        Invasive Alien Plants

        Impacts on Development and Options for Management

        by Carol A Ellison, Sean T Murphy, K V Sankaran

        Invasive alien plants pose a major threat to agriculture and livelihoods worldwide. This book considers those impacts and options for biological control, through a case study of mikania weed, a neotropical invasive plant in many countries in the tropical humid forest zones of Southeast Asia. This perennial vine can smother agro-forestry and natural forest ecosystems, as well as many crops within homegarden and plantation production systems. The design of policy frameworks to combat invasive species is considered in depth, as is the use of classical biological control against mikania weed ; 1: Invasive alien plants as a constraint to development in tropical Asia: is there a crisis in the making?2: Profile of an invasive plant: Mikania micrantha3: Social and economic implications of Mikania micrantha in the Kerala Western Ghats4: Impacts and management options for Mikania micrantha in plantations5: Mikania micrantha: its status and impact on people and wildlife in Nepal6: Impact and management of invasive alien plants on Pacific island communities7: Understanding the impact of invasive Mikania micrantha in shifting agriculture and its management through traditional ecological knowledge8: Prevention and related measures for invasive alien plants in India; policy framework and other initiatives9: Control options for invasive alien plants in agroforestry10: Classical biological control of Mikania micrantha: the sustainable solution11: Policy frameworks for the implementation of a classical biological control strategy: the Chinese experience12: Policy frameworks for the implementation of a classical biological control strategy: the Indian experience

        Invasive alien plants and animals are known for their disruption of ecosystems and threat to biodiversity. This book highlights their major impact on human health. This includes not only direct effects through contact with the species via bites, wounds and disease, but also indirect effects caused by changes induced in ecosystems by invasive species, such as more water hyacinth increasing mosquito levels and thereby the potential for malaria. Covering a wide range of case studies from different taxa (animals and plants), and giving an overview of the diverse impacts of invasive species on health in developed and developing countries, the book is a significant contribution that will help in prioritizing approaches to controlling invasive species and mitigating their health effects. It covers invasive plants, marine species, spiders and other arachnids, ticks and dust mites, insects, mosquitos and other diptera, freshwater species (invertebrates and fishes), amphibians and reptiles, birds and mammals. Key Features Collects together the major health impacts for the first time Covers animal and plant invasive species Examines issues in developed and developing countries The broad spectrum of the analyzed case studies will ensure the appeal of the book to a wide public, including researchers of biological invasions, doctors, policy-makers and managers, and students of invasive species in ecology, animal and plant biology and public health medicine.

        Biology and Management of the Formosan Subterranean Termite and Related Species

        by Nan-Yao Su, Chow-Yang Lee, Lauren Davies, Thomas Chouvenc, J. Kenneth Grace, Claudia Husseneder, Shuji Itakura, Hou-Feng Li, Nathan Lo, Kok-Boon Neoh, Wakako Ohmura, Faith M. Oi, Rudolf H. Scheffrahn, Qian Sun, Gaku Tokuda, Edward L. Vargo, Chia-Chien Wu, Koichi Yamamoto

        The Formosan subterranean termite, Coptotermes formosanus, is the most destructive and invasive termite species globally. It is also the only termite species listed in the world's 100 worst invasive alien species of the Global Invasive Species Database. Annually, its infestation costs more than $4 billion in control and damage repairs in the USA alone. This book is the first comprehensive resource drawing on all the literature on C. formosanus since Tokuichi Shiraki first described the species in 1909. The book covers the worldwide distribution of this species, its biogeography, and how it has dispersed from its native range in southern China and Taiwan to different parts of the world. It describes its present taxonomic status and discusses the species' biology, ecology, foraging behavior, physiology, chemical ecology and its association with symbionts. From a practical standpoint, the authors address all of the various management options for this species, such as baits, soil termiticides, wood preservatives, inspection and detection technologies, and Integrated Pest Management (IPM) approaches. Lastly, there are chapters dedicated to another important destructive species, Coptotermes gestroi (the Asian subterranean termite), and the recently discovered C. formosanus/C. gestroi hybrids. This important book is an essential and valuable reference for researchers, graduate students, pest management professionals, chemical manufacturer personnel, building and property managers, and others. It provides readers with a comprehensive understanding of the biology and management of the Formosan subterranean termite and the Asian subterranean termite.

        Community-based Control of Invasive Species

        by Paul Martin, Theodore R. Alter, Donald W. Hine, Tanya M. Howard

        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.

        Parasites and Biological Invasions

        by Jamie Bojko, Alison M Dunn, April M H Blakeslee

        Biological invasions - the introduction, establishment and spread of invasive alien species - are complex global phenomena that can cause significant environmental, ecological, and economic harm. Along with the direct effects of an invasive host organism, there is the additional threat of co-introduced pathogenic and parasitic species. Co-introduced parasites can affect the success of the invasive organism but can also go on to infect hosts in the new range, resulting in novel ecological interactions and complex impacts. These 'Invasive Parasites' can have profound impacts on the success of a biological invasion, and can pose a significant risk to wildlife, in addition to organisms cultured for agriculture and aquaculture. Compiling information on parasite invasions for the first time, this unique book: - provides an in-depth resource on parasite invasions, revealing the subtleties underlying biological invasions and co-introduced disease; - examines the phenomenon and consequences of parasite release in invaded host communities; - explores parasite invasion impacts, interactions and diagnostic techniques; - includes case studies across a broad range of hosts (plants, vertebrates and invertebrates) and parasites (viruses to large Metazoa), from a plethora of aquatic and terrestrial environments. Authored by leading researchers in the discipline, this new book is a useful tool for helping invasion researchers incorporate disease data into their invasion models, as well a vital resource for researchers, policy makers, and environmental managers that are more generally interested in the myriad consequences of species invasions

        Pest Risk Modelling and Mapping for Invasive Alien Species

        by Manuel Colunga-Garcia, Hazel Parry, Catherine Jarnevich, Roger Magarey, Darren Kriticos, Susan Worner, Christelle Robinet, Patrick Tobin, David Cook, Craig Allen, Richard Baker, Marla Downing, Rieks van Klinken, Frank Koch, Denys Yemshanov, Steven Venette. Edited by Robert C Venette.

