Book Description
This book signaled a shift in the understanding of the global reorganization of biological species during the Anthropocene. The encouragement of acclimatization and naturalization of new species gave way to managing the ramifications of the changes that introductions bought to ecologies, landscapes and environments. The 19th century environments of the new world - land and sea - became testing grounds for the introduction of new assemblages of people and plants, economies and animals, cultures and coastlines. But some species became out-of-control threats to environments across the globe. These changes have enduring impacts, some adverse, some beneficial, that are dynamic, unpredictable and often oscillating.
