Invasive Species

Of the 7000 estimated non-native species present in North America approximately 1000 are invasive. Clearly invasive species are in the minority but their small numbers don''t keep them from causing billions of dollars in economic and ecological harm each year. Policymakers and ecologists continue to try to figure out which species might be harmful which invasive species are doing the most damage and which of these might respond best to eradication efforts. Invasive species reports and case studies are prevalent in political environmental and scientific news cycles and a significant portion of the public is concerned about the issue. In Invasive Species: What Everyone Needs to Know? Simberloff will first cover basic topics such as how non-native species are introduced which areas have incurred the most biological invasions and how the rates of biological invasions have shifted in recent years. He then moves on to the direct and indirect impacts of the impacts of invasive species on various ecosystems such as habitat and resource competition how invasive species transmit pathogens and how introduced plants and animals can modify a habitat to favor other non-native species. Simberloff''s final chapters will discuss the evolution of invasive species the policies we currently have in place to manage them and future prospects for controlling their spread. The book will also contain a section dedicated to the more controversial topics surrounding invasive species: invasive natives useful non-native species animal rights versus species rights and non-native species'' impacts on the biodiversity of an ecosystem.What Everyone Needs to Know? is a registered trademark of Oxford University Press. is a registered trademark of Oxford University Press.
