Crossing Boundaries, Crossing Scales: The Evolution of Environment and Resource Co-Management - Plummer - 2007 - Geography Compass - Wiley Online Library

Crossing Boundaries, Crossing Scales: The Evolution of Environment and Resource Co-Management - Plummer - 2007 - Geography Compass - Wiley Online Library: "As an approach to mediating human–environment interactions, the co-management of natural resources influences a diverse array of geographic endeavors. This article chronicles the development of the concept from its historical roots to the more recent past, where it has gained prominence as a tenable solution in situations of competing property claims and as a model of environmental governance. In surveying more that 15 years of experience with co-management, we draw attention to several points of contention or debate, including concerns about power-sharing and representation in co-management arrangements, and the imprecise use of the term."

BioOne Online Journals - Validation of a Demographic Model for Woodland Caribou

BioOne Online Journals - Validation of a Demographic Model for Woodland Caribou: "Wildlife population models are potentially valuable for conservation planning. Validation is necessary to ensure that models are sufficiently robust for predicting management outcomes consistent with conservation objectives. Sorensen et al. (2008) produced a model of woodland caribou (Rangifer tarandus) population growth rate that was recently modified and used as a predictive tool at several scales."

BioOne Online Journals - Managing Complex Problems in Rangeland Ecosystems

BioOne Online Journals - Managing Complex Problems in Rangeland Ecosystems "Management of rangelands, and natural resources in general, has become increasingly complex. There is an atmosphere of increasing expectations for conservation efforts associated with a variety of issues from water quality to endangered species. We argue that many current issues are complex by their nature, which influences how we approach them. We define a complex problem as one that varies in time and space. In other words, one answer may not be correct for all sites or during all years. For simple problems a generalized answer may be sufficient, and even for complex problems, general rules provide a good starting point."

Does formal system dynamics training improve people's understanding of accumulation? - Sterman - 2010 - System Dynamics Review - Wiley Online Library

Does formal system dynamics training improve people's understanding of accumulation? - Sterman - 2010 - System Dynamics Review - Wiley Online Library: "Research shows widespread misunderstanding of stocks and flows, even among highly educated adults. People fail to grasp that any stock rises (falls) when the inflow exceeds (is less than) the outflow. Rather, people often use the correlation heuristic, concluding that a system's output is positively correlated with its inputs."

Change resistance as the crux of the environmental sustainability problem - Harich - 2010 - System Dynamics Review - Wiley Online Library

Change resistance as the crux of the environmental sustainability problem - Harich - 2010 - System Dynamics Review - Wiley Online Library: "Why, despite over 30 years of prodigious effort, has the human system failed to solve the environmental sustainability problem? Decomposing the problem into two sequential subproblems, (1) how to overcome change resistance and (2) how to achieve proper coupling, opens up a fresh line of attack. A simulation model shows that in problems of this type the social forces favoring resistance will adapt to the forces favoring change."

ECOLOGICAL-ECONOMIC MODELS OF SUSTAINABLE HARVEST FOR AN ENDANGERED BUT EXOTIC MEGAHERBIVORE IN NORTHERN AUSTRALIA - BRADSHAW - 2008 - Natural Resource Modeling - Wiley Online Library

ECOLOGICAL-ECONOMIC MODELS OF SUSTAINABLE HARVEST FOR AN ENDANGERED BUT EXOTIC MEGAHERBIVORE IN NORTHERN AUSTRALIA - BRADSHAW - 2008 - Natural Resource Modeling - Wiley Online Library: "Here we analyze the ecological and economic costs/benefits of a series of potential harvest management options for Australia's banteng population, with the aim being either to: (1) maximize sustainable yield (MSY); (2) maximize harvest of trophy males; (3) maximize indigenous off-take; (4) suppress density or completely eradicate the population; (5) minimize risk of extinction whilst limiting range expansion; (6) scenarios incorporating two or more of options 1–5. The modeling framework employed stochastic, density-regulated matrix population models with life-history parameters derived from (i) allometric relationships (for estimating rmax, generation length, fecundity and densities for a banteng-sized mammal) and (ii) measured vital rates for wild and captive banteng and other Bos spp."

