Book excerpt: Due to recent recognition that ballast water is playing an important role in the spread of invasive species within the Great Lakes, there has been increasing interest in implementing management strategies that include a secondary spread component for ballast discharge. Using ballast water data for ships visiting U.S. ports in the Great Lakes, I created a dynamic spatial model to simulate the spread of invasive species based on recent shipping patterns. My goal in producing this model was to provide information to natural resource managers, scientists, and policy-makers to help effectively regulate invasive species issues. In testing the model, I determined that including the number of discharging ship visits that a location receives from previously infested areas and the ability of an organism to survive in the ballast tank were important in more accurately identifying the past spread of the fish virus, viral hemorrhagic septicemia virus (VHSV), zebra mussel (Dreissena polymorpha), and Eurasian Ruffe (Gymnocephalus cernuus), than discharge location alone. I also included and tested a localized spread distance that simulated the dispersal of an invasive species upon being discharged at a location. I first applied the model to identify if ballast water played a role in the secondary spread of VHSV. Results indicated that ballast water movement has contributed to the spread of VHSV in the Great Lakes, albeit it is not the only vector of secondary spread. However, ballast water management would be an important part of any plan in preventing the future spread of VHSV in an ecosystem. Next, I applied the model to predict the future spread of Eurasian Ruffe, which already occurs in the Great Lakes, and two species that do not, golden mussel (Limnoperna fortune) and killer shrimp (Dikerogammerus villosus). The results of the prediction models are intended to be used to help direct early detection monitoring efforts. The Eurasian Ruffe results are currently being used by The Nature Conservancy in their eDNA monitoring efforts, and have led to the positive detection of ruffe eDNA in a location where ruffe has previously not been detected. Finally, I applied the model to identify potentially "safe" ballast water exchange (BWE) sites in Lake Michigan. The purpose of this exercise was to locate mid-lake sites where ships could exchange and flush their ballast tanks, so as to reduce the probability that species are able to survive and establish new populations in the Great Lakes. Potential BWE sites were identified by inputting the results of Lake Michigan circulation models into the ballast water model to determine which sites led to no or minimal spread throughout the Great Lakes. Results of model applications have led to specific predictions for species and management scenarios identified by invasive species managers that have previously not been made for ballast water management in the Great Lakes before.

Available in PDF, EPUB and Kindle. Book excerpt: Biological invasions are one of the strongest drivers of global environmental change, and invasive species are now often in the public discourse. At the same time, economists have begun to take a real interest in determining how invasive species interact with economic systems, and how invaders should be controlled to optimize societal wealth. Although the work from ecologists and economists have both greatly expanded our understanding of the drivers and impacts of invasions, little integration between the fields has occurred that would allow managers and policy-makers to identify the optical expenditures on, for example, prevention and control of invasive species. Because the level of effort expended on invasive species management is intricately linked to the costs and projected benefits of that management, there is an urgent need for greater synthesis between ecology and economics. This book brings ecology and economics together in new ways to address how we deal with the dynamics and impacts of invasive species, and is the outcome fo many years of collaborative research between a small group of economists and ecologists. The outcome is clear demonstration of the utility of combining ecological and economic models for addressing critical questions in the management of invasive species.

Book Synopsis Optimal Spatial-dynamic Resource Allocation Facing Uncertainty by : Kim M. Hall
Download or read book Optimal Spatial-dynamic Resource Allocation Facing Uncertainty written by Kim M. Hall and published by . This book was released on 2014 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: The spatial and temporal behavior of invasive species spread implies that optimal management strategies involve decisions over space and time. Dispersal and propagule pressure are two primary drivers of the spatial-temporal ecological process of species invasion. In the case of riparian communities, stream flow drives the dispersal of vegetation propagules. After arriving at a location, establishment depends in part on propagule pressure. This research incorporates an invasive species spreading through a river network over time --with stochasticity in dispersal, death, and establishment success-- into a dynamic economic decision framework to determine the optimal spatial and temporal pattern of invasive species management efforts. The optimization model employs a Markov Decision Process (MDP) solved using numerical methods. The decision framework developed in this research improves on current economic models by modeling ecological processes of invasion in an explicitly spatial setting with stochasticity to better inform the allocation of management resources. The model is parameterized to simulate the spread and management of the riparian invasive shrub, Tamarix sp., and optimal policies are applied to Monte Carlo simulations over twenty years. Several other rule of thumb policies are applied in the same way for comparison purposes. Results demonstrate that generating management plans through integrating ecology and economic tradeoffs produces management patterns that emphasize a whole-network approach rather than reach by reach; use different management tools in different locations and at different times than economic or ecological models alone; and generates substantial cost savings over other policies. The model demonstrated marked economic efficiency gains in avoided costs by optimal management that reflects the spatial and temporal processes of species invasion. In particular, results showed that simplifications of the ecology that ignores low probability dispersal events lead to costly misspecification of management tool, location and timing. Overall, the integration of key ecological characteristics into a stochastic, spatio-dynamic economic optimization considering the state of the entire river network avoids large errors in the management tool, its location, and its timing that simpler frameworks prescribe.

