This book was released on 2013 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Species introduced to the Great Lakes region through shipping, pet trade, and as biological control have caused significant environmental damages and increased costs to boat owners and various water-dependent industries. Once established, some of these species, such as Dreissenid mussels and Eurasian watermilfoil (Myriophyllum spicatum), use recreational boaters as their primary vector of dispersal. Control efforts in the past have focused on boater education efforts and boat washing stations and inspections, yet these can be expensive methods with limited effectiveness. In this study, I construct an invasion model based on a gravity model framework to accurately describe the spread of a simulated invasive species. After parameterization, the constructed model was able to effectively model the human-mediated movements of an invasive species based on historical Dreissenid spread patterns, predicting an average of 78.2% (standard deviation = 0.01%) lakes correctly per model run. I then use the model to attempt to determine the effectiveness of three different invasive species management scenarios in Michigan: deterring boaters from lakes with a high risk of invasion, targeted education at high-risk lakes, and a large-scale education effort. Results indicated that deterring boaters from high-risk lakes is effective in the first five years of an invasion, targeted education is more effective at late stages of an invasion, and large-scale education is effective at all stages of an invasion. Depending on management intensity, the average reduction in the number of invaded lakes ranged from 0.03 at the period of least reduction to 1.49 at the period of greatest reduction when deterring boaters; targeted education and large-scale education reduced the number of invaded lakes by 0.00-1.39 and 0.17-6.00, respectively. Though the management strategies modeled here are theoretical responses to management by recreational boaters, the potential costs of each management scenario in conjunction with these modeled results can inform recommendations to managers attempting to slow the spread and mitigate damages caused by aquatic invasive species.

Book Synopsis Bioeconomics of Invasive Species by : Reuben P. Keller
Download or read book Bioeconomics of Invasive Species written by Reuben P. Keller and published by Oxford University Press. This book was released on 2009-04-22 with total page 316 pages. 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 Invasive Species in a Globalized World by : Reuben P. Keller
Download or read book Invasive Species in a Globalized World written by Reuben P. Keller and published by University of Chicago Press. This book was released on 2014-11-24 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past several decades, the field of invasion biology has rapidly expanded as global trade and the spread of human populations have increasingly carried animal and plant species across natural barriers that have kept them ecologically separated for millions of years. Because some of these nonnative species thrive in their new homes and harm environments, economies, and human health, the prevention and management of invasive species has become a major policy goal from local to international levels. Yet even though ecological research has led to public conversation and policy recommendations, those recommendations have frequently been ignored, and the efforts to counter invasive species have been largely unsuccessful. Recognizing the need to engage experts across the life, social, and legal sciences as well as the humanities, the editors of this volume have drawn together a wide variety of ecologists, historians, economists, legal scholars, policy makers, and communications scholars, to facilitate a dialogue among these disciplines and understand fully the invasive species phenomenon. Aided by case studies of well-known invasives such as the cane toad of Australia and the emerald ash borer, Asian carp, and sea lampreys that threaten US ecosystems, Invasive Species in a Globalized World offers strategies for developing and implementing anti-invasive policies designed to stop their introduction and spread, and to limit their effects.

Book Synopsis Individual and Cooperative Management of Invasive Species in Human-Mediated Landscapes by : Rebecca S. Epanchin-Niell
Download or read book Individual and Cooperative Management of Invasive Species in Human-Mediated Landscapes written by Rebecca S. Epanchin-Niell and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a bioinvasion spreads across a landscape from its point of introduction, damages rise roughly with the square of the distance from the original invasion. It is thus generally beneficial, at the landscape scale, to apply eradication or containment controls early if not immediately upon discovery. However, an individual property owner only has incentives to consider the costs and benefits of control on his/her own property rather than potential landscape-scale damages. Bioinvasions will therefore generally be under-controlled in a landscape of independent owners operating under a laissez-faire system. A mechanism is thus needed to induce early cooperative contributions to control costs from beneficiaries who would, without them, be invaded later. We develop a spatially-explicit, integrated model of invasion spread and human behavior to examine how different degrees of spatial cooperation affect patterns of invasion spread and the total costs and damages imposed. We compare individual laissez-faire, cooperative control by adjacent neighbors, and cooperative control by groups including more distant but nearby neighbors. As expected, private laissez-faire control decisions tend to under-control the invasion relative to socially optimal control under most circumstances. But a reasonably high fraction of first best payoffs can be achieved with only a modest geographical reach of cooperation. We also find that less extensive cooperation is needed to control invasions whose costs and damages otherwise lead to the largest externalities (circumstances with costs that are relatively low compared with damages). This suggests that even small amounts of cooperation to control bioinvasions can provide large social benefits.
