Essential Forensic Biology, Second Edition is a fully revised and updated introduction of this highly successful textbook and carefully guides the reader through the science of biology in legal investigations. Now in full colour throughout, the book provides a detailed description of the decay process, and discusses the role of forensic indicators - human fluids and tissues, including blood cells, bloodstain pattern analysis, hair, teeth, bones and wounds. It also considers the role microorganisms, invertebrates and plants play within forensic investigations before considering future directions in forensic science.   The book examines the study of forensic biology in cases of suspicious death, and also explores the organisms used in a range of legal investigations; from human and animal neglect to food spoilage, structural damage, the illegal collection/trade of protected species and bioterrorism. New case studies have been included in this edition with multi choice questions now available at the end of each chapter to enhance student understanding.   An invaluable introductory text for all students taking forensic science courses, the book features a fully integrated website that covers forensic entomology with additional material and figures from the text to enhance student understanding.
