A Guide to Sample Size for Animal-Based Studies
by
Reynolds PS
A Guide to Sample Size for Animal-based Studies Understand a foundational area of experimental design with this innovative reference Animal-based research is an essential part of basic and preclinical research, but poses a unique set of experimental design challenges. The most important of these are the 3Rs − Replacement, Reduction and Refinement − the principles comprising the ethical framework for humane animal-based studies. However, many researchers have difficulty navigating the design trade-offs necessary to simultaneously minimize animal use, and produce scientific information that is both rigorous and reliable. A Guide to Sample Size for Animal-based Studies meets this need with a thorough, accessible reference work to the subject. This book provides a straightforward systematic approach to "rightsizing" animal-based experiments, with sample size estimates based on the fundamentals of statistical thinking: structured research questions, variation control and appropriate design of experiments. The result is a much-needed guide to planning animal-based experiments to ensure scientifically valid and reliable results. This book offers: Step-by-step guidance in diverse methods for approximating and refining sample size Detailed treatment of research topics specific to animal-based research, including pilot, feasibility and proof-of-concept studies Sample size approximation methods for different types of data − binary, continuous, ordinal, time to event − and different study types − description, comparison, nested designs, reference interval construction and dose-response studies Numerous worked examples, using real data from published papers, together with SAS and R code A Guide to Sample Size for Animal-based Studies is a must-have reference for preclinical and veterinary researchers, as well as ethical oversight committees and policymakers.
Animal Welfare Challenges in Research and Education on Wildlife, Non-Model Animal Species and Biodiversity
by
Sylvina TJ (Editor)
Research to advance understanding of the ecology and biology of wildlife species is more important than ever as the world confronts issues ranging from biodiversity loss to the emergence of zoonotic diseases. However, the current understanding of animal welfare in research and education has been based on laboratory work with specific domesticated species. Wildlife research represents a starkly different context and with different implications for animal welfare. Wild species that are the subject of research have extremely diverse physiologies and behaviors and live in diverse habitats. This makes it challenging and sometimes impossible for wildlife researchers to follow the recommendations outlined in the Guide for the Care and Use of Laboratory Animals (NRC 2011) and other guidelines developed for a laboratory-based, biomedically focused research context. To explore issues associated with the unique welfare considerations of wildlife research, the National Academies of Sciences, Engineering, and Medicine (under the auspices of the Roundtable on Science and Animal Welfare in Laboratory Animal Use), hosted a workshop titled Discussing and Understanding Animal Welfare Challenges in Research and Education on Wildlife, Non-Model Animal Species, and Biodiversity on February 9-10, 2022. The event, held virtually, included pre-recorded presentations and overarching discussions to explore this topic in breadth and depth. More than 1,800 participants from academia, industry, government, and nonprofit organizations joined the webcast. This proceedings summarizes key topics covered in the workshop presentations and discussions based on transcripts, recordings, and slides from the event.

A History of the Development of Alternatives to Animals in Research and Testing
by
Parascandola J
Growing public interest in animal welfare issues in recent decades has prompted increased attention to the efforts to develop alternative, nonanimal methods for use in biomedical research and product testing. In A History of the Development of Alternatives to Animals in Research and Testing, the first book-length study of the subject, John Parascandola traces the history of the concept of alternatives to the use of animals in research and testing in Britain and the United States from its beginnings until it had become firmly established in the scientific and animal protection communities by the end of the 1980s. This account of the history of alternatives is set within the context of developments within science, animal welfare, and politics. The book covers the key role played by animal welfare advocates in promoting alternatives, the initial resistance to alternatives on the part of many in the scientific community, the opportunity provided by alternatives for compromise and cooperation between these two groups, and the dominance of the "Three Rs"--reduction, refinement, and replacement.two groups, and the dominance of the "Three Rs"--reduction, refinement, and replacement.two groups, and the dominance of the "Three Rs"--reduction, refinement, and replacement.two groups, and the dominance of the "Three Rs"--reduction, refinement, and replacement.
