings of the consequent landscape, and review outcomes on a variety of environmental, economic and social scales. A detailed three dimensional visual model of the region will be rendered using OpenGL Performer. People will also …

A Conceptual Model For Integrated Assessment, Markus Knoflacher Jul 2002

A Conceptual Model For Integrated Assessment, Markus Knoflacher

International Congress on Environmental Modelling and Software

The challenge of integrated assessment is the integration of scientific and social aspects for the preparation of decisions. On one hand it is necessary to find scientific and technologically sound solutions, on the other hand the results should meet the interests of social groups affected by the particular project. In large projects it is also necessary to consider the effects on sustainable development. The bandwidth of the different aspects is in practise confronted with problems in acquisition of data, inhomogeneity and incompleteness of information about the actual conditions and the effects of the project. To solve the task in a …

The Socioeconomic Importance Of Eco-Resort Management Practices, Christine Lim Jul 2002

The Socioeconomic Importance Of Eco-Resort Management Practices, Christine Lim

International Congress on Environmental Modelling and Software

In recent years, ecotourism has become an increasingly important alternative form of sustainable tourism. Couran Cove Island Resort, which is located on South Stradbroke Island off the Gold Coast in Queensland, Australia, is an eco-resort on one of the world's few naturally occurring sand islands. As an ecotourism-based resort, Couran Cove is active in implementing a range of initiatives for sustainable management of its environment, which is particularly important as it is home to a wide variety of plant communities. Consequently, the resort has a niche market of ecotourists. This paper examines how Couran Cove Island Resort applies the principles …

Multi-Model Integration In Decision Support System: A Technical User Interface Approach For Watershed And Lake Management Scenarios, David Lam, Luis F. León, Stuart Hamilton, Norm Crookshank, Derek Bonin, David Swayne Jul 2002

Multi-Model Integration In Decision Support System: A Technical User Interface Approach For Watershed And Lake Management Scenarios, David Lam, Luis F. León, Stuart Hamilton, Norm Crookshank, Derek Bonin, David Swayne

International Congress on Environmental Modelling and Software

Computer simulations using mathematical models provide useful tools to investigate different scenarios based on watershed management strategies and environmental conditions. To study the impact of these strategies and conditions, different models must be linked or coupled following hydrological pathways in air, soil and water. To connect one model to another successfully, we need to resolve a number of computational issues such as the compatibility of software tools and the consistency of the temporal and spatial scales and model assumptions used. To keep track of these issues and to provide efficient algorithms to resolve them, we propose to use a technical …

Hoofs - A Multi-Scale, Agent-Based Simulation Framework For Studying The Impact Of Grazing Animals On The Environment, J. A. Beecham, S. P. Oom, C. P. D. Birch

International Congress on Environmental Modelling and Software

An agent based system (HOOFS) has been developed in order to examine the interactions between foraging animals and a spatially explicit description of the environment, including vegetation growth processes. HOOFS makes use of the agent-based approach to develop a model of foraging in which animal decision making processes are explicitly modelled. The model has evolved from one where foraging decisions are based on a simple biased random walk model with an information weighting parameter, through one in which animals decide between direct walking towards an object as against continuous foraging, ending with a model where memory is used. The model …

Some Novel Information Systems For The Empowerment Of A Decision-Making Process On A Territory: Outcomes From A Four Years Participatory Modeling In Senegal, Patrick D’Aquino Jul 2002

Some Novel Information Systems For The Empowerment Of A Decision-Making Process On A Territory: Outcomes From A Four Years Participatory Modeling In Senegal, Patrick D’Aquino

International Congress on Environmental Modelling and Software

The Maps, the Geographical Information Systems (GIS), the Role-Playing Games (RPG) and the other participatory supports, the Multi-agent Systems (MAS): all are modeling supports designed through their conceivers' perception. Even in participatory approaches, these designing and modeling can take off towards technocratic, but often unconscious, drifts. Yet, a true empowerment of local governance means to let stakeholders and their principals totally handle their information and modeling systems. The mere access to information is certainly a first step but it is far from a true power over it, so long as this local people are not able to select, process and …

Graphic Model-Based Software For Supporting The Search For Efficient Environmental Strategies: Method, Real-Life Applications And Future Developments, Alexander V. Lotov Jul 2002

Graphic Model-Based Software For Supporting The Search For Efficient Environmental Strategies: Method, Real-Life Applications And Future Developments, Alexander V. Lotov

International Congress on Environmental Modelling and Software

Application of a new graphic multi-criterion model-based approach to integrated assessment and screening of environmental strategies is described. The approach is based on integration of mathematical models and visualization of the Pareto-efficient (non-dominated) frontier. In the case of linear integrated models, the visualization is based on application of the Interactive Decision Maps (IDM) technique that visualizes the frontier in the form of multiple animated decision maps provided on-line. Interactive visualization of the Pareto-efficient frontier helps the user to understand potentialities of choice and criterion tradeoffs for 3 to 7 criteria. Moreover, the IDM technique supports identification of a preferred non-dominated …

Using Models To Predict Methane Reduction In Pasture- Fed Dairy Cows, C. C. Palliser, S. L. Woodward Jul 2002

Using Models To Predict Methane Reduction In Pasture- Fed Dairy Cows, C. C. Palliser, S. L. Woodward

International Congress on Environmental Modelling and Software

Because New Zealand is a signatory to the Kyoto Protocol Framework Convention on ClimateChange (1997), it is required to report national greenhouse gas emissions and maintain them at 1990 levelsby 2008-2012. New Zealand has one of the highest per capita levels of the greenhouse gas methane[Woodward et al., 2001] and most of this arises from gut fermentation from ruminants. Not only does thisruminant-produced methane contribute to greenhouse gas emissions, but it is also wasteful in terms ofenergy loss for the animal. This paper investigates the ability of four methane models within MOLLY[Baldwin, 1995] to model the methane production from a …

Evaluating Management Strategies In Paraguacu River Basin By Analytic Hierarchy Process, B. Srdjevic, Y. Medeiros, Z. Srdjevic, M. Schaer Jul 2002

Evaluating Management Strategies In Paraguacu River Basin By Analytic Hierarchy Process, B. Srdjevic, Y. Medeiros, Z. Srdjevic, M. Schaer

International Congress on Environmental Modelling and Software

An approach is proposed for evaluating water management strategies in river basins. Reasonably large sets of criterions and objectives are manipulated during a three-phase process by appropriate shrinking and enlarging related decision hierarchies. In the first phase an unrestricted set of management interests are grouped into (1) long-term, and (2) middle- and short-term decision context by creating decision hierarchies and evaluating them by the Analytic Hierarchy Process (AHP). After refining the hierarchies by deleting dominated elements, management plans are introduced at their fingertips and so enlarged hierarchies are repeatedly evaluated by AHP in the second phase. Only two bottom levels …

A Conceptual Approach To Multiple-Model Integration In Whole Site Risk Assessments, E. P. Albers, K. R. Dixon Jul 2002

A Conceptual Approach To Multiple-Model Integration In Whole Site Risk Assessments, E. P. Albers, K. R. Dixon

International Congress on Environmental Modelling and Software

In the past, models have focused on one environmental compartment, a single organism, or specific process. All of these topics are limited in scope and often fail to take into account the more complex interactions of the real world. We have endeavored to change this practice by combining environmental transport models with an animal movement model and a physiologically based toxicokinetics (PBTK) model that has an embedded effects model. The example we will depict consists of a hypothetical contaminant plume within a lake and the impacts on the channel catfish (Ictalurus punctatus). We compared the PBTK output for the multiple-model …
