This new volume on Biological Invasions deals with both plants and animals, differing from previous books by extending from the level of individual species to an ecosystem and global level. Topics of highest societal relevance, such as the impact of genetically modified organisms, are interlinked with more conventional ecological aspects, including biodiversity. The combination of these approaches is new and makes compelling reading for researchers and environmentalists.
This open access volume presents a comprehensive account of all aspects of biological invasions in South Africa, where research has been conducted over more than three decades, and where bold initiatives have been implemented in attempts to control invasions and to reduce their ecological, economic and social effects. It covers a broad range of themes, including history, policy development and implementation, the status of invasions of animals and plants in terrestrial, marine and freshwater environments, the development of a robust ecological theory around biological invasions, the effectiveness of management interventions, and scenarios for the future. The South African situation stands out because of the remarkable diversity of the country, and the wide range of problems encountered in its varied ecosystems, which has resulted in a disproportionate investment into both research and management. The South African experience holds many lessons for other parts of the world, and this book should be of immense value to researchers, students, managers, and policy-makers who deal with biological invasions and ecosystem management and conservation in most other regions.
By the sixth year of the American Revolution, Britain determined that Virginia would be the key to subduing the entire rebellion. The American War for Independence was fought in nearly every colony, but some colonies witnessed far more conflict than others. In the first half of the war, the bulk of military operations were concentrated in Massachusetts, New York, New Jersey, and Pennsylvania. Following the battle at Monmouth Courthouse, New Jersey, in 1778, British strategy moved to the South, where their armies clashed with Continental troops in Georgia and South Carolina. Surprisingly, Virginia saw little fighting up to this point in the war. This changed suddenly in 1781, when the turncoat Benedict Arnold led 1,600 seasoned British troops on a successful raid up the James River to Richmond, destroying Patriot property along the way. Arnold's bold stroke demonstrated Virginia's vulnerability to attack and the possibility that the colonies could be divided and subdued piecemeal. British General Henry Clinton decided to reinforce Arnold in Virginia, while events in North Carolina, including the battle of Guilford Courthouse, convinced British General Charles Cornwallis that defeating the Patriots in Virginia was the key to ending the war. As historian Michael Cecere relates in The Invasion of Virginia 1781, the war's arrival in the largest colony had unintended consequences for Cornwallis and his powerful British force. -- Inside jacket flap.
Early in the seventeenth century, Northeast Asian politics hung in a delicate balance among the Chosŏn dynasty in Korea, the Ming in China, and the Manchu. When a Chosŏn faction realigned Korea with the Ming, the Manchu attacked in 1627 and again a decade later, shattering the Chosŏn-Ming alliance and forcing Korea to support the newly founded Qing dynasty. The Korean scholar-official Na Man’gap (1592–1642) recorded the second Manchu invasion in his Diary of 1636, the only first-person account chronicling the dramatic Korean resistance to the attack. Partly composed as a narrative of quotidian events during the siege of Namhan Mountain Fortress, where Na sought refuge with the king and other officials, the diary recounts Korean opposition to Manchu and Mongol forces and the eventual surrender. Na describes military campaigns along the northern and western regions of the country, the capture of the royal family, and the Manchu treatment of prisoners, offering insights into debates about Confucian loyalty and the conduct of women that took place in the war’s aftermath. His work sheds light on such issues as Confucian statecraft, military decision making, and ethnic interpretations of identity in the seventeenth century. Translated from literary Chinese into English for the first time, the diary illuminates a traumatic moment for early modern Korean politics and society. George Kallander’s critical introduction and extensive annotations place The Diary of 1636 in its historical, political, and military context, highlighting the importance of this text for students and scholars of Chinese and East Asian as well as Korean history.
There are many hypotheses describing the interactions involved in biological invasions, but it is largely unknown whether they are backed up by empirical evidence. This book fills that gap by developing a tool for assessing research hypotheses and applying it to twelve invasion hypotheses, using the hierarchy-of-hypotheses (HoH) approach, and mapping the connections between theory and evidence. In Part 1, an overview chapter of invasion biology is followed by an introduction to the HoH approach and short chapters by science theorists and philosophers who comment on the approach. Part 2 outlines the invasion hypotheses and their interrelationships. These include biotic resistance and island susceptibility hypotheses, disturbance hypothesis, invasional meltdown hypothesis, enemy release hypothesis, evolution of increased competitive ability and shifting defence hypotheses, tens rule, phenotypic plasticity hypothesis, Darwin's naturalization and limiting similarity hypotheses and the propagule pressure hypothesis. Part 3 provides a synthesis and suggests future directions for invasion research.
In this edited volume, global experts in ecology and evolutionary biology explore how theories in ecology elucidate the processes of invasion, while also examining how specific invasions inform ecological theory. This reciprocal benefit is highlighted in a number of scales of organization: population, community and biogeographic. The text describes example invaders in all major groups of organisms and from a number of regions around the globe.
Invasive species have come to dominate 3% of the Earth’s ice-free surface, constituting one of the most serious ecological and economic threats of the new millennium, and freshwater systems are particularly vulnerable. This book examines the identity, distribution, and impact of freshwater non-indigenous species and the dynamics of their invasion. It focuses on old and new invaders and provides a starting point for further research.
Biological invasions are considered to be one of the greatest threats to the integrity of most ecosystems on earth. This volume explores the current state of marine bioinvasions, which have been growing at an exponential rate over recent decades. Focusing on the ecological aspects of biological invasions, it elucidates the different stages of an invasion process, starting with uptake and transport, through inoculation, establishment and finally integration into new ecosystems. Basic ecological concepts - all in the context of bioinvasions - are covered, such as propagule pressure, species interactions, phenotypic plasticity, and the importance of biodiversity. The authors approach bioinvasions as hazards to the integrity of natural communities, but also as a tool for better understanding fundamental ecological processes. Important aspects of managing marine bioinvasions are also discussed, as are many informative case studies from around the world.
There are many books on aspects of plant invasions, but none that focus on the key role of species interactions in mediating invasions. This book reviews exciting new findings and explores how new methods and tools are shedding new light on crucial processes in plant invasions. This book will be of interest to academics and students of ecology, researchers engaged in developing management solutions, scientific managers of natural ecosystems, and policy-makers.
