Primatology draws on theory and methods from diverse fields, including anatomy, anthropology, biology, ecology, medicine, psychology, veterinary sciences and zoology.The more than 500 species of primate range from tiny mouse lemurs to huge gorillas, and primatologists collect data in a variety of environments including in the field, research facilities, museums, sanctuaries, zoos, and from the literature.The variability in research interests, study animals and research sites means that there are no standard protocols for how to study primates.Nevertheless, asking good questions and designing appropriate studies to answer them are vital to produce high quality science.This accessible guide for graduate students and post-doctoral researchers explains how to develop a research question, formulate testable hypotheses and predictions, design and conduct a project and report the results.The focus is on research integrity and ethics throughout, and the book provides practical advice on overcoming common difficulties researchers face.
