Foundations of Wildlife Diseases is a comprehensive overview of the basic principles that govern the study of wildlife diseases. The authors integrate theoretical foundations with a thorough examination of the factors that can affect the health and fitness of animals. They include specific information on a wide array of infectious agents such as bacteria, viruses, arthropods, fungi, protista, and helminths, as well as immunity to these agents. Also provided is a foundation for the study of noninfectious diseases, cancers, and prion diseases that affect wildlife. Supporting students, faculty, and researchers in areas related to wildlife management, biology, and veterinary sciences, this volume fills an important gap in wildlife disease resources, focusing on mammalian and avian wildlife while also considering reptiles and amphibians. Foundations of Wildlife Diseases provides students with a structure for thinking about and understanding infective agents and their interactions with wildlife. Each chapter includes an outline, select definitions and concepts, an overview and summary, and literature cited. Ê
Emerging infectious diseases pose an increasingly serious threat to a number of endangered or sensitive species and are increasingly recognized as one of the major factors driving species extinction. Despite the significant impact of pathogens on conservation, no single book has yet integrated the theoretical principles underlying disease transmission with the practical health considerations for helping wildlife professionals and conservation biologists to manage disease outbreaks and conserve biodiversity. This novel and accessible book starts with a foundational section focusing on the role of pathogens in natural ecosystems, the dynamics of transmission in different environments, and the factors driving wildlife disease outbreaks. It then moves on to more applied issues concerned with the acquisition of field data including sampling, experimental design and analysis, as well as diagnostic analyses in both the laboratory and field. Guidelines for effective modelling and data analysis follow, before a final section is devoted to disease prevention and control including the prevention of novel outbreaks, the use of diseases as biocontrol agents, and the associated issues of ethics, public communication, and outreach. Infectious Disease Ecology and Conservation is primarily aimed at advanced undergraduates, graduate students, and established researchers in the fields of conservation biology, disease ecology, population ecology, and veterinary science. It will also be a valuable reference for conservation practitioners, land managers, and wildlife professionals who are required to deal with disease outbreak problems.
- A hypothesis is a proposition, set forth as an explanation for the occurrence of a phenomenon, that can be tested. - The basis for scientific investigation is the collection of information to formulate and test hypotheses. - Experimental methods measure the effect of manipulations caused by the investigator; observational methods collect information about naturally occurring events. - There are three sub-types of experimental techniques that differ in the way subjects are chosen for inclusion in the study, in the amount of control that the investigator has over variables, and in the method used to assess changes in other variables. - Descriptive observational studies dominate the early phase of most investigations and involve the description of disease-related events in the population. Associations among factors may be observed but the strength of the associations is not measured. - Analytical observation al techniques are of three basic types: prevalence surveys, case:control studies, and incidence or cohort studies. All attempt to explain the nature of relationships among various factors and to measure the strength of associations. - Prevalence surveys and case:control studies deal with disease existing at the time of the study; incidence studies are concerned with the development of disease over time. - Observational studies may be retrospective, using existing data, or prospective with collection of new information.
Shared diseases among wildlife, livestock and humans, often transboundary, are relevant to public health and global economy, as being highlighted currently relative to the global COVID19 pandemic. Diseases at these interfaces also impact the conservation of biodiversity and must be considered when managing wildlife. While wildlife and domestic livestock have coexisted in dynamic systems for thousands of years, spillover disease risks are higher today than in the past due to global patterns of increasing close contact and interactions among wildlife, livestock and humans in the context of complex, diverse and numerous circumstances. Multidisciplinary studies of animal interfaces, especially those involving wildlife, therefore, must be brought to the forefront so that knowledge gaps can be realized and filled to inform managers and policy makers. In the first part of the book authors illustrate and discuss ecological and epidemiological concepts related to the interfaces, with a vision towards socio-ecological system health. In addition, the history of past animal interfaces provides the necessary perspective to focus current questions, better understand present situations, and informs how we can best approach the future. The second part discusses the myriad of similar and differing wildlife- livestock interfaces found around the world from a regional point of view. The third part focuses on how to assess the spatial and temporal overlap between livestock and wildlife, and authors present new technical innovations about how inter-transmissions between wild and domestic populations can be quantified. An overview of main modeling approaches available to quantify multi-host disease transmission at the wildlife/livestock interface, illustrated with specific-case studies, is also presented. Finally, the need for interdisciplinary approaches and a dedicated thematic field to approach the wildlife/livestock interfaces and create opportunities to promote wildlife–livestock coexistence is emphasized. The concluding chapter presents perspectives and directions to better understanding disease dynamics at the wildlife/livestock interface, global change and implications for the future. The changing distribution of interfaces, ongoing human and environmental changes (e. g. climate warming, changes in animal production systems, etc.) and their likely impacts and consequences for the interfaces and disease transmission processes are all discussed.
The study of epidemiology is an essential part of understanding how infectious diseases emerge, and how they affect humans, wildlife and wildlife conservation. The integration of modelling techniques with parasitology and population dynamics has been hugely significant for our understanding of disease dynamics. This book on wildlife epidemiology brings the subject right up to date, covering the most recent empirical and theoretical developments in the field.
Provides wildlife professionals with cutting-edge scientific information on the most damaging and newly emerging wildlife diseases. Wildlife diseases and their implications are at the forefront of many sectors of scientific endeavor, especially in the wake of the COVID-19 pandemic. Nearly 60 percent of all human diseases and 75 percent of all emerging infectious diseases are zoonotic. Edited by pioneering wildlife veterinarians David A. Jessup and Robin W. Radcliffe, Wildlife Disease and Health in Conservation explores the origins and impacts of as well as the responses to the most damaging and persistent diseases currently threatening wildlife conservation. Focusing mainly on newer, invasive, and controversial wildlife health challenges, this book also reexamines classic diseases that provide warnings and important lessons for wildlife professionals and policy makers. Each chapter offers cutting-edge scientific information and extensive references to help readers plan for, respond to, and conduct research on these serious health challenges. This book: • Reports crucial findings on newly emerging diseases and how to recognize and manage them • Explores the health of critical but often neglected aquatic ecosystems, including both vertebrate and invertebrate examples • Covers a vast diversity of wildlife health threats, from epizootic bighorn sheep pneumonia and African swine fever to sea star wasting disease, avian influenza, and rabbit hemorrhagic disease • Explains zoonotic dangers to humans, including coronaviruses • Includes information on marine and aquatic species, wild ungulate species, carnivores and omnivores, birds, and more • Provides insight into the social, legal, financial, and political factors that may override or influence conservation priorities in response to biomedical challenges Featuring detailed and attractive field notes–style illustrations by Laura Donohue and essential essays from experts in the field, Wildlife Disease and Health in Conservation combines theory and practice to inform and inspire wildlife health and conservation.
Pathology of Wildlife and Zoo Animals is a comprehensive resource that covers the pathology of wildlife and zoo species, including a wide scope of animals, disease types and geographic regions. It is the definitive book for students, biologists, scientists, physicians, veterinary clinicians and pathologists working with non-domestic species in a variety of settings. General chapters include information on performing necropsies, proper techniques to meet the specialized needs of forensic cases, laboratory diagnostics, and an introduction into basic principles of comparative clinical pathology. The taxon-based chapters provide information about disease in related groups of animals and include descriptions of gross and histologic lesions, pathogenesis and diagnostics. For each group of animals, notable, unique gross and microscopic anatomical features are provided to further assist the reader in deciding whether differences from the domestic animal paradigm are "normal."