COOPERATIVE MODELING: BUILDING BRIDGES BETWEEN SCIENCE AND THE PUBLIC1 - Cockerill - 2007 - JAWRA Journal of the American Water Resources Association - Wiley Online Library

COOPERATIVE MODELING: BUILDING BRIDGES BETWEEN SCIENCE AND THE PUBLIC1 - Cockerill - 2007 - JAWRA Journal of the American Water Resources Association - Wiley Online Library: "As freshwater resources become more scarce and water management becomes more contentious, new planning approaches are essential to maintain ecologic, economic, and social stability. One technique involves cooperative modeling in which scientists and stakeholders work together to develop a computer simulation model to assist in planning efforts."

Improving model understanding using statistical screening - Taylor - 2009 - System Dynamics Review - Wiley Online Library

Improving model understanding using statistical screening - Taylor - 2009 - System Dynamics Review - Wiley Online Library: "System dynamics models are often constructed to improve system performance by identifying and modifying feedback mechanisms that drive system behavior. Once identified, these feedback mechanisms can be used to design and test policies for system performance improvement. A preliminary step in developing policies is the identification of high-leverage parameters and structures, the influential model sections that drive system behavior. The current work clarifies and extends the use of statistical screening as a tool to improve model understanding, explanation, and development with a six-step process."

REVIEW: The management of wild large herbivores to meet economic, conservation and environmental objectives - GORDON - 2004 - Journal of Applied Ecology - Wiley Online Library

REVIEW: The management of wild large herbivores to meet economic, conservation and environmental objectives - GORDON - 2004 - Journal of Applied Ecology - Wiley Online Library: "Wild large herbivores provide goods and income to rural communities, have major impacts on land use and habitats of conservation importance and, in some cases, face local or global extinction. As a result, substantial effort is applied to their management across the globe. To be effective, however, management has to be science-based. We reviewed recent fundamental and applied studies of large herbivores with particular emphasis on the relationship between the spatial and temporal scales of ecosystem response, management decision and implementation."

A participatory modelling approach to support integrated sustainability assessment processes - Videira - 2010 - Systems Research and Behavioral Science - Wiley Online Library

A participatory modelling approach to support integrated sustainability assessment processes - Videira - 2010 - Systems Research and Behavioral Science - Wiley Online Library: "Several authors have described the usefulness of participatory system dynamics approaches in environmental decision-making processes, particularly in supporting problem scoping and policy analysis. This paper explores how these approaches may be expanded to provide a coherent, deliberative platform, which structures Integrated Sustainability Assessments (ISA) of policy proposals. The proposed ISA framework forms a five-stage feedback and learning process including scoping, visioning, model building, simulation/assessment and monitoring."

Models for management of wildlife populations: lessons from spectacled bears in zoos and grizzly bears in Yellowstone - Faust - 2004 - System Dynamics Review - Wiley Online Library

Models for management of wildlife populations: lessons from spectacled bears in zoos and grizzly bears in Yellowstone - Faust - 2004 - System Dynamics Review - Wiley Online Library: "Models of population dynamics are frequently used in the management and conservation of wildlife populations. They provide a powerful method of quantitatively assessing a population's risk of decline and determining the potential to reverse the decline. Models from recent studies of managed populations are presented. The first model simulates the spectacled bear populations maintained in American Zoo and Aquarium Association (AZA) zoos. The second model simulates the grizzly bear population in the Greater Yellowstone Ecosystem (GYE). The article concludes with a discussion of system dynamics modeling in the larger context of population dynamics modeling."

Lightening the performance burden of individual-based models through dimensional analysis and scale modeling - Osgood - 2009 - System Dynamics Review - Wiley Online Library

Lightening the performance burden of individual-based models through dimensional analysis and scale modeling - Osgood - 2009 - System Dynamics Review - Wiley Online Library: "While individual-based models are attractive for some modeling problems, the lengthy times required for simulating large populations can impose high opportunity costs by limiting model comprehension, refinement and user interaction. This paper demonstrates a novel technique for using dimensional analysis and scale modeling to reduce the performance barriers associated with individual-based model simulation."

Applying methodological pluralism to wildlife and the economy

Methodological pluralism is important when we study complex systems. We aim to show that methodological pluralism yields additional insight by applying it to a specific question: how are the economy and wildlife related in developed and developing countries? We identify three possible ingredients of methodological pluralism: (1) using both qualitative and quantitative information; (2) tapping the potential of history to illuminate slow-moving variables; and (3) explicitly synthesizing either individually or in groups, by thinking about the corresponding system.
