The story of introduced species in Texas is long (hogs were introduced by European settlers in the 1500s) and fraught with controversy. In Unnatural Texas? The Invasive Species Dilemma, Robin W. Doughty and Matt Warnock Turner introduce the “big hitters” of invasive species in the state. They profile the usual suspects—feral hogs, salt cedar, and fire ants—and also lesser known invasives, such as cats and sparrows. Blending natural and environmental history with geography, this book is a much-needed, balanced exploration of invasive species in Texas. The distinctions between native and invasive are not hard and fast, and perceptions of what is invasive have changed over the centuries. A striking example, free-ranging cats—domestic, stray, and feral—can wreak havoc on small mammal and bird populations. There is not a one-size-fits-all solution for invasives, and removal or complete eradication may not be possible or even desirable. The dilemma of what to do about invasive species also raises moral, social, economic, and cultural questions. This engaging introduction to the concept of invasive species in Texas will provide context for readers and will educate people on this important issue facing the state.

Invasive species are among the greatest challenges to environmental sustainability and agricultural productivity in the world. One of the most promising approaches to managing invasive species is voluntary citizen stewardship. However, in order for control measures to be effective, private citizens often need to make sustained and sometimes burdensome commitments. Community-Based Control of Invasive Species is based on five years of research by leading scholars in natural resource and human behavioural sciences, which involved government and citizen groups in Australia and the United States. It examines questions including, 'how can citizens be engaged in voluntarily managing invasive species?', 'what communication strategies will ensure good motivation and coordination?' and 'how can governing bodies support citizens in their efforts?'. With chapters on institutional frameworks, changing governance, systems thinking, organisational learning, engagement, communication and behavioural change, this book will be a valuable reference for researchers and practitioners involved in natural resources management.

Vertebrate invasive species are important ecologically, socially, and scientifically throughout much of the globe. However, the interdiction and options for management of invasive species are driven by localized regulation at the country or even state level and thus the management of species must be framed within that context. This book is focused around the management of invasive vertebrate species in the United States, although readers will find much of the material broadly applicable to invasive species in other regions. Vertebrate invasive species cause damage to agriculture, property, natural resources, and threaten human health and safety. However, most of these species occur in the United States resulting from human-mediated activities, often being released intentionally. For the first time, the wealth of scientific information about vertebrate invasive species in the United States is summarized and synthesized in a single volume to be easily accessible to ecologists and natural resource managers. With a focus on prominent terrestrial invasive species that have a history of policy and management and highlighting contemporary issues and management, this book consists of 18 chapters written by experts from across the United States. The first section of the book focuses on overarching policy and management topics associated with vertebrate invasive species; including biosecurity threats and risk assessment, policy and regulation, and the economics of their management. The second section provides in-depth reviews of noteworthy invasive mammals, birds, amphibians, and reptiles. After finishing this book, the reader should understand the complexity of managing invasive species, the unique challenges that each new species may present, and the steps forward that may decrease the impact of these species on the environment, human health, and the economy.

Invasive species are a major concern for aquatic ecosystems and tropical freshwater snails (Thiaridae) can be very successful invaders. Melanoides tuberculata and Tarebia granifera are two invasive snails in Central Texas that serve as intermediate hosts for several Asiatic trematode parasites of fishes, birds, and other organisms including domestic animals and humans. A better understanding of their temperature tolerances is needed to better predict their spread in Texas and to inform management strategies. Therefore, the goal of my study was to determine the critical thermal minimum of these species and to compare temperature tolerances between species, rivers, and different local morphotype. Survival of snails were monitored in environmental tanks in which temperature was decreased by 0.1°C per hour from 23°C to 10°C. In addition, survival was monitored over time in environmental tanks in which temperature was held constant at 17°C, 15°C, 11°C and 10°C after acclimatization. Temperature tolerances differed significantly between snails from different rivers or river segments. There was no significant difference in survival at colder temperatures between M. tuberculata and T. granifera, nor between local morphotypes of M. tuberculata found in Central Texas. My results show that M. tuberculata can tolerate colder temperatures down to 11oC for a few weeks, which will facilitate their dispersal in rivers of Central Texas farther away from thermally stable spring influenced reaches. Future research should examine differences in temperature tolerances between rivers in central Texas and further examine potential role of local adaptation of M. tuberculata.

The invasive species problem will become increasingly important in the years to come. Trade, travel and tourism are rapidly globalized, and border controls are reduced. This affects natural ecosystems in which aggressive invaders may have disastrous effects. `New' diseases affect human, animal and crop health. The Convention on Biological Diversity presents national authorities with a tall order in coping with this problem. For the first time in one volume, this book presents both ecological, biological and epidemiological aspects of invasive species, as well as the problem of disease organisms for agriculture and human health. The book constitutes a comprehensive background to the global strategy for managing invasive alien species which now is being developed by SCOPE and UNEP. The book is well suited for management staff in various environmental, economic and social sectors. It is essential for university and college teachers, researchers in ecology, natural resources management, and social sciences, as well as M.Sc. and Ph.D. students.

Throughout North America, non-native wild pigs have become an ecologically and economically destructive invasive species. Though they are regarded as a popular game species by some, provide economic benefits to others, and are even engrained into societal heritage in some areas, wild pigs are responsible for an extraordinary amount of damage in both natural and anthropogenic systems throughout North America. As the density and range of wild pig habitat have substantially increased over the last several decades, the magnitude and diversity of their negative impacts are not yet fully realized or quantified. With various conflicts continually emerging, wild pig management is difficult and expensive to achieve. As a result, wild pigs represent one of the greatest wildlife management challenges North America faces in the 21st century. Invasive Wild Pigs in North America: Ecology, Impacts, and Management addresses all aspects of wild pig biology, ecology, damage, and management in a single comprehensive volume. It assimilates and organizes information on the most destructive introduced vertebrate species in the United States, establishing a foundation from which managers, researchers, policy makers, and other stakeholders can build upon into the future. The book provides comprehensive coverage of wild pig biology and ecology, techniques for management and research, and regional chapters. It is an asset to readers interested in wild pigs, the resources they impact, and how to mitigate those impacts, and establishes a vision of the future of wild pigs in North America. Features: Compiles valuable knowledge for a broad audience including wild pig managers, researchers, adversaries, and enthusiasts from across North America Addresses taxonomy, morphology, genetics, physiology, spatial ecology, population dynamics, diseases and parasites, and the naturalized niche of wild pigs Includes chapters on damage to resources, management, research methods, human dimensions and education, and policy and legislation Contains full color images and case studies of interesting and informative situations being created by wild pigs throughout North America Includes a chapter on wild pigs at the wildland–urban interface, a more recent and especially challenging issue