Book Synopsis Recreational Boating and the Spread of Aquatic Invasive Species in and Around Lake Tahoe, California-Nevada by : Marion Emmi Wittmann
Download or read book Recreational Boating and the Spread of Aquatic Invasive Species in and Around Lake Tahoe, California-Nevada written by Marion Emmi Wittmann and published by ProQuest. This book was released on 2008 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humans play a critical role in the dispersal of exotic invasive species. Estimating pathways for non-native species by human vectors is a major challenge to invasion biologists, as well as federal, state and regional resource managers. Focusing on dispersal pathways that are available to not just one, but a number of species, allows for the efficient inspection and possible reduction of many exotic species introductions. Transient recreational boating has been used as an estimate of invasion pressure to inland freshwater bodies, and used to predict prior and future species invasions. Specifically, recreational boating traffic is used to predict human-mediated aquatic invasion in the Midwestern United States through the use of spatial interaction models called gravity models. California and Nevada contain some of the largest and most recreationally utilized lakes, rivers and reservoirs in the Western United States. These waterways attract millions of visitor days by boaters not only from within the region, but all over the United States and are currently experiencing increasing numbers of non-native species introductions from the Midwestern U.S.

Book Synopsis A Handbook of Global Freshwater Invasive Species by : Robert A. Francis
Download or read book A Handbook of Global Freshwater Invasive Species written by Robert A. Francis and published by Routledge. This book was released on 2012-03-12 with total page 918 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.
Download or read book An Investigation of Invasion written by and published by . This book was released on 2016 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive species are second only to habitat loss as a leading cause of native species displacement and the management of invasive species costs hundreds of billions annually. Invasion is often conceptualized as a series of stages (Transport, Introduction, Establishment, and Spread), which encourages ecologists to isolate factors that might enable a species to pass from one stage to another and therefore guide prevention or impact management. This thesis addresses each stage of invasion and attempts to determine where management might succeed in preventing invasion or minimizing impacts. The transport and introduction of aquatic invasive species (AIS) was analyzed by conducting a three tier human subjects survey at Tenmile Lake, Oregon over a two year period in which a public boat wash station was built and installed. Assessing boater knowledge of AIS and understanding proper boat cleaning procedure is useful in determining the threat of transport and introduction as overland boater movements is a major vector of AIS. The comparison between pre- and post- boat wash surveys indicate that there is a disconnect between what boaters say they will do and how they actually behave. While 75.9% of boaters from the pre-survey claimed they would use a boat wash station at Tenmile Lake, only 38.5% of post-survey boaters were observed using the station. Furthermore, the surveys identified knowledge gaps of boaters' awareness of AIS. More than 20.0% of boaters surveyed could not verbally name any AIS. To better understand the establishment and spread stages of invasion, I examined the influence of a specific AIS, the New Zealand mud snail (Potamopyrgus antipodarum; NZMS), on benthic food webs throughout three very different aquatic ecosystems (lakes, rivers, and estuaries). Samples of benthic lake, river, and estuarine invertebrates were collected, identified, and counted, and stable isotope analyses (SIA) were conducted on several components of the food web. NZMS densities were found to be dynamic, with population densities fluctuating over time and between locations. A significant negative relationship between NZMS density and community diversity across all ecosystems was found. However, the densities of specific feeding groups had varying positive (omnivores) and negative (herbivores) correlations with NZMS densities. Furthermore, SIA indicated that NZMS don't appear to be competing with native macroinvertebrates for the same food source. NZMS were found to have different influences on each invaded ecosystem, thus management of this particular AIS is difficult once established and spreading. The results of this thesis suggest that prevention of the transport and introduction of NZMS needs to be the focus for future management. Preventative management should include public outreach regarding AIS and proper boat cleaning procedure, and management should also emphasize the need for regional policies and regulations on the transport of AIS rather than site or state specific policies and regulations.
