This book explores how genomic data are revolutionising basic and applied invasion science. It shows how genomic technologies can reveal key drivers of biological invasions, such as hybridisation and rapid adaptation, and illustrates major breakthroughs achieved through the study of model systems. Multiple layers of variation are considered, including epigenetic variation and genetic variation, from chromosomal rearrangements to single nucleotide polymorphisms. Applied topics emphasise state-of-the-art techniques for rapid detection of invasive species, and analytical tools to model their future spread and adaptive potential. Reflecting the breadth of invasion genomics, the chapters span terrestrial and aquatic ecosystems, as well as plant and animal systems. Contributions come from both emerging and established researchers based on all different continents except Antarctica. The book: Includes diverse contributions on a range of systems, authored by well-known experts as well as up-and-coming invasion scientists. Highlights research being performed at the forefront of invasion science. Identifies current research trends and major promising future research directions, bringing cohesion to this dynamic new subfield.This book will be essential for students and researchers working in invasion biology, and those using molecular genetic techniques to study biodiversity, ecology and the spread of alien invasive species.