        Over the past century, the number of species that have been transported to areas outside their native range has increased steadily. New pests and pathogens place biological pressure on valuable resident species, but strict bans may conflict with trading and travel needs. An overview of how the conflict can be managed using pest risk mapping and modelling, this book uses worked examples to explain modelling and help development of tool kits for assessment.

Guerin, Antoine Guisan, Stuart Hall, Jane L. Harbard, Gustavo Heringer, Richard Hill, Patricia M. Holmes, João P. Honrado, Cang Hui, Philip E. Hulme, Brett P. Hurley, Fiona Impson, Cally Jansen, Nolweth

        The book provides a comprehensive overview of current knowledge about "wattles", a large clade of over 1000 species of trees and shrubs in the genus Acacia, most of which are native to Australia. It examines the biology, ecology, evolution, and biogeography of wattles in their native ranges, including the evolutionary forces that have driven past speciation and adaptation to diverse environments, the conservation status, uses and human perceptions of these species. It considers the different histories of the introductions and proliferation of wattles as alien species in different parts of the world since c. 1850 (the Anthropocene), situated within relevant political, socio-economic and scientific contexts, together with an analysis of how awareness of their impacts as invasive species has changed over time. Differences in the dynamics and trends associated with the introduction, naturalization and invasion of wattles in different parts of the world are reviewed. The book also synthesizes the global distribution of wattles using diverse data sources, alongside trends, patterns and projections of global uses of wattles. It discusses the genetics, biotic interactions, and ecological, economic and social impacts of invasive wattles. The first comprehensive global synthesis in book form of aspects of the biology, ecology, biogeography and management of one of the world's most important woody plant genera. Provides the foundation for the assessment of evidence-based information required to formulate sustainable management strategies for non-native plants that have both benefits and negative impacts. Sheds new light on many aspects of plant invasion science. This book is aimed at academics and students in the field of ecology, and at managers of natural and anthropic ecosystems, policy-makers and regulators, and the general public interested in biology and environmental science.

        Plant Invasions

        The Role of Biotic Interactions

        by Anna Traveset, David M Richardson

        Despite many books on plant invasions, none has focused on the role of species interactions. This book is a comprehensive overview of how plant invasions are mediated by varied species interactions and how such invasions influence this important component of biodiversity which involves the interactions (the 'glue') among a community's species. Besides highlighting relevant findings, the book digs deeply into new methodologies to understand species interactions in plant invasions and how this can improve management of invaded communities. The book covers: - Main theories/hypotheses in plant invasion ecology that invoke species interactions - Plant invasions promoted by mutualistic interactions and release from enemies - Antagonistic interactions preventing or hindering plant invasions - Consequences of plant invasions on native species interactions and ecosystem functioning - The interaction network approach to understanding plant invasions - Importance of considering species interactions in managing plant invasions Future avenues of research are highlighted in a final chapter. Table of contents Part I: Background Chapter 1: Plant invasions: the role of biotic interactions – An overview Chapter 2: The role of biotic interactions in invasion ecology: theories and hypotheses Part II: Positive and negative interactions in the soil Chapter 3: Soil biota and non-native plant invasions Part III: Mutualistic interactions that promote plant invasions Chapter 4: Pollination interactions promoting plant invasions- Chapter 5: Seed dispersal interactions promoting plant invasions Chapter 6: Ungulates as dispersal vectors of non-native plants Chapter 7: The role of plant-plant facilitation in non-native plant invasions Chapter 8: How direct and indirect non-native interactions can promote plant invasions, lead to invasional meltdown, and inform management decisions Part IV: Antagonistic interactions that hinder plant invasions Chapter 9: Biotic resistance to plant invasions Chapter 10: EICA 2.0: A general model of enemy release and defence in plant and animal invasions Chapter 11: The role of pathogens in plant invasions Chapter 12: Direct and indirect effects of herbivores influencing plant invasions Part V: Consequences of plant invasions for biotic interactions among native species Chapter 13: Impacts of non-native plants on plant-pollinator interactions Chapter 14: The effect of non-native plant invasions on seed dispersal of native plants Chapter 15: Allelopathic disruptions of biotic interactions due to non-native plants Chapter 16: Competition between native and non-native plants Chapter 17: Indirect biotic interactions between non-native plants and native plants and animals Part VI: Novel techniques and experimental approaches in the study of plant invasions Chapter 18: How a network approach has advanced the field of plant invasion ecology Chapter 19: Molecular ecology of plant-microbial interactions during invasions: progress and challenges Part VII: Biotic interactions and the management of ecosystems invaded by non-native plants Chapter 20: How can progress in the understanding of antagonistic interactions be applied to improve biological control of plant invasions?
