The value of the canine nose is well-documented, and working dogs are being utilized for their olfactory skills in an increasing number of fields. Not only are dogs used by police, security, and the military, but they are also now used in forensic science, in medical detection of disease, in calculating population trends of endangered species and e

Detection canines have been utilized throughout the world for over a century, and while numerous attempts have been made to replicate the canine’s ability to detect substances by mechanical means, none has been as successful. The olfactory system is a highly intricate and sophisticated design for chemical sensing, and the olfactory capacity of many animals, including canines, is considered unmatched by machine due to not only their great sensitivity and superior selectivity but also their trainability and mobility. These unique features have led to the use of such animals as "whole-animal" biosensors. Amplifying the benefits and diminishing the limitations of detection canines' interdisciplinary research is crucial to understanding canine olfaction and detection and enhancing this powerful and complex detector. The past 50 years have produced vast advancements in animal behavior/training technology to develop canines into more proficient and reliable sensors, while scientific research has provided tremendous support to help practitioners better understand how to utilize this powerful sensor. This book assembles a diverse group of authors with expertise in a variety of fields relating to detection canines and the chemical sensing industry, including both research and operational perspectives on detection canines. It illustrates how science enhances our understanding of how canines are employed for solving some of the world’s leading detection challenges.

Death, Decomposition, and Detector Dogs: From Science to Scene, Second Edition is designed to help canine handlers, detectives, death investigators, crime scene personnel (including forensic laboratory personnel, technicians, and supervisors), and attorneys understand the science involved when utilizing human remains detector (HRD) canines as a locating tool. The book covers the basic anatomy and physiology of canine olfaction and the unique characteristics of their scenting ability that allows dogs to be trained to locate distinct odors. Using concise and clear explanations and photographs, the book reviews the science of forensic taphonomy. Factors that may affect the decomposition process are highlighted along with what the potential outcomes that may be encountered. The book examines how the odor of human remains is generated through various stages of decomposition and the manner in which environmental conditions in both land and water settings may affect that odor. Different types of background information that may help in determining possible search locations for missing individuals are included as well as assist the HRD canine handler in developing search plans are covered. Different tools and technologies that may be used in addition to an HRD canine team are included to help readers understand that are many ways to address searching for a decedent. Several case reports involving decedents, found in both land and water settings in addition to different weather conditions, are included to help the reader understand how the environment may have affected the condition of the decedent. This edition includes more case reports explaining how environmental factors were considered in HRD canine deployments in both land and water settings. Understanding which variables—and how such variables—can affect the state and condition of human remains, as well as dispersion of odor from human remains, will help canine handlers utilize their HRD canine more effectively as a locating tool. Death, Decomposition, and Detector Dogs, Second Edition will help HRD canine handlers and other law enforcement personnel be better prepared to meet the challenges of their jobs before, during, and after searches for the missing.

This book unites cutting-edge research related to various aspects of dog olfaction. It includes rich expertise about detection dogs with application perspectives, and expands beyond. In four clearly arranged sections, readers will discover specialist contributions on: the fundamentals of olfaction, anatomy, comparative olfactory neuroscience and dysfunction methodological reflections on canine olfactometry and essential implications for practice, comprising dog selection for scent detection, handler bias and signal detection concepts the connection with dog behavior, cognition, welfare, and learning and training methods diverse application examples of dog olfactory capabilities, such as disease detection for diagnostics, infectious disease surveillance, forensics and ecological conservation The unique and exciting link between science and practice makes this book a valuable read not only for researchers, but also for practicing veterinarians and professionals in the fields of canine detection, chemical sensing, working dog behavior and welfare.

Forensic Science: The Basics, Fourth Edition is fully updated, building on the popularity of the prior editions. The book provides a fundamental background in forensic science, criminal investigation and court testimony. It describes how various forms of evidence are collected, preserved and analyzed scientifically, and then presented in court based on the analysis of the forensic expert. The book addresses knowledge of the natural and physical sciences, including biology and chemistry, while introducing readers to the application of science to the justice system. New topics added to this edition include coverage of the formation and work of the NIST Organization of Scientific Area Committees (OSACs), new sections on forensic palynology (pollen), forensic taphonomy, the opioid crisis, forensic genetics and genealogy, recent COVID-19 fraud schemes perpetrated by cybercriminals, and a wholly new chapter on forensic psychology. Each chapter presents a set of learning objectives, a mini glossary, and acronyms. While chapter topics and coverage flow logically, each chapter can stand on its own, allowing for continuous or selected classroom reading and study. Forensic Science, Fourth Edition is an ideal introductory textbook to present forensic science principles and practices to students, including those with a basic science background without requiring prior forensic science coursework.
