- 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.

This deft and thorough update ensures that The Wildlife Techniques Manual will remain an indispensable resource, one that professionals and students in wildlife biology, conservation, and management simply cannot do without.

In Medicine of Australian Mammals, more than 30 experts present the most current information available on the medical management of all taxa of Australian native mammals. This comprehensive text is divided into two parts. The first includes chapters on general topics relevant to the medical management of captive and free-ranging Australian native mammals such as: veterinary considerations for the rescue, treatment, rehabilitation and release of wildlife; veterinary aspects of hand-rearing orphaned marsupials; marine mammal strandings and the role of the veterinarian; and wildlife health investigation and necropsy of Australian mammals. The second part covers the medicine of specific taxa of Australian native mammals. Detailed information on taxonomy, distribution, biology, anatomy, physiology, reproduction, husbandry, nutrition, physical and chemical restraint, clinical pathology, hand-rearing, diseases, zoonoses, therapeutics, reproductive management and surgery is included. This practical, one-source reference is complemented by detailed photographs and illustrations, as well as tables listing reproductive and physiological data, diets, haematology and biochemistry values, and drug formularies. Appendices include a checklist of the mammals of Australia and its territories and a guide to the identification of common parasites of Australian mammals. Medicine of Australian Mammals is clinically oriented and is a must-have for veterinary clinicians, no matter how experienced. The book will also be of use to veterinary students, researchers, biologists, zoologists, wildlife carers and other wildlife professionals.

An illuminating look at the challenges and triumphs of state wildlife professionals at the forefront of the fight to protect the American wilderness. The adage "think globally but act locally" defines the work of American wildlife professionals. Their contributions, from remote outposts to major cities, guard the natural world of the entire country. In State Wildlife Management and Conservation, Thomas J. Ryder brings together wildlife leaders from practical, policy, and academic backgrounds to tell the story of state wildlife agencies, chronicling their efforts to restore and protect our nation's natural resources. Reflecting the core principle of the profession—that the public, not any individual, owns wildlife—the book explains how this tenet became law, laying the groundwork for the history of state-level wildlife management that follows. The authors cover key issues, including the limits of private land ownership, the funding of wildlife regulation, the nuances of humanwildlife conflict, the role of law enforcement, disease control efforts, and the challenges involved in balancing the perspectives of hunters, nonhunters, and animal rights advocates. Detailed essays also discuss state management techniques for a wide range of wildlife, including big game and migratory birds. State Wildlife Management and Conservation is a comprehensive, nationwide account of state management efforts. It will aid professors training the next generation of wildlife professionals, students hoping to enter the profession, and anyone working with wildlife to develop a more sophisticated understanding of what it means to be a state wildlife biologist.

This textbook introduces the core competencies, tools and perspectives to manage free-ranging animal population health and demonstrates their need and relevance to help wildlife cope with the ever-increasing pressures of the Anthropocene, manifested by global megatrends such as climate change, urbanization and pollution. It adapts and adopts key concepts of population health from public health and herd health to a wildlife health context. In a highly-accessible and unique form, this book presents a modern way of approaching wildlife and fish epidemiology, health promotion and disease control, with a focus on the social dimensions of wildlife health management. Aimed at graduate students in veterinary medicine, wildlife researchers and health managers this textbook provides a valuable source of information to foster the knowledge and skills needed to protect and promote the health of free-ranging wildlife.