Book Synopsis Fifty Years of Invasion Ecology by : David M. Richardson
Download or read book Fifty Years of Invasion Ecology written by David M. Richardson and published by John Wiley & Sons. This book was released on 2011-01-18 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasion ecology is the study of the causes and consequences of the introduction of organisms to areas outside their native range. Interest in this field has exploded in the past few decades. Explaining why and how organisms are moved around the world, how and why some become established and invade, and how best to manage invasive species in the face of global change are all crucial issues that interest biogeographers, ecologists and environmental managers in all parts of the world. This book brings together the insights of more than 50 authors to examine the origins, foundations, current dimensions and potential trajectories of invasion ecology. It revisits key tenets of the foundations of invasion ecology, including contributions of pioneering naturalists of the 19th century, including Charles Darwin and British ecologist Charles Elton, whose 1958 monograph on invasive species is widely acknowledged as having focussed scientific attention on biological invasions.
Book Synopsis Spatial Modeling as a Decision-making Tool for Invasive Species Management in the Great Lakes by : Jennifer L. Sieracki
Download or read book Spatial Modeling as a Decision-making Tool for Invasive Species Management in the Great Lakes written by Jennifer L. Sieracki and published by . This book was released on 2014 with total page 373 pages. Available in PDF, EPUB and Kindle. 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.
Book Synopsis Invasive Aquatic Species of Europe. Distribution, Impacts and Management by : Erkki Leppäkoski

This book was released on 2013-06-29 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global scale of alien species invasions is becoming more and more evident in the beginning ofthe new millennium. Though the problem ofbiological invasions became a rapidly growing research area, there are large gaps still, both geographically and the matically, to be filled in the near future. This book is the first attempt to provide an overall picture of aquatic species invasions in Europe. Its geographical scope stretches from Irish waters in the west to Volga River and the Caspian Sea in the east, and from Mediterranean in the south up to the Arctic coast of Europe. Not all parts of the continent could be equally covered, as in some countries species invasions are not studied yet. The book tends to represent the array of all major European aquatic systems on the broadest geographical and ecological scope possible from fully saline seas, semi-enclosed brackish water bodies and coastallagoons to freshwater lakes, major river systems and waterways. The key objectives include the present status and impacts caused by non-native aquatic species in European waters. Please note that lengthy species lists submitted for publication and additional informa tion were put on the Internet, as the electronical version of these tables benefits from computer assisted search for data (http://www. ku. lt/nemo/EuroAquaInvaders. htm). Altogether more than 100 scientists from 24 countries have joined to synthesize the available information on bioinvasions. However, the book does not claim to be fully comprehensive.
Book Synopsis Adaptive Aquatic Invasive Species Monitoring of the Lower Fox River in Northeast Wisconsin by : Riley Schultz
Download or read book Adaptive Aquatic Invasive Species Monitoring of the Lower Fox River in Northeast Wisconsin written by Riley Schultz and published by . This book was released on 2024 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of aquatic invasive species (AIS) on ecosystem function and biodiversity are a major concern in the Great Lakes basin, which has been influenced by at least 188 nonindigenous species. In Lake Michigan, lower Green Bay and the Fox River are considered high-risk for species introductions as they may serve as potential vectors between the Great Lakes and inland ecosystems. The Fox River Navigational System Authority (FRNSA) manages 17 locks in the Fox River; and initiated AIS monitoring effort in 2006. University of Wisconsin Green Bay (UWGB) has continued monitoring since 2019. The goal of UWGB AIS sampling is to monitor the presence and assess the distribution of communities in the lower Fox River. In Unit 1, presented are the results of 2022 and 2023 sampling. The findings of this effort necessitated the expansion of monitoring to include early detection surveys in a potential invasion front in this system, Lake Winnebago. UWGB AIS monitoring resulted in WDNR confirmation of the first live spiny waterflea detection in Lake Winnebago. Monitoring systems for AIS require constant adaptation of methods and detection goals as species distributions change. The apparent spread of non-native species has prompted UWGB development of a conceptual plan. Presented in Unit 2, the strategic framework contains species watchlists and methods for an adaptive system wide aquatic invasive species action plan. Through review of early detection management, strategic plans, techniques, protocols, and incorporation of current management, the purpose is to increase accessibility for coordination of future management efforts in the region.