Book Synopsis Systems Optimization Models to Improve Water Management and Environmental Decision Making by : Omar Alminagorta Cabezas
Download or read book Systems Optimization Models to Improve Water Management and Environmental Decision Making written by Omar Alminagorta Cabezas and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: System models have been used to improve water management and environmental decision making. In spite of the many existing mathematical models and tools that attempt to improve environmental decision making, few efforts have been made to identify how scarce resources (e.g., water, budget) can be more efficiently allocated to improve the environmental and ecological performance of different ecosystems (e.g., wetland habitat). This dissertation presents a set of management tools to improve the environmental and ecological performance. These tools are described in three studies. First, a simple optimization model is developed to help regulators and watershed managers determine cost-effective best management practices (BMPs) to reduce phosphorus load at the Echo Reservoir Watershed, Utah. The model minimizes the costs of BMP implementation to achieve a specified phosphorus load reduction target. Second, a novel approach is developed to quantify wetland habitat performance. This performance metric is embedded in a new optimization model to recommend water allocations and invasive vegetation control in wetlands. Model recommendations are subject to constraints such as water availability, spatial connectivity of wetland, hydraulic infrastructure capacities, vegetation growth and responses to management, plus financial and time resources available to allocate water and invasive vegetation control. Third, an agent-based model is developed to simulate the spread of the invasive Phragmites australis (common reed), one of the most successful invasive plant species in wetlands. Results of the agent-based model are embedded into an optimization model (developed in the second study) to recommend invasive vegetation control actions. The second and third studies were applied at the Bear River Migratory Bird Refuge, which is the largest wetland complex on the Great Salt Lake, Utah. These three studies provide a set of decision-support tools that recommend: (1) BMPs to reduce phosphorus loading in a watershed, (2) management strategies to improve wetland bird habitat, and (3) control strategies to minimize invasive Phragmites spread. Together, these models provide important insights and recommendations for managers to make informed decisions to manage excess nutrients in water bodies as well as to improve wetland management.

This book was released on 2018-05-03 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive alien species are non-indigenous taxa introduced to areas beyond their natural distribution and bio-geographical barriers by human activity, with important impacts on biodiversity, human health and ecosystem services. With the human population being higher than ever before and increasing, together with unprecedented rates of mobility of humans and goods, the introduction of new invasive species is more common than ever and is at the forefront of research in many disciplines such as ecology, epidemiology and food security. The mechanisms of successful introduction, establishment and spread of invasive alien species are highly complex as biological, social, geographic, economic and climatic factors influence the way an invasive species is introduced and determine the options available for its eventual detection and control. With the rapid development of smart sensors, social networks, digital maps and remotely-sensed imagery, spatio-temporal data are more ubiquitous and richer than ever before. The availability of such large datasets (Big data) poses great challenges in data analysis. In addition, increased availability of computing power facilitates the use of computationally-intensive methods for the analysis of such data. Thus new methods are needed to efficiently study and understand biological invasions. A Research Topic held in Frontiers Environmental Informatics aimed to address this topic. Methods are defined in the widest terms and may be analytical, practical or conceptual. Among others, a key aim of the thematic was to maximize the use of the proposed methods/techniques by the scientific community and environmental stakeholders.

