The third edition of this essential introductory text has been fully updated in light of the genomics revolution. Providing authoritative and engaging coverage for students and professionals of conservation genetics and genomics, conservation biology, and wildlife biology, the authors explain the underpinning mathematics clearly and accessibly throughout. The critical link between theory and practice, so often obscured in applied genetics, is illuminated in each chapter through examples of diverse conservation issues (including strengthened plant coverage), the solutions needed, and detailed step-by-step guides on how genetic principles can be applied. Self-learning is further facilitated through problem sets with solutions, case studies, main point boxes, symbol and software lists, and approximately 600 engaging full-color photos and 300 graphics which relate genetic processes to species level conservation. Highlighting the interdependence between 'ecology' and 'genetics,' this text is educationally rich and visually stunning. Accessible, educationally rich, and full-color introduction to conservation genetics, fully updated in light of the genomics revolution. Richard Frankham is a leading international figure in conservation genetics, through pioneering research on the genetic impacts of small population sizes and as senior author of the first textbooks in the field. Jonathan D. Ballou is a Research Scientist Emeritus at the Smithsonian Conservation Biology Institute in Washington, D.C. His research focuses on the genetic and demographic problems confronted by small populations, especially of threatened species. Catherine E. Grueber is an Associate Professor and coleads the Applied and Evolutionary Zoology Group at The University of Sydney. Her team investigates the interactions between population genetic problems and conservation actions. Melinda Pickup is a conservation geneticist who works as a research scientist at Greening Australia and is an adjunct fellow at Macquarie University. Melinda's core interests are in plant conservation and restoration genetics, plant mating systems, pollination ecology, plant traits, and seed biology. Adam J. Stow is a Professor at Macquarie University in Sydney, Australia, renowned for his expertise in science communication. He has made significant contributions to environmental education, including serving as the director of a Master's-level program in conservation.