This book was released on 2018 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Great Lakes coastal wetlands are some of the most crucial ecosystems to biodiversity in the Great Lakes Basin, yet suffer increasing degradation due to invasive plants. Wetland plant invasions can be controlled in their initial stages, but early detection of invasive plants using field surveys are often untenable due to budget constraints. Remote sensing techniques offer solutions to management objectives during the early stages of invasion on a landscape scale due to their ability to cheaply create spatially explicit information about plant distributions. Some invasive plants, such as Typha x. glauca, are conspicuous on a large scale, and can be mapped to their current extent using new satellite and modeling techniques. Inconspicuous invasive plants however, such as Hydrocharis morsus-ranae, may be undetectable by remote sensing sources and require predictive strategies. In this thesis I explored the use of remote sensing in the management of a conspicuous and inconspicuous invasive wetland plants in the St. Mary's River, MI. I successfully classified the current extent of conspicuous Typha x. glauca and other wetland vegetation types to provide spatially explicit maps for early detection and management and examined methods that can be adapted for use in emergent wetlands worldwide. The habitat suitability of inconspicuous Hydrocharis morsus-ranae was also determined using novel fine-scale habitat covariates determined from lidar and radar. Habitat covariates derived from these sources should see wider use in species distribution modeling, particularly with wetland plants, to create better predictions of invasive plant expansions. Implementation of new and upcoming remote sensing data sources and methods will allow for better invasive wetland plant management at greater spatial and temporal scales than field studies alone."--Boise State University ScholarWorks.

Kvistad and published by . This book was released on 2018 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ballast water is a leading vector for the introduction and secondary spread of aquatic invasive species in the Laurentian Great Lakes. Regional ballast water exchange between ports can accelerate the secondary spread of new aquatic invasive species once introduced, yet ballast water discharges within the Great Lakes are not well regulated. I used an iterative stochastic model to simulate management scenarios at high-priority ports in the Great Lakes shipping network to slow the secondary spread of two potential invaders, golden mussel (Limnoperna fortunei) and monkey goby (Neogobius fluviatilis). I quantified the importance of ports in governing secondary spread in the Great Lakes using graph-theoretic network analysis techniques and calculated six metrics of network centrality for 151 ports in the network: Freeman's degree centrality, indegree centrality, outdegree centrality, betweenness centrality, closeness centrality, and Eigenvector centrality. I then simulated secondary spread scenarios where hypothetical ballast water sanitation was implemented at the top twenty scoring ports in each network centrality metric, as well as the top twenty busiest ports by ship arrivals, and compared the results of each to a scenario where no management action was taken. Simulated secondary spread for both golden mussel and monkey goby resulted in significantly reduced infestation probabilities (p

Available in PDF, EPUB and Kindle. Book excerpt: The dynamic relationship between competing ecological systems has long been and will continue to be one of vital topics in both ecology and mathematical ecology because of its importance and universal existence. Mathematical modeling has become an effective tool to model and simulate the dynamic system, providing decision makers with strategy recommendations. Although a great amount of previous work has attempted to model the biological mechanisms including dispersal, only rarely has there been a systematic investigation on different spatial effects. The author introduces spatial games as a modeling approach with different constructions towards different dynamic systems in order to benefit from the systematic research on spatial dynamics when studying the competing ecological systems. This research developed models of two systems: (1) two-spotted spider mite prey-predator system; (2) tomato spotted wilt virus (TSWV) and west flower thrips (WFT) vector-borne disease system. For two-spotted spider mite system, the author presented four spatial mathematical models as well as a novel spatial game model to describe the spatial movement of two competing species. For the TSWV-WFT system, a spatial game was introduced to describe the spatial dynamics of adult thrips and the novel model was validated with experimental data. The author also gave suggestions for efficiently controlling the vector-borne disease by performing sensitivity analysis towards parameters. The major contribution of this research is to introduce spatial games as a tool to describe the dynamic schemes in ecological systems. Compared to a traditional dynamic model, a spatial game model is more expressive and informative. This approach uses a payoff function and a movement probability function that can be adjusted based on habits, characteristics and mobility schemes of different competing entities, which has enriched its modeling power. The methodology and modeling approach used in this dissertation can be applied to other competing species dynamic systems, and have a broad impact on research areas related to mathematical ecology, biology modeling, epidemiology, pest control, vector-borne disease control, and ecological decision-making processes.
